Marlborough – It’s the rare business that provides 24/7 emergency service and has a gorgeous retail showroom. Middlesex Cooling & Heating, a trusted HVAC partner for homeowners and businesses, couples with Energy Unlimited, a purveyor of fine stoves and fireplaces, to form a one-stop shop for cooling and heating service, repair, installation, and purchase.

Winter has arrived early, and heating systems are already being hit hard. Middlesex handles routine and emergency service and repairs for forced-air systems, boilers, heat pumps, furnaces, and more. No homeowner enjoys discovering that the hot water pipes aren’t hot, the thermostat is plummeting, or the forced air isn’t moving. Minor and major repairs are no problem for the folks at Middlesex.

Furnaces, boilers, and hot water tanks can age out, and equipment that’s 20 or more years old isn’t nearly as efficient as the new stuff—it might be time for an upgrade. The pros at Middlesex will provide advice and help homeowners make a smart decision.

It’s cold out there now, but in a few months, thoughts will turn to summer—and air conditioning. Middlesex provides the same great depth of service for cooling systems, from central air and ductless systems to window and free-standing units. Whether it’s routine service, repair, consultation, or an emergency, Middlesex handles it all.

They also specialize in indoor air quality systems like air purifiers, air sanitizers, and whole-home humidifiers. These systems can reduce allergens and contaminants while providing better respiratory health and a more comfortable home.

Middlesex isn’t just for homeowners. They provide commercial HVAC systems and services to companies through the county and beyond, and they service makes and models from all the big names.

They also have a full-service electrical team to handle safety inspections, rewiring, interior and exterior lighting, and emergency power generator installation.

On to Energy Unlimited. Their beautiful showroom is the place to go for wood-burning stoves and inserts, pellet stoves, and gas inserts and free-standing stoves. There are about 25 stoves on display, each with pricing and efficiency information, along with a comfy leather couch to enjoy a fire while reading through product brochures. Energy Unlimited sells and services names like Vermont Castings, Lopi, Morso, RAIS, and Fireplace Xtrordinair.

Striking light fixtures by companies like Kichler and Millennium Lighting adorn the walls and hang from the ceiling—yes, Energy Unlimited sells light fixtures.
