What does a furnace tune-up include?

A McQuillan technician inspects, cleans, and tests key furnace components, checks the ignition system, and confirms your thermostat is working correctly. A tune-up is meant to catch developing issues early, not replace a needed repair.

How often should I schedule furnace maintenance in the Twin Cities?

Many Twin Cities homes benefit from at least one furnace tune-up a year, ideally before the coldest months. A technician can help you decide what schedule makes sense for your specific furnace.

Will maintenance prevent all furnace problems?

No. Maintenance helps catch developing issues early and supports reliable performance, but it cannot prevent every possible failure, especially in an older furnace.

Can I do any furnace maintenance myself?

Checking or replacing your furnace filter and confirming your thermostat settings are reasonable homeowner tasks between professional visits. Checking the ignition system and burners should be left to a professional.

Does regular maintenance affect my furnace's lifespan?

A well-maintained furnace generally experiences less strain than a neglected one, which can support more consistent performance over time. McQuillan does not guarantee a specific lifespan outcome, since it depends on the equipment and how it is used.

How does McQuillan price furnace maintenance?

McQuillan uses upfront pricing. You will see a quote before any additional work is recommended, and you'll never pay more than you're quoted.

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.

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...

Should you do it yourself?

There are a couple of simple things you can reasonably do between professional visits. Checking or replacing your furnace filter on a regular schedule and confirming your thermostat is set correctly both help your system run the way it should.

Beyond that, checking the ignition system, burners, and electrical components calls for professional tools and training. A yearly professional tune-up covers this deeper check that basic homeowner upkeep cannot.
