"If you want it done right... build it right! Jason and John are great at HVAC, Plumbing, Electrical, basically everything that a 90 year house needs. I have already started recommending them to friends and co-workers. We interviewed 3 different contractors and went through a home warranty recommended contractor before we took the buy out from the insurance company and we picked Built Right. We wanted them to do the work as soon as we had our first consultation because they paid attention to the details of our house better than any of the 4 other professionals that looked at our house. After our first project, we have no issues on our installation and Jason really is committed to making sure we know how to maintain it. We already signed them up for a plumbing project and a small electrical project. 12/10 would do it again."

Heating and Air Conditioning questions, answered by experts

On a summer day, expect your AC to run between 12 and 16 hours. However, this time frame depends on just how hot it is outside and the comfortable temperature you’re hoping to maintain indoors. Assuming the size of your AC is appropriate for the space you’re trying to cool, it shouldn’t be a problem for it to work this many hours.

There are several tell-tale signs that your AC coils need cleaning, including:

  • You’re getting higher electricity bills.

  • Your home doesn’t feel as cool as it usually does.

  • Your AC unit is running longer than usual to cool your home.

  • Your home is more humid than usual.

  • The coil is covered in frost while running.

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. 

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.

Yes, a dehumidifier and air conditioner can be used simultaneously in a home. A dehumidifier can bolster an air conditioner’s efficiency. Typically, a dehumidifier is used when the air conditioner alone cannot keep a home’s humidity levels at a comfortable indoor humidity level, which should, ideally, be between 30% and 50%.
