FREQUENTLY ASKED QUESTIONS

How does TruTemp determine the size of Air Conditioner or Furnace needed for your home?

The size of Air Conditioner or Furnace you need is calculated by looking a number of factors which include looking at the square footage of your home, the window and door conditions, insulation, the amount of insulation in the walls and ceilings, amount of sunlight that comes through your windows, how much shade the home receives from large trees around the home or building.

Why should I go with a high efficiency furnace or air conditioner?

A high efficiency furnace or air conditioner will give you more economical utility bills. The additional cost of a high efficiency furnace is usually made up with in three to six years, air conditioners can take a little longer to recoup the higher initial investment.

Why is it critical to size an air conditioner?

When a system is oversized, you pay more than you need to at installation and you are not removing moisture as well on a hot, humid day. Your system should be designed to run at 100 percent at 90 degrees to maintain a indoor temperature of 73 degrees. The system should achieve about a 15 to 17 degree drop from inside to outside temperature. High humidity will reduce this difference.

Why do I have to line the chimney when a new furnace is installed?

The code of 1993 requires that all masonry chimneys be resized and lined with all new furnace installations. The flue gas from your old furnace was 400 to 600 degrees. The new efficient furnace is about 320 to 350 degrees. The flue gases start to condense at about 280 degrees and will produce acidic moisture that attacks the mortar and will damage the chimney over time from the inside.

What is AFUE?

You've probably heard the term, "Annual Fuel Utilization Efficiency, or AFUE" rating for gas furnaces, but what, exactly, does that mean? Quite simply, the AFUE rating is a measure of how much of each dollar's worth of gas burned by your furnace goes toward heating your home. Federal Department of Energy standards require that all new gas furnaces have an efficiency rating of at least 78%, which means that 78 cents out of every dollar's worth of burned gas translates to heat. The new ultra-high efficiency furnaces have AFUE ratings of over 90%. By contrast, no matter how well you think your gas furnace is working, if it was manufactured before 1982, chances are that at least 30 cents of every heating dollar is going right up your vent pipe!

What is SEER? (Seasonal Energy Efficiency Ratio)

The total cooling of an air conditioner in BTU's during a normal annual usage period divided by it's total electrical watt hours for the same period. The higher the number, the more efficient the equipment. Pre 1985 equipment is typically under 8 seer.
