Heating and Air Conditioning questions, answered by experts

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.

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 American Society of Heating, Refrigerating, and Air-Conditioning Engineers, or ASHRAE, sets the standard guidelines for air changes per hour in homes and businesses. The International Residential Code, or IRC, also sets ACH requirements for residences and bases those requirements off of ASHRAE standards plus climate specifics related to your location.

While you’ll pay more upfront for a brand-new HVAC unit, you can save money in the long run. Here’s how to save on your new HVAC system:

  • When purchasing a high-efficiency system, your energy bills will be lower in the future.

  • You may be eligible for special offers from your local energy company.

  • Depending on the system, you may be eligible for HVAC rebates and tax credits.

  • Choose to replace your air conditioning unit and furnace simultaneously to save on labor and installation costs. 

Definitely. Both experts and homeowners can attest to the convenience and efficiency of HVAC zoning. Not only does it make every room the perfect temperature—no matter what the temperature is for you—but it also saves energy (and therefore money) in the process. It is a costly up-front investment, but many homeowners agree that it’s worthwhile in the long run, especially if you plan to stay in your home for a while.
