"My pilot light went out on my water heater. Casey relit it and showed my how I could do it if I needed to again. I would definitely call them again if needed."

"Good.. Repaired within one hour..great job .."

"They responded quickly. Were able be out and fixed my water heater within a few hours"

"I had a water heater in need of replacement. I discovered the issue late afternoon 11/6/25. Kevin immediately put together an invoice based on pictures and my own description. He showed up this morning at 9:00 am, was very friendly and professional, and the work is done less than 24 hours later. It is now noon on 11/7/25 as I write this. The quality is up to par, and even exceeds what you see with larger base contractors. The pricing is fair and competitive, and the punctuality is solid. I would strongly recommend Kevin and company to anyone looking for quality and competitively priced work. Also the fact that he is a small local business makes it that much better. Thank you Kevin!"

"Pros: They were extremely quick to come out. They were able to start and finish the job within a couple hours. Great service overall Cons: limited on your water heater choices. And they are a little pricey. (You get what you pay for though)"

"I ended up getting a cleaning on both systems. Eddie did an excellent job. Later I needed a repair and used them again. Stephan Rardon was superb!!"

"I contacted Alexander Heating and Air to fix my water heater on Wednesday and they were scheduled to arrive on Friday. The team of two arrived on time with smiles on their faces. The heater's Pressure Reducing/Pressure Regulating Valve (PRV) valve was bad and caused my whole house water pressure to be very low. Also, I had excessive water trickling on the garage floor from the overflow pipe (due to a defective expansion tank. It’s the expansion tank’s job to take on this “extra” water caused by thermal expansion). Jeremiah, who did most of the talking explained what was going wrong with my heater, explained my options, provided an estimate, and explained that my specific water heater was about at the age that it will likely need replacing. It was good to know as I can now get my finances in order to eventually get a new one. He even explained financing options to me should I want a new heater and need financing. The two were friendly (did I mention Jeremiah is a Veteran), knowledgeable, worked quickly in the heat (they had to go under my house), and cleaned up and were finished in no time. The price charged was very reasonable, especially considering that I couldn't water the lawn properly, showers in house with low pressure was awful, water flow on garage floor would ultimately cause floor damage, and I didn't have to purchase a new water heater, yet. I really have had such good experiences with Alexander for several repairs they have made for me in the past, too My water pressure in the house is back to normal! I am more than satisfied with Jeremiah and the Alexander Heating & Air team."

"Never returned three calls after leaving message on 11/11/2013, 11/13/2013, and 11/21/2013, that we needed either a new hot water heater or tankless hot water system installed.

Update: return phone call on 11/22/2013-- see note above. This resulted in a change to my evaluation from F to C overall.

"Tim was outstanding. He called before arriving. He took a look at our system and made the necessary repairs. He also provided general maintenance to our water treatment system. Tim quickly assessed the problems and was very professional throughout the time he was here. I highly recommend this company for water treatment needs."

"Danny was very accommodating. He was a pleasure to talk with and understood that being without hot water is a problem. He was able to change some schedules and had the tankless hot water heater installed in a day. He wore his mask and the workmanship was excellent. He did not leave a mess and I would hire him again in an instant."
