Heating and Air Conditioning questions, answered by experts

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

Yes, you can run an attic fan with the AC on. In fact, you don’t have a choice with a passive attic fan. Plus, when an attic fan draws out hot air from the attic, it helps regulate the temperature of your whole home, so your AC doesn't have to work as hard.

There are likely dozens of HVAC repair companies that service your area, and choosing the right one can be a tricky process. To hire the right HVAC technician, we recommend reaching out to local companies and ask the following questions:

  • Are you licensed and insured?

  • Do you have any third-party certifications?

  • Do you often work on my specific type of HVAC system?

  • Do you provide any warranty for your work?

  • Do you offer maintenance contracts for ongoing savings?

  • How many years of experience do you have?

The length of an AC cycle depends on the settings in your thermostat and the unit you have. Central AC doesn't constantly run at full blast the way that a window unit does. A cooling cycle in most homes is 15 to 20 minutes. Then, the unit stays off for seven to 10 minutes to circulate the cold air in the house before the cycle repeats. It should repeat two or three times per hour. A short cycle lasts less than 10 minutes and then turns off.

Split systems are the most common type of HVAC system. Split systems have two main units: an indoor one and an outdoor one. These units work together to pull in air, heat or cool it, and distribute it throughout your home. Other popular types of HVAC systems include hybrid systems and packaged heating and air systems.
