Nate our technician was informative and friendly. He checked our boiler over and made sure it was ready for winter and functional. Communication on our service window via the text system was poor. We were able to make same week appointment. Clear options with price points on possible future services and upgrades to our systems were presented to us. Technician good. Service good. Late appointment after the window was ok but not getting any update and having to call thinking no one was coming...

The technicians diagnosis took a few days. They listened and explained how to resolve our situation very well. This is our first experience with McQuillan. We are impressed by the knowledge and level of service. A big thank you!

The appointment was set up very quickly, and the professional came to my door with a smile. He was warm and friendly, but also professional in his regard for all the things I need done for my basement bathroom. He provided an estimate within a half hour of his arrival and I was grateful I will have to make difficult decisions because I was impressed by your service thank you and thank him please Mary.

I had a great experience working with Tony from McQuillan Home Services LLC! He was professional, knowledgeable, friendly, and easy to communicate with. He took the time to explain everything clearly and made the entire process smooth and stress-free. I really appreciate his professionalism, attention to detail, and excellent customer service. I highly recommend Tony and McQuillan Home Services to anyone looking for reliable and quality service!

Tony is one of the absolute best technicians I have worked with across any company or industry. He is personable, professional, polite, and extremely knowledgeable about the products and services he provides. He took the time to explain everything clearly and made the entire experience easy and stress-free. Because of Tony, I will only use McQuillan for my plumbing needs. McQuillan is fortunate to have someone of Tony’s caliber representing their company. Highly recommended!

5/5 Stars Highly recommend! Tony was professional, punctual, and diagnosed the issue right away. They fixed everything quickly, left the work area completely clean, and charged a fair price. It’s hard to find reliable service these days, and I will definitely be using them for any future plumbing needs.

Great service. We have an issue with low water pressure and Zach looked over our plumbing and helped determine where the problem could be coming from. Zach went above and beyond what we expected and he was very knowledgeable and professional. He also identified some older gate valves that were needing to be replaced in the near future. He didn’t try to sell us on doing the work but instead provided us a competitive quote and told us we could call if/when we decided to have the work done. We...

Awesome service! Great that a little background profile information was provided about the technician that was coming out. This provided welcoming feeling as to who will be on site to do the service. We cannot find words to express how Technician Adam H. came out to diagnose our electrical issue. After patiently listening to the entire story about a portion of the house has no electrical power... he was able to find out the issue outside. Adam took his time to explain the entire power...

We had two projects completed recently and will be sure to call McQuillan again when our need for their services arises. First we had a furnace replaced. The work was professionally done. The crew was all hands on deck and diligent in completing the job in a timely manner. It looks and works great. Next we replaced an old laundry tub and the technician who arrived was able to diagnose the fix and complete the project same day. In both cases, the old units were completely removed, saving me a...

options, not pressure

We guide. You decide.

We present your options and you choose – no high pressure close. Explore the honest pros and cons of each below.

Boiler Tune-Up

A technician inspects the boiler, circulator pump, and system pressure, which can catch a developing problem before it turns into a repair call.

Often A Good Fit When

Your boiler is running, but hasn't been checked in a while and you'd rather catch a small issue early.

Pros

  • Helps catch developing issues early
  • Supports reliable performance
  • Checks the circulator pump and system pressure
  • Costs less than an active repair

Cons

  • Will not fix an existing problem
  • Cannot reverse normal equipment age
  • May reveal a repair you still need

You’ll get a flat-rate price on all three before anything is decided.

DIY VS PRO

Should you do it yourself?

There is one simple thing you can reasonably keep an eye on yourself. Check whether your boiler's pressure gauge reads within its normal range, and note whether the system is making a new or unusual noise before you call.

Adjusting pressure, addressing a leak, and repairing internal components involve a pressurized system and call for professional tools and training. If the pressure gauge looks unusual, you notice a leak, or the system will not turn on, it is time to call a professional rather than continue troubleshooting on your own.

DIY versus Hiring a Pro
An Honest Comparison DIY Hiring a Pro
Time Minutes for a visual check Often available same-day
Real Cost Just your own time Upfront quote before work
Insurance Varies by your policy Provides a documented service record
Warranty Can affect coverage terms Backed by our workmanship
Safety Safe for observation only Handles pressurized components safely

Do the looking. Leave the fixing to us.
