A new furnace is one of the longest-lived purchases in your home, and the options multiply quickly. You can choose an 80 percent AFUE unit or a mid-90s condensing model, single-stage, two-stage, or modulating burners, and a standard PSC blower or a variable-speed ECM motor that uses less electricity and evens out temperature swings. Which mix is right depends on your San Mateo, CA home, the length of your heating season, and the behavior of your ductwork. That is why San Mateo HVAC begins with a load calculation rather than copying whatever the previous installer chose. An oversized furnace short-cycles and overshoots, delivering comfort in bursts while it wears itself out. A properly sized one runs longer, quieter, and at lower cost.
The repair homeowners call us about most is Furnace Repair. Start there if your system isn't running right.
Warning Signs for Furnace Installation
The sooner you notice these red flags, the easier and cheaper the fix. These are the signals our technicians see most often:
- The furnace you have is fifteen to twenty years old or more
- Paying more to heat a house that never gets comfortable
- A cracked heat exchanger has been found, ending the repair conversation
- Short cycling, big temperature swings, or rooms the furnace never reaches
- A blower so noisy you have to raise your voice when it runs
- Service calls that come more often and cost more every year
- Booming ignition, rust, or soot that keeps coming back after service
- You are upgrading your cooling system and the aging furnace would hold it back
Early Action Saves Money
What seems like a minor issue today can take out a compressor or heat exchanger tomorrow. If you notice any of these signs, call (650) 220-0817 for a prompt inspection.
