Hector came to check my furnace. When outside he could smell a bit of gas. He said he couldn’t locate the leak. He advised me to call Spire. I did and responded that night. The next day Spire crew located the underground leak and repaired the pipe. Thanks to Hector for his thoroughness and looking out for our safety.

Professional, reliable, family owned. Al-Don is an absolute delight to work with. Whether it be HVAC maintenance, repair, or replacement, I HIGHLY recommend these guys. The best HVAC company in the St. Louis area!

Al-Don literally saved my family’s lives!! When receiving our yearly furnace maintenance, the technician noticed heat coming out of a wrong spot. I had mentioned we had received a new roof over the summer. They climbed up on our roof and realized the heat wasn’t getting out at all and carbon monoxide was filling our basement when our furnace had been on! They fixed the problem left from the roofers and we are all safe!

We have used Al-Don for a couple years now and have never had an issue, all the technicians have been great and knowledgeable and always answered all our questions! Thank you Al-Don!

I had a heating issue with the cold- the entire Aldon team was awesome . They were very responsive, knowledgeable, respectful. Bottom line was the entire unit had to be replaced. Install team of 4 went above & beyond to make sure the unit was working! I cannot give enough accolades to ALL of them they went beyond expectations even though ive used Aldon for 40 years & cannot express my gratitude enough. The best! I’ve referred them to every one i know. The BEST! Call them! Highly recommend!

We called Al-Don on the recommendation of a family member and we were not disappointed! They were incredibly helpful and easy to work with. One of the parts we needed was ordered and they were able to locate a temporary part so that we stayed warm during brutally cold days. Lisa, Ryan and Hector were all efficient, helpful, kind, and considerate. Would highly recommend this company for any future heating or cooling needs!

I called the after hour’s emergency number. I had never used them before. I had no A/C on the hottest day of the year. Within 3 hours they were out, diagnosed and fixed. The technician, Alex, was polite, knowledgeable and professional. Highly recommend!

I have Jeff and his technicians do the service on my house and my daughter’s house and we are always completely satisfied. I really enjoy the yearly service contract. That way I don’t have to mess with stuff.

Hector showed up on time. He was very courteous, professional. Diagnosed the problem and fixed it in a timely manner! Strongly recommend AL-DON for all your heating and cooling needs.

On the Saturday after Thanksgiving, my 84 year old Mother called to say her furnace was not working. Within 2 hours of my initial call, a service technician was in her home and able to fix the problem. Jerry did a great job! Thanks Al-Don!!!!

Wanted to give a shout out to Leslie, the dispatcher, who does an outstanding job! Always courteous and patient.
Thank you Leslie!

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.
