We’re not sure which wise man first said this, but we know it’s true because the tale of DeNardo Heating And Cooling is a love story. We love the constantly evolving HVAC field, we love our family-owned business, and we love providing our extended family — customers in North Shore communities from Everett to Topsfield — with top-quality heating and cooling solutions at a fair price.
Since 2014, our residential HVAC company has been specializing in sales, service, installation, repairs, and preventive maintenance for central ducted heat pumps, mini splits, water heaters, and gas and oil boilers. We offer financing, too. We provide 24-hour emergency service to restore your comfort level when your heat or air conditioning malfunctions at the worst possible time.
We pride ourselves on offering green and high-energy efficiency solutions and upgrades, and we love to help you save money. As part of the Mass Save heat pump installer network and the Wakefield, Reading, and Peabody Municipal electric companies’ rebate programs, we can help you obtain all the incentives and rebates you deserve for going green.

100+ five-star reviews across Google & Yelp — here’s what a few neighbors had to say.
★★★★★ Rated 5.0 across Google & Yelp • BBB A+ Accredited Quality
We emphasize education because we want to keep up with the latest, greatest technologies while still being able to service the oldest heating equipment still in use in the area. We are a Fujitsu Elite Contractor, and we have technicians who are factory trained by Fujitsu, Bosch, Trane, and Mitsubishi for heat pumps and air conditioning, as well as Lochinvar, Carlin, Beckett, and Riello for boilers. Education continues after hours, too.
We do our best to keep up with system, product, and industry changes, like what it means to our work when a new refrigerant comes on the market. Owner Gaetano DeNardo, a true HVAC nerd with 20 years in the field, reads code books for fun because he notices that some inspectors don’t understand the intricacies of HVAC and boiler systems and wants to make sure his team does it right the first time.
We stand behind our work, providing a 100% satisfaction guarantee for a full year on parts and labor. We’re not happy unless you’re happy!
