How often should I replace my furnace filter?
There’s no one-size-fits-all answer. The frequency of filter changes is driven by how much your heating and air conditioning system operates, which is also driven by your individual climate. Hold the used filter up to the light and compare it to a clean, spare filter. When light is obscured by captured dust and dirt particles, the old filter should be changed.
It is always a good idea to change filters at the start of the heating and cooling seasons and then in between according to your need. Also, it is a good idea to have your heating and air system checked at the beginning of heating and cooling season to insure proper operation.
What is a SEER or EER?
SEER is the abbreviation for Seasonal Energy Efficiency Ratio. The U.S. government uses SEER as a standard energy efficiency rating, reflecting the overall system efficiency of your cooling system. Since 2006, all residential air conditioners sold in the United States must have a SEER score of 13 or higher.
EER is short for Energy Efficiency Ratio and doesn’t take into consideration the time of year, but rather the system’s energy efficiency at the peak operating use. Both ratings should be considered in choosing cooling products.
The Federal government developed the ENERGY STAR program for high efficiency central air conditioning systems. In order to qualify, the system must have a SEER of at least 14.
We’re replacing our AC, how do we pick a system and an installer?
Since your HVAC system has a life expectancy of about 12 years, replacing your system is a big financial decision!
When choosing a contractor, pick a company to install the unit based on quality and customer service. The name brand of the equipment is often not as important as the installing contractor.
A Mrs. Michal HVAC technician makes sure your duct system is sealed tight with the proper amount of return air, and that you’re replacing your unit with one properly sized to your home.
What is radon?
Radon is an invisible, radioactive atomic gas that results from the radioactive decay of radium, which may be found in rock formations beneath buildings or in certain building materials themselves.
Radon is probably the most pervasive serious hazard for indoor air quality in the United States and likely responsible for thousands of deaths from lung cancer each year.
Testing for radon allows you to take action to protect your family from this harmful gas.
My system is old, but still works. Should I replace it?
Although your furnace or air conditioner may be working, if it is more than 12 years old you should consider replacing it with a new high efficiency system.
A new heating and air conditioning system could save up to 50 percent on energy costs, and save you money in the long run on repairs. More efficient systems will also keep your home cooler in the summer and warmer in the winter.
