Frozen evaporator coil or ice on the refrigerant lines

Squealing or grinding from the blower assembly
Dead or bulging run capacitor on the condenser
Heating and air conditioning service built around Mount Hamilton
Most of the work we do in Mount Hamilton starts the same way: the system is running but the house is not comfortable. Before we replace anything, we measure airflow, static pressure and temperatures so you are paying for the actual fault.
Around Mount Hamilton, condensate drainage is a recurring fault. Blocked drains and failed float switches cause more water damage claims here than actual refrigerant failures do.
Heating season here is November through February. A pre-season inspection catches cracked heat exchangers and failing igniters before the first real cold snap.

Mount Hamilton95140 HVAC questions, answered
Do you service commercial and light commercial properties?
Yes. Around Mount Hamilton 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.
Why is my system short cycling?
Short cycling in Mount Hamilton most often comes from a restricted airflow path — a loaded filter, a closed register, an undersized return — or from an oversized unit. It can also be a failing flame sensor or a pressure switch fault. We measure static pressure and temperature rise before concluding anything, because guessing at this one is expensive.
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 Mount Hamilton, and we recommend a working CO alarm on every level of the home regardless of who services your equipment.
Can you give me a price over the phone?
We can give you realistic ranges — and this page lists the ones homeowners in Mount Hamilton 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.
What brands do you service in Mount Hamilton?
All of them. Our 95140 technicians are trained on York, Amana, Goodman, Lennox and essentially every other residential brand sold in California, including discontinued lines. We keep a broad parts catalogue on the trucks for exactly that reason.
What causes water to leak from the indoor unit?
Almost always a blocked condensate drain line, a failed drain pan float switch, or a frozen coil melting faster than the pan can handle. In Mount Hamilton we see algae and dust clogging drain lines constantly during May through October. It is a fast fix but ignoring it ends in ceiling damage.
