Heat Pump Installation in Delano, CA
Ducted heat pumps sized for Delano's 100°F afternoons and foggy winter mornings, with the permit and California energy-code testing included in the job.
- Manual J Load Calculation
- Permit & Title 24 Testing
- Ducted & Packaged Systems
We handle heat pump installation in Delano, CA for homes with ductwork or a packaged unit. That covers three jobs: replacing a worn-out heat pump, switching from an air conditioner and gas furnace to one heat pump system, and adding a heat pump to a furnace you want to keep. Every job starts with a Manual J load calculation at your home. It ends with the duct-leakage and refrigerant-charge checks Title 24 requires on a changeout.

Matching the Heat Pump to What You Have Now
The equipment already in your house decides most of the scope.
| What you have now | What we usually install | What we check first |
|---|---|---|
|
An older heat pump
|
What we usually installA new outdoor unit with a matched indoor coil or air handler | What we check firstWhether the line set and ducts can stay |
|
Central AC with a gas furnace you're ready to retire
|
What we usually installA heat pump outdoor unit, plus a new air handler where the furnace was | What we check firstPanel capacity for the air handler and any backup heat |
|
Central AC with a furnace that still has years left
|
What we usually installA heat pump in place of the AC, paired with the existing furnace (dual fuel) | What we check firstWhether the furnace blower and controls work with a heat pump, and the outdoor temperature where heating switches to gas |
|
A rooftop or ground-mounted packaged unit
|
What we usually installA packaged heat pump in the same spot | What we check firstCurb or pad fit and the duct connections at the roof or wall |
Delano's average January low is about 38°F (NOAA 1991–2020 normals), so a correctly sized heat pump can usually handle winter heating without gas. Dual fuel makes the most sense when the furnace is fairly new or the electrical panel has little room for backup heat strips. If the furnace needs replacing anyway, we can look at pairing the heat pump with a new furnace. If you'd rather keep a straight AC with gas heat, see a new central air conditioner instead.
Replacing an Existing Heat Pump in Delano
A heat pump is usually due for replacement when the problem is in the system itself, not in one worn part:
- The compressor or reversing valve has failed on a unit that's out of its parts warranty.
- It runs on R-22, which is no longer produced, so every recharge gets harder to source.
- Winter bills jump because backup heat strips are doing most of the heating on cold, foggy mornings.
- The outdoor coil is corroded, or so packed with field and road dust that cleaning no longer brings airflow back.
- It was oversized at the original install and short-cycles through Delano's mild spring and fall.
What a replacement changes
| Part | Usually reused? | How we decide |
|---|---|---|
| Line set | Sometimes | It must match the size the new unit's manufacturer specifies. If we reuse it, it's flushed with nitrogen, pressure-tested and fitted with a filter drier, following the manufacturer's instructions. Lines that are undersized, kinked or can't be inspected are replaced. |
| Indoor coil or air handler | Rarely | Efficiency ratings only apply to AHRI-matched outdoor and indoor pairs, and new systems run on R-454B or R-32, so the indoor side is normally replaced along with the outdoor unit. |
| Thermostat | Depends | It has to control the reversing valve and backup heat. Title 24 also requires a setback thermostat on a changeout. |
| Condensate drain | Usually changed | A new air handler may sit differently. Attic units get a secondary pan or an overflow switch. |
| Outdoor pad | Often replaced | A raised, level pad keeps defrost meltwater and sprinkler runoff away from the base of the coil. |
How We Size and Select a Heat Pump for Delano
In Delano, cooling sets the size. The city averages about 34 days a year at or above 100°F and about 116 at or above 90°F (NOAA 1991–2020 normals). Our Manual J calculation goes room by room, then we check the result against the heating load.
Two sizing errors cause most comfort complaints.
Oversized
An oversized unit cools quickly on a 90°F day, shuts off, and short-cycles through spring and fall, which wears parts and leaves rooms uneven.
Undersized
An undersized unit runs nonstop and falls behind during a 105°F stretch.
Manufacturers measure cooling capacity at 95°F outdoors, and output drops as the air gets hotter. So we check each model's published performance data at Delano summer temperatures, not just its nominal tonnage.
