HILLCO’s dependable, professional HVAC services have resulted in satisfied residential and commercial customers throughout northwest metro Boston. Here’s what some of them have to say:

Chris and his team are consummate HVAC professionals. They installed an entirely new heating and cooling system in my 100 plus year home without a hitch. The entire process was very professional, from the layout of the system to their responsiveness and meticulous installation (not a speck of dust left behind). Chris’s quote was also very competitive given that he installed top notch equipment at a very reasonable price. Needless to say, we are extremely pleased and would highly recommend Hillco.

Chris, the owner, was very responsive from day one. He was timely in estimating the project, responding to questions about his quote, and incredibly fast in scheduling the installation of my central air conditioning system. From the time the approval was given to complete installation was less than one week. HILLCO did a very thorough job, was pleasant to deal with, and met all commitments, including a very professional installation job.

I first hired HILLCO to install a new humidifier. I found them reasonable, polite, and very honest. Following the first time, I called them again when my heater was not working. They responded to the call quickly and helped with the problem in a very cost-effective manner. I would definitely hire them for future projects.

I had four companies come out to give me a quote to replace an old central air conditioning unit. HILLCO not only had the best price but also was able to get my project done in the least amount of time. Chris was professional and very knowledgeable.

AWESOME!!!! That’s all that needs to be said. Chris was great to deal with. He installed my central air conditioning system in ONE day, start to finish – and it was a very hot day to do it. HILLCO cleaned up everything when they were done and took all the empty boxes away. It was a very complete and professional installation. I have a feeling that when my neighbors see the job they did, Chris will be getting calls from them. I recommend HILLCO to everyone – thanks Chris!!!

Good communication. Installing the clean dryer vent was more involved than estimated. They had to replace the existing dryer vent ductwork. My customer (I am a carpenter and contacted HILLCO to perform this service for her) was pleased with the outcome, and she additionally had them install a new thermostat for her heating system. She reported that her clothes get dried in half the time it used to take. I would hire them again. Thank you HILLCO!

HILLCO was great from start to finish. They were prompt, returned calls, arrived on time, and provided both the service and honest recommendations for my central air conditioning installation that seems to be all too rare these days. It was a pleasure doing business with them. I would not hesitate to recommend them and to use them for future projects.

HILLCO was far and away the most knowledgeable air conditioning contractor I spoke with. They provided detailed answers, and more importantly, reasoning to back up their proposed air conditioning design for my house. Their work is exceptionally clean and tidy; the system works perfectly.

HILLCO was completely professional, and the project was completed on time. They made the central air conditioning installation seem easy. There was wonderful communication with us throughout the project. The system is quiet and is just what we wanted. We would recommend HILLCO with no reservations!

Chris of HILLCO was AWESOME! He was extremely professional, on time for the estimate and day of work, and very thorough with the central air conditioning installation. Chris and his crew cleaned up meticulously after the job was complete and walked me through every detail of the installation. Even after the job was complete, Chris still went above and beyond to make recommendations to get the most efficiency out of our new system. I would not hesitate to recommend Chris to anyone interested in his services.

The central air conditioning installation was finished as scheduled. It was very pleasant to work with the HILLCO crew. There were no problems, and I was very pleased with overall quality, workmanship, and knowledge. I am very satisfied with the results. Also, the total cost was reasonable and within my own estimate.

HILLCO is great to work with: punctual, efficient, helpful, and friendly. Chris is easy to reach, and if he misses your call, he calls back quickly. When he stopped by for the estimate, he took the time to explain what heating system would work in my house and how they would install the duct work. The project turned out great!

All the work was done professionally. My central air conditioning installation was installed complete in two days. Everything was cleaned just like they found it. I would recommend HILLCO to friends and relatives.
