"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."

"I added a 14 X 18 sunroom on to my house during the middle of the pandemic. Patsy was professional and responsive. There were a couple of minor delays due to supply chain issues but Patsy was transparent about the delays and communicated frequently. The job was on budget with no surprises with regard to money. Regarding the cost of the room, my 14 X 18 room was 3,000 less than a neighbors 14 X 14 sunroom and mine was much nicer. I would definitely recommend Patsy and I would use him again for future projects."

Heating and Air Conditioning questions, answered by experts

When your AC contactor goes bad, you might hear chattering or buzzing noises coming from your air conditioner. You may also notice that your AC is running but isn’t cooling your home. In some cases, your air conditioner might not even turn on at all. There could also be physical damage, discoloration, or corrosion around the contactor.

Replacing both an AC and a furnace takes a full day on average, ranging from eight to 12 hours. The process involves removing the old units, installing the new ones, and ensuring all connections are properly made. If both systems are being replaced simultaneously, it can take longer than installing a furnace alone, so plan accordingly.

To find a reputable HVAC company, start by researching providers in your area. Look for companies with mostly positive online reviews and check the Better Business Bureau’s website for customer complaints. Next, verify their credentials. Rule out any companies that aren’t licensed, as this is a requirement in some states and municipalities, and confirm they are insured. Once you have a shortlist, contact each professional to ask key questions: How many years of experience do you have? Do you hold any third-party certifications? Do you have experience working on my specific type of HVAC system or brand? Can you provide references? What is your per-hour pricing? Do you offer maintenance contracts for ongoing savings? Do you provide a warranty for your work?

Running an air conditioner with mold is not safe because it can spread harmful mold spores throughout your home. Exposure to these spores can trigger various health problems, including respiratory issues, allergies, coughing, wheezing, sneezing, itchy eyes, and a sore throat. It may also aggravate asthma in household members. Continued exposure can increase the risk of more serious illnesses like sinus infections, pneumonia, and bronchitis. If you suspect mold in your air conditioner, you should stop using the system until it has been properly cleaned to avoid health risks and further contamination.

Yes, mini split systems cool equally as well as central air. While a central system circulates air throughout the entire home at the same temperature, a mini split system allows each room to be cooled or heated at different temperatures based on your own preferences. Hire a HVAC professional to determine which type of system is best for your home.
