**Primary question this article answers:** How do air-source heat pumps actually work in coastal San Diego homes?

A plain-language walkthrough of how heat pumps move heat (rather than create it), why coastal North County's mild climate is a strong fit, and what the 2023 SEER2/HSPF2 rating change means for new equipment.

### Why Your AC Is Blowing Warm Air: 7 Causes and What to Do

URL: https://earthairsystems.com/learning-center/why-ac-blows-warm-air
Tier: Learn · Reviewed by Remington Hearen (Owner & Founder, Earth Air Heating & Cooling) · Last updated 2026-06-22 · ~6 min read

**Primary question this article answers:** Why is my AC blowing warm air?

The honest diagnostic: thermostat settings, dirty filters, frozen coils, and refrigerant leaks — plus which fixes take five minutes and which need a pro.

**Frequently Asked Questions:**

- **Q: Why is my AC blowing warm air?**
  A: AC blowing warm air falls into two buckets: quick fixes you can do yourself in five minutes (thermostat misconfiguration, dirty filter, debris on the outdoor unit), and real problems that need a licensed technician (frozen evaporator coil, refrigerant leak, failed capacitor, compressor failure, ductwork issue).
- **Q: Should I keep my AC running while I troubleshoot?**
  A: No. Turn the system off at the thermostat. Running a system with a frozen coil or other failure can damage the compressor — a small problem becomes a big one.
- **Q: Can I fix a frozen evaporator coil myself?**
  A: You can thaw it by turning the AC off and leaving the fan on for 30–60 minutes, but you cannot fix what caused the freeze (low refrigerant or restricted airflow) without a tech. Running a frozen system damages the compressor.
- **Q: When does AC trouble mean it's time to replace?**
  A: If your unit is 12+ years old, running R-22 (banned) or aging R-410A with chronic leaks, and the repair quote is more than half what a new system costs, the math usually favors replacement — especially with current SDG&E and federal incentives where eligible.

**Primary question this article answers:** Should I get a second opinion before signing my HVAC quote?

Why second opinions catch oversold scope, missed rebates, and undersized systems — and how Earth Air's no-obligation review works when you've already received a quote from another San Diego HVAC company.

**Frequently Asked Questions:**

- **Q: Should I get a second opinion on my HVAC quote?**
  A: HVAC is a 12–20-year decision most homeowners make 1–3 times in their life. A second opinion takes about 20 minutes and routinely uncovers thousands of dollars in over-quoted scope or missed rebates.
- **Q: What does Earth Air review in a second-opinion?**
  A: We check the sizing (was a real Manual J load calculation done?), equipment selection vs current SDG&E and TECH Clean California eligible-equipment lists, permits and Title 24 compliance, duct sealing, current rebate eligibility, and the 2025 R-454B/R-32 refrigerant transition.
- **Q: How much does a second opinion cost?**
  A: Free, with no obligation. If the quote you have is good, we'll tell you that. If it's off, we'll send a written review explaining what's wrong and what to ask.
- **Q: Will Earth Air try to undercut the other contractor?**
  A: No. This is not a competitive teardown or pressure-switch tactic. We review the quote, not the technician. If our number would be materially different, you get our quote alongside for comparison — no pressure to switch.

### Replace Your AC: Rebate Concierge for SDG&E Customers

**Primary question this article answers:** How do I stack rebates and incentives when I replace my AC or heat pump?

What's currently active (SDG&E rebates, federal credits where eligible) and what's reserved (HEEHRA single-family as of Feb 2026, TECH Clean California reservations, 25C ending Dec 31, 2025). Earth Air handles the paperwork — you keep the savings.

