The short answer
AllPro HVAC Services repairs, installs, and maintains air conditioners, furnaces, heat pumps, and ductless mini-splits for Westmont homeowners, with 24/7 emergency service available. Before replacing equipment, check South Coast AQMD furnace rules and confirm which utility serves your address, since that determines available rebates.
AllPro HVAC Services works on heating and cooling systems for homeowners in Westmont, the unincorporated Los Angeles County community about 11 miles southwest of our Los Angeles base. We repair air conditioners, furnaces, and heat pumps, install new systems including ductless mini-splits, and handle routine maintenance, duct cleaning, and indoor air quality work. When a system quits on a hot afternoon or a cold night, we offer 24/7 emergency service. This page explains what we do in Westmont, how local climate and regulations affect your options, and what to know before you replace equipment.
Heating and Cooling Repair for Westmont Homes
Los Angeles has a Mediterranean climate with dry summers and mild winters, so many Westmont homes lean on air conditioning for months at a time and run the furnace or heat pump only on cooler evenings and winter nights. That pattern means AC parts wear steadily through summer, while heating equipment can sit unused for long stretches and then struggle when it is finally switched on.
Fall Santa Ana winds can bring hot, dry spells well after summer seems over. Those stretches put extra load on air conditioners that may already be tired from the season, and they are a common time for breakdowns. If your system stops working, we offer 24/7 emergency service.
- AC repair: weak airflow, warm air, frozen coils, refrigerant problems, and units that will not start
- Furnace repair: ignition and pilot issues, short cycling, unusual smells or noises, and blower failures
- Heating repair for heat pumps and other systems that are not keeping the house comfortable
- Thermostat and electrical diagnosis when the problem is not the equipment itself
New Systems: AC, Heat Pumps, Furnaces, and Mini-Splits
When repair no longer makes sense, we help you compare replacement options based on your home's layout, existing ductwork, and how you actually use heating and cooling. A central AC paired with a furnace is still common, but many homeowners now look at heat pumps, which provide both cooling and heating from one system and suit the region's mild winters well.
Ductless mini-splits are a practical choice for homes without ducts, for additions and converted garages, or for rooms that never stay comfortable on the central system. Each indoor head is controlled separately, so you can cool or heat only the spaces you use.
If you are planning to replace a gas furnace, note that South Coast AQMD Rule 1111 limits NOx emissions from natural-gas fan-type central furnaces sold and installed in the Los Angeles region. The district has been amending the rule toward zero-emission requirements and sets and revises the compliance dates, so check the current version of the rule before you decide. We can walk through how it may affect a furnace versus a heat pump for your home.
Rebates and Incentives: What Applies in Westmont
Which equipment rebates you can get depends on the utility that serves your address. Many homes outside the City of Los Angeles are served by Southern California Edison rather than LADWP, and because Westmont is unincorporated, it is worth confirming your utility before counting on any particular offer. We confirm the current rebate before quoting it.
For homes served by LADWP, residential electric customers can apply for Consumer Rebate Program rebates on qualifying heat pump HVAC systems. The amount is based on the unit's SEER2 and HSPF2 ratings, and the application is filed after the equipment is purchased and installed, within 12 months of purchase.
The federal Energy Efficient Home Improvement Credit (25C) covered qualifying heat pumps placed in service before December 31, 2025. It is not available for new installations after that date, so do not plan a project around it.
Maintenance, Duct Cleaning, and Indoor Air Quality
Regular HVAC maintenance catches small problems, such as dirty coils, clogged filters, and worn electrical parts, before they turn into a failure during a heat wave. A good schedule is a cooling check before summer and a heating check before the cooler months.
Dry weather and wind-driven dust can load up filters and ductwork faster than you might expect. Duct cleaning removes buildup that restricts airflow and recirculates through the house. For households dealing with dust, allergies, or stale air, we also offer indoor air quality options such as improved filtration.
