Massachusetts experiences all four seasons, including hot and humid heatwaves. Even in older homes without ducts, more households are installing new air conditioners to stay cool.

Whether it’s a replacement or a first-time installation, our customers value having a comfortable home when temperatures rise above 90 degrees. We all understand the struggle of enduring a hot summer day without AC—relying on fans, struggling to sleep, and sweating indoors. Not our idea of a good time.

If you’re ready for a new air conditioner or need to replace your old one, our dedicated HVAC team is here to help. We offer a range of options to fit any budget, and our installation process is quick and easy, allowing you to have your new AC installed as soon as the next day.

Heritage services all makes and models of residential air conditioning equipment, such as:


Ductless Air Conditioners by Mitsubishi

Roughly 58% of housing units in Massachusetts use an individual air conditioning unit such as a ductless mini split. As Diamond Dealer in Mitsubishi heat pumps and ductless systems, Heritage highly recommends Mitsubishi mini-split ac systems to Massachusetts customers who don’t have existing ductwork. With premium build quality and performance, a Mitsubishi system can bring the same functionality of central air conditioning to almost any existing home. They’re also great for additions and finished, detached spaces.

Choosing the Right Air Conditioner for Your Home

When time comes for a new air conditioner, working with a highly-qualified, knowledgeable team is critical. Our process always begins with a free consultation. During your appointment, we will inspect your home and go over the factors that determine which AC will best fit your needs:

Your current AC system: Most people opt to replace their old AC with the same type of system, but you may want something new if your current air conditioner is not working well for you.

The size of your home: More square footage means you’ll need a larger air conditioner, but we can provide other options, too. You might want separate units for different floors or a ductless mini-split system for zoning.

How often you use your AC: If you have the AC running all day, every day in the summer, we’ll recommend a system that can handle the workload. If you only use your AC sporadically, we can offer other solutions that may cost less and still keep you cool when you need it.

Ductwork: Central air conditioning requires ductwork throughout your home. Massachusetts has some of the oldest houses in America (including the oldest home, built in 1640), so plenty of homes don’t already have ductwork. This makes ductless AC options the better choice because they are more versatile and easy to install.

How much you care about energy efficiency: High-efficiency air conditioners are better for the planet and can even save you money on energy bills. When looking at high-efficiency options, we can calculate how much savings you stand to earn.

Your budget: We never want cooling your home to be financially stressful for you. Our techs will work with you to find you an AC solution you can afford. We can also direct you to financing options so you can get what you need.

How Do I Know if My AC Needs to Be Replaced?

Even with proper maintenance, all good air conditioners must meet their end. Components will inevitably wear out, leaks will occur, and performance will decline enough to make AC replacement a more economical choice in the long run.

Here are the factors we look for when helping Massachusetts homeowners decide whether to keep or replace their air conditioner.


  • Age of AC system: Most units are designed to last somewhere between 10 and 20 years. If yours is within this age range, it’s time to start thinking about a replacement. We can test it to see how well it’s working, then talk to you about your best options.
  • Performance decline: Over time, air conditioners lose their ability to efficiently keep your home cool. Air conditioners that don’t receive yearly maintenance tend to malfunction more often, increase your energy bill, and need replacing sooner.
  • Cost and frequency of repairs: Sometimes repairs actually cost more than a new unit would. Other times, small repairs start to add up. If your AC is in need of repair or has had several repairs in the last few years, the cost of a replacement may be a better deal.
  • Size of current AC: Is your current AC the right size for your home? If it’s too big or too small, it won’t work the way you need it to. Replacement is usually the best option.

Should I Repair or Replace my AC?

Typically, worn-out parts and small leaks can be fixed without issues. But as your system ages, compounding issues will compromise the integrity of your system and make repairs too costly to be worthwhile.

If you notice your unit leaking refrigerant, making strange sounds, or not cooling as well as it used to, Heritage’s licensed HVAC technicians can diagnose the problem and determine whether repair or replacement is necessary. Regardless of what condition your AC is in, our technicians provide all the recommended options during each service visit so that you have the tools to make smart decisions for your family.


The Benefits of Replacing Your Air Conditioner

When your old AC gets past a certain age, a decline in performance is inevitable. Replacing it with a new system provides the following benefits:

  • Better Energy Efficiency: When you’ve had the same air conditioner for 10-20 years, installing a new model can be a huge improvement! Air conditioners manufactured now are more energy-efficient than ever before, which is better for the planet and your energy bill.
  • Better Performance: In addition to monthly savings on your energy bill, a new air conditioner will save you from the stress and cost of unexpected repair calls. With annual maintenance, your new air conditioner should be run without problems for many years.
  • Improved Air Quality: Your air conditioner doesn’t just keep your home cool – it also removes humidity, provides ventilation, and helps filter the air. Your new AC can also be installed with IAQ products such as UV lamps and whole-home dehumidifiers.
  • Smart Home Integrations: If convenience is important to you, you have the opportunity to install a smart thermostat or zoning system along with your new AC. These upgrades enhance the convenience and personalization of your HVAC system to maximize home comfort.
  • Rebates & Tax Credits: When you purchase a high-efficiency HVAC system, water heater, or electrical upgrade, you could save thousands of dollars in tax credits and rebates. Just ask us which products qualify, and we can help you take advantage of these programs.