The options in your proposal differ on four points:
-
Compressor type: single-stage, two-stage or variable-speed. Variable-speed costs more and holds steadier temperatures through long summer run times.
-
Efficiency: federal minimums are 14.3 SEER2 and 7.5 HSPF2 for split heat pumps, and 13.4 SEER2 and 6.7 HSPF2 for packaged units. Cooling does most of the work in Delano, so SEER2 usually has the bigger effect on your bill.
-
Split or packaged: a split system needs indoor space for an air handler (a closet, the garage or the attic). A packaged unit sits on the roof or a ground pad.
-
Matched system: the outdoor unit and the indoor coil or air handler are an AHRI-certified match, so the rated efficiency is the efficiency you get.
Heat Pump Installation Steps, From Booking to Inspection
-
You
Booking.
Reach out through our contact page. Tell us what you have now (a heat pump, an AC with a furnace, or a packaged unit) and its approximate age. Add your home's square footage and any duct or electrical problems you already know about. Include access details such as a gate code, pets, or where the attic hatch is.
-
At your home
Site visit.
A technician takes the Manual J measurements and inspects the ducts, the electrical panel, the outdoor and indoor equipment locations and the thermostat wiring. They also photograph the equipment labels.
-
Your approval
Written proposal.
You get equipment options with model numbers and SEER2/HSPF2 ratings. It also lists the full scope: removal, line set, duct sealing, electrical, thermostat, permit and energy-code testing. Nothing is ordered until you approve it.
-
Paperwork
Permit.
We apply for the mechanical permit with the agency that covers your Delano-area address (see the permits section below).
-
Install
Install day.
EPA Section 608–certified technicians recover the refrigerant from the old system before it comes out. Then we:
- set the outdoor unit and install the coil or air handler
- braze and pressure-test the line set, then pull a vacuum
- wire the circuit and disconnect
- connect the condensate drain and mount the thermostat
-
Tested & verified
Startup and verification.
We verify the refrigerant charge and airflow, run the system in cooling and heating, and force a defrost cycle. A third-party ECC-Rater then verifies the duct-leakage and charge results. (ECC-Rater is the 2025 code's name for a HERS rater.) The city or county inspection follows.
-
Done
Walkthrough and cleanup.
We explain the thermostat, including when backup heat comes on, and register the equipment warranty with the manufacturer. Then we haul away the old equipment and clean the work areas.
Ductwork and Electrical Checks Before the Install
Ductwork
Duct leakage
Title 24 requires sealing and testing when the outdoor unit, coil, air handler or packaged unit is replaced. Exemptions include duct systems under 40 feet and asbestos-wrapped ducts.
Duct size and returns
The code requires at least 300 cfm per ton of airflow on a changeout
Electrical
Panel and service size
The outdoor unit and air handler each need their own circuit, and backup heat adds the most load
Disconnect
Code requires one within sight of the outdoor unit
Most Delano addresses are served by Southern California Edison. Utility-side service upgrades go through SCE's Building, Renovation and Project Planning portal.
Delano Conditions That Change How We Install
-
Summer attics
Through July and August, an air handler in a Delano attic sits in some of the hottest air in the house. Where the floor plan allows, we prefer a hall closet or the garage. If it has to go in the attic, we add a platform and a secondary drain pan, and fully insulate the line set and duct connections.
-
Dust
The San Joaquin Valley is a federal nonattainment area for fine particulates. Delano sits among vineyards and citrus groves on Highway 99, which is being widened between Delano and Pixley. We set outdoor units on raised pads with clear space on every side, away from the most exposed wall where the lot allows. At the air handler, we fit a deeper media filter cabinet so a higher-grade filter doesn't choke airflow.
-
Fog
From November through February, tule fog and near-freezing mornings frost the outdoor coil and set off defrost cycles. Pad height and a clear drainage path keep the meltwater from refreezing around the unit.
-
Housing
About 4% of Delano homes are mobile homes and about 37% are rentals (Census ACS 2020–2024). Manufactured homes need equipment listed for that use and an HCD permit, and a packaged unit is often the practical fit. For rentals, we can coordinate access with both the owner and the tenant.
