A crucial part of making sure you and your family keep cool all summer long is maintenance. In New Hampshire, we can experience very hot summers which put a lot of stress on your air conditioning system. With around 80% of failures occurring during the first week of operation, calling in a licensed professional to perform routine maintenance before or right after each season can save you a lot of money and headaches in the long run.

This is why Heritage Home Service created a dedicated maintenance team to serve our customers and help catch issues before they become larger problems.

FAQs

  • Air Conditioner Maintenance Services in New Hampshire

    How Often Do Air Conditioners Need Maintenance?

    We can’t stress enough how important it is to have routine maintenance each year. Not only do most air conditioning manufacturers require this to maintain their warranty, but your air conditioning unit is a piece of mechanical equipment, and wear and tear each season should be addressed to make sure you’re good to go. We often hear customers say their system was only installed within the last few years. While it’s true your typical wear and tear issues are less likely to occur, the reality is that manufacturer defects, while uncommon, can crop up in this time.

    And just like your car needs routine service at certain mileage markers, so does your AC system. It’s not uncommon to see certain parts reach their life expectancy within just a few years of use.

  • Should You Perform Air Conditioner Maintenance Yourself?

    We always encourage homeowners to take control over their equipment and perform basic maintenance when possible. Things like replacing filters at the air handler is a routine task that should be done every 6 months or sooner. When dealing with your outdoor unit, it’s always best to seek a licensed HVAC technician for help.

    Not only can some components that make up your air conditioner be dangerous if not handled properly, but some specialty equipment such as AC gauges are required to perform a complete maintenance.

    When you choose Heritage, you can rest assured that we’ll include you in the process of everything we go through and provide a comprehensive report on any issues we came across during our visit. We’ll also present you with options for repair as necessary so you can make the best choice for your home.

  • What Problems Are Found During Air Conditioner Maintenance?

    Whether potential issues facing your air conditioner are minor or serious, we want you to feel empowered with the knowledge of what exactly is going on with the equipment in your home. Some common problems we come across are:

    • Rodent damage to wiring in the outdoor unit
    • Failed fan/blower motor at the air handler or outdoor unit
    • Fail capacitor in the outdoor unit
    • Debris build-up in outdoor coil fins restricting airflow
    • Leaking outdoor coil due to damage or wear and tear
    • Damage to the outdoor unit due to fallen ice
    • Clogged condensate line

    While not meant to be exhaustive, if you’re experiencing any of these issues, our AC repair services team can diagnose and resolve them quickly. With annual maintenance, your chance of an unexpected breakdown occurring due to these issues can be greatly reduced.

  • How much does AC maintenance cost in New Hampshire?

    A standard AC maintenance in New Hampshire from Heritage costs $223–$298 depending on system type and condition. Heritage Home Service provides upfront pricing with no hidden fees. Maintenance plan members receive discounted rates plus priority scheduling and repair discounts.

  • What does a Heritage AC maintenance include?

    A Heritage AC maintenance includes a comprehensive multi-point inspection: thermostat calibration, air filter replacement, refrigerant level check, condenser coil cleaning, electrical connection inspection, motor lubrication, drain line clearing, and system performance measurement. Our licensed technicians check every critical component.

  • How often should I schedule AC maintenance in New Hampshire?

    Schedule your AC maintenance once per year, ideally in spring before summer temperatures arrive in New Hampshire. Annual maintenance prevents unexpected breakdowns, improves energy efficiency, and is often required to maintain your manufacturer’s warranty.

  • What are signs my air conditioner needs maintenance?

    Common signs include rising energy bills, uneven cooling between rooms, unusual noises or odors, the system cycling on and off frequently, weak airflow from vents, and moisture or ice forming on the unit. If you notice these in your NH home, schedule a maintenance before the issue leads to a costly repair.

  • When is the best time to schedule AC maintenance in NH?

    The best time to schedule AC maintenance in New Hampshire is between March and May, before summer heat and humidity arrive. Scheduling early ensures your system is ready for peak demand. Heritage offers flexible scheduling including evenings and weekends.

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!
