Heating and Air Conditioning questions, answered by experts

To keep your air conditioner in good working condition, you should have it serviced by a professional at least once per year, ideally in the spring before the cooling season begins. If your AC unit is 10 years or older, consider servicing it twice a year (once in the spring and once in the fall) to catch potential problems early and help it reach its full lifespan. During a service visit, a technician will inspect, clean, and replace parts as needed. Regular maintenance helps avoid costly repairs. As a DIY task, you can also clean the evaporator coils annually.

When your HVAC system is loud, a few different causes are possible. If you have loose connections or bolts in the hardware, they can rattle as the system runs and vibrates. If you have an extremely dirty furnace filter, it could cause the system to generate noise. More commonly, an excessively loud HVAC system indicates a malfunction in the system. You may have a blower motor that is close to failing or a compressor that is breaking down. These issues require an immediate inspection.

Most units are designed only to cool the house down to 20 degrees less than the temperature outside. This means that if it’s 99 degrees Fahrenheit out and you’re trying to cool your home down to 65 degrees, you’ll notice your AC is struggling. 

Lower the blinds on all your windows, turn on your ceiling fans, and keep the thermostat at a consistent temperature to help your AC do its job. Investing in an HVAC maintenance plan also helps because pros will come out to inspect and tune up your unit regularly, keeping it in optimal working condition.

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.

No, it isn’t necessarily bad to turn your AC on and off frequently—contrary to popular belief. Even if you stop and start your AC throughout the day, it won’t use as much energy as it would if you ran it nonstop. 

If you’re concerned about your power consumption and energy costs, there are a few simple ways to use your AC more efficiently. Regularly cleaning the filters, scheduling routine maintenance, and using a programmable thermostat are all great choices.
