General System Questions
What is system matching for optimum efficiency?
How long should my furnace and air conditioner last?
What size furnace do I need?
Should I consider changing my furnace before it needs expensive service or breaks down completely?
What is the warranty on my furnace or air conditioner?
Why should I maintain my furnace?
Why is it so important to keep my furnace filters changed?
In the heating season, a dirty filter can cause the system to starve airflow, cause it to overheat and shut down.
In the cooling season a dirty filter can cause the evaporator coil (which allows refrigerant to cycle through to produce cool air) to freeze up and shut the system down.
1″ filters should be changed monthly, 4″ filters should be changed every 3-6 months.
Why doesn’t my humidifier work?
The filter (also known as a pad or water panel) should be replaced a couple times during the heating season as hard water deposits form more quickly on the filter. If the filter is showing signs of wear or water deposits, it should be replaced.
If your humidifier has a winter/summer damper control on it, turn it to winter for the heating season and summer for the cooling season (the humidifier should be off in the summer).
Also check all drain lines that come from the humidifier to make sure they are free of any obstructions.
Efficiency Ratings Explained
What is AFUE?
Cost Savings: If you have an older furnace (with an AFUE of approximately 55-60%), you could save up to 40% on your heating bills by replacing it with a new high efficiency furnace! The cost to replace your old, inefficient furnace is paid back through lower utility bills.
What is SEER?
What is HSPF?
Cost Savings: Higher efficiency in heat pumps and air conditioners usually means higher equipment cost but lower utility bills. Ask our comfort advisor to help you determine about how long it would take you to recover the additional cost in energy savings. Of course, long after the payback, you continue to save on your energy bills.