**Frequently Asked Questions:**

- **Q: Is the federal 25C tax credit still available for HVAC in 2026?**
  A: No. Section 25C ended for equipment placed in service after December 31, 2025 per the One Big Beautiful Bill Act (P.L. 119-21). If your install completed in 2025, you may still claim on your 2025 federal return (IRS Form 5695). New 2026 installs do not qualify. This is general information, not tax advice.
- **Q: Are HEEHRA heat pump rebates still available in California?**
  A: No new applications. Single-family HEEHRA rebates were fully reserved statewide as of February 24, 2026. Waitlisted projects have no guaranteed funding. Multifamily HEEHRA may differ — verify at techcleanca.com.
- **Q: What HVAC rebates ARE still available for SDG&E customers in 2026?**
  A: SDG&E utility rebates remain the most reliably active layer — applied as instant rebates through participating contractors when equipment meets program efficiency tiers. Manufacturer factory rebates (Trane, Carrier, Lennox, Rheem, Daikin, Mitsubishi) cycle seasonally. Verify amounts at sdge.com/rebates before signing.
- **Q: What is Earth Air's rebate concierge service?**
  A: We do an eligibility check before quote (pulling current programs you qualify for), recommend equipment that maximizes eligibility, file the SDG&E and manufacturer rebate paperwork for you, and provide tax-credit documentation you can hand your tax preparer if any state-level credit applies in a future year.
- **Q: How much can I realistically save on rebates in 2026?**
  A: For a typical North County home replacing a gas furnace + AC with a high-efficiency heat pump in 2026, the active stack lands roughly $500–$2,500 from SDG&E and manufacturer rebates combined. The $5,000–$10,000 stacks possible in 2024–2025 with 25C and HEEHRA are no longer available. Anyone quoting that level today is selling expired or reserved programs.

### HVAC Permits & Code Compliance in San Diego County

**Primary question this article answers:** Do I need a permit for HVAC work in Oceanside or San Diego County?

What Title 24 requires, which AHJs cover Earth Air's service area (City of Oceanside, Carlsbad, Vista, San Diego County DPDS), what fails inspection most often, and how Earth Air pulls permits and manages inspections so the homeowner doesn't have to.

**Frequently Asked Questions:**

- **Q: Do I need a permit for HVAC work in San Diego County?**
  A: Yes for nearly every HVAC change: replacing a furnace, AC, or heat pump (even like-for-like swaps), installing or modifying mini-splits, adding/changing ductwork, switching fuel source (gas to electric), or replacing major refrigerant line sets. Routine maintenance, filter changes, and capacitor swaps typically don't.
- **Q: Who is the AHJ for HVAC permits in Earth Air's service area?**
  A: City of Oceanside, City of Carlsbad, City of Vista, City of San Marcos, City of Encinitas, and City of San Diego each have their own building department for incorporated areas. The County of San Diego Department of Planning & Development Services (DPDS) covers unincorporated areas like Bonsall, parts of Fallbrook, Valley Center, and unincorporated Rancho Santa Fe.
- **Q: What gets reviewed during a permitted HVAC inspection?**
  A: Title 24 compliance (SEER2/HSPF2 minimums, Manual J load calc, duct sealing tests typically targeting ≤5% leakage), mechanical code (clearances, condensate, combustion air), electrical code (disconnect within sight, properly sized circuit, GFCI), plumbing code for condensate connections, and refrigerant handling per EPA Section 608.
- **Q: What fails HVAC inspection most often?**
  A: Duct leakage test failure (the #1 cause), missing or undersized condensate drain on attic-mounted air handlers, missing electrical disconnect at the unit, combustion-air violations on gas furnace retrofits, and missing Title 24 compliance documentation.
- **Q: Why is unpermitted HVAC work risky?**
  A: Buyer's inspectors flag it at resale (you may have to bring the install up to code retroactively before closing), insurance can deny fire/flood claims that trace back to unpermitted work, manufacturer warranties typically require a licensed-contractor install, and SDG&E rebates almost always require a permit number.

