Air Conditioning FAQs

Your air conditioning system is one of the most significant – and costly – appliances you own. With so many parts and components that play a role in maintaining your family’s comfort, you’re bound to have a question or two or encounter an issue that you simply can’t solve on your own.

Read on as we answer some of the most frequently asked questions to help you become more knowledgeable about your central AC system.

How often should air filters be changed?

That depends on the type of filter you have and certain characteristics of your household. Cheaper, disposable filters will need to be changed more frequently, as often as once a month. Households with cats and dogs, smokers, or those with allergies or asthma may also want to change their filters more frequently. However, the general rule of thumb is every three months.

What are the advantages of high-efficiency filters?

High-efficiency air filters do a better job at removing dirt, dust, pollen, mold, and other pollutants from the air, resulting in cleaner, healthier air. But even the highest-efficiency filter will do little if any good if it’s clogged, so be sure to clean or change it as recommended by the manufacturer or you HVAC company.

Will a bigger air conditioning unit perform better?

Bigger is not always better. For max efficiency and optimal performance, an AC system should be sized properly for your home, its layout, the climate, along with your family’s needs and schedule. A system that’s too large will cycle on and off frequently, never fully cooling the air and leading to excess humidity. Frequent cycling also creates undue system stress and can lower its lifespan.

Why do I notice temperature fluctuations between rooms?

While a little temperature variation is normal, more dramatic temperature swings from room to room could be a sign of poorly designed ductwork, blocked registers or vents, an air filtration issue, or too little insulation in one or more areas of your home.

How long should HVAC equipment last?

Most HVAC systems last between 10 and 15 years. You can extend equipment life through annual preventive maintenance and DIY measures of your own, like keeping greenery away from your outdoor condensing unit. However, an AC system becomes less efficient as it approaches the end of its expected life and can experience more frequent breakdowns.

How often should a central air system be serviced?

It is recommended to have your AC unit serviced annually to ensure smooth and efficient operation. Annual service can also uncover problems that, if not addressed, can result in costly repairs and premature system failure.

How can I improve air quality?

According to the EPA, the air inside our homes can be up to five times more polluted than outdoor air. Annual maintenance and regular filter replacement can go a long way toward improving air quality. Check ductwork for leaks, vacuum frequently with a HEPA-equipped vacuum, remove shoes at the door, and swap chemical filled household cleaners for healthier alternatives.

How can I lower my heating and cooling costs?

  • Check and add insulation where needed
  • Seal or caulk drafty windows and doors
  • Switch to programmable thermostats
  • Consider zoned heating and cooling
  • Avoid blocking vents and registers
  • Use a ceiling fan (run it clockwise during the cooling season
