Recommended Customer Reviews

Quentin and John spent 7 hours making plumbing repairs to almost everything in our house that has water running through it. They were on time, polite, thorough, and took the time to explain their work to me. I am grateful for their work.

Started off the New Year without heat...memorable start to 2019! Called on the 2nd and the person answering the phone (Rosalind) was friendly and awesome empathizing with my sadness of no heat lol Sent out Keegan to come out and fix...um this guy is AMAZING to deal with! Very friendly and knowledgeable in his work! He'll answer the twenty bazillion questions you might ask and explain everything well. Make sure you use this company and be sure to ask for Keegan as he's the best!!!

So let me tell you my experience with MM over the last fe months. It started with some faulty wiring with my old system. It was memorial day weekend, I know right, it couldn't have happened at a more inconvenient time but I digress. So I happen to come home early from a camping trip and when I got home I noticed that my circulation pump was running. Didn't think anything of it till the next day and found that not only was it still on the system was radiating a lot of heat. So I called MM and was told that one of their service people will call me back when they were on their way. Matt (owner) called me back within minutes and instead of just coming out and charging me a hefty fee, Matt did kind of a triage with me over the phone. What he was doing was trying to save me money by helping try and figure out what was going wrong and maybe fix it myself. Unfortunately we weren't able to figure out over the phone. Matt came out and was able to find the problem right away. It was a wiring problem that if left any longer could have been pretty disastrous (meaning possible fire). Fast forward a month to June and now I'm in the market for a new system (mine needed updating was 15 years old and it was a Munchkin). I attempted to get quotes from three different companies one was the company that did the original install, one was considered the top rated company on the Home Finder app and of course the third was MM. Well to cut to the chase, the first two failed to follow through with their quotes (meaning I never got them!). Once I decided to go with MM I called to set up the install date told them what I wanted and thought I was all done. Well a few minutes later I get a call from Matt and he lets me know that the water heater I chose although very good was very expensive and excessive for what my needs were and offered and alternative which would in turn save me $600! Of course I went with his recommendation. Here it is August and just had the install only took one day (sooner than projected). Matt and one of his employees were very professional and thorough. They did an outstanding job and I am very pleased with their work. I've attached some photos of the install with before and after pictures.

Dealing with the joys of owning an older home. This time it was the kitchen faucet and a mixer valve issue resulting in noisy toilets. Keegan and Robert came out and installed a fantastic new faucet and quickly addressed the mixer valve. Glad the old faucet wore out! They were on time, explained what was going on with the toilet noise, and provided two options to address the mixer valve in the future, plus an estimate. Also, called ahead to let me know when they would be at the house. Everything done in less time than I expected and the kitchen left nice and clean. Curtis is great to work with as well for annual furnace maintenance and carbon monoxide checks. Very thorough. Appreciate being able to call Mountain Mechanical for the routine and the unexpected.

I would look elsewhere. These guys don't do great work. Sort of half ass. Plus, not super responsive. Called at 8 am as soon as they opened bc no hot water. No assurance they will come out that day. They don't even call back until next day. Other outfits in town do good work, same prices and more responsive

I call them for my leaking sink, and they fix the one leak but didn't fix the other. So in short there are multiple leaks. I call them back and make another appointment and of course I had to take time off again from work. They came and said this time it's the faucet the causing the leak, and then said they don't have time to fix the leak and call them back once I have the part!!! I was like I took the time off and make an appointment with you and you're telling me you don't have time!!! What a freak!!! And he want to charge me again for labor to put the faucet in after I paid $300 just for labor not even 2 hours!!! Problem that wasn't really fix. I said that's why I called you to diagnose and fix the problem and now you will charge me again! In fact they should have caught the other leak if they tested it but they didn't it was me that noticed the next day! What a really bad service by Matt which happen to be the Vice President of the Company. I will not call them again. Never again!!! Really bad service!!

Very responsive got an appt right away. Two knowledgeable and capable guys came out and installed 4 toilets. Very pleasant. Would have given 5 stars, but they left black hand prints on quite a few walls and door frames....

Had Keegan out for an estimate and he was awesome and knowledgable, but I cannot get anyone to call me back to get the work done over a week later. If I get the work finished, I will update this, but for the time being, don't be in a rush with these guys.

I had an excellent experience with Mountain Mechanical. Being a new homeowner, I am still getting familiar with all of the strange noises my condo makes. I decided to take a bath and started hear this scary hissing sound, like something was catching on fire. So I go and investigate the closet where the sound is coming from and it appears to be the water heater. When I bend down to look at it, the front panel is halfway off, giving me a glimpse of glowing orange flames. I immediately freaked out and called Mountain Mechanical. A very friendly guy came and checked it out, then explained that I had used up all the hot water and the hissing sound was cold condensation dripping onto the heater. The glowing orange flames, which are normally blue, were leaping around with the hissing because the drops of condensation would momentarily interfere with them. No safety issue. Seeing how shook up I was, he stayed and had me turn on the heater, listen to the sounds, and then explained those too. He even prepared me for ticking sounds from the baseboards in the winter. I will be calling them again to schedule an inspection, and will keep their number handy.

This place is ripped me off!!! YOUV'E BEEN WARNED-CAUTION-STAY AWAY- YOUV'E BEEN WARNED- They Charged $170 to replace a Sweat valve, it was leaking the next day, called so they came out following day and resoldered. I figured they got it right so went on about my business, later finding out same valve was leaking again and turned green,blue from the leak. Called to let them know and it seemed like they didn't give a shit. Bad Reputation is right! DO NOT USE these guys and if you do, don't say you weren't warned. They owe me $170.00 for an incomplete and shady job or a satisfied replacement of a sweat valve and soldering. YOUV'E BEEN WARNED-CAUTION-STAY AWAY- YOUV'E BEEN WARNED
