San Diego is no stranger to airborne aggravates. It was recently ranked the nation's sixth smoggiest city, and its native pollen can aggravate allergies, asthma and other health conditions. A reliable HVAC (heating, ventilation and air conditioning) system with air filters can help alleviate symptoms. With San Diego County's warm climates, a reliable air conditioning system also brings relief from hot weather. Heating is also essential for San Diego's mountain communities where snow and freezing temperatures occur.

AC repair San Diego tips

Save energy in San Diego

To save energy in San Diego, consider installing Energy Star heating and cooling systems. Make sure your air filters are changed regularly to keep equipment running efficiently. Close blinds and curtains during the hottest part of the day to keep temperatures lower and reduce the amount of energy it takes to cool your home. A programmable thermostat can help ensure the system isn’t on when it’s not needed. HVAC professionals recommend sealing and insulating ducts to keep cool air from leaking into attics or crawl spaces.

Types of AC systems in San Diego

  • A window air conditioner is a stand-alone unit that mounts on a window frame. Not ideal for larger homes, a window unit is efficient for cooling a small room. It functions by pushing warm air out and cooling air as it comes in.
  • A central air conditioning unit is designed to cool a whole home. Its capacity is based on home size. Using ducts installed throughout the house, the central unit circulates cooled air. In San Diego, the central air conditioner compressor is typically installed outside the home.
  • Portable air conditioners force warm air out of the room through an exhaust hose in the window, returning cool air. You can move the unit around the home as needed. Installation is easy and flexible.
  • HVAC systems combine heating and cooling elements into one system, using vents and ducts to circulate air throughout the home. Best for larger homes, the system typically consists of a furnace inside and an air conditioning unit outside. HVAC systems require professional installation and are an investment in a home’s value.
  • Evaporative air conditioners cool the home using only air and water, not freon or other refrigerants. They function by drawing warm air over moistened pads, cooling and distributing it throughout the home. Also called “swamp coolers,” evaporative air conditioners work well in hot, dry climates like San Diego and are affordable and efficient.

What should I look for in central AC?

When shopping for central AC, look for Energy Star rated systems that operate to specific efficiency standards and can help save money on utility bills. A SEER rating also indicates energy efficiency: the higher the SEER number, the higher the efficiency. Also consider brand reputation and warranty, along with expected lifespan of the unit.

Air conditioning San Diego FAQ

Should I get an HVAC tune-up?
An HVAC tune-up is an essential part of maintaining your home, so we highly recommend you discuss it with your service provider. Air conditioning and heating systems function more efficiently when filters and coils are clean, helping save money on energy bills. A tune-up can help identify worn components, preventing significant repairs down the line and extending the life of your system.
What are some other ways to cool down in the San Diego heat?
It's essential to avoid overheating during the summer. If you are having your HVAC serviced or repaired, you have a few options to stay frosty. Of course, staying home with the AC on during the hottest part of the day is preferable. San Diego's beaches provide a great way to cool down on hot days, and there are freshwater splash fountains at the free Waterfront Park downtown. Go museum-hopping in Balboa Park - Fleet Science Center, Museum of Man and other park facilities have air conditioning.
What are the pros and cons of window AC units?
Window AC units are generally inexpensive, easy to install and preferable for renters as many San Diego landlords do not invest in central HVAC systems. For small spaces, window AC units work well, but for large homes, it is incredibly inefficient. Window AC units can be cumbersome - make sure the window frame is strong enough to support the extra weight. Once they install the unit, natural light and the ability to open and close the window is blocked. Window AC units might also make your home more vulnerable to intruders who can rip it out and use the window as a point of entry.
What are the benefits of an AC tuneup?
Getting an AC tune-up can benefit homeowners in San Diego where air conditioning is running in many homes most of the time during summer. Technicians can catch minor problems to prevent them from becoming significant repairs. They can also change filters or clean components to keep up the system's energy efficiency. Plus, manufacturer warranties on new AC systems require owners to have a professional tune-up once a year for the warranty to be valid.
How can I keep the air in my home clean?
While San Diego's air is among the nation's most polluted, you can make improvements to your home's indoor air quality. Indoor plants convert carbon dioxide into oxygen. Regularly changing the air filters in your home's HVAC system helps capture allergens and particulates. Some HVAC systems use UV-light purification that kills mold and bacteria. Remember: Vacuuming and cleaning carpets where debris from the air settles can improve indoor air quality.
