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.
