Air Conditioning FAQs

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!

What are advantages of a programmable thermostat?
Having a programmable thermostat allows homeowners to set the systems run times around the higher rates of the on-peak hours from the utility companies or when they are going to be away from home for several hours. This helps people save money on the operational cost of the system and will usually pay for itself over time if utilized properly.
Why is my air conditioner so loud?
Operational noise can be the result of the SEER rating of the system, but can also increase overtime if not properly maintained regularly or from normal wear based on usage. Maintenance can help quiet noisier systems. If that isn’t enough for your backyard paradise, a new inverter system with much quieter operation could be just what you need.
How long should my air conditioner last?
Typically, a well-maintained system can last 10-15 years before you encounter a large repair. At this point it would be wise to consider your options. A new air conditioner & heating system can you save energy which will reduce your electric bill and increase the comfort in your home.
