Outstanding company and outstanding work performance. Out of many estimates, Cawiamca offer came by e-mail in 24 hrs from the visit. After few clearing Q&A, final detailed contract was sign in person in 48 hrs. All communication was done with the owner OVER THE WEEKEND promptly, with understanding, concern and his willingness to help. Totally impressive for business owner to do that on weekend. Best estimate , best professional work and my gratitude, thanks and best wishes to owner Mr. Ron Pelletier.

Super quick and reasonably priced. Job was completed less than 24 hours after I called.

Friendly, efficient and extremely competent installation of a new compressor and coil for a forced air system. Also came in with the best estimate. Will definitely use in the future.

Amazing crew!!! So respectful and conscientious- I couldn’t be happier with the level of service!!! Thank you so much!

Really enjoyed working with them! Very clear communication, and high quality work.

I have used these guys for six or seven projects now and they are amazing. I have used them both for heating and cooling and their electrical services. John and Brian are amazing electricians and more importantly just great and fun to be around people. I would recommend them to literally anyone and I trusted them to work on my parents home. My lifelong contractor told me that they were the best electricians he's ever worked with. I really cannot sing their praises highly enough and if you have any hesitation about them I hope my review is somewhat helpful in allaying them. Their work quality is top notch and they're professionalism cannot be beat.

John Valero and his partner did an EXCELLENT job. John was professional to work with from the beginning of the project through completion. He was extremely reliable (always showed up on time) and worked with my timeline. I would highly recommend Cawiamca Electrical and John to anyone needed electrical work.

Work was done promptly and efficiently, all work was professionally done and property left spotless. Have since used for other projects.

Great communication. Did the job quickly and correctly at a fair price.

Very knowledgeable and competent. The work was done carefully and professionally. I recommend the company wholeheartedly.

Excellent job by Brandon who was very patient and through with his work.

The team from Cawiamca did a great job for us! Brian, John and Ben are very professional. The team installed some new fixtures and did some troubleshooting. They work quickly and efficiently. We would highly recommend this company.

Excellent team of professionals, polite, clean and precise in their work. I would recommend for any and all services needed!!

Exceedingly STELLAR work; BEYOND professional decorum elicited by the company’s OWNER AND staff MEMBERS (specifically the technicians that performed the installation). Overall, we HIGHLY recommend this company to neighbors, family, friends, coworkers & even strangers in our community that may be in need of any HVAC or others services for their homes and/or businesses. Financially, they were on par with our anticipated costs for the work we needed done. FAST, QUALITY WORK that we’d NEVER hesitate calling on again for any future needs that this EXCEPTIONAL, ‘5-star worthy’ company provides! Thank you especially to Ron, Carlos and Brandan… we truly enjoyed meeting you and the pleasure of your company while you worked diligently in our home was all ours. Perhaps this review seems “over the top”or contrived, but we truly wanted to reward this company properly with a review that sufficiently and congruently matched their “talk with the walk” behavior. As you (a co-consumer) know there are so few these days that that elicit good, old- fashioned business ethics. We want you to know this was honestly a job TRULY well done!

This was the best experience with a company that I have never had come to my home before. I run an Airbnb out of my residence and my central air stopped working in the middle of a heat wave. I called all the service people in my area and no one could come for 2 weeks. I was panicked! I found Cawiamca on Angi's list. They are located in Saybrook CT. I wasn't sure they would come all the way to my home in Mystic. The owner himself called me and had someone come out THAT VERY DAY!! And the problem was fixed within an hour. I can't say enough good things about this company and the service man that came out. Fabulous, friendly, and expert service! I highly recommend them!

I cannot recommend Cawiamca strongly enough. When we look for a company to do work on our house we look for three things: a track record of good work, fair price, and reliability. Cawiamca has all of these things in spades. The first company to respond to us? Cawiamca. First with a quote? Cawiamca. Our heat pump installation was a big project and took several days, and the Cawiamca team were a pleasure to have at our house. They did great work, left things cleaner than they found them, and always kept us updated. Equally as importantly- Ron and Jeremy are incredibly responsive when I had a question or a need, often responding the same day. Cawiamca is deserving of your business- hire them now!

I'd like to give a AAA+ rating to Ron and Jeremy owners of Cawiamca LLC. These guys are top notch! Ron provided competitive pricing for my new furnace system and installation. Jeremy did the install in less than a full day. I've had the system for little over a year. They came back this fall for an annual cleaning and I signed up with them for a service contract. Fast forward to December 24th Christmas eve. We lost power in Essex and my generator tripped the furnace off due to a surge. I called Ron who was out of state at the time. He phoned me back within 15 minutes. He then sent Jeremy over to survey and fix the problem. Jeremy explained he was on his way out for family festivities when Ron called. He got it up and running quickly. It was a very nice Christmas present for me. I can't stress enough how rare great customer service is these days. Cawiamca LLC. provides awesome customer service! —John M, Essex CT

CAWIAMCA did an outstanding job installing 2 high efficiency ductless mini splits – 1 at each end of my house. The owners Ron and Jeremy worked with me patiently on the system sizing and selection process, rebates from my power company, income tax credits, etc. Everyone on the installation crew was polite, conscientious, and knowledgeable. They came back next day to complete the installation of the second system despite snow and freezing rain!!! This company is well equipped to do the job efficiently. CAWIAMCA's price was much lower than the other 2 contractors I got estimates from (who planned to use concrete blocks to support the outdoor condensers). CAWIAMCA used quality steel bases with tall legs to support the condensers and keep them higher up away from snow, leaves, mice, etc. Nice looking installation. I could not be happier with a company. :-) CAWIAMCA!!!

It went well very responsive issues are being addressed as they come up

This company was outstanding and excellent Jeremy thank you. Would recommend him for his top notch services ?

It went good, the outside unit went bad, they had one in stock went back to there shop came back and had use up and running the same day. Great Job! The work quality was excellent. Thank You Roger

I had a heat pump system that died. I must have called at least 10 contractors and was living with no heat for 2 weeks before I got in touch with Cawiamca. Jeremy contacted me back quickly after I submitted a request for a quote, he was able to come out first thing the next day. Out of all the contractors that came out to look at my old system, Jeremy was one of a few who looked at my system thoroughly and was the only one that was honest with me about the old lineset and suggested another solution, the mini split system, which is a cheaper option for me. He provided me a quote the same day and was able to start the job as soon as I agreed. His team arrived on time first thing in the morning, finished the job quickly and beautifully, cleaned up after themselves and removed my old system. I have to mention that Jeremy was very responsive whenever I have questions, day or night. I could not have been happier with the outcome. I would highly recommend Cawiamca to anybody and sure will recommend them to everyone I know.

Excellent. I highly recommend this company. Prompt service, very fair pricing. Researched my furnace to better understand my unit and attained parts needed to repair within a 1/2 hour. Their technician was a great guy.

The Cawiamca team was very quick to respond when my furnace went out before a storm and was able to provide a replacement furnace and completed the installation within 24hours. Great team and great service, and I will be reaching out to them with any other heating services that I need.

We were referred to Cawiamca in Old Saybrook, CT, 860-661-5913, by Fujitsu United States, to fix our Split System air conditioner that stopped working on the hottest day of the year. Cawiamca technicians responded immediately. They are professional, efficient and personable. They analyzed the problem and fixed it for a very reasonable fee. We couldn't be more pleased with the service they provided. We will certainly use Cawiamca if needed again.
