Tonawanda, NY HVAC Services

Emerald Heating and Cooling is a family-owned HVAC company founded in 2000 by Marty and Carrie Sheehan. The company has grown almost entirely through word-of-mouth referrals from satisfied customers throughout Western New York — including Tonawanda and the surrounding Niagara and Erie County communities.

Our maintenance visits cover the full system — cleaning, inspection, safety checks, airflow testing, electrical component testing, thermostat calibration, and a full performance assessment. If we find anything that needs attention, we’ll explain it clearly and give you upfront pricing before doing anything about it.

Lucky Ducks Club members receive priority scheduling, which puts them at the front of the line when their heating or cooling system is down. Members also pay no weekend or overtime charges — which matters when your system fails at 9 p.m. on a Saturday in January.

Yes. Our technicians work on furnaces (gas, electric, oil, and high-efficiency condensing), boilers (gas, oil, steam, hydronic, combi, and high-efficiency), heat pumps, and all other residential heating equipment. We also service and replace water heaters.

That depends on the age of the system, the nature of the problem, and how much the repair would cost compared to replacement. We’ll give you a straight, honest assessment — and we won’t push you toward replacement if repair genuinely makes more sense.

Yes. We install and service whole-home air filtration, UV air purification, and humidity control equipment. If dust, allergens, dry air in winter, or excess moisture in summer has been affecting your home’s comfort, we can help you find the right solution.
