The 5 Most Common HVAC Problems

Most modern HVAC systems are built to last for two decades, or even longer if maintained properly. They are durable and precise pieces of equipment that are made to deliver reliable heating and cooling 24 hours a day. However, with such a demand, it should come as no surprise that an HVAC system can suffer from occasional issues over time.

Here are the five most common types of HVAC problems and what you can do to help prevent them from happening.

Improper Use and Maintenance

An HVAC system is manufactured to work optimally based on certain conditions. These include keeping the windows and exterior doors closed, keeping all of the vents in the home open, replacing the air filter every one to three months, and keeping the area around the outside compressor unit clean and free of obstructions. These tasks fall upon the homeowner. If any one of these four conditions are not met, the HVAC system will operate inefficiently with the results being felt not only in your home’s comfort level but in your utility bill as well.

Refrigerant Leak

If an HVAC system is low on refrigerant it means either the technician did not charge the system adequately upon installation or there is a leak somewhere in the system. If the problem is a leak, then simply adding refrigerant will not solve the problem. In order for the system to run at its peak level, the leak needs to be repaired and the refrigerant charge needs to match the manufacturer’s specification, no more and no less.

Leaky HVAC System

If you notice the floor is wet around your HVAC system, especially on humid days, then there is a chance that the condensation drain may be clogged with debris. This will cause the condensate pan to overflow.

Electrical Issues

HVAC systems have a lot of electrical parts and terminal connections that can wear out over time, causing a number of other potential problems. The compressor and fan controls are especially prone to failure on systems that cycle on and off frequently. This is why every aspect of the electrical system is checked during a standard HVAC service call.   

Sensor Issues

An HVAC system features sensors throughout it that measure air temperature and other important data. These sensors help ensure that the equipment is working properly. But, over time these sensors can get knocked out of position and when this happens, it causes the sensors to record inaccurate readings and the system to suffer from erratic heating or cooling performance.

What our customers say...

I purchased the special spring tune up offer from All In One for both of our HVAC systems. They promptly called to schedule the visit, showed up on time, and did an excellent job performing the work. The technician fixed a loud rattling noise that was coming from one of the fan units (turned out to be the fan hitting a wire housing when it would turn on and off), added Freon to one unit and no additional expense was required. He placed shoe covers on when entering the house to keep things clean, and communicated well what he had done and his assessment of things at the end of the visit. Thankfully, everything look good. They also provide a 30 day warranty on your entire HVAC unit after performing the tune-up. I will definitely be using All In One for our HVAC needs going forward.