## HVAC Glossary — flattened terms

Source: https://earthairsystems.com/glossary

### Equipment & System Types

- **Air Conditioner (Central) (AC)** — A split-system that cools your whole home by moving heat from indoor air to an outdoor condenser, using an indoor evaporator coil and refrigerant loop connected to ductwork. Coastal North County and inland valleys both run AC hard in summer - but mild winters mean many Oceanside and Carlsbad homes can replace aging central AC with a heat pump instead of AC-plus-furnace, often with better efficiency and access to utility incentives.
- **Heat Pump (Air-Source) (ASHP)** — A system that heats and cools by moving heat with refrigerant - like an air conditioner in summer, and reversed in winter to pull heat from outdoor air into your home. San Diego County's mild coastal climate is well suited to air-source heat pumps; Title 24 increasingly favors electric heat, and state programs like TECH Clean California were built around heat pump adoption (verify current funding before planning your budget).
- **Mini-Split / Ductless** — A heat pump with a compact outdoor condenser and one or more wall- or ceiling-mounted indoor heads - no central ductwork required. Older Oceanside, Vista, and Encinitas homes with no ducts, garage conversions, and ADUs are common candidates; right-sizing each zone separately often beats forcing air through leaky attic ducts in a mild climate.
- **Furnace (Gas Furnace)** — A combustion heater that burns natural gas (or propane) to warm air through a heat exchanger, then sends that air through ductwork - separate from the cooling side in most split systems. Many inland San Diego County homes still heat with gas furnaces, but Title 24 and California's building electrification direction push new and replacement projects toward heat pumps; a dual-fuel system is one transition path.
- **Heat Exchanger** — The metal chamber inside a furnace (or within some air handlers) where combustion heat transfers to your breathing air without mixing exhaust gases with indoor air. A cracked heat exchanger is a safety issue that can trigger a red-tagged shutdown during a permit inspection or tune-up - common reason inland homeowners replace an aging furnace rather than repair.
- **Variable-Speed Compressor** — A condenser compressor that adjusts its output in small steps (or continuously) instead of only full-on or full-off, matching cooling or heating demand more precisely. Coastal mild loads and shoulder-season evenings reward variable-speed operation - better humidity control, quieter run times, and higher SEER2 / HSPF2 ratings that may qualify for SDG&E rebate tiers (verify current equipment lists).
- **Dual-Fuel System / Hybrid Heat** — A heat pump paired with a furnace (usually gas) that switches to the furnace when outdoor temperatures drop below an economic balance point. Less common on the coast than inland (Ramona, Escondido, Fallbrook), but hybrid setups can make sense where occasional cold snaps meet existing gas infrastructure - ask whether Title 24 and your AHJ treat the project as a heat pump replacement or a mixed-fuel install.
- **Air Handler** — The indoor cabinet that moves conditioned air through your ducts - housing the evaporator coil, blower motor, and often the filter rack in a central split-system setup. Attic-mounted air handlers are standard in North County tract homes; poor insulation around the cabinet and high static pressure from restrictive MERV filters are frequent comfort complaints in SDG&E territory.
- **Condenser (Outdoor Unit)** — The outdoor component of a split-system air conditioner, heat pump, or mini-split that releases absorbed heat to the outside air via a compressor and coil. Salt air in Oceanside, Carlsbad, and coastal South OC accelerates coil corrosion - clearance, pad level, and coastal-rated coatings matter; new units ship with lower-GWP refrigerant (R-454B or R-32) per federal and California rules.
- **Evaporator Coil** — The indoor coil where refrigerant evaporates and absorbs heat from your home's air - mounted inside the air handler or a duct plenum on central systems, or inside each mini-split head. A dirty or frozen evaporator coil causes weak cooling and humidity problems common when inland valleys hit 90F+ while coastal zones stay humid - often traced to airflow or refrigerant leak issues.
- **Refrigerant** — The regulated fluid inside your condenser and evaporator coil that carries heat - historically R-410A in most residential systems, now transitioning to lower-global-warming-potential (GWP) alternatives. New residential equipment manufactured after January 1, 2025 must use refrigerants with GWP below 700, primarily R-454B or R-32. Both are A2L (mildly flammable) and require updated installation practices. You're not required to replace a working R-410A system - but refrigerant leak repairs on older R-410A units are getting more expensive as supply tightens under the federal AIM Act. *Note:* 2025 transition: New residential systems use R-454B or R-32 (lower GWP). Working R-410A systems can still be serviced. Never mix refrigerant types.

