Newington, CT

First time dealing with them. Annual service on a Navien Combi unit installed 2 years ago, they were great would highly recommend!

Cromwell Electric was wonderful to work with. Jeff gave a clear explanation of estimate for mini split a/c and installation happened within a few weeks (earlier than expected)! Tom, Jason and Ken were extremely professional and friendly. Got work done in a day without interrupting us in the home. Everything was cleaned up and took time showing us how to work the units and care for them. We will continue to use this company for multiple services when needed. A+++.

Eric Mori came to do my annual service and he was exceptional! He took the time to answer all my questions, thorough and polite ! I was so pleased and he was neat and timely! He did both my AC and heating!

In the middle of a heat wave, our AC quit. Having used Cromwell Energy for furnace maintenance previously, I recalled the excellent service they provided. They did not disappoint again. Even though they were scheduling a week out, a technician became available the next day. Eric was professional, courteous, answered all my questions (and then some), and clearly was an expert in his field. Thanks to Eric and the excellent office staff, our AC stands ready for the next heat wave! Highly recommend Cromwell Energy!!

Cromwell Energy has always given us excellent service and we highly recommend them!

I have used Cromwell Energy for more than 15 years. Eric performed the annual tune-up of my furnace and central A/C. He does a great job of explaining what is being done, was prompt, professional, and experienced. Highly recommend!

Great service today on my air conditioner from Eric! He knows his stuff 🙂

We called Cromwell Energy for a recent AC issue because they promptly fixed an issue we had a cpl years ago. Rep Eric came to our home, quickly identified the issue and had the AC running in no time. He was obviously very knowledgeable as well as courteous and thorough! Once the AC was on he verified the issue was resolved completely before leaving. Cromwell Energy was reasonably priced, will definitely call them again!

Central A/C wasn't working when I needed it. Cromwell Energy sent Eric over the same day. They called before he came and he came when he was supposed to. He was very professional and methodic in tracking down and resolving the issue. I have been a custom for years and the service is always excellent.

Great service, extremely professional, very responsive to heating and cooling needs! My review is based on many years relying on Cromwell Emergy’s services.

Have used Cromwell Energy for several years and always happy with their work. Eric performed the annual service on my HVAC today, very pleasant and knowledgeable technician.

We have been a customer for many years and are always extremely satisfied with the service. Eric was out today to check our air conditioner unit. He was very knowledgeable, courteous and professional. We would recommend Cromwell Energy and we are grateful for the great service with Eric!

I recently encountered a problem with my A/C unit, and Cromwell Energy promptly sent a technician. He conducted himself professionally, clearly explaining the problems and available repair options. Before the technician was dispatched, I had the opportunity to speak with a service manager which is impossible for some companies. So big shout out to their technician Keith, great job.

I have been a customer of Cromwell Energy for many years. They are an OUTSTANDING Company with an Excellent staff. Eric has been servicing my system for the past few years and I have found him to be VERY Professional, Knowledgeable, Helpful and friendly. What more could a costumer ask for?

First time using their service, and I am more than pleased with them. AC unit was leaking and not cooling. Called them, and they quickly scheduled me for a visit. David quickly identified the issue and fixed it on the spot. Truly recommend them.

I have been happy using Cromwell Energy for 40 years. Just wanted to comment on my experience with Eric. He has been here the last few times I needed help with my furnace and AC. He is so friendly to work with, always explaining any issues and what he did to resolve problems. In the past dealing with Brian has also been very helpful. Kim Z., Cromwell

We have been using Cromwell Energy for years and years. I can't say enough about the quality of their service--this company is amazing. They have cared for our boilers (we live in an own a 2-family) and installed a very complex, energy-efficient HVAC during a process that required multiple trips to our tiny attic and cellar. Throughout every visit, whether for installation or annual service calls, the technicians not only show great expertise, but are friendly and kind. And the office staff (thank you, Ronnie!) are exceptional, too. Thank you, Cromwell Energy! We feel lucky to be one of your customers.

Always prompt and excellent service from Cromwell Energy. Employees knowledgeable, polite and helpful. David is great and Ronnie, the secretary, is a pleasure! Lou carries on the family tradition.

Service and staff are top notch. They have exceed my expectations when it comes to customer service. Staff is super friendly, professional, and care about their customers. I would highly recommend.

Excellent service!!!!! Very competent workers!!!!!!!

