As New Hampshire residents, we’re lucky enough to experience all four distinct seasons – ranging from bitterly cold winters to hot and humid summers. While we can usually get by with opening the windows during the shoulder months, having an efficient HVAC system is critical to maintaining health and comfort all year round. Luckily, the heating and cooling experts at Heritage can make sure you and your family are comfortable indoors, no matter what mother nature has in store.

Our trusted team of cooling specialists are trained to work on almost all residential AC systems and are backed by a wealth of experience from our 35+ years in the industry. Whether it’s unexpected AC repairs or routine air conditioner maintenance, Heritage has technicians available to help in your area.

FAQs

  • New Hampshire Air Conditioning Maintenance

    • Air conditioning systems break down for a number of reasons, but common issues include:
      • Rodent damage to the wiring of the outdoor condenser
      • Extremely clogged filtration systems
      • Damage to outdoor condenser due to falling ice
      • Debris buildup in outdoor coil fins (often caused by lawnmowers or leaf blowers)
      • Failed capacitor
      • Failed fan motor

    Not sure if your cooling system needs repairs? Some common signs are not enough cool air coming into the home, the outdoor condenser making strange noises, or your system is running constantly but not producing any cool air. Regardless of your exact issue, Heritage is available to help. We’ll diagnose the problem and provide suggested repairs so you have the tools to make the decision right for you and your home.

Mitsubishi Air Conditioners

Don’t have existing ductwork? Ductless air conditioning may be a good option for you! As a Mitsubishi ductless Diamond Dealer, Heritage can expertly design a system unique to your home and needs and can provide you with a number of solutions to bring cooling where you want it. As a bonus, every Mitsubishi ductless unit also functions as a heat pump (essentially an AC system in reverse) during the colder months, and if you upgrade to a Hyper Heat unit, you can heat your home all year round, even down to -13°F.

Called on a Thursday with an active leak…actually a drip…found by luck on the cellar floor. Vinny showed up less than 24 hours later, and after diagnosing the issue found the problem. It wasn’t what I thought, but his perseverance paid big time dividends. On a Friday early evening Vinny made a trip to a Home Depot 30 minutes away, and when he returned the problem was solved in 30 minutes. Heritage upgraded our electrical system from 100 amp to 200 amp, and installed a whole house generator for us during the winter, so we were very familiar with the company. I can’t say enough good things about their workmanship, their customer service, and their professional employees. I would be pleased to have Vinny come back should the need arise. He was great!!
