McDonald Heating, AC and Plumbing works out of Auburn, and the company says it has served Auburn, Worcester County and surrounding communities since 1987. Its website describes HVAC and plumbing repair, installation and maintenance, and lists Mass Save Certified Contractor status. Its Massachusetts plumber license (3553-PL-C) and HVAC license (594-SM-B) are active on the state registry. Its BBB grade is A+. A recent customer said Chris gave honest information and that it did not feel like a sales pitch. A 2026 customer said the company had replaced their AC system about three years earlier, then came back to replace their gas boiler; Chris came out to provide the estimate and explained what would be replaced and why. That 2026 customer said Bill stopped by ahead of the installation to walk the technicians through the setup, and that the new Bosch boiler was running and the heating was "working exactly as expected." A 2025 customer said they had mini splits installed over the summer, with the installation led by Ray and Michelle, the owner, coming by to check on everything. A 2025 customer wrote that two mini split units were installed, called the installation "spotless," and said Chris's pricing was competitive compared to others in the area. A 2025 customer said a tech, Allen, came out for a blower motor issue after 4 P.M. when the parts department was closed, then called around 7:00 A.M. as promised; that customer said Michelle, the owner, also came out to address their concerns. A 2025 customer who replaced their entire HVAC said the company went over every detail of the project. A 2026 customer said the company had been to their house multiple times over the past 10 years. A recent customer said the AC was fixed in under 30 minutes after a capacitor was replaced, but the bill came to $802. After a call to the office it was lowered to $562, which the customer still considered too much, and the bill was not itemized. A wbjournal.com page lists the company among notable runners-up.

Chris provided me with incredibly valuable information. Clearly someone who is extremely knowledgable. I did not feel like I was getting a sales pitch from chris. Just honest information.
My AC was down the service man came quickly and fix the problem in under 30 minutes, the service call I was told $230.00 for the first hour he replaced the ac capacitor which is about a $40.00 part he then informed me the bill was $802. I was upset called the office which they said. They would lower the bill by $75.00 which I said was unacceptable so they lowered the bill to $562. Which is still to much the bill was also not itemized as it should have been. I paid this. So buyer beware.
Excellent, knowledgeable and prompt service and fair pricing. My sixth sense tells me I can trust them. They have been to my house multiple times over past 10 years and were very dependable each time
We’ve worked with McDonald Heating Air Conditioning Plumbing, Inc. twice now. And both experiences have been excellent. They replaced our AC system about three years ago, so when it was time to replace our gas boiler, we didn’t hesitate to call them again. Chris came out to provide the estimate and clearly explained what would be replaced and why. Both Chris and Bill also pointed out what components from our prior system could be safely retained to keep the project as cost‑effective as possible. Bill stopped by ahead of the installation to walk the technicians through the setup and ensure everyone was aligned on the work required. That level of preparation gave us a lot of confidence. On installation day, the team was here the entire day and handled everything professionally and efficiently. The new Bosch boiler is running perfectly, and our heating is working exactly as expected. McDonald HVAC continues to deliver reliable, high‑quality service, and we’re very pleased with the results.
McDonald's advertises as a "Trusted Plumbing, Heating and Air Conditioning Service Company." We concur: over the summer we had mini splits installed and you can count us as one of their satisfied customers. We could not have asked for nicer people throughout the whole process. First, we met with Chris who patiently answered all of our questions. Next, we met Bill, the Project Manager, who possessed incredible credentials. My wife tested his knowledge by putting forth a multitude of questions and even fired off questions about our present heating system. Bill passed the "Test" with flying colors. The final step was the actual installation and the McDonald's Team of Auburn stepped up again and showed their true colors, led by the amiable and personable Ray. My wife referred to Ray as a "gem": so patient, so efficient and so kind. I may add, Michelle the owner, came by to check on everything. Yes indeed, the mini splits were enjoyed & appreciated especially during the "Dog Days" of August; we both agreed that the mini splits installed by McDonald's of Auburn was a good decision.
