What are signs your AC unit needs to be repaired?

The following are some signs your AC unit needs repairs:

  • Rising energy bills: The typical local spending on energy is $128 per month, according to data from the U.S. Energy Information Administration (EIA) and Department of Energy (DOE). If your energy bill is much higher or keeps going up, your AC unit may be the culprit.
  • Inconsistent temperatures: When an AC is functioning properly, it maintains a consistent temperature throughout your home. Major temperature fluctuations could mean your HVAC system needs repairs.
  • The internal temperature doesn’t match the thermostat: Discrepancies between your home’s actual temperature and the thermostat’s means there may be an issue with your AC or thermostat.
  • Leaks around the AC unit: Get in touch with an AC repair company as soon as possible if your AC is leaking. This could be leaking refrigerant or water from a damaged or blocked tube.
  • Weird noises: Loud or unusual noises, such as bubbling, clicking or screeching, can mean a larger issue.
  • Strange odors: A smell coming from your AC after going unused for months is normal, but an AC with a lingering or sudden unusual odor may need repairs.
  • Weak airflow: If your AC has poor airflow, that’s a sign your AC isn’t working properly or that something is blocking the duct or vent.
  • Warm air: If your vents blow warm air, there could be an issue with your home’s ductwork, or your system’s compressor is low on refrigerant.
  • Frequent cycles: It’s normal for your AC to turn on more often on warmer days, but if it turns 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 researching AC repair companies in the San Mateo area.

Make sure the company is licensed in California

Check your AC repair company for proper licensing and insurance. The California Contractors State License Board requires HVAC contractors to maintain proper licensing. HVAC technicians who handle refrigerants must be certified by the Environmental Protection Agency (EPA). AC repair professionals also need a cash bond or surety and worker’s compensation insurance.

Look for national accreditations

Some AC technicians pursue optional national accreditations from professional organizations such as the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) and the Air Conditioning Contractors of America (ACCA). While not mandatory, accreditation offers proof of the technician’s skill and expertise in the field.

Get a free estimate

Most AC repair companies provide free estimates. This involves an in-home inspection during which the AC repair pro suggests solutions and gives you a quote. Pay attention to how thorough the company is during the inspection.

Compare costs

Request detailed estimates from several AC repair companies to compare pricing. Reviewing several quotes gives you a better sense of the average price range in your area. Don’t base your decision soley on the lowest price because their work quality may be lower than others.

Assess experience

Ask the technician about their experience with your AC’s make and model. Some HVAC technicians specialize in certain types of systems, whereas others have more generalized experience.

Read reviews

Ask friends and family for AC repair company recommendations. Always look up online reviews for professionals before hiring them.

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.
