If you find that your heating or cooling system has just stopped working, it could be stressful and an emergency. Many homeowners will quickly search for emergency HVAC repair in Fort Worth after discovering that their heaters or air conditioners are not working. However, before making the urgent service call to get help, there are simple things you can do to see if the issue is something that can be resolved or to assist in the fast diagnosis of the issue by the technician. Taking a few minutes to check out your system can help you. It might even save you time, save you money, and keep you from panicking for no good reason.

Check the Thermostat Settings

Verify that the temperature setting is lower than or higher than the room temperature (seasonally appropriate). Sometimes batteries in digital thermostats die on their own, and the thermostat will no longer respond to your settings or requests until the batteries are replaced or until the thermostat has been restarted. Therefore, if you replaced or restarted the thermostat, the operation of that thermostat should have returned quickly. Connectivity issues or software glitches with smart thermostats can also interfere with smart thermostat communication with the HVAC unit. A quick reset of your smart thermostat or checking the Wi-Fi connection may solve your problem without requiring emergency service at your home.

Inspect the Circuit Breaker and Power Supply

If your system suddenly turns off, check the electrical panel for a tripped circuit breaker associated/related to your HVAC system. Circuit breakers can trip due to power surges, storms, or temporary overloads. Resetting the circuit breaker may allow the HVAC system to function again immediately. Next, check the outdoor HVAC condenser switch (on/off), examine the visible power cords for any signs of damage; also, check for accidental shut-off of the emergency shut-off switches that may be found near the indoor unit as a result of regular cleaning and other maintenance activities.

Replace or Clean Dirty Air Filters

When the air filters get too clogged with dust, pet hair, dirt, etc., airflow will be limited, forcing the HVAC system to work harder than usual. Over time, the strain on the system can lead to overheating, frozen evaporator coils, and reduced cooling or heating efficiency. To avoid a visit from an HVAC technician, remove the filters from the system and examine their condition. If they appear to be dirty or blocked, replace them with new ones. Some reusable filters can simply be washed with soap and water and allowed to air dry before reinstallation. Performing routine maintenance of your filters will improve your indoor air quality, reduce the occurrence of emergency breakdowns, and increase the longevity.

Examine the Outdoor Unit for Obstructions

Airflow may be restricted if the area surrounding your unit is blocked by leaves, dirt, grass, or debris, which will hurt the efficiency of your system. If the problem goes uncorrected, the system may overheat and eventually shut down entirely. After turning the power to the condenser unit off, take a couple of minutes to walk around the unit outside and inspect it closely. Remove any debris from around the condenser unit, and be sure to allow at least three feet of clear space around the unit. Look for any visible signs of ice forming, listen for any unusual sounds, or look for any damaged components on your condenser.

Look for Signs of Frozen Evaporator Coils

You may have weak airflow, warm air coming out of the vents, or ice building up around your indoor unit or the refrigerant lines. Restricted airflow, clogged filters, and low refrigerant levels are all common causes of frozen coils. Before calling for emergency HVAC service, turn off the cooling system and allow all the ice to melt away. Running the fan without cooling can help to speed up this process. Once all of the coils are cleared, replace any clogged filters and turn the system back on. If this issue continues to persist soon after the coils were cleared, a refrigerant leak or a more serious mechanical issue may be present, which would require the services of an expert.

Key Takeaway

If your heating or air conditioning isn’t working, and it’s hot or cold outside, and it’s uncomfortable, there is nothing worse than that. There are several troubleshooting methods to try that often lead to quicker repairs, lower costs, and sometimes you can fix the issue without a repair technician coming out. These are practical things that most homeowners can easily do themselves and will give a lot of useful information to the technician when they are trying to determine why the HVAC unit is not working. By being prepared with knowledge before calling for an emergency service, homeowners will be able to stay calm, make an informed decision on whether or not an emergency repair is needed, and maintain their heating and cooling systems so they last longer.
