Why Does AC Sizing Matter?

Air conditioners are not chosen based only on the square footage of a house. Several parts of the home affect how much cooling it needs.

An HVAC professional may consider:

An oversized AC can reach the thermostat setting too quickly and shut off before removing enough indoor humidity. An undersized unit may run for long periods and still struggle to cool the home.

New Hampshire’s summer humidity makes proper sizing particularly important. The goal is to install equipment that can maintain both comfortable temperatures and appropriate moisture levels.

FAQs

  • How do I know what size air conditioner my home needs?

    System size depends on more than square footage. Insulation, layout, windows, sun exposure, ductwork, and other factors can affect cooling needs. A professional assessment helps determine the appropriate capacity for your home.

  • Can I replace only the outdoor AC unit?

    It depends on your existing HVAC equipment and the compatibility of the components. Indoor and outdoor equipment are designed to work together, so an HVAC professional should evaluate the complete system before recommending a partial replacement.

  • How long does an air conditioner installation take?

    Installation time varies based on the home, equipment, and amount of work required. Replacing an existing system may be more straightforward than adding central AC to a home that does not already have the necessary infrastructure.

  • Should I replace my furnace when I replace my AC?

    Not automatically. The age, condition, compatibility, and expected service life of both systems should be considered. If both pieces of equipment are aging, discussing them together may help you plan future HVAC work.

  • When is the best time to install a new AC?

    You can replace an air conditioner whenever the existing system no longer meets your needs. Planning replacement before the hottest part of summer can reduce the chance of being without cooling during a heat wave.

We worked with James and if possible we will be requesting he come back for future visits! The service was amazing, the price was reasonable, and scheduling was super easy.

I can’t say enough good things about this company, they’ll definitely be our go to moving forward.

James was fantastic with all the work he did on our house. We had him and Carter (who was also amazing) install some lights in our 1870s farmhouse. They started with the work downstairs which was adding in new lights in the kitchen, living room, and our bedroom downstairs. On top of the light additions they also fixed some other electrical issues we found during inspection and they installed new smoke and CO detectors. The work was amazing. We then had James and Carter come back to install lights in the 4 bedrooms upstairs. 2 of those bedrooms had never had lights before. They did a fantastic job. Highly recommend them to anyone. They respond very fast and the turnaround time is amazing.

Alex is a true professional! He diagnosed my problem with my Bosch Furnace and fixed. Additionally, he found dirty flame rod and coil that Pine State Services supposedly cleaned in the annual service in June, however, since it had not run since then I have serious questions about that “service”. Highly recommend Heritage Home Service and Alex!

Jimmy was on time, explained everything clearly, advised me about best practices with the system, what to look out for, explained how my system was looking, and got it done well. Refreshingly awesome to have someone enter your home who only wants to do good work, treat people well, and be treated the same. I hope Gelinas is doing well by this guy, the combi-boiler guru.

Our kitchen sink began to leak all under the cabinet last night. We got it cleaned up enough to be okay through the night, but as soon as morning came around, we knew we would need a plumber ASAP. So, we looked up plumbers in our area on Angi. Heritage was the first listing that came up. They answered the phone on the first ring, and before we knew it, Noah was at our house. We were amazed at how quickly we were able to get an appointment. He was knowledgeable, very polite and friendly, and he worked quickly and efficiently. He was everything we could hope for. Our new kitchen faucet is beautiful, nothing leaks in the cabinet underneath, and he even fixed our bathroom toilet lickety-split, too. Even better, we were able to schedule Heritage to come tomorrow to look at an outdoor outlet that we’re having trouble with. We are so pleased with everything. We would highly recommend this company to anyone in need of a plumber or the other services Heritage provides. Thank you, Noah, and thank you, Heritage!

Technician George Fiske instructed us on all the things we needed to know about maintenance and functioning of the new to us gas furnace (which is located in the attic). We just moved into this condo and needed this guidance….he also did the same with our central AC, hot water heater and even our Nest thermostat! Very very helpful and George was terrific. Will call Heritage for the plumbing issues we need to address also!

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.
