When it comes to your homes HVAC system you want to make sure you are taking care of it properly so that you will get many years of dependable use from it. There are several myths about HVAC systems that we hear regularly. Today we are going to share some of the most common ones.
You should keep your AC unit covered in the winter.
This is a myth that we hear a lot. It seems logical that during cold weather you would want to protect your outside unit, but these systems were actually designed to be outside. It can withstand the cooler temperatures, the rain, and even the snow. Covering your unit could cause damage that other wise would not occur. It could cause moisture to become trapped and in turn cause mold to grow. Small animals and rodents are always looking for warm homes in the winter and covering your system may make them more likely to make a home there. This could lead to a whole other mess of problems.
Turning your system on and off will help with energy costs
Another myth we get a lot is that if you are gonna be out of the house you are better to turn off your system. Unfortunately, that is not the case. Turning your system on and off consumes more energy than leaving it on. You can invest in a programmable thermostat and set it for different temperatures when you know you will be out.
Leaving vents closed in rooms that aren’t in use will save money
This can actually cost you more money because it can interfere with the systems air flow. While it would seem like your using less energy by not heating or cooling those rooms it can actually cause blockages in the vents since newer furnaces run on the square footage of your home.
It is always better to purchase a bigger system
Most of the time bigger is better, however when dealing with heating and cooling systems, this isn’t always true. If your system is too big for the area it will cycle on and off more quickly and this will cost more money and also overwork your system, requiring more maintenance and eventually a new system quicker than usual. It is always best to consult an HVAC specialist to help you determine the size unit that is needed for the square footage and personal needs of your home.
You only need to change your filter twice a year
Being HVAC specialist, we so often here people say that they were under the impression that a filter only needs to be changed when you have your semi-annual services. However, this is not accurate. It is ideal to change your monthly to make sure your system is performing at its best.
In conclusion, we hope that we have helped bust some of the common HVAC myths that you may not have known were myths.
