The heat of the summer is back and in full force!
The hydro grid will be feeling the force today with all the air conditioners being turned back on to cool the homes after the fall-like weather we have had.
Even with this hot humid weather, your air conditioner can still freeze up!
If you only turn on your air conditioner when its very hot out or if your system is dirty. Both can cause the system to run continuous or cycle on and off too quickly and could over work the system which would eventually freeze up or a part could burn out within the furnace.
When the air moves over the A-Coil, which is located above the furnace, the A-Coil cools the air with the freon from the condenser. When the system does not get a chance to rest and is continuously running the A-Coil will eventually ice up causing the system to not work properly.
What Should I Do?
To avoid the air conditioner system freezing up there are a few suggestions.
1. Keep the temperature in your home set at a consistent temperature all the time. If the home requires cooling, the air conditioner will turn on.
2. If you only use your air conditioner when it gets very hot – begin by setting the thermostat just 2-3 degress less than what the current temperature is in the room. Once the house reaches that temperature, let it sit for 30 min and then lower it again by 2 degrees. By allowing your home to slowly be brought down to a comfortable temperature your equipment has a chance to rest and will avoid freezing up that constant operation can cause.
3. Set a realistic cooling temperature. On very hot humid days, your system will have a very hard time cooling your entire home or business after not being on for a day or more.
4. Ensure your filter is clean! A dirty filter will block air flow causing the system to over work.Filters are not expensive. Buy a few at a time and have them on hand ready to change!
5. Is your heating system clean? If your furnace and air conditioner are dirty this can cause your system to over work.
If you are doing all the correct things and its still not working properly, it could be low on freon or there could be a more serious issue. In which case you should call a professional!
Stay cool 🙂
An A-Coil and Furnace ready for installation in a customer’s home. The A-Coil is cased so it comes like this with the coil inside. The front of the case comes off to check or clean. A-Coils which do not come in a case have duct work built around them.
