I am replacing a 31 year old original furnace and adding central a/c. I currently have an evaporative cooler as my main cooling source. I live in a split entry home in northern Utah and the evap cooler works fine for my cooling needs. I'm just tired of trying to find people to climb up on my roof to service it and it's over 12 years old and I'm not sure how much longer it will last.
I have found a premiere Lennox contractor in my area that's been in business for 54 years. NATE certified. Performed Manual J & D calcs. I've checked with my state to verify their contractor's license as well. Since this contractor is a premiere dealer, they're offering the Lennox 12 year parts & labor warrnty on the furnace and a/c.
Furnace: 70,000 btu - Total Manual "J" Heat Loss = 46,727
A/C: 2 TON A/C (2-1/2 TON COIL) - Total Manual "J" Heat Gain = 18,470 btu's
I was considering a Lennox XP15 heat pump but decided against it for the following reasons:
Greater cost up front
Keeping snow away from it in the winter (location would be below a deck where snow piles up after shoveling off deck)
The air coming out of indoor vents from a heat pump is cooler than the warm air from a gas furnace
Concerns that the heat pump will be running year round thus making it more likely to break down sooner than using a furnace & central a/c.
I used this website to help determine my utility costs.
Your cost for a gas furnace would be $ 521 per year.
Your cost for an electric heat pump would be: $ 480 per year.
These costs are based on the following assumptions:
1. The heated area of your house is: 1550 square feet.
2. Your house's insulation is: More than typical. R57
3. The winter heating load hours for your location is 2443 hours.
4. The efficiency (AFUE) of the gas furnace is 95%.
5. The gas furnace does not have a standing pilot light.
6. You pay 77 cents per Therm for natural gas.
7. Your monthly customer charge for natural gas is $5.00.
8. The efficiency (HSPF) of the electric heat pump is 8.7.
9. You pay 7.8 cents per kilowatt hour for electric power.
10. Your monthly customer charge for electric service is $3.
When calculating my cost per therm, I only used the cost for Nov 2009 - March 2010 as those are the primary heating months in my area. Cost per killowatt hour was the same for the past 12 monhts.
I am aware of the federal tax credit, state rebates, local utility rebates and manufacturer's rebates for my furnace & a/c.
Does anyone have an opinion on any of these Lennox products? Any advice you'd like to share?