I want to thank Lou and every member of his staff for the service they have provided at our office as well as my personal properties. Every member on his team is professional and cares about the client and doing a great job. Lou went out of his way to get parts overnight for a steam boiler that went down. They called me 1st thing in the morning to get the system back up and running. I am consistently impressed every time they work for me. Thank you. Kyle

I have been a Cromwell Energy customer for nearly 20 years. I have always gotten good service their techs are some of the best in the business professional knowledgeable Years ago when times got tough the owner of Cromwell Energy fronted me 100 gallons of oil so I could get by never forgot about it. Thanks Cromwell Energy keep doing what you do

We called and received quick same day service. We had just moved to the area and the gentleman was extremely helpful with educating us on our boiler system. Highly recommend this company and they will be the first company we call if another issue arises.

I've been using Cromwell Energy for the last six years for both my heating and air conditioning. I highly recommend this company,The technicians are always on time and update me on how all systems are working after they complete their work.

Terrific customer service. Thorough in the Annual Maintenance. Eric was patient explaining the filters, thermostat and efficiency of our furnace. Always prompt with our oil deliveries too! Great company!

We've used Cromwell Energy several times and they've always been responsive and professional. So when it came time to upgrade our thermostats, we knew we would give them a call. We worked with Keith to get an estimate and he was very helpful in reviewing our different options. Eric did a great job with the installation and took the time to explain in detail how the new thermostats work. He was courteous, friendly and we are very pleased!

I’ve been using Cromwell Energy for over a year now, for my oil and I used it to do a tuneup on my furnace. Eric was very thorough and he explained what had to be done and as a female owner made me feel that if anything happens I know what to do until they get to my home. I bought the Oil Heat maintenance plan and was very satisfied with their services. Great customer service too! Thank you Eric for your time and making me feel at ease.

We got some water in our basement and they came out first thing the following morning to repair our boiler! A huge relief in December when you have young kids. We very much appreciate Eric and the team!

Eric came out this morning to check my heating unit out and help light the pilot. He was ON TIME, courteous and professional. Cromwell Energy came highly recommended from a friend that is a contractor. I was not disappointed. I like that I didn't have to wait around all day for a large window of time. Thanks Eric and Cromell Energy.

The best HVAC company I have worked with, we use them at a multi-family property. Always a fast response. Everyone is well mannered and very professional. I feel like I am treated as part of the family. I would highly recommend. If your in need of their service definitely give them a call. You will not be disappointed.

I’ve been using Cromwell Energy for years and always receive excellent service. Eric performed annual maintenance on my furnace today and was friendly, professional, and informative.

I had a minisplit ac/heat pump system installed in my home over the summer. Communication leading up to installation was thorough and efficient. Installation was fast and clean. A rather large crew left virtually no trace behind excepting the new equipment. I recently had an issue where the heat was slowly diminishing (barely noticeable for a while) until it stopped working altogether. I called to inquire about it that morning and they had a technician at my house to diagnose and fix that same morning. Fantastic customer service and the price for the install came in pretty average compared to other quotes we got, without a crazy wait even approaching peak AC season.

Cromwell Energy has been nothing short of wonderful and knowledgeable to work with! When we bought our house, we were recommended to a different contractor for maintenance and repair. When our air conditioner started leaking earlier this year, the other company did not have any availability and did not seem to be worried we had water flooding our basement. Cromwell Energy came out the same day, diagnosed and repaired our system quickly and was reasonably priced too! Fast forward to today, our heat stopped working and we called minutes before they closed. They were able to come out same day on an emergency call again. Twice now they - specifically, Eric - have saved us on emergency calls. Each time, Eric has quickly and efficiently diagnosed the problem almost immediately upon arrival and repaired the affected system as needed. We plan to do maintenance plans for all of our mechanicals through them and wouldn’t use anyone else. I cannot stress enough how great they are to work with! We also get oil delivered from them and it’s been cost effective and reliable every time!

Eric and Ken took good care of my furnace and also suggested a device plan to fit my potential needs. Thank you guys!!

Great team! We've been a customer for 17 years! Team members are always friendly, punctual and efficient. Always willing to go the extra mile! Recently had a hot water heater replaced and the services were amazing!! Definitely recommend.

Cromwell Energy sales and services were the best! We had our complete Central Air replaced today. Crew was on time, friendly, very professional, fast, neat, took great care of our house while working, both inside and out. They were done ahead of schedule and couldn’t tell they were there upon completion. HIGHLY RECOMMEND Cromwell Energy!!

For the last two days, my condo was a sweltering 87 degrees day and night because my air conditioner stopped working. Fans only go so far. I called Cromwell Energy this morning and they arrived in about an hour. The technician was Eric. He was very professional and quickly diagnosed the problem. He also gave me pointers regarding changing the air filter which I had no clue about. 5 stars are not enough. I would and will recommend this company to others. I found the price to be very reasonable too. Thanks again!!

