McGarvey Refrigeration & Heating - Alliance's Best HVAC Services

Common signs in our area include uneven heating or cooling between rooms, unusually high energy bills, excessive dust in your home, and whistling sounds from your ductwork. Our technicians perform a thorough diagnostic, often using specialized tools to measure airflow and pinpoint leaks, so you know exactly where your system is losing efficiency and money.

Professional duct sealing involves locating all leaks in your duct system—often in attics, basements, or crawlspaces—and sealing them with durable, UL-approved mastics or metal-backed tapes. For Alliance homes, this service is crucial. It stops conditioned air from escaping into unused spaces, which directly improves comfort, reduces strain on your HVAC unit, and can lower those high energy bills by improving system efficiency by 20% or more.

Absolutely. Modern, high-efficiency HVAC systems are engineered for climates like ours, with variable-speed motors and advanced compressors that use significantly less energy to heat and cool your home. By replacing an old, inefficient system, Alliance homeowners often see a dramatic reduction in their monthly bills. We can help you select the right system with a favorable SEER and HSPF rating to maximize your savings year-round.
