Expert HVAC Services in Merrimack, NH 03054 - Ac Heating & Air Conditioning

High heating bills in our climate are often due to an aging furnace, insufficient insulation, or air leaks in the ductwork. At AC Heating & Air Conditioning, we start with a thorough energy audit of your Merrimack home. We'll check your system's efficiency, inspect your ducts for leaks, and assess your home's overall heat retention. Our expert technicians can then perform necessary tune-ups, repairs, or recommend system upgrades tailored to New Hampshire winters, helping you save significantly on your energy costs.

If your AC is blowing warm air or icing up, a refrigerant leak is a common culprit here in Merrimack. First, turn the system off to prevent further compressor damage. Call us right away for a professional diagnosis. We use advanced electronic leak detectors to precisely locate even the smallest leaks. Our repair process involves sealing the leak, performing a deep vacuum to remove moisture and air, and then recharging the system with the exact manufacturer-specified amount of refrigerant. This ensures optimal performance, efficiency, and prevents the environmental harm of leaking refrigerants.

Proactive, bi-annual maintenance is the best defense against refrigerant leaks and high energy bills. Our Merrimack-focused maintenance plan includes a spring tune-up for your AC, where we check refrigerant levels and pressure to catch leaks early, clean coils, and ensure electrical components are tight. In the fall, our heating tune-up involves cleaning burners, checking heat exchangers for safety, testing system airflow, and calibrating thermostats. This neighborly service keeps your systems running efficiently, extends their lifespan, and helps you avoid costly emergency repairs during peak seasons.