### Performance & Efficiency Ratings

- **SEER2 (Seasonal Energy Efficiency Ratio 2)** — The current U.S. rating for how efficiently an air conditioner or heat pump cools over a typical season - higher SEER2 means less electricity per unit of cooling. SEER vs SEER2: in 2023, the Department of Energy changed the lab test procedure (including higher external static pressure), so SEER2 numbers run lower than old SEER ratings for the same equipment - a '16 SEER' from 2020 is not apples-to-apples with '16 SEER2' today. Title 24 and SDG&E rebate equipment lists reference SEER2.
- **AFUE (Annual Fuel Utilization Efficiency)** — The percentage of a furnace's fuel that becomes usable heat in your home over a heating season - the rest exits the flue as waste. An 80% AFUE furnace sends 20 cents of every dollar out the vent; 95%+ condensing furnaces recover more heat but still burn gas. With short heating seasons in coastal San Diego, compare AFUE upgrades against switching to a heat pump on SDG&E electric rates.
- **HSPF2 (Heating Seasonal Performance Factor 2)** — The post-2023 efficiency rating for how much heat a heat pump delivers per unit of electricity across a heating season - the heating counterpart to SEER2. Mild winters mean San Diego heat pumps often run at part load, where variable-speed units shine; HSPF2 minimums under Title 24 and federal standards apply to new installs - confirm the rating on the AHRI certificate for your specific model and rebate eligibility.
- **EER2 (Energy Efficiency Ratio 2)** — A snapshot efficiency rating for cooling at a high outdoor temperature and fixed test conditions - it reflects peak-load performance rather than the seasonal average captured by SEER2. Inland North County (Escondido, San Marcos, Fallbrook) and South OC foothills see hotter peak afternoons than the coast; EER2 helps compare how systems perform when you need maximum cooling, not just mild-day averages.
- **Tonnage (Ton of Cooling)** — A unit of cooling capacity - 1 ton = 12,000 BTU/hr - describing how much heat an air conditioner or heat pump can remove per hour, not the equipment's weight. Oversized systems short-cycle, leaving humidity behind in coastal zones; undersized systems struggle on inland heat waves. Right-sizing via Manual J load calculation beats guessing 'a 3-ton for every 1,500 sq ft.'
- **BTU (British Thermal Unit)** — A measure of heat energy - in HVAC, used to describe heating output, cooling capacity (tonnage), and how much conditioning your home needs. Load calculations in San Diego County account for solar gain through west-facing glass, mild winter design temperatures, and ventilation needs - BTU/hr totals from a proper Manual J drive equipment selection and permit compliance.
- **Manual J Load Calculation (Manual J)** — The industry-standard method (ACCA Manual J) for calculating how much heating and cooling a specific home needs based on size, insulation, windows, orientation, duct location, and local climate data. Title 24 requires compliant load calculations for new and replacement HVAC in California; a Manual J prevents the oversizing that wastes money on SDG&E bills and worsens humidity control near the coast.
- **Right-Sizing** — Selecting HVAC equipment whose capacity matches your home's actual load from a Manual J calculation - not oversized 'just to be safe' and not undersized to cut upfront cost. In Oceanside and coastal Carlsbad, an oversized AC cools the thermostat quickly but leaves clammy air; inland, undersized units fail on peak days. Right-sizing pairs with proper duct sealing and static pressure design.

### Indoor Air Quality

- **MERV Rating (Minimum Efficiency Reporting Value)** — A scale (typically MERV 1-16 for residential) rating how effectively an air filter captures particles - higher MERV catches smaller dust, pollen, and some mold spores, but also increases airflow resistance. Wildfire smoke, coastal pollen, and inland dust make MERV 11-13 popular in San Diego County - but jamming a high-MERV filter into an undersized return without checking static pressure can starve your air handler and freeze the evaporator coil.
- **HEPA (High-Efficiency Particulate Air)** — A filter standard that captures at least 99.97% of particles 0.3 microns in size - tighter than any practical standalone MERV residential filter (MERV 16 is close but not identical to true HEPA). True HEPA usually lives in a dedicated whole-house air purifier or portable unit, not a standard 1-inch furnace slot - important for North County homeowners managing allergies or post-wildfire smoke without choking system airflow.
- **UV-C Germicidal Lamp** — An ultraviolet light installed inside the air handler or duct that damages mold, bacteria, and some virus DNA on surfaces and in passing air - it supplements filtration; it does not replace it. Coastal humidity and condensate at the evaporator coil can support mold growth in attic air handlers common across Vista and San Marcos; UV-C is a targeted add-on Earth Air and other contractors often pair with tune-ups.
- **ERV (Energy Recovery Ventilator)** — A ventilator that brings in fresh outdoor air and exhausts stale indoor air while transferring both heat and moisture between the two airstreams - reducing the energy penalty of ventilation. Tight, insulated California homes built under Title 24 can trap CO2 and VOCs; in humid coastal zones (Encinitas, Del Mar), an ERV pre-conditions incoming air better than a plain fan - unlike an HRV which transfers heat only.
- **HRV (Heat Recovery Ventilator)** — A ventilator that exchanges stale indoor air for fresh outdoor air while transferring heat (not moisture) between the two streams - improving ventilation efficiency in heating-dominated climates. HRVs are less common than ERVs along the San Diego coast where moisture transfer matters; they appear more in drier inland pockets or where winter heating ventilation loads dominate on SDG&E gas-electric dual-fuel homes.
- **Latent Cooling vs Sensible Cooling** — Sensible cooling lowers air temperature; latent cooling removes moisture (humidity) by condensing water on the evaporator coil - total cooling capacity includes both. Coastal SDG&E customers often feel 'cold but clammy' when a system delivers sensible cooling without enough latent removal - a right-sizing and variable-speed compressor issue as much as a thermostat setting, especially May-gray and June-gloom weeks.
- **Humidity / Dehumidification** — Humidity is moisture in your air; dehumidification removes it - primarily via latent cooling through your AC or heat pump, or through a dedicated dehumidifier. Marine-layer mornings in Oceanside and Carlsbad keep relative humidity high even when temperatures stay mild; proper latent/sensible balance and ERV ventilation matter more here than in desert climates.
- **Whole-House Air Purifier** — A centralized air cleaning device - often combining high-efficiency filtration (MERV or HEPA), UV-C, or electronic capture - installed in the ductwork or air handler to treat all conditioned air. Earth Air and other IAQ-focused contractors in North County often spec whole-house purifiers for homeowners balancing wildfire smoke seasons, pet dander, and tight Title 24 building envelopes - distinct from a basic 1-inch furnace filter.

