How can I increase my home’s heating and air conditioning efficiency?
To increase the energy efficiency of your home, it is best to select an air conditioning and heating system that is designed to be efficient. It’s important to keep in mind that larger models don’t always mean better heating. Often times, larger systems can lead to reduced efficiency. You should select a system that is appropriate for your living, depending on the shape and size of your home. Staying on top of filter maintenance, regular cleaning and changing them will also increase your energy efficiency. Another great way to be energy efficient is to install equipment that helps moderate temperatures like shades, drapes, and shutters.
How often should I have my filters replaced?
Filters are incredibly important for maintaining clean air quality and increasing energy efficiency. If you have filters that are washable, we suggest that you have them cleaned every month. If you use pleated filters we suggest replacing every three months.
Which HVAC system is the best for my home?
In order to decide which HVAC system is best for your home, it’s important to consider the dimensions of your house and needs of those under your roof.
