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.

FAQs

  • We Install All Types of HVAC Systems

    We worked in many Massachusetts homes over the years, and our experience has shown that every household has unique needs. That’s why our process begins with a free consultation with a project manager to design a customized solution that’s perfect for your home.

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

  • 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.

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.

When my AC quit suddenly, Heritage came in a timely fashion and did an excellent job. The four gentlemen who helped me were professional and knowledgeable. Joe diagnosed the problem and was very thorough in explaining the cost of repair versus replacement. Bobby, Harrison and the electrician Liam did the replacement and were wonderful to work with. They explained the process carefully, answered all my questions and completed the job efficiently and quickly. I would certainly call the company again for any HVAC, plumbing or electrical needs. Thanks Heritage!

First time using Heritage, as two other plumbers I’ve used in the past gave me long lead times. Heritage answered my call personally, and scheduled me same day-amazing considering it was a Saturday! I had a leaking outdoor spigot, and given the drought, waiting a week to fix it was out of the question. The technician sent out, James Shallow, could not have been more professional, knowledgeable and personable. He showed up on time, did the job seamlessly and without issue. He spent time educating us as to how to avoid this problem in the future, and it was a genuinely pleasant experience. I will most definitely use & recommend Heritage again (request Jimmy).

Alex came to fix a water main leak at my home which was pre-manufactured in the late eighties. He found and fixed the leak quickly. After the job was complete I spoke with him about the cause because this is the third time in a year with a leak. He spent the time with me explaining the material used for piping in my place and checked the water pressure. The pressure was on the high end and we both concluded between pressure spikes and old plastic pipes. I asked for an estimate to replace all the pipes. He was able to give me an estimate on the spot and found financing with very reasonable terms. Two days later Heritage Home Services was here with two trucks and completely changed out the piping in a day. In short. This place answers the phone. Gets technician on the job quickly. Great knowledge. Cleaned thoroughly before leaving.

I’ve dealt with Heritage for many years because of their dependability. They are not the cheapest, for sure, but if you need a plumbing or HVAC system installed or serviced/repaired, there’s none better. I needed repairs to be done on slim duct covers that were damaged after having siding installed on my home. I called Heritage because they were the company that installed the original mini-split system in my house several years earlier. John Lindonen and another technician (unfortunately, I don’t remember his name) showed up as committed and did the repair work. They were very thorough, explaining every issue to me and answered all of my questions. They were polite, and extremely knowledgeable. I wouldn’t hesitate to recommend these guys to my family or friends.

The AI interactive was ok but screwed up my ph# so never got a call. However, Camile arrived and spent time discussing my points and activities performed, helped me tremendously and ultimately didn’t need service. He was professional, informative, and transparent so Heritage, please acknowledge his great service!

Frequently Asked Questions

  • How do I know what size air conditioner I need for my Massachusetts home?

    Proper AC sizing depends on your home’s square footage, insulation levels, window exposure, and other factors. Heritage performs a detailed load calculation to recommend the right-sized system, ensuring maximum efficiency and comfort without the energy waste of an oversized or undersized unit.

  • What types of air conditioning systems does Heritage install?

    Heritage installs central air conditioning systems, ductless mini-split systems, and heat pumps from top-rated manufacturers. We help you choose the best option based on your home’s layout, existing infrastructure, and cooling needs.

  • How long does an air conditioning installation take?

    A standard central air conditioning installation is typically completed in one day, usually within four to eight hours. Installations that require new ductwork, electrical upgrades, or other modifications may take an additional day.

  • What SEER rating should I look for in a new air conditioner?

    For Massachusetts, Heritage recommends systems with a SEER2 rating of 16 or higher for the best balance of upfront cost and long-term energy savings. Higher SEER-rated units cost more initially but can significantly reduce your monthly cooling bills over the life of the system.

  • Does Heritage offer financing for air conditioning installation?

    Yes, Heritage offers flexible financing options to help Massachusetts homeowners manage the cost of a new air conditioning system. Contact us to learn about available plans and current promotions that can make upgrading your cooling system more affordable.
