A & B Air Conditioning & Heating | Experienced HVAC Repair in Airmont, NY

Common signs include inconsistent heating where some rooms are hot while others are cold, frequent pressure relief valve discharges (you might hear dripping or hissing), and your boiler pressure gauge reading consistently too high or too low. Fluctuating pressure can strain your system and reduce efficiency. Our technicians can diagnose the root cause, whether it's a faulty expansion tank, a leak, or a failing pressure relief valve, and perform the necessary repair to restore safe, stable operation.

In our humid Airmont climate, algae, mold, and mineral deposits naturally build up in the dark, damp environment of your AC's condensate drain line. Regular clogs can cause water to back up and potentially damage your system or your home. We recommend a professional preventative maintenance visit, where we thoroughly clean the drain line and may suggest installing a safety float switch to shut the system off if a clog occurs. For homeowners, pouring a cup of distilled vinegar down the drain access quarterly can help reduce buildup between professional services.

For a boiler, first check the pressure gauge. If it's critically low, you can often safely repressurize the system using the boiler's filling loop (consult your manual). If the pressure drops again quickly or is dangerously high, turn the system off and call us. For a clogged AC drain, you can try clearing the accessible PVC pipe with a wet/dry vacuum. If the clog persists or water is leaking, shut off the AC to prevent water damage. In both cases, our local team offers prompt emergency service to diagnose the issue, prevent further damage, and get your Airmont home comfortable again.
