The HVAC system is one of the most important inventions of modern times. Your HVAC system works round the year to maintain a comfortable indoor temperature. In addition to heating and cooling your home, your system plays a vital role in maintaining the indoor air quality.
Like all other equipment, your HVAC system requires periodic maintenance. Regular maintenance minimizes problems and maximizes efficiency. A well-maintained system is more reliable than a poorly maintained one. That said, even a well-maintained system can develop problems and stop working.
When your HVAC system stops working, do not lose your cool. Call in a Walnut Creek HVAC contractor to get to the root cause of the problem and eliminate it.
We have compiled a list of expert tips for troubleshooting your HVAC system.
Try Resetting Your System
Sometimes, resetting your system can resolve the issue. Every furnace, heat pump, and air conditioner has a different reset method. If you do not know how to reset your system, check your owner’s manual for instructions. If you do not have your owner’s manual, find it online using your system’s model number.
Check the Ducts and Air Vents
Make sure nothing is obstructing the ducts and air vents. The vents should be wide open. If a piece of furniture is blocking a vent, remove or rearrange it for optimal airflow. Make sure your ducts are clean, as unclean ducts can affect the HVAC system performance.
Check Your Thermostat for Issues
Thermostat issues can lead to problems with your HVAC system. A faulty thermostat can cause your system to turn on at the wrong time or prevent it from turning on at all.
Make sure your thermostat is getting power. Dirt can affect your thermostat’s calibration, interfering with its operation. If grime has built up inside your thermostat, clean the contacts with a piece of paper. Suppose you have an older model, clean by dusting inside the cover.
Have a battery-operated thermostat? Check to see if the batteries are charged. Without charged batteries, your HVAC system won’t receive the message to turn it on. Make sure your thermostat is programmed correctly.
Improper positioning can also affect a thermostat’s performance. Do not place your thermostat in an area that receives direct sunlight. It should be no more than five feet from the door. For best results, you want your thermostat to be centrally located and away from heat sources.
Check Furnace and AC Wires
In addition to causing HVAC system performance issues and failure, faulty wiring, loose connection, and exposed wires could cause an electrical fire. Wires in a system are prone to fraying and corroding, especially if exposed to the elements.
If your system doesn’t start, check your wiring, but be careful! Do not handle any potentially damaged or exposed wires as they present a danger of electric shock or electrocution. Stay safe and reach out to an HVAC contractor for help immediately.
Check HVAC Filters
HVAC filters are designed to trap contaminants such as pollen, dander, dirt, and dust particles. Over time, these contaminants can clog HVAC filters.
Dirty and clogged filters affect HVAC performance and cause poor airflow. When cold air gets trapped inside your system, ice forms on its coils, rendering it inoperable. To prevent issues, replace your HVAC filters every 30-90 days. For best results, use HEPA filters.
Furnace Troubleshooting Tips
Is your furnace not heating properly? Here are some things to try.
➢ Check to see if the power breaker is off.
➢If you have a gas-fired furnace, make sure your furnace is getting gas and that nothing is blocking the gas valve. Check other natural gas appliances to see if they are working correctly.
➢ If your heat pump does not generate enough heat to achieve your desired temperature, adjust your thermostat.
➢If there is not air coming out of your furnace, check the belt and replace it if it is broken.
➢ Is your oil burner not functioning correctly? Try replacing your filter. Make sure it is receiving electricity. Check to see if a sensor has signaled it to shut off.
Troubleshooting AC Performance Issues
➢ If your AC is not cooling, check the filters. Over time, filters accumulate dust and dirt. Periodically clean or replace clogged and damaged filters to help keep your unit operating efficiently.
➢ If your AC is not cooling properly, check the outdoor unit. Clean off debris on the outside unit and repair any damaged fins. Clean area around the unit and the evaporator coil. Make sure the system sits level.
➢Is your AC unit consuming more power than usual? Check your system for refrigerant leaks. Call an expert to handle refrigerant leaks.
➢ If your AC is making a banging, thumping, or banging noise, there could be a problem with your blower or motor assembly. A faulty compressor will produce a screeching noise. Damaged electrical components produce a buzzing noise. If your AC is making these weird noises, have your contractor check different components.
➢ If you have a drainage problem, the drain pipeline could have become clogged with dust, dirt, and algae. Gasses and foul odors can get into your home. Do not ignore the problem. Have your contractor inspect and maintain your drain line.
