Does Your HVAC System Need a Repair?
Signs your heating or AC system may need repair or replacement.
Dirt and buildup can prevent proper airflow within HVAC systems. A clogged filter, condensate drain, or water valve may be the culprit. Power supply issues will also prevent the supply of warm and cool air.
But often, problems are associated with older systems that are less efficient at converting energy into heat. Outdated parts in older systems are more expensive to replace. Consider replacing HVAC systems older than 10 years.

1. Temperature Change
Unexpected temperature changes may indicate dirt and buildup, power supply issues or frozen pipes.

2. Malfunctions
Malfunctions in your home’s systems, like humidifiers and thermostats, might be caused by circuit breaker issues or dirt and buildup.

3. Unusual Smells
Smells coming from your furnace could be caused by a gas leak. This should be treated immediately.

4. Strange Noises
Noise is often associated with parts of the system that are responsible for airflow.
