Get your free estimateFast, Reliable AC Installation Across Pomona
Most full AC installations in Pomona run between $3,500 and $7,500, and the biggest mistake we see is treating an older home like a newer one. Pomona’s housing stock is dominated by 1940s to 1960s slab-on-grade tract homes, and those houses were built for floor furnaces, not central air. That means a real installation here is often a retrofit, not a swap. Our AC Installation team knows exactly what that involves: ductwork that has to be sealed or replaced, electrical panels that need upgrading, and load calculations that account for uninsulated walls and tight attics. If you’re in Pomona and your AC is struggling or you’re installing central air for the first time, call us at (831) 607-5485. We’ll give you a written fixed price before any work starts.
Why Halden Heating and Air West Covina Is Pomona’s Preferred AC Installation Company
Pomona homeowners call us because we treat a 1958 rancher differently than a 2018 build. Andre Fuller, who leads our team, has spent enough time in Pomona attics to know that no two retrofits are the same. We do not show up with a one-size-fits-all system and hope for the best. We measure the house, check the ductwork, confirm the panel, and then put a price in writing. That price does not change at the door.
We also run on the Relay Visibility Guarantee. You book online, you get a live arrival time, and you track your technician to the door. No four-hour windows. No phone tag. If you call at midnight because the AC quit, a real person answers. Every job comes with the 365-Day Done Right Promise and a written guarantee on every repair. If something is not right within the coverage window, we come back at no charge, automatically.

HVAC Installation in Pomona
HVAC installation in Pomona is different from installation in almost any neighboring city, because so many homes here were built on slab foundations with floor furnaces between 1940 and 1970. That means there is often no existing ductwork suitable for central air. The job involves sizing the system with a proper load calculation, designing and sealing ductwork, upgrading the electrical panel if needed, and installing the outdoor condenser and indoor air handler. A straightforward HVAC installation in Pomona runs $3,500 to $7,500, though retrofits on older homes may need additional duct or panel work, which we quote separately and in writing before anything begins.
Ductwork and Airflow in Slab-on-Grade Homes
In a slab-on-grade house, there is no basement and no crawlspace. Ducts go through the attic, which in Pomona summers can hit 140°F or more. Leaky or undersized ducts in that heat waste a huge amount of cooling. We routinely find original metal ductwork from the 1950s that has separated at the seams, pulling hot attic air into the system. Sealing or replacing those ducts is usually not optional if you want the new AC to actually cool the house.
Electrical Panel Upgrades for Modern Systems
Many Pomona homes still run on 100-amp panels, which were fine for a floor furnace and a few lights. A modern central air system, especially a heat pump, can push that panel past its safe limit. We check panel capacity as part of every installation quote and tell you honestly whether an upgrade is needed before the new equipment goes in. Skipping this step leads to tripped breakers on hot days, and sometimes worse.
Heat Pump Installation in Pomona
Heat pump installation in Pomona makes a lot of sense because it handles both cooling and heating in one system, and Pomona winters do dip into the 30s at night. A heat pump is often the better choice for an older slab-on-grade home, because it does not need a gas line and it runs efficiently even when temperatures swing from 95°F in August to 38°F in January. Heat pump installation in Pomona falls within the same $3,500 to $7,500 range as a traditional AC, depending on the size and whether ductwork needs work. We install heat pumps from Rheem, Daikin, and Bryant, among others.
Why Heat Pumps Fit Pomona’s Climate
Pomona has hot, dry summers and cool, occasionally near-freezing winter nights. A heat pump handles both without a separate furnace, which simplifies the install and reduces the number of systems you have to maintain. For a homeowner replacing an old evaporative cooler or a gravity wall heater, a heat pump is often the cleanest path to real comfort.
Heat Pump Retrofits for Older Homes
Older Pomona homes often need more than just the heat pump itself. We commonly find that a heat pump retrofit includes sealing attic ducts, replacing an undersized return, and sometimes upgrading the electrical panel. In the Wilton Heights area, we installed a 3-ton Carrier heat pump for a 1950s single-story home after a load calculation showed the original ductwork was leaking 30% of airflow. Our techs sealed the attic ducts, replaced the undersized return, and upgraded the 100-amp panel at the same time, so the new SEER2-rated system finally held 72°F on a 100°F day.
Trusted Brands We Service in Pomona
We install and service major brands including Rheem, York, Daikin, and Bryant, and we carry the most common parts for these systems close to Pomona so we are not waiting on a warehouse across the county when your AC needs attention.

AfterCommon AC Installation Problems We See in Pomona Homes
- Original floor-furnace ductwork that cannot handle central air. Homes built in the 1950s and 1960s were not designed for forced-air cooling. The ducts are often too small, uninsulated, and leaking at the seams. A new AC installed on top of that ductwork will run constantly and never cool evenly.
- Wrong tonnage from skipping the load calculation. We see handymen and even some contractors guess the system size. In a slab-on-grade home with no insulation in the walls, guessing wrong means short cycling, poor humidity control, and a blower motor that dies early from high static pressure.
- Electrical panels that cannot support a modern system. A heat pump or larger central AC draws more amps than a 100-amp panel from the 1960s was built to supply. Continuing to run an overloaded panel is a fire hazard. We always check this before installation.
- Asbestos-wrapped ducting from mid-century retrofits. Homeowners in older Pomona neighborhoods sometimes discover old asbestos wrap on ductwork that was added decades after the house was built. We never cut into that material. We bring in a licensed abatement professional and handle the situation safely before proceeding.
Pricing for AC Installation in Pomona, CA

FAQs About AC Installation in Pomona
Older Pomona homes were built for floor furnaces, not central air, so the original ductwork is often undersized, uninsulated, and leaking. Installing a new AC on that ductwork wastes energy and shortens the life of the blower motor. We inspect and seal or replace ducts as part of the install. Call (831) 607-5485 if you want us to check your ducts before you commit to a new system.
In most cases, yes. A heat pump handles heating and cooling in one unit, which fits well with Pomona’s mild winters and hot summers. For slab-on-grade homes without gas lines, a heat pump also avoids the need to run new gas piping. We can run a load calculation and tell you if a heat pump makes sense for your specific house.
Many Pomona homes built between 1940 and 1970 have 100-amp panels, which may be too small for a modern heat pump or central AC. We check the panel as part of every free estimate and tell you if an upgrade is required before installation. Do not guess on this one. An overloaded panel is a genuine safety risk, not just an inconvenience.
We stop work and bring in a licensed abatement professional. We never cut, tear, or disturb asbestos-wrapped ducting ourselves. This is something we have encountered in older Pomona neighborhoods where mid-century retrofits added ductwork years after the original construction. The abatement is handled safely and separately, and then we continue with the installation.
Because the old system was probably the wrong size to begin with, and the ductwork has degraded since. Swapping a 3-ton for a 3-ton without a load calculation and without fixing the ducts just recreates the same poor cooling. A real retrofit plan starts with measurements, not guesses. Call (831) 607-5485 and we will start with the load calculation, not a sales pitch.
