"Had a complete HVAC system replacement. Through the whole process, they did what they said they would do and within the time frame that I was told. They responded timely and answered all my questions and concerns along the way. I am an impressed customer and delighted to recommend Major League HVAC."

"I am a new homeowner and the broken water heater was my first major repair. After getting the run around from my home warranty company (AHS), I took matters into my own hands and went to the Angi app. I received a personal phone call within minutes of submitting request on a Friday and Done Right came out on a Saturday. Ryan was a professional, warm, and courteous contractor. He followed COVID protocols and had the new heater installed on Monday. Could not have been a better experience."

"Patsy Cicala has so much knowledge and experience and was able to dismantle the mess made by the plumbers and correctly configure and install the filter system. It is working perfectly now and we are enjoying pure filtered water. Mr. Cicala really saved the day! In addition to being experienced and competent, he is reliable, respectful and pleasant to work with. I definitely recommend him and will contact him again for any projects or services needed in the future."

Heating and Air Conditioning questions, answered by experts

You should flush your AC drain line once every three months to keep it clear of debris and buildup. Keeping your AC drain line clean prevents clogs, backups, mold growth, and extra wear on your AC unit. If you live in a humid area or have several furry pets, up your cleaning schedule to once a month.

While your AC unit may still run even if its capacitor is going bad, doing so takes a lot more energy, so it can drive up your electric bill and cause further damage to your AC unit’s parts. If you suspect a bad capacitor, it’s important to have a professional diagnose and fix the problem before you continue to run your AC.

The standard rule for return duct sizing is that the return vent should be the same size or larger than the supply vent. This will ensure balanced airflow in your home and reduce strain on your HVAC system.

No, a furnace is not the same thing as an AC, or air conditioner, but these are both parts of an HVAC system. They both use air ducts to transport cool or hot air around your home to achieve a comfortable temperature set by your thermostat. An AC runs on electricity, while a furnace can use different fuel sources.

For the most part, you should leave your AC fan in “auto” mode so that it only runs during a heating or cooling cycle. Keeping it in this position uses less energy, which equals lower utility bills. However, there are some situations where it’s better to leave your AC fan on, including if you have allergies or there are lots of people in your home.
