First appointment scheduled scheduled between 8-12pm. No show and then a cancellation around 1:30. Asked to reschedule the next day... at 3:10 i get a message from Ken that they need a confirmation to come. Very unprofessional as he left me a message saying the following: Transcription """"Good morning this is Ken with the Dennis AC plumbing electrical trying to reach Mr. William answer hey I'm just giving you a call for an update ETA for your appointment today it looks like you are next in line am we are looking at an arrival time though between 1230 and 230 for your appointment if you have any questions or concerns please give us a call at 678-403-1071 thank you have a good day...""""

Had a Freon leak- Luckily, a tech was able to get out to our home same day but we were charged $139 for an """"After Hours"""" fee because he was coming after 5PM. Checked the line-set coming from the unit, said it was leaking and offered up a $100 dye test through the system to see where it was leaking.. Couldn't really afford that extra seeing as though it was already well over $500 to have the tech add freon at over $100 per pound. I realize the cost of living has gone up but DAMN!! I asked the tech why 410a costs so much, he replies with """"Well, I can stop now and you can just pay me what I put in"""".. SIR! Not an answer. I realize it was 6PM and I am sure dinner was waiting but seriously?? It took 30 minutes for him to LOOK, Add Freon, and take my money... Freon leaked out within a day. Had another tech come out. Pulled out a handheld device, took 5 minutes, and found the leak. Fixed the leak and charged the system back up.. less that what I paid this company. Would not recommend unless you are in a pinch... or just desperate!

My A/c was not cooling so I called this company, Paid service fees and was told my unit needed to be replaced. The tech claimed there was a leak in the system and according to him, there was a serious leak """" his tool was going crazy"""". The quote for a new system was over $3,000 for the least expensive option. Thank goodness, i said no and told him I wanted a second opinion before spending that type of money. Another company came out and found no leak in my system. The repair was made at a fraction of the cost and my home has been cool since. I called the company to inform the company of a possible bad tech, never received a called back so I assume it was not the tech, but the culture at the company. I would not recommend this company and if you do get an estimate get a second opinion before saying yes.

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.

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.

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!

They sent out a tech, Josh, to our home to replace a thermostat that quit working. Josh did a wonderful job replacing the bad unit with a different new unit and he took the time to go through the operation and features with my daughter. He was 100 percent great!

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.

I'm a first time home owner and this was my first time having an issue with my AC unit. Saturday night I turned my AC on because it was 85 degrees in the house. I left my house and came back 2 hours later and it was still 85 degrees. I thought maybe it was my Nest causing the issue so I waited until Sunday to test again and had the same issue. I went outside and checked the AC unit and the fans wasn't moving. It was 91 degrees outside and 86 degrees inside and I knew I needed service. With this being a holiday weekend, I just knew I would have to be in my house without AC for a least 2-3 days. I called around and everyone had an outrage fee just to have someone come out to look at the unit on a """"holiday"""" Sunday. With a quick search I found E Dennis AC and gave them a call. Within 40 minutes, Brock was at my door ready to work. Less than an hour Brock had my AC back up and running. This has been amazing service. Brock educated me on what was causing the issue, he gave me a price break down, and what he had to do to resolve it. I'm now relaxing with my AC colder than a polar bear toe nail. They have a customer for life with me!
