Verified record
A central air unit misdiagnosed several times over one summer, then replaced along with the rest of an HVAC system more than 18 years old: that is the kind of call EMP Heating And Cooling LLC gets. The company says it has been in business for 10 years and offers free estimates and 24/7 emergency service, and its website lists a service area running from Greenwich and Stamford to Bridgeport, Fairfield, Stratford and New Haven. On Google it shows 5 stars from 44 ratings. Recently, a first-time customer said they got same-day service on an old AC system, and that Eric and his team were clear about its issues. A recent customer said the technician quickly resolved a thermostat issue. The 2025 customer with the misdiagnosed central air said the company found the real issue, replaced the whole system, and charged a reasonable price. A 2025 customer who met with nearly ten contractors for a gas boiler replacement said the technician explained every step and provided detailed photos when the job was done. A 2025 customer said a technician installed an on-demand gas boiler and left the site cleaner than when he started every time. A 2025 customer said Eric installed a new central air system for first- and second-floor apartments, replaced a water heater, and charged a fair price. A 2025 customer said Eric installed two new hot water heaters in a barn's boiler room the next day. A 2025 customer about to take on a new renter said Eric found an issue with one of the outside condensers and explained the options for new units by performance and price. A 2025 customer said Eric, the owner, explained everything he was doing on a new dual-zone mini split. A 2025 customer said Eric gave a fair price on a furnace repair before starting any work. A 2026 customer said the owner came to fix a boiler thermostat and explained the process well enough that they could manage it themselves.

First time customer and a great experience. We contacted same day and received service for our ac system. Eric and his team did great on our old system and was clear on the issues with it. Would definitely recommend to anyone
The technician was extremely professional, knowledgeable, and quickly resolved my thermostat issue. Everything is working perfectly now—I truly appreciate the excellent service!
The owner of the company came to my house to fix the boiler thermostat, he was able to explain me the whole process to the point that I was able to understand it and manage it myself. I had a great experience talking to him.
I’ve hired Jacob for over ten years as he has installed and maintained many hvac systems for me. There when he says he will be and always finds the issue without overselling. Great trustworthy contractor!
What can I say Only that Eric is a true professional Showed up Fixed the problem with Zero issues Highly recommend Thanks Eric
