Heating Services in New Hampshire

A working heating system is essential when temperatures fall below freezing. Heritage provides heating services for furnaces, boilers, heat pumps, ductless systems, and other residential equipment.

Homeowners can get help with heating repairs, new equipment, routine maintenance, and problems such as uneven temperatures or a system that struggles to keep the house warm.

Furnace Repair

A furnace that stops heating, makes new noises, or runs without bringing the house up to temperature needs professional attention. Heritage provides furnace repair for common problems involving ignition, airflow, controls, electrical components, and other parts of the system.

A diagnostic visit can identify the cause and help you decide on the next step.

Furnace Installation

An older furnace may eventually reach a point where continued repairs no longer make sense. Heritage provides furnace installation and replacement for New Hampshire homeowners who need a new heating system.

Choosing a furnace involves more than replacing the old unit with equipment of the same size. Home size, insulation, ductwork, fuel type, and heating needs all affect the right choice.

Boiler Repair

Boilers remain common in New Hampshire homes, especially properties with hot water baseboard heating. Heritage provides boiler repair for systems that are not producing enough heat, making unusual noises, leaking, or showing other signs of trouble.

A licensed HVAC professional can diagnose the system and explain the repair options.

Boiler Installation

Heritage installs replacement boilers for homeowners with aging or failing equipment. The installation process includes evaluating the home’s heating needs and selecting equipment suited to the existing system.

Professional installation also helps make sure the boiler is properly connected, set up, and tested before it begins regular operation.

Heating Maintenance

Annual heating maintenance gives a technician an opportunity to check the system before winter places heavier demands on it. Heritage recommends routine maintenance and notes that annual service may also be required to maintain some manufacturer warranties.

Maintenance can help identify worn components, performance problems, and other concerns before a heating breakdown happens during a New Hampshire cold snap.

Humidifiers and Dehumidifiers

Indoor humidity can affect how comfortable your home feels throughout the year. Winter heating can leave indoor air feeling very dry, while warmer months can bring excess humidity.

Whole-home humidification and dehumidification equipment can help homeowners manage moisture levels as part of their overall comfort system.

Cooling Services in New Hampshire

Hot, humid summer weather can put significant demand on residential cooling equipment. Heritage provides cooling services for central air conditioners, ductless mini-splits, heat pumps, and other home comfort systems.

Cooling service includes repair, installation, maintenance, and additional solutions for homeowners who need better temperature control or indoor comfort.

Air Conditioner Repair

An air conditioner can fail for many reasons, including electrical component problems, damaged condenser equipment, clogged filtration, debris buildup, failed capacitors, and fan motor problems.

Signs that your AC may need repair include:

A professional diagnosis can pinpoint the problem before you decide on a repair.

Air Conditioning Installation

Heritage provides air conditioning installation for central AC and ductless systems throughout New Hampshire. Proper sizing is important because the home’s square footage, insulation, existing infrastructure, and cooling needs all affect equipment selection.

Installation may be appropriate when an older system needs frequent repairs, struggles to cool the house, or no longer fits the homeowner’s comfort needs.

Air Conditioner Maintenance

Routine AC maintenance helps prepare cooling equipment for periods of heavy summer use. A technician can check the system, identify potential problems, and make sure key components are ready for warmer weather.

Scheduling service before the hottest part of summer can also give homeowners time to address problems before they need the system every day. Heritage recommends annual cooling maintenance and notes that it can help maintain manufacturer warranty requirements.

Ductless Mini-Split Repair

Ductless mini-splits provide heating and cooling without traditional ductwork. They can be a good fit for older New Hampshire homes, additions, finished basements, garages, and other spaces that are difficult to connect to a central duct system.

Heritage services ductless systems that are not heating or cooling correctly, have airflow problems, make unusual noises, or show other signs that something is wrong.

Ductless Mini-Split Installation

A ductless mini-split can provide targeted comfort without installing a complete duct system. Individual indoor units also allow homeowners to control temperatures in specific areas.

Heritage is a Mitsubishi Diamond Dealer and installs Mitsubishi ductless systems in New Hampshire. Mitsubishi mini-splits can provide cooling and heat pump operation, making them useful through more than one season.

Duct Cleaning

Dust and debris can collect inside ductwork over time. Duct cleaning can help remove buildup from the system and may be useful after certain renovations, contamination concerns, or when ducts have accumulated significant debris.

Ductwork should also be checked when airflow problems affect several areas of the house, since the cause may involve more than the heating or cooling equipment itself.

Indoor Air Quality

Temperature is only one part of home comfort. Humidity, airborne particles, filtration, and ventilation can also affect how indoor air feels.

Heritage provides indoor air quality solutions for New Hampshire homeowners who want to address concerns beyond basic heating and cooling.

Smart Thermostat Services

Smart thermostats give homeowners more control over heating and cooling schedules and settings. Depending on the equipment, they can provide remote controls, scheduling features, and information about HVAC use.

Compatibility depends on both the thermostat and the heating or cooling system, so professional installation can help make sure the equipment works together correctly.

Heating and Cooling Help Across New Hampshire

Heritage has served New England homeowners for more than 35 years and provides HVAC service through licensed and certified professionals. Technicians receive training on common and less common residential heating and cooling equipment through the Heritage Training Academy.

Service is available across Heritage’s New Hampshire coverage area, helping homeowners prepare for freezing winter weather, summer heat, and the changing conditions between seasons.

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.

We called several plumbers and I got “we are too busy” and “it’s too small of a job”. Not with heritage though! They were able to get us on the schedule in a timely manner and helped us with our plumbing issue. Thank you Zach! Zach was quick and professional! Will definitely use again!

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

  • What are common signs my air conditioner needs repair?

    Common signs include warm air blowing from the vents, weak airflow, unusual grinding or squealing noises, frequent cycling on and off, water leaks around the unit, or a noticeable increase in your electric bill. If you experience any of these, contact Heritage for a diagnosis.

  • Does Heritage repair all brands of air conditioners?

    Yes, Heritage technicians are trained and equipped to repair all major air conditioner brands and models, including central air systems, heat pumps, and ductless units. We carry common parts on our trucks to complete many repairs in a single visit.

  • How much does air conditioner repair cost in New Hampshire?

    Repair costs depend on the nature of the problem, ranging from simple fixes like a capacitor replacement to more involved repairs like a compressor or refrigerant leak fix. Heritage provides an upfront diagnosis and transparent pricing before beginning any work.

  • Should I repair or replace my air conditioner?

    If your AC is over 10 to 15 years old, uses R-22 refrigerant, or the repair cost is more than half the price of a new system, replacement is usually the smarter financial choice. Heritage can help you evaluate your options and recommend the most cost-effective path forward.

  • How can I prevent air conditioner breakdowns?

    Regular maintenance is the best prevention, including changing filters monthly during cooling season, keeping the outdoor unit clear of debris, and scheduling annual professional maintenance. Heritage offers maintenance services to keep your system running reliably through New Hampshire’s summers.
