FAQ’s About Heating & CoolingHere are some frequently asked questions about heating & cooling in the home:

1. What is the difference between “On” and “Auto” on the fan, and when should each be used?

When the fan is set to “On” it runs all the time, whereas in “Auto” mode, it will only run when the unit is triggered to heat or cool to keep the temperature at the setting it has been placed at. While being on all the time uses more energy, it can be useful to get constant filtering of the air in the home. The downside is the lifetime of the fan motor may be shortened by constant use.

2. How long does a typical heating & cooling system last?

A lot depends on how well the system is maintained and also how often it is used. The lifespan can run from a short 10 years to over 20 years with good care and regular maintenance. Sometimes it may be advantageous to replace a heating & cooling unit that may still be working fine but not have the efficiency of a new unit.

3. What does the SEER rating mean?

SEER stands for Seasonal Energy Efficiency Ratio, and thus is the rating that shows the efficiency of the unit. Currently a unit sold must be at least 13 SEER, and as technology increases, that minimum gets increased. The higher the SEER rating, the lower your utility bill will be, so it is advantageous to have the highest rating you can afford to purchase when replacing a heating & cooling unit.

4. What maintenance is recommended for a heating & cooling system?

There are things the homeowner can and should do, such as inspect and change the filter every month, keep air vents unobstructed, keep the units clear of household belongings, and keep the outdoor unit free of debris. Besides this, it is recommended to have a heating & cooling company come out once or twice a year to service the unit.

Contacting heating & cooling professionals is a great way to get all your questions answered about your specific unit and its potential lifespan. They can keep it running smoothly and efficiently, which can save you hundreds of dollars in utility and repair costs down the road.
