Best boiler installation pros near Sherman, TX

"Mechanical Comfort Systems installed a new heating and air system when my upstairs (where all the bedrooms are located) system went out in the heat of the summer on a Thursday (left for work and it was working... got home and it was 90 degrees upstairs). I had another HVAC contractor out before calling Mechanical Comfort Systems and their proposal was significantly more expensive for a lesser system than I received from Mechanical Comfort Systems (the efficiency of the system was an upgrade from existing, and other company quoted replacement with same efficiency as existing). The system was replaced quickly (on a Saturday), and the installers were great, very professional. They cleaned up after themselves, and did a great job. During the freeze this February, I had a water pipe freeze and burst. Mechanical Comfort Systems came out the day after, even though driving conditions were still terrible and all my friends in similar situation were being told it'd be several days to a week before a plumber could come unless they paid some ridiculously expensive emergency fee... I recommended Mechanical Comfort Systems to three other people I knew that also had frozen pipes burst, and they all had them come after fix theirs after I gave them Mechanical Comfort Systems information. I strongly recommend Mechanical Comfort Systems to anyone needing any plumbing or HVAC work. I'll definitely use them again... although I hope not anytime soon ?"

"Stuart is very knowledge about HVAC units and tries to repair versus replacement.  Extraordinary customer relations.

 Also scheduled adding new insulation.  His work is reliable.   We had a few hiccups on the timeline of getting replacement unit installed due to call load. We plan to use him for normal maintenance going forward.

"They were fast and efficient. Installation went smoothly and the system has worked flawlessly for over 3 years now"

"The dishwasher fix - almost immediately identified that the guys who installed a new countertop recently had not fully turned the water back on after they finished. So THAT's why the dishes weren't getting clean!  
The icemaker fix - quickly identified the problem and it's now working fine. The only reason I marked punctuality down is that there was miscommunication between the service guy and the office, to us, about when he would be back to complete the dishwasher repair. But not a major issue.
We've used these guys before to install a gas cooktop and they are smart, experienced folks who know what they're doing.

"It was great. They came on time and they cleaned up after themselves. We had to have a new UV light installed a year or so later; they came and did it and that also was great."

"I called the afternoon my A/C went out. Morrison said would be there at 9a, got there at 8:45. Looked over entire system. Fixed the problem; explained why it broke down & how to care for A/C in general. The cost I wrote in here for the service call is approximate because I also had them service the A/C at my office. I’ve known Morrison family since 2010. They are honest about what’s wrong with A/C & cost of repair, whether replacement is warranted and what can wait, and are prompt in an emergency. They did an install for a friend & she is pleased a year later when Morrison came to service her A/C - for free because it was their install. The price they charged was way lower than other people she contacted & they provided a warranty for her new A/C. Highly recommend Morrisons."

"The price was fair and they were able to start almost immediately. Asked the installer multiple times to cover his work area as to not scratch our new wood floors. Of course, he scratched the floors in multiple places. Attempted to contact the owner and he was non responsive on the issue. The unit was installed in September, come October and need to turn the heat on for the first time and there was loud clanging and metal noises. Called to have someone from this company service the unit on Friday afternoon and was told that “it isn’t that cold that it would be Monday before we could look at it” (it was 40 degrees and this is a BRAND NEW unit). Brought up that had we went with a larger company they would send someone out and they do not work after hours or weekends and was basically told you get what you pay for. I would not use this company again in the future. Will probably regret making this post when we need service again in the future."

"This company was awesome. They came on time. They were very polite. I told them about my dryer vent they cleaned at no charge. They cleaned all my ducts and vents. I only have one AC unit. They also sanitized my whole system. Made my home smell and feel great. They also installed a Uv light system that kills germs in the air. I am very satisfied with this company and their techs. They are so polite and answered all my questions.

"Nice professional job. They checked entire installation to make sure it produced power before leaving."

"I was told to confirm the code at an Autozone(for the bad thermostat) and I did. I called NTB and they quoted me 325.00 to replace it. I paid 200 dollars less at Tilden.  After they replaced the tremostat, I had to drive for a while, then after a restest, it passed inspection."