### Ductwork & Airflow

- **Static Pressure** — The resistance to airflow inside your ducts and equipment, measured in inches of water column - think of it as how hard your blower must push air through filters, coils, and duct bends. High static pressure from undersized returns, crushed flex duct in hot attics, or overly dense MERV filters is a top cause of noise, weak airflow, and premature blower failure in San Diego tract homes with attic air handlers.
- **Duct Sealing** — Closing leaks in your supply and return ductwork - with mastic, metal tape, aerosol sealant, or replacement sections - so conditioned air reaches rooms instead of your attic or crawlspace. Title 24 requires duct leakage testing on many new and altered systems in California (commonly targeted at <=5% leakage on new installs in unconditioned space); leaky attic ducts in older Oceanside and Vista homes can waste 20-30% of cooling before it reaches living areas.
- **Insulation R-Value (HVAC-Relevant)** — R-value measures thermal resistance - in HVAC contexts, it applies to attic/crawlspace insulation around your living space and to duct insulation wrapping ducts that run through unconditioned attics or garages. Title 24 sets minimum R-values for attics (commonly R-38 to R-49 depending on climate zone) and requires duct insulation in unconditioned space; in North County, under-insulated ducts in 130F+ attics heat-cool the air before it reaches your registers.

### California Incentives & Code

- **Title 24 (California Building Energy Efficiency Standards)** — California's building energy code - updated on a three-year cycle by the California Energy Commission - setting minimum efficiency, ventilation, and installation requirements for HVAC, insulation, and lighting in new construction and most replacements. Every HVAC permit in San Diego County must meet current Title 24 - including Manual J load calculation, minimum SEER2 / HSPF2, duct sealing tests, and heat pump requirements in many replacement scenarios. Your AHJ enforces it at inspection.
- **TECH Clean California** — California's statewide heat pump incentive program - administered with utility partners - that provides rebates for qualifying heat pump and heat pump water heater installations through TECH-certified contractors. TECH was a primary rebate stack layer for SDG&E customers alongside utility incentives. As of early 2026, single-family heat pump HVAC reservations through TECH Clean California are fully reserved statewide - verify current status at techcleanca.com and switchison.org before budgeting. *Note:* Verify status: TECH Clean California single-family heat pump HVAC reservations were fully reserved statewide in early 2026.
- **Federal 25C Tax Credit (Energy Efficient Home Improvement Credit)** — A federal income-tax credit (IRS Section 25C) that covered 30% of qualifying energy-efficiency upgrades - including heat pump installations - subject to annual caps. Through December 31, 2025, qualifying air-source heat pumps were capped at $2,000 per year, with a $1,200 combined cap for other eligible improvements. Federal law (the One Big Beautiful Bill Act, P.L. 119-21) ended Section 25C for equipment placed in service after December 31, 2025 - new 2026 installs generally do not qualify. If your system was placed in service by December 31, 2025, you may still claim on your 2025 federal return (IRS Form 5695). General information, not tax advice. *Note:* Section 25C ended December 31, 2025. Equipment placed in service after that date generally does not qualify.
- **SDG&E Rebate (San Diego Gas & Electric)** — Utility incentives from SDG&E for qualifying high-efficiency HVAC equipment - typically applied as an instant rebate through participating contractors when equipment meets program efficiency tiers. SDG&E rebates are often the most accessible active layer for North County and San Diego County homeowners when state programs are reserved. Amounts vary by equipment type, efficiency (SEER2 / HSPF2), and whether you're switching from gas - verify current dollar amounts and eligible equipment lists at sdge.com/rebates before signing a contract.