Heat Pump Brands We Install
- Carrier
- Goodman
- Lennox
We install Carrier, Goodman and Lennox heat pumps. Every proposal lists exact model numbers so you can compare quotes line by line. Before we recommend a model, we check its published capacity at Delano summer temperatures.

Permits, Title 24 and Refrigerant Rules in Delano
Permit
- City of Delano addresses: City building permit.
- Unincorporated Kern County: Kern County Public Works.
- North of the Kern–Tulare county line: Tulare County Resource Management Agency.
- Manufactured and mobile homes: California HCD.
Title 24 2025 Energy Code, Climate Zone 13
Replacing the outdoor unit, coil, air handler or packaged unit triggers duct sealing and leakage testing, refrigerant charge and airflow verification, and a setback thermostat. Replacing the full system also requires a load calculation.
Field verification
A third-party ECC-Rater (formerly HERS Rater) verifies the test results.
Refrigerant
New residential split systems use lower-GWP refrigerants such as R-454B or R-32. Refrigerant from the old system must be recovered by EPA Section 608–certified technicians.
Contractor license
California puts heat pump HVAC installation under the C-20 contractor license.
Questions About Installing a Heat Pump in Delano
Can I replace just the outdoor unit of my heat pump?
Sometimes. It depends on whether a matched outdoor unit is still made for your existing indoor coil. Most new outdoor units use R-454B or R-32 and are only efficiency-rated with specific indoor matches. We'll show you whether a partial swap is possible, and what it gives up, before you decide.
Will my existing ductwork work with a new heat pump?
Often, as long as it can carry the airflow the new system needs (at least 300 cfm per ton under Title 24) and passes leakage testing after sealing. Original attic ducts in older Delano homes are the most likely to need sealing or repairs. Asbestos-wrapped ducts are exempt from the leakage test but need a different plan.
Do I need a bigger electrical panel for a heat pump?
Not always. The outdoor unit and air handler each need a dedicated circuit, and electric backup heat adds the most load. Delano winters are mild, so we size backup heat to what the house needs, then check the panel's spare capacity before recommending an upgrade.
Can I add a heat pump and keep my gas furnace?
Yes, that's a dual fuel setup. The heat pump replaces the air conditioner and handles cooling and most heating. The furnace takes over below an outdoor temperature set at the thermostat. It works best when the furnace is in good shape and its blower can move the airflow the heat pump needs.
Do I need a permit to replace a heat pump in Delano?
Yes. A heat pump replacement needs a mechanical permit and the Title 24 tests described above. The permit comes from the City of Delano, Kern County or Tulare County depending on your address, or from California HCD for a manufactured home.
What refrigerant will a new heat pump use?
Most new residential split heat pumps use R-454B or R-32. Both meet EPA limits on high-GWP refrigerants. Both are classed A2L (mildly flammable), so they require specific installation practices. The proposal lists the refrigerant for each model we quote.
Can you size a heat pump from my home's square footage?
No. Square-footage rules of thumb tend to oversize. A Manual J calculation accounts for windows, insulation, orientation, and where the ducts run. In Delano, two homes of the same size can need different tonnage because of west-facing glass or attic ducts.
Will a heat pump keep my house cool when it's 105°F in Delano?
A correctly sized one is built to. Cooling ratings are measured at 95°F outdoors, and output drops in hotter air. That's why we size from the manufacturer's performance data at Delano summer temperatures, not from nominal tonnage alone.
Are there heat pump rebates or tax credits in Delano right now?
Availability shifts by program and by address, so we check what applies to your home during the evaluation instead of promising a rebate up front.
Why do heat pump installer quotes in Delano vary so much?
Quotes often cover different scopes. One may reuse the old coil and leave out duct sealing. Another may include a matched air handler, duct sealing, the permit and ECC-Rater verification. Compare model numbers and line items, not just the total.
Can a heat pump be installed in a manufactured or mobile home in Delano?
Yes, with equipment listed for manufactured-home use. A packaged heat pump is often the practical fit. The permit goes through California HCD rather than the city.
