Justin Nuno HVAC & Plumbing says it handles heat pump, heating, cooling, water heater and plumbing jobs across Windham County, listing towns from Willimantic and Mansfield to Coventry, Columbia, Chaplin and Storrs. In a 2022 review, a customer said Justin answered the call immediately, came out the same day to inspect the system, offered 3 different quotes and replaced the entire heat pump system. A 2022 customer wrote that Justin installed a second heating zone in the house, then cleaned the affected areas and left the floors spotless. A 2024 customer said he came out in icy, snowy conditions to fix a furnace issue, at prices they called very fair.
Can not recommend him enough, he came out and fixed our furnace issue in the icy snowy conditions and was incredibly pleasant. A+ service and at very fair prices.
Justin is a real professional. He is punctual, very knowledgeable with excellent work ethics. After his work was done, he nicely cleaned all affected areas and left all the floors spotless. He installed a second heating zone in my house, and I am positive that I will hire him again for any HVAC or plumbing projects or services. I wish all contractors were like Justin. I fully recommend Justin's HVAC & Plumbing.
Justin is the guy you want working on your residential HVAC system. He answered my call immediately, was out the same day to inspect my system, and was prompt with email responses to questions. He provided 3 different quotes for things we talked about and performed the replacement of my entire heat pump system flawlessly. I would not hesitate to recommend his services to anyone.
