  • Common Causes and Signs That You Need AC Repair

    Our AC units are lifesavers in New Hampshire during those humid summer months. Like any machinery, they wear down from constant use. On top of that, they sometimes get knocked around by ice in the winter or blasted with rocks and debris when we’re tidying up the yard. Any wear and tear can ding up your system and mess with its cooling power.

  • Signs that Your AC Isn’t Working Properly

    Have you ever thought, “Something’s off with my AC, but maybe it’ll sort itself out”? Before your AC gives up on you, here are some tell-tale signs it’s crying out for help:

    • Strange noises coming from your unit? That’s not normal.
    • If the air feels more warm than cool, there’s a problem.
    • Is the AC acting like a light switch, flipping on and off or just refusing to shut down? That’s not a good sign.
    • Do you find yourself playing tag with your thermostat to find that sweet spot of cool? It shouldn’t be that hard.
    • And if you’re still sweating no matter how low you go, it’s time to call in the pros.
  • Causes of Air Conditioning Failure

    We’re no strangers to the quirks of our weather and the toll it takes on our air conditioning systems. Here’s a rundown on common issues that might be messing with your cool summer vibes:

    • Incorrect Thermostat Setting: If your home’s still stuffy despite a running AC, you might’ve accidentally set it to fan-only mode.
    • Refrigerant Leakage: All that use can shake things loose, leading to your cool air making a sneaky getaway.
    • Circuit Breaker Overload: If your AC’s causing the breaker to trip, it’s a sign it’s pulling more power than it should – a nudge that it’s working a bit too hard.
    • Compressor Malfunction: The compressor’s the AC’s beating heart. Trouble with it, whether from power issues, refrigerant woes, or overheating, spells big problems.
    • Coil and Fan Contamination: A layer of grime on these parts forces your AC to overexert itself, dragging down its efficiency.
    • Air Filter Blockage: Not changing your air filter can choke your system, making it cool less efficiently or even freeze.
    • Neglected Maintenance: Annual maintenance can dodge a lot of these AC headaches.
    • System Obsolescence: Sometimes, an old AC just can’t hack the heat anymore. When repairs aren’t enough, it’s time for a new cooling system.
  • AC Maintenance Can Prevent Costly Repairs

    Annual maintenance of your AC system in New Hampshire isn’t just about avoiding the inconvenience of repairs; it’s a strategy to extend the lifespan of your unit and ensure it runs as efficiently as possible. Experts recommend at least yearly maintenance to keep everything in top condition. With Heritage Home Service, you can expect a thorough examination and maintenance of your system, including checking refrigerant levels, cleaning components, and ensuring all parts function correctly. This preventative approach saves you money on potential repairs and ensures your home remains comfortable through the state’s variable climates.

    During an AC maintenance visit from Heritage, homeowners in New Hampshire can anticipate a comprehensive inspection that touches on every aspect of the AC system. From cleaning the air filters to inspecting the ductwork and checking for any operational issues, the service is designed to identify minor issues before they become major problems.

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

  • 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.
