Below are some of the most frequently asked questions and concerns we receive from customers.
If you have a question that is not here, send us a message with the form below.
You could try:
Rebooting your furnace: Try to turn the furnace power switch off for 1 minute. The power switch can often be found, just above or beside the furnace. Sometimes the main control board becomes locked out and will not properly send the right electric signals to the main components.
Checking your filter! Furnaces built since 2000 are most prone to shutting off when a furnace filter becomes too dirty. This impedes air-flow. Simply remove the filter, clean it or replace with a new one, and then re-boot your unit.
If that doesn’t change anything, check and make sure that all breakers are in the ON position. If a circuit breaker has popped or a fuse is blown, you may need to reset the breaker or replace the fuse box. Check that all switches in and around the air conditioner are set to the ON position including the external safety switch which is usually located on an outside wall next to the condensing unit.
If your unit has one, check the condensate tray to see if there is an excessive amount of water in it. Sometimes this tray is installed in remote air handlers using condensate collection instead of a condensate drain. There may be a sensor switch that shuts off your unit when too much water is collected.
Just like your furnace filter, your air filter needs to be cleaned and checked regularly. If your heating and cooling units are separate, so are your filters. If you heat and cool from the same unit, then they are the same. Make sure you visually inspect your duct work to make sure there are no crimps or disconnects. You should also check that your register dampers on your vents are open.
temperature outside are huge possibilities.
Things such as dirty air filters, undersized ducts, damaged blower motors and dirt build up can seriously impede air flow. This can cause the
evaporator coil to drop below freezing. Humidity in the air and dirt can collect on the coil causing ice to build up and hinder the systems cooling ability. Refrigerant leaks or low levels of refrigerant can also cause pressure drops in the air conditioners evaporator coil, which will allow moisture in the air to freeze and accumulate on the coil.
Almost all outdoor units do not function well in temperatures below 60*F. When the temperature at night drops, the system may not be able to operate properly causing it to freeze up.
Should your unit ever become frozen, the first thing you should do is shut it off and let it defrost. Once it has defrosted, you will need to check airflow, clean or replace dirty filters or remove any visible dirt or obstructions.
***To keep your air conditioner running in good condition, here at Comfort Zone Heating and Air Conditioning we recommend that you spray around the base of your outdoor unit with bug repellent. This will prevent bugs/ insects from crawling in, and getting zapped by the contactors which will in turn shut your unit down.***
