Best Air Conditioning & Heating Companies in Rochester

If your furnace seems to run without end but the second floor stays chilly, it may be struggling with our extreme 6,600 HDD heating demand. Many homes built before 1970 have gravity-fed ductwork or older configurations meant for coal or oil, which often leave modern gas furnaces unable to distribute heat during a sub-zero lake-effect cold snap. Another red flag is a system that frequent cycles or makes a metallic bang upon startup; this often points to a cracked heat exchanger in an aging unit, a common safety risk in our area where systems work hard for six months straight. Finally, pay attention to high indoor humidity during the summer. If your AC is cooling but the air feels damp, the unit may be oversized—a common issue in older Rochester neighborhoods like South Wedge where insulation is minimal and systems were retrofitted without proper load calculations.

Before you call for service, head outside and inspect your intake and exhaust vents. During our persistent 100-inch snow seasons, lake-effect drifts can easily block these pipes, causing your furnace to shut down for safety. Another common winter issue is a frozen condensate line; if your high-efficiency unit is draining to an exterior wall, ice can back up the system. In the summer, check your outdoor condenser for cottonwood seeds or grass clippings. Our spring blooms can mat against the coils like a blanket, causing the system to overheat during our humid 80-degree July weeks. If your system is over 15 years old and still running on R-22 refrigerant, check NYSERDA or RG&E guidelines for current heat pump conversion rebates before approving a costly repair. However, if you detect the smell of rotten eggs, see orange flames in your burner, or hear buzzing from your electrical panel, stop immediately and call a certified HVAC company.

In a climate where 60% of our housing stock predates 1970, maintenance and conversion are the primary focuses for local technicians. Steam and hot water boiler repair is essential for many of our historic Corn Hill and Park Avenue homes, as these aging hydronic systems frequently develop leaks or air-locks that prevent heat from reaching every radiator. For suburban properties built in the 1950s–70s, furnace modernization is common; upgrading from an 80% to a 95+ AFUE model significantly reduces Rochester Gas & Electric bills during our 145-day freeze season. We also see high demand for whole-home humidification. Because our winter air is so cold and dry, properly integrated humidifiers prevent wood flooring from cracking and improve comfort in drafty historic homes. Finally, cold-climate heat pump conversions are surging thanks to NYSERDA incentives, allowing homeowners to replace aging oil or gas systems with equipment designed to maintain efficiency even when temperatures drop to zero.

To find the best HVAC companies in the region, start by verifying that their technicians hold NATE certification and the federally required EPA 608 certification for refrigerant handling. Because New York state has specific licensing requirements for plumbing and mechanical work, you should also ensure the company carries comprehensive general liability insurance and workers’ compensation. Real local expertise means the contractor is well-versed in the NYSERDA Clean Heat program and can help you navigate local RG&E energy efficiency rebates. At a minimum, they should understand how to properly insulate and vent an attic to prevent the chronic ice damming common in our lake-effect snow belt.
