Air Conditioning FAQs
How often should I service my air conditioner?
Both ACCA, the governing board for HVAC in North America, and most of the manufacturers recommend checking each mode of the system a minimum of one time per year.
Does my heater / furnace need to be checked before I use it?
For safety reasons, efficiency, and proper operation heaters, heat pumps and furnaces should definitely be checked prior to seasonal usage.
How often should I change my air filter?
Every application is different. Air filters should be changed as often as necessary to help with indoor air quality, system performance, operational costs, and overall health of the equipment and home. Never assume a filter will last exactly what it says on the side of the filter. Arizona is the exception, not the rule of thumb on this.
What type of air filter should I use?
Every application is different. Most duct systems are improperly sized, but every application should have the best filter for air quality it can without suffocating the system. Having a technician out to take measurements of the duct work is step one. He/she can make recommendations based on what we can learn about the system/duct work.
What temperature should I set my thermostat at?
Wherever you are comfortable, but within the balance of operational cost vs. budget. Keeping the system maintained will help keep those operational costs down and help the system keep you comfortable more efficiently!
