HVAC problems are inevitable but never ignore them. Fixing issues immediately prevents expensive repairs and avoidable breakdowns. It prolongs the unit’s life, boosts efficiency and comfort.

Just imagine your household without air conditioning on the hottest summer day. This is avoidable if you take the time to understand how the system works and fix problems quickly. Here are seven HVAC problems to never ignore.

Strange Noises

Unfamiliar noises such as banging, grinding, squealing, or hissing from the unit are impending problems. The sounds indicate a loose part that needs tightening or replacement. If you ignore the problem, it will only worsen and eventually lead to a complete unit breakdown.

Schedule an HVAC repair immediately. The expert will inspect the unit, identify the problem, and fix it accordingly. They may also lubricate parts to reduce friction and prevent further damage.

Water Leaks

Another serious problem to never ignore is water leaks. If you notice water pooling around the unit, it’s a sign there’s a refrigerant leak. The evaporator coil may be frozen, preventing the unit from draining properly. This is a serious problem that needs immediate address.

Ignoring the issue will worsen and lead to more expensive repairs. Another cause of water leaks is a clogged drain line. You can quickly fix this by flushing the line with bleach or vinegar.

Poor Airflow

If you notice that the airflow from your unit is weak, try resetting your system or it can be a sign that the ductwork is clogged or there’s a problem with the blower. Poor airflow makes the unit work harder, leading to higher energy bills and a shorter lifespan.

A faulty thermostat, clogged air filter, or closed vents can also cause poor airflow. Inspect the unit and ductwork for any blockages. Clean or replace the air filter and open any closed vents. If the problem persists, call an HVAC technician to inspect the unit.

Higher Energy Bills

If you’ve noticed a sudden spike in your energy bills, it’s likely due to an HVAC problem. A unit that’s not working properly has to work harder to maintain the desired temperature, leading to higher energy consumption.

Inspect the unit for any issues and call an HVAC technician if you can’t find the problem. They will inspect the unit and fix any issues causing it to use more energy than usual. When the unit is too old, a replacement may be necessary.

Inconsistent Temperature

If you notice that the temperature in your home is inconsistent, it’s a sign that the unit is not working properly. A faulty thermostat often causes inconsistent temperature, but it can also be due to a clogged air filter or closed vents. Inspect the unit and make sure the thermostat is set properly. Clean or replace the air filter and open any closed vents. Remember to change the thermostat batteries every year.

Yellow Pilot Light

If you have an older gas furnace, take note of the color of the pilot light. A blue pilot light indicates that the unit is working properly. On the other hand, a yellow pilot light indicates a problem with the unit. It could be due to a gas leak or a dirty burner.

When the light goes off, it means the thermocouple has failed. This is a serious problem that needs immediate address by an HVAC technician. Ignoring it could lead to a fire. The good news is that newer HVACs have an electronic ignition, which doesn’t use a pilot light.

Poor Indoor Air Quality

When the air in your home is stuffy and smells bad, it’s a sign of poor indoor air quality. This problem is often caused by a dirty air filter or insufficient ventilation. Other poor indoor air quality signs are excessive dust, pollen, and pet dander. To improve the air quality, regularly replace the air filter and make sure the vents are open. You can also buy an air purifier to remove contaminants from the air and enjoy the atmosphere with aesthetic lights.

Never Ignore HVAC Issues

Ignoring HVAC issues will only make the problems worse. Because not all problems are easy to detect, schedule regular maintenance and inspections. The effort will prevent small issues from turning into big, time-consuming, and costly problems.

Call an HVAC technician right away if you notice any of the above problems. They will inspect the unit and make the necessary repairs.
