Over the years, we’ve seen many New Hampshire homeowners upgrade the air conditioning in their homes to escape the heat and humidity. After all, it’s tough to endure the summer with no AC – standing in front of oscillating fans, struggling to sleep, sweating indoors.

If you’re ready for a air conditioner, Heritage’s HVAC team is here to help you find the perfect cooling solution for your home. We offer a wide range of products, and our process is fast and straightforward so that you can have your new AC installed the very next day.

We install all makes and models of residential air conditioning equipment, such as:

Mitsubishi Air Conditioners

As Diamond Dealer in Mitsubishi heat pumps and ductless systems, Heritage highly recommends Mitsubishi mini-split ac systems to New Hampshire 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 it’s time for a new air conditioner, it’s important to work with a highly-qualified, knowledgeable team. Heritage’s HVAC technicians are fully licensed and trained so that your AC installation is completed properly. Our installation process always begins with a free consultation.
During your appointment, an expert will inspect your home and make recommendations based on these factors:

Your current AC system: Most people install the same type of system they had previously, but you may want to consider something new if your current AC is not working for you.

How much and how often you use your AC: If you use your AC all day, every day, we’ll recommend a unit that can handle that 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.

The size of your home: More square footage means you’ll need a larger air conditioner, but we can provide other options, too. You may want separate units for different floors or a ductless AC system so you don’t have to cool the entire house at once.

Ductwork: Roughly one in three houses in New Hampshire were built before 1960, meaning that many homes don’t have existing ductwork. In these cases, we typically recommend ductless AC systems which are much faster and easier to install.

How much you care about energy efficiency: Energy-efficient air conditioners are better for the planet and cheaper to operate. When looking at high-efficiency options, we can calculate how much savings you stand to earn on energy costs.

Budget: We never want cooling your home to be financially stressful. Our team will work with you to find a cooling solution you can afford, or we can direct you to financing options so you can get what you need.

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

We get this question a lot, for good reason! Most people want to keep their air conditioners for as long as possible, but running your system into the ground isn’t always worth it. Here’s what we look for when helping homeowners decide whether to keep or replace their air conditioner.


  • Age of AC unit: 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.
  • Size of current AC: Is your current system 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.
  • 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 you have done several repairs in the last few months, the cost of a replacement may be the best decision for your finances and peace of mind.

Repairing vs. Replacing Your Air Conditioner

There are many AC myths out there, like the idea of needing to “top off” or “recharge” your AC system every year. But here’s the truth: AC systems need all connections and refrigerant lines sealed tight to function properly. Low refrigerant levels usually means there is a leak. While this can sometimes be spot repaired, numerous leaks (especially in critical components like the condenser coil) usually means that it’s time to replace your AC system.

If you find your AC struggling to cool your home or not working as well as before, our licensed HVAC technicians at Heritage can figure out if it needs repair or replacement. Whatever condition your system is in, our technicians will go over all the recommended options with you, so you can make the best choice for your situation.


The Benefits of Installing a New Air Conditioner

  • Higher 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.
