Heating and air conditioning service built around Loma Mar
Inland valleys hit extreme heat while coastal zones stay mild, so system sizing matters more here than raw capacity. Our Loma Mar teams are set up for exactly that: rapid response, flat-rate pricing quoted before work begins, and no surprise overtime charge for nights or weekends.
Homes in San Mateo County tend to be a mix of older builds with original ductwork and newer infill construction, which means airflow problems show up very differently from one street to the next.
If your system is over ten years old and you have had two repairs in the last two seasons, a replacement comparison is usually worth running even if the current unit still runs.

Loma Mar94021 HVAC questions, answered
Can you give me a price over the phone?
We can give you realistic ranges — and this page lists the ones homeowners in Loma Mar see most often — but a firm price needs eyes on the equipment. Any company that quotes a final number without seeing the unit is usually quoting low to get through the door.
Are your technicians licensed and insured?
Every technician dispatched into Loma Mar is licensed, insured and background-checked. We can provide proof of insurance on request before the visit if you would like it on file.
Is my carbon monoxide risk something I should worry about?
With any combustion appliance, yes. A cracked heat exchanger can spill carbon monoxide into the living space, and it is odourless. We perform combustion analysis and a CO test on every furnace and boiler call in Loma Mar, and we recommend a working CO alarm on every level of the home regardless of who services your equipment.
Is my system low on refrigerant, or is it leaking?
Refrigerant does not get "used up" the way fuel does. If your charge is low, there is a leak somewhere — usually at a flare connection, a schrader core or the evaporator coil. We locate and repair the leak rather than simply topping up the charge, because a top-up alone will fail again.
Do you service commercial and light commercial properties?
Yes. Around Loma Mar we handle rooftop packaged units, split systems, VRF/VRV installations and building automation faults for offices, retail, restaurants and multi-tenant buildings, including after-hours scheduling so you are not disrupting trade.
Do you offer maintenance plans?
We do. A two-visit plan in California covers a spring cooling inspection and an autumn heating inspection, priority scheduling during peak weeks, discounted repairs and no diagnostic fee. Members rarely end up on the emergency list.
