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!
Repair person came out told me what needed to be done but was not ble to resolve the issue. Scheduled an appt for next day, NO SHOW NO CALL. 90 + degrees. The response to complaint was I'll have a Manger call next day!! Still no appointment, what a joke.
Frank G.HVAC UNIT IN attic was making a loud noise when it came on and off. First 2 techs couldn't locate issue and the third tech Nic came out today and after about 30 minutes located the issue and repaired it. Line from Evap Coil was vibrating when the unit came on and was banging against the housing unit. Great service on time and Nic was very professional
Chris D.I had a situation leaving my household with no water. I dug around looking for a plumbing company that said they were 24/7 open, this company claims that. This is far from the truth.
They have an after hours call center which is just about as useful as an answering machine, they can't book appointments, they cant dispatch technicians, but worst of all they will lie about this.
I called and spoke to a lady early afternoon on Sunday and she asked if I wanted to set up an appointment to which I responded with ""only if you can get a technician out today"" and she assured me this would happen and it would be a short time before I was contacted with an ETA for the technician.
2.5 hours go by and no call, so I call back and was told technicians are just busy in the field and would be a bit longer before I was contacted.
At this point I have full faith that someone will be coming by that night. Then 9:30 pm rolls around and still no call. I have waited and waited and put off the idea of just getting a hotel so that I could shower.
I call them back at 9:30 and finally get some one who is honest and tells me that no one is in the office and everyone I have been speaking to was just in an after hours call center that just puches the information they collect to the actual office with seems to only be open on weekdays from what I have learned.
They finally call back on monday morning around 8:20 am and I explain my distain with the whole situation. The lady asks if I'd like to speak to a manager like that would fix something.
Long story short, 30 minutes on youtube and a discover of the plumbing connections known as Sharkbite and the problems were all solved for under $100 including some new tools.
my sink fell disconnected from the granite called for service assured me they do this. 79.00 service call fee. Okay. Tech gets here wants to give me a new garbage disposal nothing wrong with the one I have repipe everything Been working fine for 20 plus years. 2800.00. Really I guess it's there way to get to peoples homes give them something they don't need but make 79.00. That's okay with help from a friend I got the sink back up for less than 15.00. I will DYI things from now on. Too many people not are so dishonest and are take take take no morals.
Stood up! Had an appointment between 8-12 and missed a call from tech at 11:19. I called back at 11:26 and was told the tech canceled because I didn't answer the phone?! I can't express the amount of unprofessionalism this is...have your customer waiting 4 hours only to cancel after a 6 minute missed call? I should have read the other reviews!
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.
Ryan and Chad the owner both stand behind Joshua the tech. If the New construction home is unsafe in Sept 2023 when they serviced it and let the system run until today and now it is unsafe how is that possible. They turned off the unit on a Holiday weekend. Ethical and shady practices.
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 .
Worst at plumbing!! Don't waste money on them and even got talked into hvac and canceling. Plumbing isn't a reliable option and guy wants to say if I have to put a shovel on the ground I'll have to charge you and if you want to save money call whoever works in sprinklers. I called you and fix it. I was willing to pay extra for them and was unwilling and trying to talk me out of it. What a joke, it was 1:20 and I guess he was hangry and didn't want to make money