- **HEEHRA (Home Electrification and Appliance Rebates)** — Federal Inflation Reduction Act rebates administered in California through TECH Clean California for income-qualified households installing heat pump HVAC - with tiers based on area median income (AMI). When funding was available, published caps reached up to $8,000 (low-income, below 80% AMI) and $4,000 (moderate-income, 80-150% AMI) for qualifying heat pump HVAC replacements. As of February 24, 2026, single-family HEEHRA rebates are fully reserved statewide and no new income-verification applications are being accepted. Waitlisted projects have no guaranteed funding. Multifamily HEEHRA may differ. *Note:* Critical: Single-family HEEHRA rebates are fully reserved statewide as of February 24, 2026. Do not plan a project around HEEHRA without an already-approved reservation.

### Permitting & Process

- **Permit (HVAC)** — A legal authorization from your local AHJ before installing or substantially altering HVAC equipment - confirming Title 24 compliance, safety clearances, and inspection. Skipping a permit risks failed escrow inspections, insurance denial after a fire, and redo work. In Oceanside, Carlsbad, and unincorporated San Diego County, permitted installs require final inspection before the CSLB-licensed contractor closes the job.
- **AHJ (Authority Having Jurisdiction)** — The local government agency that enforces building codes and issues HVAC permits - usually your city building department or the county if you live in an unincorporated area. Examples in Earth Air's service area: City of Oceanside Building Division, City of Carlsbad Development Services, City of Vista Building Division, and County of San Diego Department of Planning & Development Services (unincorporated areas). Each AHJ has its own submittal process, fees, and inspection timeline.
- **CSLB (Contractors State License Board)** — California's state agency that licenses and regulates contractors - HVAC contractors typically hold a C-20 (Warm-Air Heating, Ventilating, and Air-Conditioning) license, verifiable at cslb.ca.gov. Hiring an unlicensed installer voids most manufacturer warranties, TECH Clean California / SDG&E rebate eligibility, and permit approval. Earth Air Heating & Cooling holds CSLB license #1103686 - always verify any contractor's license status and classification before work begins.
- **NATE Certification (North American Technician Excellence)** — An independent, industry-recognized certification for HVAC technicians - earned by passing knowledge exams in areas like air conditioning, heat pumps, and gas furnaces, with continuing education to maintain. NATE-certified technicians are trained on refrigerant transitions (R-454B / R-32), heat pump commissioning, and Title 24 installation details - a meaningful credential when comparing quotes for complex installs in SDG&E territory.

### Servicing & Maintenance

- **Tune-Up / Preventive Maintenance** — A scheduled service visit - typically annual - where a technician inspects, cleans, and tests your system: coils, drains, electrical connections, refrigerant charge, static pressure, safety controls, and thermostat operation. Coastal salt air corrodes outdoor condenser coils; inland dust clogs filters and drains. A spring tune-up before San Diego's warm season catches refrigerant leak issues early - cheaper than an emergency call when inland valleys hit triple digits.
- **Refrigerant Leak / Refrigerant Recharge** — A refrigerant leak is an escape of refrigerant from the sealed system (often at flare fittings, Schrader valves, or coil cracks); a recharge adds refrigerant back - but without locating and repairing the leak, the problem returns and is illegal to ignore under EPA rules. R-410A recharge costs have risen as production phases down; putting R-410A into a system designed for it remains legal for service, but chronic leaks on aging equipment often tip the math toward a new heat pump with R-454B or R-32. Never mix refrigerant types.
