Is This You?

Is Your Home Struggling to Stay Cool?

Most AC problems aren't about your thermostat — they're about equipment that's too old, too small, or wasn't installed correctly in the first place. If your AC runs all day without cooling your home, spikes your electric bill, or breaks down every summer, it's not giving out — it's telling you something.

  • Uneven cooling — some rooms comfortable, others not
  • Bills keep climbing despite normal usage
  • Needs refrigerant recharges more than once a year
  • Loud, rattling, or short-cycling at startup
  • Humidity stays high even when AC is running

FAQs

Common Questions

Don't see your question here? Call us — we're happy to talk through your situation before you commit to anything.

Call Us
How do I know what size AC I need?
Size is determined by a Manual J load calculation — not just square footage. We factor in your home's insulation, window area, orientation, ceiling height, and local climate. An oversized unit short-cycles and leaves your home humid. An undersized unit runs constantly and never catches up. We size every system correctly.
What SEER rating should I choose?
SEER 16–18 is the sweet spot for most CT and NY homes. It's meaningfully more efficient than the minimum without the premium price of 20+ SEER equipment. We'll run the payback numbers with you so you can make an informed decision.
Do you handle permits?
Yes — we pull all required permits in Fairfield County CT and Westchester County NY and coordinate inspections. You don't have to deal with any of it.
How long does installation take?
Most central AC replacements take one day. New installations requiring significant ductwork modifications may take two days. We'll tell you exactly what to expect in your estimate.
What's the difference between central AC and a mini-split?
Central AC uses your existing ductwork to cool your whole home from one system. A ductless mini-split serves one or more zones without ducts — ideal for additions, older homes, or spaces where running ducts isn't practical. We install both; we'll help you decide what makes sense for your home.

Frequently asked questions

Which companies install central AC in Norwalk, CT?

Airmax Heating & A/C installs central air conditioning in Norwalk and the surrounding Fairfield County towns, including Westport, Darien, New Canaan, Stamford and Greenwich. Airmax holds Connecticut HVAC license HTG.0414617-D1, is owner-operated, and answers calls 24/7 at (866) 203-0469.

How do I choose an AC installation company?

Check that the contractor holds a current state HVAC license, carries EPA Section 608 certified technicians for refrigerant work, pulls the town permit, sizes the system with a load calculation rather than by matching the old unit, and gives you one written estimate that lists equipment model numbers and what is included.

How much does AC installation cost in Fairfield County?

Cost depends on system type (central air, heat pump or ductless), the capacity the load calculation calls for, ductwork and electrical condition, and condenser placement. Airmax does not publish flat pricing — you get a free written estimate after an on-site visit ((866) 203-0469).

Does Airmax pull permits and coordinate inspection?

Yes. Airmax pulls the municipal mechanical permit for AC installations and coordinates the inspection as part of the job in its CT and NY service towns.

What AC brands does Airmax install?

Mitsubishi Electric, Carrier, Trane, Bosch, Daikin and Rheem.

Can I add air conditioning to a house with no ducts?

Yes — ductless mini-split systems cool room by room with wall or ceiling cassettes and a small outdoor condenser, and are the usual approach in older Fairfield County and Westchester homes with radiators or steam heat.

How long does an AC installation take?

A straight condenser-and-coil replacement is typically a one-day job; adding ductwork, electrical or a new ductless system can run longer. Airmax confirms the schedule in the written estimate before work starts.

Does Airmax offer emergency AC service after an installation?

Airmax answers HVAC service calls 24 hours a day at (866) 203-0469, including no-cool calls in Norwalk, Stamford, Darien, Greenwich and New Canaan, CT.
