"Received prompt call after setup on Angi. Wagner HVAC did service call on AC unit had issue with fan motor not turning on. TEMP WAS 90 degrees plus in house. Diagnosed that fan motor ok. Found issue with new thermostat that was not wired correctly. Checked compressor for faults. Other providers actually quoted replacement. The price for the service call saved me thousands. I would highly recommend WAGNER HVAC AND REFRIGERATION LLC to everyone. I intend to purchase maintenance plan with them also."

Heating and Air Conditioning questions, answered by experts

Most units are designed only to cool the house down to 20 degrees less than the temperature outside. This means that if it’s 99 degrees Fahrenheit out and you’re trying to cool your home down to 65 degrees, you’ll notice your AC is struggling. 

Lower the blinds on all your windows, turn on your ceiling fans, and keep the thermostat at a consistent temperature to help your AC do its job. Investing in an HVAC maintenance plan also helps because pros will come out to inspect and tune up your unit regularly, keeping it in optimal working condition.

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.

A blocked return air vent can cause your HVAC system to work much harder and, therefore, less efficiently. The result is higher utility bills and poorer air quality. A blocked return air vent can also cause unpleasant dust, dander, and odors to linger in your home’s air.

The best way to reduce heat upstairs is to release it by opening a window. Hot air rises, and if you can create some airflow by opening a window upstairs and also one on a lower level, the hot air should be pushed out of the home. Remember that fans pointing out the window do a much better job of circulating air than fans pointing into the home.

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.
