A properly air conditioned home can provide a break from the sweltering New England summers, keeping your family cool and comfortable. To keep everything running correctly, air conditioner maintenance in Southern Maine is the key to a healthy HVAC system.

When the temperature goes up, your air conditioner starts to work harder to cool down and remove moisture from the air. In fact, nearly 80% of system failures happen during the first week of operation. Getting maintenance from a licensed professional can help you reduce the risk of a breakdown in the opening months of summer, which can not only save you money but also potentially prevent an expensive breakdown over the long run.

Heritage Home Service has a dedicated maintenance team serving Southern Maine to help you catch any issues with your air conditioning system before it leaves you hot under the collar.

  • How Often Should I Schedule Air Conditioner Maintenance?

    One of the best investments you can make into your home is annual air conditioner maintenance. In order to keep your warranty valid, most air conditioner unit manufacturers require units to be serviced by a licensed technician once per year. Having an annual maintenance schedule can help you determine the overall health of your unit, including going over the wear and tear from the past year and identifying any potential trouble that could be coming. It isn’t just regular use that can cause air conditioners to fail – manufacturer defects can cause breakdowns early in a unit’s life.

  • Can I Do My Own Air Conditioner Maintenance?

    There are certain easy tasks homeowners can do to ensure their air conditioner stays in top condition. Changing home air filters four times per year and replacing air handler filters every six months can help your air conditioner run well throughout the seasons. When it comes to your outdoor unit, you’ll need some help from a professional.

    Attempting to do your own air conditioner maintenance without any experience or training can do a lot more damage than you may realize. Between hazardous components and high voltage wires, attempting to work on your outdoor unit could be dangerous to your health. In addition, you may also need specialized equipment to make sure everything is working correctly.

    A licensed technician from Heritage is constantly trained on the latest equipment and specifications, ensuring your outdoor unit will get the best service. On an annual air conditioner maintenance call, our professionals will keep you informed at every step and answer any questions you may have during the process. From there, we’ll explain what we did during the maintenance call, and go over any potential repairs you may need in the near future.

  • What Issues Can a Technician Troubleshoot During Air Conditioner Maintenance?

    When it comes to your home systems, knowledge is power. The more you know, the better prepared you are to keep everything running in top shape. Some of the more common issues our technicians see on an annual service call includes:

    • Outdoor unit wiring damage due to rodents
    • Failed fans or a blower motor at the air handler or outdoor unit
    • Burned out capacitor in the outdoor unit
    • Clogs in outdoor coil fins from debris buildup, cutting air flow
    • Outdoor unit coil leaks from damage or normal wear
    • Fallen ice damage to the outdoor unit or coils
    • Clogged condensate line

    While this isn’t the full list of what could happen to your air conditioning unit, these issues are often the ones causing the most problems. With an annual air conditioner maintenance call, our technicians can check to see if these things are affecting your system and make small repairs before they become big problems.

Kyle came by and checked out our AC units l, did a great job very professional and knowledgeable. He even looked at my boiler set up to see about replacing it and messaged a project manager to see about coming out the same day to do a quote. Will be using these folks from now on!

This was our first time using Heritage and it was a great experience. We got an appointment promptly and Bryce and his apprentice arrived right on time. Bryce was a true professional throughout the process. He was troubleshooting a complex whole-house electrical issue for us: he approached it logically, fixed a number of things along the way, kept us updated throughout, explained the issues and our options clearly, and ultimately solved the problem. We will definitely use Heritage again.

Frequently Asked Questions

  • How often should my air conditioner be professionally serviced?

    Heritage recommends professional air conditioning maintenance once per year, ideally in the spring before the cooling season. Annual maintenance keeps your system running efficiently, helps prevent breakdowns during hot weather, and can extend the life of your equipment.

  • What does an air conditioner maintenance visit include?

    A Heritage AC maintenance visit includes cleaning the evaporator and condenser coils, checking and adjusting refrigerant levels, inspecting and tightening electrical connections, testing the thermostat, lubricating moving parts, checking the condensate drain, and evaluating overall system performance.

  • Can AC maintenance lower my energy bills?

    Yes. A well-maintained air conditioner runs more efficiently than a neglected one. Dirty coils, low refrigerant, and worn components force the system to work harder and consume more energy. Annual maintenance helps your AC operate at peak efficiency, which translates to lower monthly cooling costs.

  • What happens if I skip air conditioner maintenance?

    Skipping maintenance can lead to reduced cooling performance, higher energy bills, more frequent breakdowns, shorter equipment lifespan, and potentially void your manufacturer warranty. Many AC warranties require proof of annual professional maintenance to remain valid.

  • Does Heritage offer AC maintenance plans for Maine homeowners?

    Yes. Heritage offers a Home Advantage Membership that includes annual air conditioning and heating maintenance along with benefits such as priority service, repair discounts, and extended warranty coverage. A maintenance plan helps you stay on schedule and save on service costs.
