"In a pinch last night and in cold weather, my newer furnace was suddenly not functional so I was forced to reach out to Doty after hours. Clayton answered my call and patiently walked me through multiple steps to correct the issue. With newborn babies in the home, the loss of heat required urgent attention and Clayton exceeded my expectations. Although this newer equipment in a newer home was installed by another local HVAC company, I knew Doty from previous experience living in the area and was confident superior service would be provided. I will certainly reach out to Doty first for future issues. Thank you again, Clayton!"

"Jonathan did me real solids today. Despite the fact that they were here to clean up bascially messes left by the installers on my HVAC on both AC and furnace, he AGAN went ABOVE and BEYOND when he noticed I was doing my own plumbing project. We had hot water seeping out with our water main shut off on a fixture exchange, and he pointed out we can drain the hot water heater partially to stop this. The last plumber didn't eve care to share this, or even do it. I will not go ANY OTHER PLACE than Service Professor for my plumbing, HVAC and electrical needs. PERIOD. No one else compares!"

Heating and Air Conditioning questions, answered by experts

An air conditioner’s watt usage depends on multiple factors, including the type of AC unit, its size, and how often you use it. With that said, most central air conditioners consume between 3,000 and 3,500 watts. Meanwhile, window AC units use 900 to 1,400 watts, and portable air conditioners consume 2,900 to 4,100 watts.

Modern AC leak sealants work as a temporary measure to stop refrigerant leaks. You can purchase them at most home improvement stores or on online. When using an AC leak sealant, keep in mind that it’s only a temporary solution, so you’ll still need to hire a pro to install a replacement part as soon as possible.

Here’s the cost formula to find out how much it’ll cost you to run a window air conditioner in your home:  Watts * (hours used) / 1,000 * (Local kWh) = daily cost of running a window unit. If you need help calculating the cost of running your window AC unit, consult an AC repair or installation pro for an accurate estimate.

No. Your furnace does not run your air conditioner. Both units use the same system of ductwork to move conditioned air throughout your home, but you can have a furnace without having an air conditioner and vice versa. Furnaces are only for heating your home. You can buy a system that does both, however, like a split system or a heat pump (yes, heat pumps cool, too).

If you’re trying to buy a new AC unit, there are a few crucial factors to consider. Look at the cooling capacity, the available warranty, the energy efficiency, and the type of unit. A ductless unit will cost more up front but may be a more viable option if you don’t already have ductwork. Additionally, a unit with better energy efficiency will cost less to run overall, saving you money on your monthly energy bill.