I have been a Cromwell Energy customer for over 40 years. When it was time to replace my air conditioning units, I, without any hesitation, called them for an estimate. A quick response from their estimator and new systems were proposed, based on our budget and needs.the quote was accepted. Installation was done as scheduled. The staff was just wonderful. All the employees were very respectful of my property. They were very courteous and answered all of our questions. All packing materials were removed each day they were there and the new units were installed. A quick and very neat install. Could not have been happier with everything they did. Very positive and pleasant experience!

Thank you Cromwell Energy!! We are very happy with our new Furnace, A/C & water heater. We appreciate all the assistance in finding the best & most efficient solution for our needs. Jeff & Tom & crew did an excellent job; their prompt, thorough and courteous service made the whole process very manageable & I appreciate their patience with all my questions. I look forward to dealing with Cromwell Energy in the future and will be recommending them to my friends.

Kudos to Rich and the technicians at Cromwell Energy! The cost to replace our minisplit was reasonable, the service provided by the technicians was prompt, friendly and efficient. We are fairly new to this area and we've replaced our central AC unit and now our minisplit w/ Cromwell Energy and we are very pleased w/ both jobs!

Cromwell Energy, Inc. recently upgraded our heating from oil to gas. Our house is approximately 86 years old! The Cromwell Energy, Inc team came in and gave us an appropriate estimate of the work we needed to get done. They came in and measured each cast iron heater to ensure that our home would be properly heated. On the paperwork end they were timely and responsive. When they came in to do the work they work efficiently and were able to get us heat and hot water in a day. They also cleaned up the spaces they used. We are incredibly happy with the services we received from Cromwell Energy, Inc. Thank you!

The office staff and technicians were very friendly and professional. Prompt service. I highly recommend Cromwell Energy.

Extremely responsive, professional and prompt. Fair price for high quality work. Justin was a pro.

Cromwell Energy, Inc. has replaced our heating residential boiler recently in Middletown, CT. The previous one was over 25 years old with open fire burner and inefficient. The new boiler, recommended by the Company is a cast iron, workhorse equipment made in USA. Installation of the new and dispose of the old was done smoothly by the crew of four. After half a day I could enjoy the brand new heating system, which is quiet, efficient and reasonably priced. Thank you guys!

The team at Cromwell are great. We've been using them for about 5 years now, thankfully with only a couple of emergency calls, including late at night. They've also replaced our oil tank and done other preventative maintenance. They are quick to respond, down to earth, quality work, and priced reasonably! They also provide our oil along with our boiler service contracts. I like that they have a small town feel, every time I call the office Roni answers and is so helpful. No complaints.

My a/c unit recently broke and I made a decision to replace the a/c condenser and furnace based on both being over 20-years-old. I sought quotes from 3 HVAC contractors of which Cromwell Energy ended being my final choice. Rich Drapeau was the main person I dealt with, who came to my home to review the setup and provide an estimate. He was professional, courteous and provided follow-up answers from questions I had based on interviewing the other contractors. This also included available manufacturer rebates and EnergizeCT rebates. I was able to negotiate what I felt was a competitive price and get the most updated energy efficient equipment, as well as Ecobee wi-fi smart thermostats installed. A four-man crew came the following week and they did a great job installing everything, were courteous, clean and finished in a day. Having pulled a permit, the town inspector came in afterwards and everything was properly installed, as well as the inspector commenting he has found Cromwell Energy being a very reputable and honest HVAC contractor he has worked with. I highly recommend Cromwell Energy and the American Standard a/c condenser and furnace they installed. I also will be using them for annual maintenance of the units. Rich and the install team (plus Samantha handling some the office paperwork) are a great to deal with, and I couldn't be happier with the overall experience and of course the competitive price.

Friendly and reliable...and they actually answer their telephone calls unlike other competitors in the area.

Cromwell Energy is the best!!! Keith and Eric were truly great replacing my air in the middle of this heat wave!! They also let me use some window units to get me through till they could come. I would highly recommend them, lots of integrity, hard workers, always on time, and explained everything perfectly. My dog Jaxon loved them and agrees LOL.

I have used Cromwell Energy for the last 4 years. Each and every time I have had nothing short of an EXCEPTIONAL experience. Everyone - from the actual human you speak to on the phone to the people coming to the house for service requests - are patient, knowledgable, friendly, and fair. I highly recommend Cromwell Energy!

Cromwell energy is amazing! Our air conditioning system died in the middle of the summer. They came out the next day to keep it alive enough until we could get the HVAC system replaced. The replacement was done in a day, the office staff and technicians were professional abs communicative. They showed me what they were doing and how everything worked. We will absolutely be working with them in the future and for maintenance on our new system.
