5-Star Rated Service
EXCELLENT Based on 135 reviews Posted on In the GardenTrustindex verifies that the original source of the review is Google. The Pespisa company team are very knowledgeable, explained the options for furnace replacement and thermostat installation. They sent 4 guys for the the install that took about 6 hours . All the guys were friendly and careful caring the huge furnace in and out. They all went above expected making sure it was installed perfectly even fixing extra parts on the attached ac unit while they were here. Dominic added a high level filter box and CO2 detector for added safety. I highly recommend Pespisa for Heat and AC work.Posted on Ben LittauerTrustindex verifies that the original source of the review is Google. Pespisa was a pleasure to work with. They had smart ideas for our mini-split installation, were clean and efficient in their work, and went over and above in setting up the system. Highly recommended (having worked with several other companies, Pespisa was the best).Posted on linda ryanTrustindex verifies that the original source of the review is Google. Recently Brian and Matthew of Pespisa Company came to my home to install a new gas water heater, new disposal and repair a leaking toilet. Both men were very knowledgeable and efficient about the work they were doing. They made the appropriate improvements as well as cleaned up each area as needed, which was much appreciated. Both were very personable and I was comfortable having them in my home. I highly recommend Pespisa Company!! Thank you!Posted on Neil LajkiewiczTrustindex verifies that the original source of the review is Google. Pespisa Company installed a new boiler for my house. They were responsive to my quote request and they did a clean installation and were priced fairly. I had follow up questions and Pespisa responded immediately. I would recommend to everyone.Posted on KERRY KISSINGERTrustindex verifies that the original source of the review is Google. We were interested in replacing our HVAC with Heat Pumps and Pespisa was a terrific firm to deal with. They first did a comprehensive in home survey to make sure the new units would be perfectly sized. They quoted the most approved (by Mass Save) hardware, and their pricing was very reasonable. The installation went on time and as planned and left us with a greatly improved system that included smart thermostats and user friendly control of our environment. We could not be more pleased with Pespisa and look forward to their maintaining our system for the years ahead. Great decision on our part!Posted on Jon HoldorfTrustindex verifies that the original source of the review is Google. Colin, Dominic, Linda and the whole team at Pespisa were wonderful throughout the entire process. We needed a major renovation and partial replacement of our system and they were all incredibly responsive and pleasant to work with throughout the entire process. They made everything incredibly easy. The estimate for work they gave was exactly the final cost and very competitive compared to other estimates. I felt their approach was much more thoughtful and informed in comparison to the other estimates. Communication was always easy and they consistently showed up at the time they specified. I have never had a home project go this smoothly and run so efficiently! I am incredibly glad Pespisa did this work and would offer my highest recommendation to anyone looking into their services!Posted on Mary CarsonTrustindex verifies that the original source of the review is Google. We did a lot of research before deciding to replace our aging AC and furnace with a heat pump. We are very happy with having chosen Pespisa. They spent time discussing our questions and thinking through the best scenario for us. Everyone from the owners, to the installation team to the office team was helpful, responsive and just nice people to deal with. Highly recommend.Posted on David HTrustindex verifies that the original source of the review is Google. Pespisa did a great job with the installation of our Mitsubishi Split. We couldn't be happier with the entire experience! The process, from the initial consultation to the final installation, was seamless. The communication throughout was excellent! Pespisa was consistently prompt and professional, taking the time to clearly explain every step of the process. On the day of the installation, your team was incredibly respectful of our home, ensuring everything was done with care. We are extremely happy with our new Mitsubishi system and, more importantly, with the outstanding work performed by Pespisa Company.Posted on Marlene StoneTrustindex verifies that the original source of the review is Google. Anthony did an excellent job explaining everything, fixing everything and helping us get on your service plan for future maintenance. He is an excellent professional and we look forward to many years of working with you.Posted on Alicia GooginsTrustindex verifies that the original source of the review is Google. The whole team at Pespisa did a fantastic job replacing my ancient HVAC system with a heat pump system. I was very nervous about the process and Dominic and Colin spent a ton of time going through different options with me. Linda was incredible helpful and very patient while I figured out the MassSave rebate and financial side of things! On the day of the install, Anthony, Dylan, and Colin were efficient, kind, communicative, and kept my condo clean throughout the job. Colin followed up again the next day to check in after, as did Linda. This is a great, trustworthy, professional company and I highly recommend them to anyone having any plumbing or HVAC work done. They are super knowledgeable and able to explain things clearly. They are also easy and fast to communicate with. I ALWAYS heard back from them same day anytime I reached out by phone or email. 5-stars!
