Hector has always provided the most “top shelf” service. We started using AL-DON over 20 years ago and have never been disappointed! Hector is an excellent service technician, is honest, and is always providing the right information to make the customer comfortable with the decision(s) we have to make! Kudos to your team!

Ryan from Al-Don came out to service our furnace on November 3rd, to get it ready for the upcoming heating season. He did a thorough exam and cleaning of the furnace, humidifier and the fue. He let us know that the blower motor may need to be replaced at some point, but did not feel it was necessary at this time. He gave us an idea on the costs of replacing the blower when the time came. We never felt like there was any pressure that it had to be done right away. He also gave us suggestions on how to save money on our heating bill. We were very happy with this service call. It was a pleasure meeting Ryan, and hope he is available the next time we need service.
Thank you.

My wife and I recently bought a house that supposedly had new Goodman AC unit installed in February 2022. AC unit broke down Tuesday, August 2. Al-Don Tech Alex was able to come out that day after my other HVAC company I use could not send a technician. Alex was able to diagnose that the compressor went bad due to faulty installation. Alex was able to convince Goodman to replace the entire unit instead of replacing the compressor due to back order shortages on compressors. This news was received on Wednesday, August 3. Al-Don Technician (unsure if it was Ed, Jeff or Skyler) came out to replace the bad unit with the new unit. It was then determined that the copper lines and evaporator coil were damaged to to freon leakage turning acidic. Long story short, the new unit was installed, new lines and evaporator coil along with a new circuit for the breaker was also installed. A one man job turned into a 3 man job, but in the end I now have working air conditioning during the hottest month of the year along with information needed to attempt restitution was original installer. Plus your operator Leslie is top notch and was very helpful and understanding. Highly recommend to anyone, especially in an AC emergency, to give these guys a call.

“This was an emergency call on a weekend. Water was leaking from my condo to the condo below and I thought it was an AC problem. Al Don had a tech out here in 90 minutes. Alex diagnosed the problem (it was a drain clog) and did an excellent emergency repair explaining everything. He was fantastic. Have used Al Don for 8 years for my HVAC work. This was my first emergency call and they were fantastic as always!”

Hector was able to get to my house, diagnose and get the AC up and running by 7:30. Returning to a warm house after an evening outdoors on a very warm night would have been miserable!”

I was very pleased with the installation of the new air-conditioner, furnace and water heater. Tough job in a very small closet on the second floor. The installers were very professional and polite. They worked together to solve every issue along the way (and there were several) and left no mess behind. My sincere thanks for a job well done from the receptionist who set up the appointments to the installers. I will definitely recommend your company if asked for a referral.”
