Protect Your System. Before It Fails.
Annual HVAC maintenance and tune-up services across coastal Connecticut. Keep your system running efficiently, reliably, and safely.
The most expensive HVAC repair is the one that could have been prevented. Regular maintenance keeps your system running at peak efficiency, extends equipment life, and catches small problems before they turn into costly breakdowns — especially in the middle of a Connecticut winter or summer.
We provide annual tune-up and maintenance services for all major heating and cooling systems. Every visit is thorough, documented, and performed by a licensed technician who knows your equipment.
What's Included
Everything We Cover on a Maintenance Visit

Heating System Tune-Ups
Annual maintenance for boilers, furnaces, heat pumps, and mini-splits. We clean, inspect, and test every major component to make sure your system is ready for the season ahead.

Cooling System Tune-Ups
Pre-season AC and mini-split maintenance to ensure your system is running efficiently before the heat arrives. Refrigerant levels, coil cleaning, electrical checks, and more.

Filter Inspection & Replacement
Dirty filters restrict airflow, reduce efficiency, and strain equipment. We check and replace filters on every maintenance visit.

Safety Inspections
We check heat exchangers for cracks, test carbon monoxide levels, inspect flue pipes, and verify pressure and safety controls — on every visit.

System Performance Testing
We measure supply and return air temperatures, check refrigerant charge, test electrical components, and verify that your system is performing to specification.

Written Service Report
Every maintenance visit includes a written report of what was checked, what was found, and any recommendations — so you have a clear record of your system's condition.

Why It Matters
Skipping annual maintenance is one of the most common — and most costly — mistakes homeowners make with their HVAC systems.

Prevents Expensive Breakdowns
Most system failures don't happen without warning signs. Regular maintenance catches worn parts, refrigerant issues, and electrical problems before they cause a breakdown.

Maintains Efficiency
A dirty or poorly tuned system works harder and uses more energy. Annual maintenance keeps your system running at rated efficiency — lowering your monthly bills.

Protects Your Warranty
Most manufacturer warranties require proof of annual maintenance. Skipping service can void your coverage when you need it most.

Extends Equipment Life
A well-maintained system lasts significantly longer than a neglected one. Regular tune-ups protect your investment and delay the cost of replacement.

Great guys - explained everything Steven YatesTrustindex verifies that the original source of the review is Google. Cameron is a very professional technician. He always explains what needs to be done in a way that I can understand. He provides me with any information that I need in a timely manner. I am happy to have him doing the work on my heating and air-conditioning systems. Brian FayTrustindex verifies that the original source of the review is Google. From the moment I placed a call to Benedetto and spoke with Judie, I had an amazing experience. Judie couldn’t be friendlier, professional and can-do. Joe Benedetto then spent a lot of time on the phone with me really evaluating what I needed, and asked for measurements and photographs. Once he came out for a physical review, he had already reviewed information I sent him and had some really good ideas. Fast forward to installation day and the crew who arrived were SO amazing! Clay & Jet. Friendly, professional, knowledgeable beyond expectations, and they took such care of our home! This was the best service experience I think I’ve ever had! I can’t wait for an opportunity to refer friends or neighbors to them! Honestly, this is a company that deserves 6 stars, but I only had the option of 1-5. This type of customer service experience should be studied in business school. Thank you Judie, Joe, Clay and Jet!! Timothy MillerTrustindex verifies that the original source of the review is Google. My Mom had a new gas furnace put in. Clay, Logan, Rafael and Tim were very courteous and knowledgeable. They were very efficient and a very clean job and I would highly recommend them.

The entire crew was professional, friendly and informative about the new system. They are exceptional representatives of their company. Highly recommend. christine bondTrustindex verifies that the original source of the review is Google. We have been with Joe for many years. We appreciate his integrity, professionalism and honesty. the work ethics he has is visible in all his employees, from the "put you at ease" ladies who answer the phones to the polite guys that show up to work on the system. We have never doubted his opinion. Joe is what we call "old school" meaning he speaks the truth and is dependable. Over the years as Benedetto heating and cooling has grown, he and his team have remained down to earth, he is a good teacher and it shows in his team members. If you have a heating or cooling problem or question, Benedetto H/C is the team you want. Al & Christine Bond. Annie GourlieTrustindex verifies that the original source of the review is Google. Update: We continue to be so very pleased with Benedetto! We upgraded our two boiler systems with Benedetto, and we are very impressed! As we have come to expect from them - all of their service providers are always professional and respectful. They were timely and exceptional at communicating during the install. They left our house spotless, installed a pristine and impressive looking system that is a site to behold! And we believe we got the value for our money. Clay, Rafael, Logan, Ben, Justin and Joe Benedetto himself were polite, considerate and professional during the entire length of the project. I would not hesitate to hire them again and will continue to recommend them! ---------------------------------------- It is rare to find such professionalism in today's market! Both Clayton and Shawn are consumate professionals who respect your home, and provide THOROUGH and EXPERT service! They take the time to educate you, and provide transparent, reasonable quotes prior to doing any work. We have two old Buderus systems, and we've been looking for years to find someone knowledgeable about our systems. They did a complete overhaul to get us functioning properly. And the best part is - I trust them. We will absolutely be loyal customers from here on out! Thanks, Clay and Shawn!
