Textbook how it should be—very happy with Justin and the team at Alexander’s.

Justin was extremely professional and did a fantastic job replacing some parts on my furnace

I had a heat pump installed by Alexander's. By far, the biggest reason the project succeeded was Justin Lanier. Due to some misinformation from Bryant (the manufacturer), the system did not work as desired initially. Justin returned to my house twice to make sure the system got set up the right way and worked well. Having now had the inspections completed too, I can also mention that the inspectors were complimentary about the quality of the installation done by Alexander's.

For the first time, we hired Alexander back in February, 2017. We just bought our house and water heater died 2 months after. Our friends suggested to call Alexander as he did some work for them and they were happy. Alexander was able to be at our house the next day, it was very important for us since it was February. Second time we contacted Alexander half a year after when we wanted to replace our old furnace. I wanted to install 96% efficiency furnace and Alexander had no problems with installing it. I wanted to install A/C next spring and asked Alexander about estimate. I was really surprised that he kept his estimate when I contacted him 7 months later. His guys were able to connect A/C to our Ecobee without using additional wires. Some time after this we decided to renovate our kitchen, our old kitchen didn't support proper range hood installation so we needed someone to do a duct work for us, I immediately contacted Alexander. His guy did all work perfectly but the biggest surprise awaited me later - Alexander didn't take any money for this work! I highly recommend this company - great service and very fair prices.

Easy to schedule our heat pump maintenance. The technician was on time, worked quickly and was friendly. Highly recommend this company.

Mark was very professional as well as knowledgeable! He is the first technician I have worked with to take the time to thoroughly diagnose and identify the issue with my furnace! The part was ordered and he installed a loaner until it arrives just so I would not be without heat!! Also, the price was very fair. I highly recommend this company!

Hired Alex to replace my furnace and water heater and move both into a new location. His crew did a great job and were polite. They finished the work that was scheduled for 3 days in 2.5 days. Alex gave me the cheapest quote and didn't think much about the execution plan of how he is going to move the furnace and water heater into new place. He just figure it how to do it quickly.

Mark was helpful and friendly. He explained in detail of his work. Its very helpful for someone like me to have a better understanding of what he was working on. If I ever need any help in the future, I would definitely request Mark.

Alexander’s installed Bryant 3 zone heat pump system works great, is economical and keeps us comfy year round. Top notch people!

I am so glad that I came across Alexander Heating. When my water heater leaked, I contacted 3 other vendors first; everyone gave me a bit of a run around, and the quote offered for upgrading to a tankless water heater was just jaw dropping and unrealistic...
Then I found and reached out to Alexander Heating... Dean was just amazing to work with! He was punctual with his appointment, knowledgeable, gave me no nonsense options, and offered an honest pricing for going tankless that I would be foolish to turn down! I essentially signed the contract on the spot! Plus, the work was done within 48 hours; the technicians updated me in great details on the works involved, options for ducting, did a quality job and left no trash behind! I am super impressed!
I am so happy with Alexander Heating that I am switching my annual HVAC service contract to them, and will be working with Dean next year in replacing the 2 aged fireplaces during my upcoming renovation project!

I worked with Dean to find just the right heat pump / AC system for our house and he did extra research to make sure we got the right equipment. The installation went well and it performs as we hoped! It took the team some extra time to program the system so that it would run on the right 'stage' but their team was courteous in listening to my concerns, and they worked hard to get it resolved. Alexander's is a good value and I liked their friendly team.

Justin arrived timely and diagnosed the needed repairs quickly. I would highly recommend Alexander’s Heating.

Justin was great, provided solutions for all my concerns. Very helpful and patient. Spoke in terms I could understand.

Scott Lane from Alexander’s Heating & Air Conditioning came it to troubleshoot a condensation issue. Scott was able to identify the problem and made an adjustment to the PVC drainage at the bottom of the unit and added an extra water monitoring piece for extra precaution. He was excellent to work with and very polite. We would highly recommend Alexander’s Heating and Air Conditioning.

⭐⭐⭐⭐⭐ Exceptional Service and Expertise!

I have had very positive experiences using Alexander's Heating & AC for maintenance and services of my HVAC for years. I have a combo gas furnace and electric heat pump system. The previous owners of my home installed the system using Alexander's. Since then, I have continues using them for annual maintenance and repairs. Every time they are prompt, response, helpful, and competitively priced. I have had the same service tech (Mark) for multiple years and he has been great. Very respectful, friendly, and knowledgeable. Would highly recommend working with them.

Highly recommend. Simple, no noise quote, pro sales and installation experience. Check Akexander's BEFORE you buy.

My Furnace Fan motor broke down going into the hottest day of 2025. Scott Lane was able to come out within 24 hours and get the issue fixed so that our AC was functional for the 95 degree day. Scott is actually a manager but was willing to go out into the field to help people and I can't tell you how appreciative I am for that. Alexander's has been fantastic to work with in the past and I would recommend them for anything going forward.
