Air Conditioning FAQs, answered by experts

The cost of annual maintenance depends on the type of HVAC system you have. AC service typically costs an average of $200 but ranges from $100 to $550. If your system needs repairs, the price will vary significantly depending on what needs fixing. However, addressing the issues as they arise can prevent further damage to your unit and keep it operating efficiently for much longer.

A home AC unit provides anywhere from one-half to five tons of cooling and requires approximately two to four pounds of refrigerant per ton of cooling. At approximately five to 10 minutes to fill one pound of refrigerant, a home that requires three tons of cooling will take about six to 12 pounds of refrigerant and approximately 30 minutes to two hours to completely recharge the unit.

The standard HVAC warranty is around five years. Still, many brands offer an extension to 10 years if you register the product within a specific timeframe, typically 60 to 90 days post-purchase or HVAC installation. Over the past decade, warranty periods have substantially increased, shifting from 3-5 years in the 90s to the now-prevalent 10+ year warranties. Both warranty types cover parts failing due to manufacturer defects, incurring no additional costs. Some manufacturers provide extended warranties surpassing the usual 15- to 20-year window, though these often involve extra fees. 

While personal preferences widely vary, sleep experts say the best temperature for sleeping is between 60 and 67 degrees Fahrenheit rather than 78. If you do choose to sleep with your AC unit tuned to 78 degrees, you might want to use only a sheet or light blanket rather than a comforter. You might also consider installing a window unit in your bedroom so that you can be cooler in bed without wasting energy cooling the whole house.

Yes. In fact, not only are AC tuneups worth it, but they’re actually necessary to keep your air conditioner in good condition, improve its efficiency, and potentially prevent major damage. Experts recommend getting a tuneup at least once per year. In most cases, you’ll want to schedule it during the spring so that you can address any issues before the hottest months of the year.
