High efficiency boiler conversion.


Product or service reviewed: Heat and hot water propane boiler

Technician: William, Damon, Matt

Dave provided a quote for this system in May 2023, and when we finally got around to the project, everything went smoothly according to plan. The technicians were efficient and organized, and Will came back a second day to check zones. Dave and his crew have also installed 4 min splits, which have been wonderful during our hot summers, and on cold nights. We recommend Wittig Mechanical highly.

New Bosch Hybrid heat pump/gas furnace installation.


Product or service reviewed: Residential Heat Pumps

Technician: William, Damon, Chandler, Sean

I was referred to Wittig Mechanical by a colleague and I must say, it was one of the best recommendations I have ever received. Dave and his team operated with a high level of professionalism throughout the installation process, which spanned over multiple days. The team consistently arrived on time, worked diligently, and demonstrated a strong sense of integrity in representing their company.Following the installation, Dave remained actively involved in assisting with the processing of my rebate paperwork through Energize CT. He oversaw the entire process from the initial inspection to the final touches, and even made a special effort to come on a Sunday morning to ensure my system was up and running smoothly. I wholeheartedly endorse Wittig Mechanical for all HVAC needs and plan to exclusively work with them in the future. Thank you for the exceptional service.

Wittig Mechanical pricing was very fair. Their quote was significantly lower than other companies. They completed the job to our satisfaction and were responsive and patient with answering our numerous questions! Daves crew were all courteous and worked very well as a team. We are very happy with the end product.

David's crew was excellent. They were courteous and professional and did a great job including explaining the workings of the system to us. David was a big help in selecting the system and helping with rebates and other paperwork. Would highly recommend them!

Product or service reviewed: Heat Pump Instalation

Technician: William David Chandler

I used Wittig Mechanical to install a brand new heat pump system to my house located in Massachusetts. David was very professional, kind and patient dealing with the Mass Save program, so I could take advantage of their 0% interest financing and also to get the rebates. His work was very neat and took in consideration all my future plans to renovate my basement. All the ducked work was done thinking of that. Im very happy with the results and Id highly recommend his services too. Thanks David and Wittig team.

Oil furnace and ac replacement


Product or service reviewed: New heater and and central air

So happy my buddy recommended these guys. I needed a new furnace and central ac. The big corporate companies wanted to charge me more than twice what Wittig did it for... For the same exact furnace and ac units! They were in and out in a day, nice and friendly, and took care to leave to area cleaner than when they came. Thanks Wittig

Magic Pack HVAC Unit Replacement


Product or service reviewed: New heating/AC unit in apartment

Technician: Chandler and matt

Both Chandler Miller & Milo Kiro were professional and personal. Replacing the unit on the 3rd floor is not an easy job. Chandler explained the service as it was happening We appreciated the service and we are most grateful. This is a reflection on the training that the owner, Dave Wittig, has performed.

Air conditioning replacement


Product or service reviewed: Central air

This company did a great job. Two guys did the job and they made sure everything was working correctly before they left. Put drop cloths down to minimize the mess. We had our whole central air unit replaced. They answered all our questions and they stand by the product. We will definitely use them when we replace our furnace. Highly recommend!

Product or service reviewed: Furnace & AC

Needed a new furnace and AC. After getting a quote from a local competitor that seemed high, I reached out to Wittig Mechanical based on a recommendation from a friend. Their price was significantly less for a better quality product. Installation was fast and barely knew they were here great crew of guys. Everything is working great!

Product or service reviewed: Boiler Maintenance today... and Boiler Install (3 years ago)

Wittig Mechanical did a wonderful job 3 years ago installing my new boiler and zoned water heater. I never run out of hot water anymore an the efficiency of this new boiler has exceeded my expectations. The crew were on time, professional and answered all of my pesky questions. Today's technician was also perfectly on time, quick and efficient. And I appreciate that he was kind towards my dogs and professional towards me! Great company!

Product or service reviewed: Hot water heater install

Woke yesterday to no hot water and was led to your company by my neighbors recommendation. Contacted Dave first thing in the morning, sent some pictures and had a quote back quickly. Was greatly surprised that they would be able to get my replacement hot water heater installed late that same day. Chandler and Will agreed to work late to get me up and running again. They arrived right in time, were very professional and did great work with only my new water heater as evidence that they were even there. Being in the service industry myself, I'm familiar with good work practices and professionalism which they had in abundance. Thanks again to Dave, Chandler and Will. Highly recommend them.

Product or service reviewed: Radiant Heaters, Gas Furnaces, and Combination Boiler Installation

Dave and his team did an amazing job at our 5,000 square foot facility! They installed two radiant heaters for our warehouses, gas furnaces for both office areas, and a Navien nx94v combination boiler to service all 4 bathrooms. His team was very respectful and helpful throughout the entire process. We highly recommend them!

I have been using Witting Mechanical for a few years now for our commercial and residential properties and highly recommend. The owner is very knowledgeable and was great coming up with solutions for our server rooms which can be difficult with all of the systems involved. Great for all size jobs

Product or service reviewed: HVAC/Plumbing

Can’t say enough good things about this crew. Great price, showed up when they said they were going to, finished promptly and cleaned up after themselves. Having a contractor show up on time and finish a job in 3 days is almost unheard of these days. These guys were great and would highly recommend them for any HVAC/Plumbing jobs you may have.

These guys are awesome when everyone else was to busy to get here they got it done, showed up on time. Great guys to talk to, they respect your property, double checked all the work and didn’t leave until everything was tested and working properly will be using to service my heating system this winter
