Hmh Air Conditioning & Heating | Emergency HVAC Services in Warminster, PA

A common culprit for furnace ignition failure in our area is a dirty or faulty flame sensor. Over time, dust and soot can coat the sensor, preventing it from detecting the flame and causing the system to shut down for safety. Our technicians can quickly clean or replace the sensor to restore your heat. Other frequent causes include a faulty igniter or issues with the gas valve, which we can also diagnose and repair.

Clogged condensate drains are a frequent issue for Warminster HVAC systems, especially in humid weather. The drain line removes moisture from your air conditioner or high-efficiency furnace, and over time, algae, mold, and debris can build up inside, causing a blockage and potential water damage. We recommend having your condensate drain line cleaned as part of your annual AC or furnace maintenance. Our service includes flushing the line with a safe solution to prevent clogs and keep your system operating smoothly.

You should call for emergency service if you have no heat during freezing temperatures, a complete loss of cooling during a heatwave, or if you notice signs of a water leak from your HVAC unit, which could indicate a serious condensate drain backup. For your safety, also call immediately if you smell gas or hear unusual, loud noises from your system. As your local HVAC experts, we prioritize these emergency calls to protect your home and comfort.
