"Would leave 10 stars if I could!"
Had a technician out to our place to diagnose a heating problem we had after having a different company out that couldn’t resolve the problem, took him minutes to find problem get us parts & show us along the way what repairs he has completed, chase is very knowledgeable & is the man for any of your heating / cooling needs! I would leave 10 stars if I could!

"Transparent, very professional and leave space tidy"
I have used McMullen’s twice now this year, we had an issue with a badly piped (by another company) in-floor heat system that was leaking and the technician came in and did a great job removing the old system and installing the new, much tidier and robust system for us.
We also hired them for a gas line rough in and heater install for a newly built garage. They have always been transparent on costs, very professional, the technicians call before they come, explain their work and leave the space clean and tidy when they go.
Glen has been immensely helpful for all our questions on both plumbing and heating. It has been an absolute pleasure to deal with this company.

"Traditional Professionalism"
For several years our family has accessed McMullen’s when our furnace has needed attention. Most recently this occurred today. As usual, and with their traditional professionalism and focus on customer service, McMullen’s provided excellent and expedient service. Without doubt whenever we require future assistance we will always reach out to McMullen’s. We would highly recommend it for anyone.

"Employee was knowledgeable, quick and saved us a few dollars"
When no one else would answer the phone, Mcmullens not only answered but showed up and fixed our furnace at 11 at night, it was put for no less than an hour because of these amazing people. the employee was knowledgeable quick and saved us a few dollars, 10/10 recommend for any of your furnace issues.

"Fast, honest reliable service, excellent qualified staff"
Fast, honest reliable service, excellent qualified staff. This was my second service call in a month (for two different furnaces). Both times it was a positive experience, knowing I was in good hands. Highly recommend this company!

"I will be going with McMullens again in the future!"
I have now relied on McMullen’s twice when I’ve been in a bind. The first time was when my AC went out during a heat wave right before a long weekend. McMullen’s was the first to get back to me and responded right away. The technician was friendly, knowledge and fast. He was also very reasonable with the bill
The second time was on New Years Eve when my furnace wouldn’t start. I called multiple places and McMullens was the first to get back. They got me back up and running in no time and, again, were VERY reasonable. I will be going with McMullens again in the future!

"Honest Outfit"
This company is quick to respond and not out to rip you off on emergency repairs. We’ve had a couple and they’ve answered our call in a timely fashion and tried not to overcharge us. Other places have. Please call this honest outfit for a happy outcome.
