Water? Cold Air? The Top Reasons To Call A Pro For A Heating System Repair

Posted on: 26 August 2022

What are the top reasons to schedule a heating system repair? A DIY approach to furnace or boiler repair can result in excessive damage, extra costs, or it can even create a hazard. Heating, ventilation, and air conditioning (HVAC) contractors have the knowledge and experience necessary to service complex equipment.

Take a look at some of the most common causes of HVAC problems and the reasons to call a professional.

A Water Leak

There's a puddle under your heater—and it didn't come from the rain or snow outside. Why would a residential heater leak water? Home heating appliances leak water for a few different reasons. The heat exchange process that a high-efficiency unit makes creates condensation. This water has to go somewhere. That's why these types of heaters have condensate lines, drains, and pumps.

A leaky condensate line, clogged drain, or broken pump will allow water to leak out of the unit. This problem often results in a puddle on the floor or water dripping near the heater. Older furnaces that don't have condensate lines and drains may still leak condensation-related water. These units have pipes that vent or exhaust gasses. An improperly sized exhaust pipe prevents the gasses from venting. This can cause excess condensation that leaks from the pipe. Along with water, the pipe could also leak gasses. This can create a dangerous situation that requires immediate professional attention. Never ignore a leaking exhaust pipe. If you see water or bubbles coming from the pipe, turn the heater off, leave your home, and contact an HVAC pro ASAP.

No Heat

The heater is on—but your home is cold. There isn't one cause for this common issue. To find out why your home isn't heating properly, you need the help of an HVAC technician. It's possible that you've set the thermostat to the wrong temperature, placed the thermostat incorrectly, or that this device is no longer working correctly. 

Air filters are another common culprit behind this problem. Dirty or clogged air filters are an easy-to-fix issue that can limit a furnace's heating ability. Dirt, dust, and debris can block the airflow, making it difficult or impossible for heated air to move into the system's ducts. If you've never changed the filter, the technician can show you how to perform this maintenance task. 

More serious issues could include mechanical failure, a problem with the pilot light, duct damage, or overheating. A qualified technician can inspect the unit, assess wear or damage, diagnose the cause of the problem, and repair the heater.
