What a High-Pressure HVAC Switch Does and Why It’s Important

The compressor is one of the most important components in your HVAC system. It’s also one of the most costly. One large part of making sure that you have functional heating and cooling equipment in your Grove City, Ohio home is keeping your system’s compressor working like it should. Fortunately, this job is made easier by the addition of a high-pressure HVAC switch. Read on to find out how.

High-Pressure HVAC Switches Detect Significant Increases in Pressure

High-pressure HVAC switches are automatic safety features that protect HVAC equipment from serious and potentially permanent damage caused by high pressure. When these switches detect excessively high air pressure within HVAC systems, they instantly shut everything off.

High pressure places extraordinary stress on heating and cooling components, shortens their lifespans, and causes home energy bills to soar. By turning HVAC systems off, these switches force homeowners to take immediate action to resolve the problems that are causing in-system air pressure to mount.

You Can’t Turn Your HVAC System Back on Until Pressure Problems Are Resolved

The costs of replacing a damaged compressor are daunting, to say the least. In fact, for some households, replacing older cooling systems may be the most cost-effective choice. High-pressure HVAC switches help consumers avoid expensive and preventable compressor repairs by shutting everything down before any serious harm is sustained. Moreover, these switches keep HVAC systems from turning back on until the underlying problems have been fully resolved.

What to Do When Your HVAC System Gets Turned Off By a High-Pressure Switch

If you have an HVAC system with a high-pressure switch that’s been turned off, you can try resolving the problem by checking your equipment’s air filters. Dirty, blocked filters are among the most common causes of excess pressure within these systems. You should also check the air vents throughout your home to make sure that none of these avenues for air distribution are blocked or closed.

If dirty air filters or blocked air vents aren’t the culprits, contact one of our licensed HVAC technicians. You may have torn or otherwise damaged ductwork, blockages within your HVAC ducting, a bad check valve, or low airflow at the condenser. We will inspect the entire HVAC system to diagnose and resolve the underlying issue. Once proper functioning and balanced air pressure have been restored, your HVAC system can be turned back on.
