What Causes HVAC To Stop Working?

Have you ever gotten home to a hot house or experienced a sudden breakdown of the air conditioning? Most people panic when they reach out for assistance, thinking about how much it will cost to fix the problem.

Furthermore, you will probably receive a higher charge for emergency service if it is after hours or during the weekend. Whenever your air conditioner fails to keep your home cool, troubleshoot it before looking for an HVAC repair service near me. You may be able to do the fix yourself.

However, if you’ve experienced problems with your air conditioner for a long time, from uneven cooling to an air conditioner that isn’t working, call our qualified professional to assist.

Typical HVAC Problems

The cause of a malfunctioning air conditioner could be a variety of factors. There are, however, some common problems. It is important to recognize their nature to deal with them successfully.

Listed Below Are The Most Common Problems That Can Arise With Your System


Airflow can be decreased, air quality can be compromised, and power consumption can increase when filters are dirty. Additionally, they can cause the coil to freeze, making the air conditioner work harder.

By replacing your air filters regularly, you can avoid AC problems. Filters should be changed once a month for flat filters and three times yearly for pleated filters. You can find us by searching HVAC repair service near me to assist you with replacing your filters.

Your HVAC system may not get the correct central control system instructions if the old dial-type thermostat is incorrectly calibrated.

There is a quick fix for this problem. Depending on your thermostat, you may need to recalibrate or replace it. You can also get a smart thermostat installed by our air conditioning installation expert in Diamond Springs.

Your air conditioner transfers heat using refrigerant. You might notice a lot of hot air coming out of your AC system when it doesn’t have enough refrigerant.

Unlike modern air conditioners, older air conditioners use Freon or R-22. This refrigerant is no longer allowed due to its harmful effects on the ozone layer. Due to limited availability, refrigerant leaks can be more expensive to repair.

Puron and R-410A are more environmentally friendly and are used in modern air conditioners. Invest in a new unit if your current one is outdated.

  • Duct Leaks

HVAC air is transferred throughout the room via ductwork connected to the walls and ceilings. It is, however, possible for cooled air to enter inside your walls, where it won’t contribute to your room’s ambient temperature if there are cracks or holes in the ducts created by rats or any other reason.

Consequently, your HVAC system uses more energy, and your energy bill increases. This is a clear indication you need professional help.

To Sum Up

Participating in a preventive maintenance program is the best way to avoid air conditioning problems. It is possible to fix problems such as low refrigerant, dirty coils, and bad wiring during a routine maintenance visit.
