Delta Mechanical - Hooksett's Trusted HVAC Repair

Common signs include your AC blowing warm air, ice on the refrigerant lines, a hissing sound, or a sudden spike in energy bills. For Hooksett homeowners, we first use electronic leak detectors to pinpoint the exact location. We then repair the leak, perform a system evacuation to remove moisture and air, and recharge it with the precise amount of refrigerant specified by the manufacturer, ensuring optimal efficiency and cooling power.

A crack in your furnace's heat exchanger can allow carbon monoxide—an odorless, dangerous gas—to leak into your home's air supply. This is a serious safety hazard. During our seasonal maintenance or if we suspect an issue, our technicians perform a detailed visual inspection with specialized tools like borescopes. We also conduct combustion analysis to check for improper gas burning, which is a key indicator. If a crack is found, we will discuss replacement options to restore safe operation immediately.

Absolutely. Both low refrigerant from a leak and a failing heat exchanger can cause poor heating or cooling performance and system strain. Our diagnostic process starts with a comprehensive assessment. We check refrigerant pressure and superheat/subcooling levels to identify leaks and measure system efficiency. Simultaneously, we inspect the heat exchanger for stress cracks and test for carbon monoxide in the flue and air stream. This thorough approach allows us to accurately identify the root cause—whether it's one issue or a combination—and recommend the most effective repair for your specific system.
