Heating and Air Conditioning questions, answered by experts

Vents may blow air even though the air conditioning system is off because of the pressure difference between indoor and outdoor air or drafts from leaky ducts. Check for leaks or drafts in the ductwork or around windows and doors.

While both have advantages, a split system is generally cheaper than a ducted one. Because they are less invasive to install, the labor costs are lower, and they can be more energy efficient. But, a ducted system might be worth the investment if you run it more frequently. 

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.

A frosty expansion valve that isn't blowing out cool air is a sure sign that it’s time to replace it. It might also be time to replace the TXV valve if your AC unit switches off soon after turning on or if you have poor airflow in your home.

There are ways to detect a refrigerant leak with several different testing methods. However, most homeowners can figure out something’s wrong with their AC unit by noticing these common signs:

  • Ice forming on the evaporator coil

  • Water leaks near the AC unit

  • Frequent hissing sounds

  • Increased electric bills

  • Unit takes longer than usual to cool

  • Unit is blowing hot air
