Air Conditioning Services

Whatever service you need for your air conditioner, we can help with all systems including heat pumps, ductless systems, and central AC units. Are you worried about a strange noise coming from the ductwork as you run the unit? We’ll locate the issue and find the proper method of repair for your situation. Worried about the efficiency of the air conditioner? Call and ask about our HVAC maintenance plans to keep your system at peak efficiency. We can also install zone control or a new zone control system. These are just some of the air-conditioning services we offer; call to learn more!

Air Conditioning Repair

We’re used to thinking about air conditioning repair services in the heat of the summer, when your system suddenly breaks down and a technician can’t get to your Cambridge home fast enough. But you can often help out your own cause by planning for repair issues in the fall and spring, before you have need of your air conditioner. Few problems of this nature arise overnight, and if a maintenance session picks up signs of trouble brewing, you can schedule a repair session and get it fixed before you need your system!

Ductless Air Conditioning Advantages

Ductless air conditioning systems have many benefits: superior energy efficiency to many comparable units, built-in zone control, and above-average performance. But perhaps the biggest benefit is that you won’t have to make any major renovations for the unit to be installed. If you’re interested in a ductless air conditioner for your home, get in touch with our cooling specialists.

Heating Services

We install a variety of heating systems, including furnaces (electric, gas, oil, and propane), boilers, heat pumps, ductless heating systems, and radiant systems. To learn more about any one of these options, you should speak with a specialist who can first assess your home and your needs for sizing, efficiency, and fuel type. And whatever type of unit you may currently have, we are able to repair or replace it, or provide maintenance services that can improve efficiency and extend the lifespan of the unit.

Heating Repair and Maintenance

At Cooling Unlimited, Inc., we believe in the swift repair of your system, and our trained team is standing by whenever you need a problem fixed. But we also believe that an ounce of prevention beats a pound of cure, and with regular heater maintenance sessions scheduled for the spring and fall, you’ll be able to stop a lot of serious problems before they start. We serve homes throughout the Cambridge area, and the combination of fast action and timely prevention can make an unbeatable combo for households there!

Gas and Electric Furnaces

You may rely on a gas furnace or an electric furnace variety, depending on the makeup of your Cambridge home and the specific needs of your family. But regardless of what kind of furnace system you have, you want it to function as expected each and every time you turn it on. That means a quality installation from professionals, like the team at Cooling Unlimited, Inc.. We use high-end parts and set up your new furnace with the same care we’d use in our own homes. Call us today to see what kind of a difference we can make.

What’s Wrong with Your Indoor Air Quality?

Are you worried about living microorganisms like bacteria and viruses in the air that could make your family members sick? Are your family members bothered by allergens triggered by dust, pollen, mold spores, and pet dander in the home? Are you uncomfortable in the summer because the air is too humid, or in the winter when the air is too dry? We’ve got a system that can help you recover and feel more comfortable. Our indoor air quality systems, such as our air purifiers, humidifiers, and dehumidifiers, help keep your air healthier and up to your standards. Contact us for more information!

Schedule leak detection services today with our professionals if you want to have your complete plumbing system checked out. And if you are experiencing any trouble with your pipes or fixtures that you can see, we can get to your home for emergency plumbing services or for a scheduled appointment.

Water Heater Services

If you are in need of a new water heater, maybe you have your heart set on a new tankless water heater. Perhaps you are open to exploring other options, like a hybrid water heater or a heat pump water heater. Any of these options can help you to save energy, but a conventional tank water heater might still be the better fit for your needs. Call us today to learn more about any one of these systems and to discover which water heater is right for you. We also repair, replace, and maintain all types of water heaters for homeowners in Cambridge.


In the not-so-distant past, generators were only available for places like hospitals and other properties in which a power outage could be extremely problematic. But today, you can get a generator for any business or residential property. We install and service commercial and residential generators that can restore electrical service to your property within seconds-and you won’t even have to move a finger. Keep your home or business operating all year no matter what with our generator services.

Commercial Services

Our commercial services are extensive, meaning you can make us your one-stop shop for commercial plumbing, commercial HVAC, generators, and indoor air quality systems. From the initial planning process of the plumbing and air ducts in your new construction project to the replacement of a heating system that is decades old, we can rise to the needs of any situation. Call our experts today and learn more about the commercial services that we offer to companies all around the Cambridge, MA area.
