Marky Mark's Heating, Cooling & Plumbing Thornton - Thornton, Colorado

If you are looking for an HVAC company, you've found it! From start to finish Marcus and his team were easy to work with and they provided the best possible service. We replaced our 20 year old system and we are so glad that we found Marky Mark's. The price was fair and the team provided everything they said they would. Everything was installed, tested and delivered within a few hours, and it's working great. There was not a spec of mess left after the job which is appreciated. I ask a lot of questions, and the team gave me straight up answers and set realistic expectations, and delivered service above my expectations. I did my research before we made the purchase, maybe this will save you some time. This was a big decision for us and we are glad that we went with Marcus and his team!

They came out 2 times and they still didn’t fix the my Ac. I had a different contractor come. They cleaned out the coils that was said was already done. They cleaned out the condensation drain that when full it shuts off the entire system. Which is what it did. They dialed back the blower speed to within company specs. MM made me think I needed the new blower. Then after explaining all this MM made excuses to everything I just explained and still didn’t admit to not fixing the AC. Lack of integrity and ownership is baffling.

I tried calling this company yesterday for a copper pipe leak fix (shark bite is leaking just needed to be replaced) and diagnostic for a backyard possible leakage somewhere. I was told to get a call to schedule an appointment. Apparently this is not an enough job for them to do since they didn’t even bother to call me. Today I called back to see if they are gonna come out. He told me to call a Sprinkler System company for some sort of back flow and they are booked 3 weeks out. Then why not tell me this on the first call? Very unprofessional.

Adding update since the business responded. I didn’t call about the sprinkler system, I called about the line that goes to the sprinkler system vacuum has a leak from the shark bite joint. It says plumbing in the title, and looking for a leak in the backyard + fixing a copper pipe leak should be in the definition of Plumbing.

Ethan, Ryan, and Brad were fantastic to work with. Very professional and personable. They were obviously very experienced in their work and took the time to talk me through their work. Great experience and very reasonably priced compared to the previous quote from a larger company that I did not feel were as trustworthy in their inspection.

Update: On 8/26/24 Ethan came back out as the unit has frozen over. While he wasn’t able to find any obvious problems, he was extremely thorough in trying to find the issue and took a substantial amount of time looking. He did find a plumbing issue involving our furnace and the Sewer line that could have been deadly. Thanks again Ethan.

I contacted Marcus on Friday for a furnacereplacement, he was able to send his tech Ethan over for an estimate on Monday. He was able to get his tech scheduled for today, not only was this process quick it was affordable. I will definitely be recommending them to everyone but I will also be using them again for future projects.

Marky Marks HVAC and team are top notch. I've needed to use them a few times the last two years due to various things popping up but always know I'm in great hands when they do the work. Mark and his team genuinely care about the customer in how they provide options, explain various paths forward, help field questions, and overall make the entire repair process seamless. Great communication and competitive rates, I highly recommend them. Shout out to Ethan for his continuous support and help!

We needed a new water heater so I called Marky Mark’s. I was quoted a price over the phone and it was comparable to other quotes. Ethan and Mike R came out in 2 days to do the work. They were very friendly and professional. The next day I noticed a water leak coming from the hot water line on the tank. I called and Mike R arrived in about an hour. The leak was coming from a section of pipe above where they replaced the hose to the tank. Mike R fixed the leak and didn’t charge an additional fee. I am very satisfied with this company and recommend it to anyone who needs a new water heater.
