Your HVAC or heating, ventilation and air conditioning system is one of the busiest working systems in your home, and also one of the most important. This also means that it can act up quite often, or just break down altogether and stop functioning. Here are a few troubleshooting tips that you should consider:
Test your furnace by setting it to “heat” mode and program the thermostat to about three to five degrees above your home’s current temperature. Wait for a few seconds, then look for the nearest open register to see if there’s any hot air coming out. If there isn’t any, or if the level is too low, you might have a heating problem that will need professional help.
Do the same test for your AC – if it’s not producing any cold air, there might be a water buildup below the unit, which can cause the cooling coils (when they are dirty and dusty) to freeze up. In this case, turn off the unit and let it sit for three hours, then clean up the clogged cooling coils.
The main problem that ventilation systems often face is when too much dust and dirt are already circulating within. Find out by checking the filter. Dirty vent fan filters should be replaced as soon as possible. You should also work on cleaning the dust itself.
