What are signs your AC unit needs to be repaired?
Your AC system needs to be repaired if you see the following signs:
- Rising energy bills: Consistently higher or steadily rising energy bills may indicate your AC system is using more electricity than it should. The average spending on energy is $128 per month in San Mateo, based on data from the Department of Energy (DOE) and U.S. Energy Information Administration (EIA).
- Inconsistent temperatures: Your AC is designed to keep your entire home at a consistent temperature. Big fluctuations in temperature from one room to the next could point to an issue with your HVAC.
- Inaccurate thermostat readings: Your home's internal temperature should match the thermostat. Mismatched temperature readings could point to a problem with your AC system or thermostat.
- Leaks around the AC unit: Moisture around your AC system is a problem that demands professional diagnosis. It could be due to a refrigerant leak or water from a blocked tube.
- Weird noises: AC systems generate some level of noise, but loud sounds or unusual noises, such as screeching, clicking or bubbling, can signal a larger issue.
- Strange odors: Your AC may require a tune-up if it suddenly develops a lingering, unusual scent.
- Weak airflow: If your AC has weak or poor airflow, that's a sign your air conditioning system isn't working properly or that something is blocking the duct or vent.
- Warm air: Warm air indicates a potential problem with your home’s ductwork or that your system's compressor is low on refrigerant.
- Frequent cycles: It's normal for your AC to turn on more often on hotter days, but if it cycles on and off more than usual, your AC may need repairs.

How do you choose the best AC repair company in San Mateo?
Take these factors into account when choosing the best AC repair company for you in the San Mateo area.
Make sure the company is licensed in California
Confirm your AC company is properly licensed and insured before booking. The California Contractors State License Board requires HVAC contractors to maintain proper licensing. They also need a surety or cash bond and worker’s compensation insurance. Additionally, the Environmental Protection Agency (EPA) requires all HVAC pros who handle refrigerants to be certified.
Look for national accreditations
While not mandatory, there are national accreditations for AC pros, such as the Air Conditioning Contractors of America (ACCA) and the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE). Having a certification from one of these professional organizations offers proof of a technician's ability and knowledge in the field.
Get a free estimate
Most AC repair companies provide free estimates. This includes an in-home inspection during which the technician proposes solutions and gives you a quote. Pay attention to how careful and thorough the technician is during the inspection.
Compare costs
Request itemized quotes from multiple providers to compare costs. Reviewing prices from multiple providers will help you find the average local price range. Be wary of pros that have disproportionately high or low rates.
Assess experience
Verify the technician has experience handling your type of AC system. HVAC technicians work with different kinds of heating and cooling equipment, but some have expertise in certain types of systems.
Read reviews
Ask your friends and family for recommendations for local AC repair companies. Always check a company’s online reviews.
When browsing reviews, watch out for consistently bad ones. Make sure you're reading current reviews, as the company's service quality could have changed over the years.
What are popular types of AC units in San Mateo?
These are the types of AC units you can typically find in San Mateo homes, along with which homes they suit best:
- Central: Standard central AC units are reliable and designed to efficiently cool entire homes.
- Ductless mini-split: The ductless mini-split is a efficient choice for homes without ductwork.
- Hybrid: Hybrid systems combine heat pumps with furnaces, providing cooling during hot weather and heating during colder seasons.
- Heat pumps: More San Mateo homeowners use heat pumps, which are more cost-effective in warmer climates.
