Don’t let avoidable HVAC issues ruin your summer. Here are answers to common AC questions that will help you keep your home at the perfect temperature all summer long.

Q: How often should I change my AC’s filter?
A: Once a month is ideal for most people. However, pet owners, large families, and people with allergies may want to change their filters every two or three weeks.

Q: Which filter is best?
A: Check the manufacturer’s specifications to make sure the new filter is the right size and type for the unit. The EPA recommends using filters with a minimum MERV 8 rating to keep your air free of dust, dander, and other pollutants.

Q: What do I do if my AC won’t turn on or stops blowing cold air?
A: Check the thermostat settings and then the batteries. Make sure your system hasn’t tripped a breaker. Change the filter, as some units won’t run if the filter is too dirty. If your unit still won’t turn on or blow cool air, call an AC repair technician.

Q: Why does my air conditioner drip water?
A: AC units normally drip water, as condensation causes water vapor to collect on cool services. However, if you notice excessive dripping or dripping in unusual places, something is wrong. You’ll likely want to call an HVAC technician to remedy the problem.

Q: Should I cover my unit in the winter?
A: You don’t need to cover your AC unit in winter. However, you should regularly clear debris from around the unit to prevent problems.

Q: What maintenance needs to be done to my AC system?
A: Professional HVAC maintenance includes checking the AC, lubricating moving parts, examining ducts for leaks, and repairing any leaks that are found. It also involves cleaning certain parts of the unit and clearing debris around the compressor.

Q: How often does my AC need to be serviced?
A: Your HVAC unit should be serviced once a year.

Q: What does ductless AC mean?
A: Ductless AC systems use multiple indoor units connected to a single outdoor unit to cool each room in a home or business. Because they don’t require ducts, they’re often more energy-efficient than regular units.
