Recommended Customer Reviews

The HVAC manager, Matt, called first thing this morning and went out of his way to make things right for us after 2 days of an AC leak in the ceiling. Matt fixed the issue himself! Love that E. Dennis puts their customers first! I highly recommend E. Dennis for your HVAC, electrical and plumbing needs. They are honest, dependable, and professional!

I called and ask for Donie to come out and fix my problem,he showed up done a Awesome job. I will not go anywhere else, the job he done , I will tell everyone the service I got very professional. I won't ever go anywhere else.

E. Dennis has been one of the few HVAC companies I haven't had a problem with. They have always been prompt and courteous whenever I've called them. The technicians are very professional and have even fixed problems I was unaware of.

Never use this company never. My family owns three homes they handled service for all for several years. They installed Lenox units. at some point in the last year or so they tell us that they went through a software and company philosophy change if you are a really good customer you must pay for a full year of service in advance. When they come out to do the summer service you must go ahead and pay for the fall service six or eight months later that will be done. Kind of like buying milk today But not needing it until December if you opt to use it. . they were really jerks about it. And I will never recommend them anybody I know or care about use them.

Sam Monford did a maintenance service on my HVAC unit. He was very professional and did an excellent service. Very knowledgeable and provided exceptional customer service care. Thank you Sam.

horrible experience, they charged an outrageous amount and did not fix the issue. i called a real plumber out and he fixed the problem in 20 minutes and charged me 20% of what e Dennis charged to not fix it. I gave them the chance to split the bill, cover the cost of a truck roll and pay the technician, no response whatsoeve. would not recommend .

Jeri took my call on Memorial Day. Offered a service call within an hour and a half. She was exceedingly nice on the phone. Brock replaced my capacitor, was polite as heck, resolved quickly and pricing was more than fair. I have a medical condition and being overheated is miserable for me, so I really appreciated the service when others were closed. Was not impressed with Rainwater HVAC previously, and wouldn't use them again...but E. Dennis is worthy of your business. Saved my skin today!

Last week our air conditioner stopped working and Brandon S. and his crew came out to replace our old system. Brandon was able to get our new air conditioner installed the same day and save us from the sweltering heat. We are totally impressed with Brandon and the E. Dennis employees. Brandon has checked in on us twice to make sure everything is working up to our expectations. I would highly recommend this company to any of my friends or family.

Very professional and prompt service. I called them as soon as they opened and they were able to get me an appointment on the same day. No extra fee for same day appointments either. Did i mention my Technician completed the diagnostic and fixed my air conditioning unit in less than an hour. They are great.

They were called last month to repair a water leak outside near our street meter. Initially, the plumber mis-identified the type pipe to repair. My builder needed to get involved to help him identify it properly. Once known, he let me know they didn't have the needed part, but would source it asap in order to repair the leak. The company called 3 days later to let me know they were still searching and would let me know that it would be repaired as soon as they found it. I didn't hear from them again. Ten days later with water still leaking, I texted the plumber direct to ask the status and he seemed confused and didn't reply thereafter. I found a different plumber and it was repaired within 2 days. I've since called the company 5 times asking to speak with management. A customer service agent replied once, but none of the managers has returned my call to date. Hard to believe management can be that unresponsive. Mistakes happen, but failure to rectify poor performance is really bad for business.
