Heat Pump Installation and Replacement
John Goncalves and the folks from Litchfield County Mechanical are some of the best HVAC experts that I might ever hope to have had working on my house. Our 1910 seaside cottage (winterized and with space added to it in the 1980s) was never built with forced air heat and air conditioning in mind. Yet John, together with the skilled carpenters of prime contractor Gulick and Co. were able to find imaginative ways not only to hide new ductwork but to put it to good use, e.g. as benches and other convenient surfaces that actually add value to our home. The performance of the resulting system gives one superbly regulated heat and cool air from all of 5 zones just when and where you need it. I'd recommend Litchfield County Mechanical to anyone with an HVAC need. These are the people you need.

Central A/C Installation

John had come recommended by a colleague of mine. When I contacted him he scheduled a time to come over and determine a quote. We had recently moved into a 4,000+ sq ft home without central air. Needless to say, after one summer, we needed something! While at my house, I said to John â if this was your house, what would you do?â We went through a list of options including, to my surprise, a heat pump that would also provide heat to supplement our furnace. Within a few days I received a quote with several options listed as â add onesâ . At the price he gave me, I expect the heat pump to pay for itself after one full winter and, if it works as I think it will, the ROI on the heat alone, if oil stays where it is, will probably pay off my entire HVAC project within 10 years. I shopped around and recognized that Johnâ s quote was by far the most competitive and fair. Every day he was there he was prompt, every morning sent me a text to let me know an expected time of arrival, and most importantly every day John showed up with a smile and positive demeanor. When my twin daughters got home from school every day John would say hello and have a quick talk with them. Now theyâ re asking when John is coming back! I am impressed with the quality of work, craftsmanship, and attention to detail that John put into this project. One example: every morning John would place down carpet protection and wood protection for the areas he would be walking that day. After the project was completed, John checked in to make sure everything was good. He also had an idea on how the fan could be even more quiet so he actually came back and made the adjustment (and it is more quiet). Best of all, he stuck to the original quote and within the time we had planned. I obviously highly recommend John and his team for any project you have!

We hired LMC to install central air conditiong systems in 2 different houses we have owned, John is courteous, thoughtful, knowledgable and creative. He carefully plans and provides the most cost-effective and energy-efficient solution possible. The quality of his work is top-notch. Can't say enough good things about his work. Truly a five-star business.

In this day & age where contractors don't get back to you on an emergency call, John Goncalves is the exception. The work was performed in the time frame that he said it would take, the work-site was cleaned at the end of each day and he walked me thru the system on how it works and what I need to do as far as regular service is concerned.

Litchfield County Mechanical has been wonderful to work with - from day one with the initial installation of our boiler, to now a few years later with its maintenance and cleaning. John has been great, addressing any questions I've had promptly and thoroughly. His prices are very reasonable, and his work is impeccable - very clean and organized. I wish other contractors/businessmen were as easy to work with, and worked to his high standards!!

My project was installing a ductless heating and a/c unit. LCM far surpassed anyone else I had looked into for the job. The quote was perfect and they tailored to what I needed to have done rather than trying to sell me the world. They were very trustworthy and helpful from show up times, to keeping their work area clean at the end of each day, to any questions I had in regards to the job. I would recommend them to anyone who needs any heating or a/c work done.

John of Litchfield Mechanical is a very reliable, friendly and quick to respond individual. He was very helpful and attentive to my parents and my needs for a new furnace/boiler. As we were holding off to replace of our boiler for the Spring of 2016, the tank for the water to the boiler busted in Dec, John came with a temporary one. I then didn't want to take chances as our boiler was already over 40+ years, I spoke to John if we can change it out sooner and he worked us into his busy schedule. LCM is a great business and John is very professional and the most honest I've met. My parents (especially my father) are very satisfied with the new boiler and a little extra project that we had John do for us. Thank you John

Litchfield County Mechanical did a fantastic jobs replacing our central air system. After getting several quotes we decided to go with John even though he could not do the job immediately. It as worth the wait! He was far more reasonable then the other local (Fairfield County) companies and actually did the job himself unlike the local companies that send salesman then random guys show up in your house. My air con works great! I'm glad I went with Litchfield County.

IF you are in need of Heating and Air Conditioning work, look no further than Litchfield County Mechanical! Having owned and built a few homes, I can easily say that John is by far the best contractor I have ever hired and really just a great person. John did a complete furnace and central air replacement including all of the duct work. The job was on time, on budget and considering the scope of the work needed, he was incredibly neat. He and his team took there shoes off every time they entered my home! The quality of the system is state of the art. He has been back to service my system and he is always reliable. Litchfield County Mechanical is my go to company for my HVAC needs. I have already referred him to family and friends.

John replaced our old oil furnace with a new propane furnace. The work he did was great and done very quickly. He took the time to thoroughly go over and explain everything and you can tell he really cares and takes pride in the work he does. I would highly recommend him.

John did a complete furnace replacement including our antiquated zone valves that would not work with any modern programmable thermostat. The work was meticulous and we are beyond impressed with it. He included ball valves at service points and created a completely serviceable setup that is frankly quite amazing. The previous unit was clearly done 'on the cheap' and only after seeing how well a furnace can be setup do we realize how poorly the previous one was. I cannot recommend him enough.

John is one of the most reliable, professional and honest service person I have ever hired. He responded to our initial request BEFORE anyone else - yes - we had requested several bids - and his attention and timeliness went WAY beyond expectations. I highly recommend you consider John's company for your heating/cooling requirements.

I can't thank John enough-the job turned out to be much bigger and more time consuming than either of us could have imagined (due to how poorly the previous installers work was) but he was very patient and did a superlative job. Being a first time home owner, I am very pleased with the level of professionalism John has shown me. He is very friendly and knowledgeable. I can only hope that if I ever need a contractor of another trade, that they will meet his level of expertise.
