"The service was perfect and wonderful."

"Removed old hot water tank and replaced it with a tankless hot water heater. Work was done in crawl space with less than six feet height available in work area. All done in a few hours last September. It's now the following August (11 months or so later). Everything seems to be working okay. Workmen were polite, professional, timely, focused on the job, carried away all the old parts and cleaned up well---we were quite pleased with the whole process."

"Everyone from Delta Heating & Cooling were highly professional and courteous. Everything was done as quoted. Michael, the sales rep came back during the install to make sure everything was going smoothly and afterwards to answer any questions. Kelley at the office was very nice and responded quickly to my requests. I would recommend Delta to anyone looking to have their HVAC system replaced."

"Chris Cash and his assistant Hunter replaced my underground water service line on 10/27/25. Both were a pleasure to work with and I wouldn’t hesitate to recommend them both for all of your plumbing needs. Chris knows how to take care of his customers and exceeded my expectations again & again!"

"Very professional, explained things as they went along, even came back in two days to help me re-light the pilot light on my new gas water heater so I would know what to do."

"Everyone was really great, they gave me a quote and were out the next day to replace my hot water heater The guys were the best and it didn’t take long, would highly recommend"

"Highly recommend excellent service and on time."

"Good work replacing furnace, hvac and ductwork. Did not complete job in the time frame promised, but did bring heaters over and provide a gift card to a steakhouse for the inconvenience. I have found them difficult to reach to schedule included service that was included with my purchase."

"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."

"They gave great advice on where to install the new tankless water heater and worked hard to get it completed. Would highly recommend the contractor."
