  • 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.

We called Heritage when our condenser failed. They were the first company we thought of. We called Sunday night and the automated system was able to secure us an appointment for Tuesday. Angel was the tech and he was amazingly helpful, professional and thorough. He provided us with three options for how to proceed. And he was able to secure us an appointment with the new installation team for Wednesday morning. Everyone communicated with us each step of the way – were exceedingly knowledgeable and professional. Service was top notch!

I might have a new favorite home service company. Heritage knows their stuff. They installed a new electrical panel, and adapted well to minor challenges during install. They even took the time to do a the load calculations for future HVAC, rather than just tell me to upgrade my underground electrical service. Another company attempted rewiring my stove outlet and left without testing it. Looking forward to more work with Heritage

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.
