FAQs

  • Common Causes and Signs That You Need AC Repair

    We rely heavily on our air conditioning in Maine to combat the summer heat. These systems aren’t immune to the usual wear and tear, nor are they safe from nature’s curveballs, like stray debris kicked up by lawnmowers. These external factors can increase, decreasing efficiency and performance hiccups in our AC units.

  • Signs that Your AC Isn’t Working Properly

    In Maine, we’re no strangers to doing a bit of troubleshooting around the house. Some issues are your cue to call in Heritage. If any of these signs sound familiar, it might be time for a check-up:

    • New, odd sounds from your AC? That’s your first red flag.
    • Is the air coming out warm instead of refreshingly cool? That’s a no-go.
    • Your AC has a mind of its own, shutting off or blasting non-stop? Time for a look.
    • Constantly nudging your thermostat without getting cooler? Something’s up.
    • If your home feels like a sauna no matter what, don’t ignore it.
  • Causes of Air Conditioning Failure

    We understand the importance of a reliable AC during those brief but intense summer months. Below are some common issues that might be preventing your air conditioner from providing the relief you need:

    • Thermostat Settings: If it feels like your AC is ignoring you, double-check that it’s not just set to “fan” mode instead of cooling.
    • Refrigerant Leaks: Frequent use can wiggle connections loose, letting your cool air literally escape into thin air.
    • Tripping Breakers: ACs can be power hogs, occasionally overloading circuits. It’s a sign your unit is pushing its limits.
    • Compressor Failure: Consider the compressor the heart of your AC. Issues with power, refrigerant, or just old-fashioned overheating can cause it to flatline.
    • Dirty Coils/Fan Blades: Dirt buildup here means your AC has to work harder to keep you cool, slashing efficiency.
    • Clogged Air Filters: A dirty filter can strangle your system, leading to slow cooling or even a total freeze-up.
    • Skipping Maintenance: Regular check-ups can prevent these common culprits of AC troubles.
    • Time for an Upgrade: When your AC is more ancient than efficient, no amount of repairs will save it from the summer heat. Time for a new one!
  • AC Maintenance Can Prevent Costly Repairs

    In Maine, where the summers can be surprisingly warm, ensuring your air conditioning system is in prime condition is crucial for comfort. An annual maintenance check is the key to detecting and addressing wear and tear early on. Heritage Home Service offers AC maintenance services that improve your AC’s performance and contribute to its longevity. Our experts perform detailed inspections and adjustments, ensuring that every component of your system is operating at its best.

    A typical maintenance visit involves a series of checks and cleanings, from evaluating the thermostat settings and electrical connections to cleaning the evaporator and condenser coils. Heritage’s technicians are thorough, focusing on optimizing airflow and cooling efficiency. This means a reliable AC system that’s less likely to break down during the hot months, ensuring your home stays comfortable no matter the weather outside.

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 the signs my air conditioner needs repair?

    Common signs include warm air blowing from vents, weak airflow, unusual noises like grinding or squealing, frequent cycling on and off, water leaking near the unit, unpleasant odors when the AC runs, and higher-than-normal energy bills. If you notice any of these, contact Heritage to schedule a repair.

  • Why is my AC blowing warm air?

    An air conditioner blowing warm air can be caused by low refrigerant, a dirty air filter restricting airflow, a frozen evaporator coil, a malfunctioning compressor, or a thermostat set incorrectly. Heritage can diagnose the specific cause and perform the necessary repair to restore cool air.

  • Does Heritage offer same-day AC repair in Maine?

    Heritage works to accommodate urgent AC repair requests as quickly as possible. If your air conditioning fails during hot weather, contact us and we will schedule a service call at the earliest available time to restore comfort to your home.

  • Should I repair or replace my air conditioner?

    If your AC is less than 10 years old and the repair is straightforward, repair is usually the better choice. If the unit is older, uses R-22 refrigerant, requires a major component replacement, or has needed multiple repairs recently, replacement may be more cost-effective. Heritage provides honest recommendations based on your system’s age and condition.

  • Can regular maintenance prevent AC repairs?

    Yes. Annual professional maintenance catches many issues before they become costly repairs. Clean coils, proper refrigerant levels, and tight electrical connections all reduce strain on the system. Heritage recommends scheduling a maintenance visit each spring to keep your AC in peak condition and reduce the likelihood of breakdowns.
