"I would highly recommend Prime Home HVAC. Our air conditioner was out for an entire weekend. I called Nathan on Monday, by Tuesday we had relief!! Nathan and his staff were professional and paid attention to detail. The price was fair and they made it easy. I love that they are a family-owned business. You will not be disappointed."

"My new HVAC system failed at beginning of summer . They worked with me to fix and resolve the problem . The last visit with their technician Hunter went well. He took the time to explain and show us the different filters that we need to monitor. Thank you Hunter , Tyler and AC techs. I canâ t live without AC. Otherwise I drip with sweat . No Florida retirement for me ."

"We were Extremely Satisfied with the Quality of Workmanship and the Product we Decided to go with for HVAC Install... At the same time we had Central Air added, we were tired of window units... Plus, it is Less Expensive to have Both Installed Together!! We Have Really Noticed a Big Difference in how the Rooms in the House are Much More Evenly Heated and How Much More the Heat is Felt while Moving from Room to Room, From Floor to Ceiling!!! The House Has Never Felt So Good!!! A 10+ Star Rating in Our View from the Install and Service from Connelly Heating Air Conditioning!!! In Addition, We Saved over $1,000. with Connelly Heating Air with Bids from 3 other Companies!!! Thank You, Jean Tony S. in Manheim, PA."

Customers say: True professional

"Woke to a chilly home stemming from a heat-pump issue. Posted my repair service need on Angi and within minutes, received a text and phone call from HOFFMAN MECHANICAL, who was able to come out same day and got my Lennox unit up and running again at a fair cost for both parts and the weekend/after hours service call fee. I would use them again without hesitation, and I am happy to highly recommend this company!"

Heating and Air Conditioning FAQs, answered by experts

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.

Condensation forms when warmer, outside air combines with cooler air in your ductwork. This can happen when there are leaks in your air ducts, your HVAC system has a dirty air filter, or there’s a lack of insulation around the ducts. To prevent it from happening, replace your HVAC filters as directed. Also, once every five years, hire a local air duct cleaner to clean and inspect them.

Yes, you should turn off your AC if it’s leaking. Turning off the system prevents more condensation from leaking and reduces strain on the unit if a damaged internal component or lack of refrigerant is the cause. While this may temporarily stop the leak, water can continue to drip from a thawing coil even after the system is off. As soon as you notice a leak, turn off the unit and investigate the source or call a professional for an inspection.

Here’s how AC professionals will clean your AC coils:

  1. Unplug the AC unit or turn off the breaker to the unit in your circuit breaker box.

  2. Remove the faceplate.

  3. Spray a vacuum hose attachment or compressed air can to remove debris, dust, dirt, and grime.

  4. Use a soft-bristled fin comb to remove stubborn caked-on debris.

  5. Use the vacuum hose to suck up any extra debris.

  6. Take a coil-safe cleaning solution and spray it onto the coils. Try to choose a no-rinse solution.

  7. Let the solution sit for at least 15 minutes.

  8. Gently wipe away loosened grime and debris with a microfiber cloth.

  9. Reattach the faceplate, plug in your AC system, or turn the breaker back on.

Unfortunately, a freon leak will persist even when your AC unit is off. The freon in the AC unit is under pressure no matter the status of the system, so it will continue to drip through the leak even when you shut off the entire unit. It will continue to leak freon until it’s completely empty.
