Q: What is the difference between high efficiency and standard efficiency furnaces? A: "Standard-efficiency furnaces convert roughly 80% of the energy from gas into heat. High-efficiency furnaces convert 90-97% (depending on the model) of the energy from gas into heat. So basically: high-efficiency furnaces use less fuel."
Q: So . . . they are environmentally-friendly? A: "Yes, but that’s only one benefit.  High-efficiency means lower utility bills, not just nickels and dimes either; the savings can be hundreds of dollars a year, especially if you use propane to heat your home. Many high-efficiency models also have advanced motors that use less electricity and are extremely quiet."
Q: High-efficiency furnaces cost a lot more though, right? A: Well, yes and no. The initial price of the furnace is more, but there are a number of federal tax credits, instant rebates, and local incentives that can lower the price substantially — anywhere from $600 dollars all the way up to $2,900 dollars."
Q: How do I know if my air conditioning system is running efficiently? A: Request an appointment to determine how efficiently your current system is running. A 13 SEER air conditioner is the minimum efficiency level now made in the U.S. If you’re running a unit with a lower level SEER, it may be time for you to consider unit replacement. A 13 SEER unit can amount to energy savings of about 18% compared to a 10 SEER unit. A new, high-efficiency system can help you save 60% on cooling costs.
Q: My air conditioner is tripping the breaker, what do I do? A: This is a serious issue; a tripping breaker is usually a sign of a grounded compressor. Resetting the breaker could cause internal breaker arching and a possible fire. You should turn the air conditioning off at the thermostat and us for help.
Q: My air conditioning system is original to the home, which was built in 2004. Should I replace it? A: If your air conditioning system is older than 7 years, it’s likely inefficient by today’s energy efficiency standards. In 1992, the government established a minimum cooling efficiency standard of 10 SEER for units installed in new homes. Since January 23, 2006, all air conditioning equipment has a minimum efficiency standard set and mandated by the U.S. Department of Energy. We’ve often found that 10 SEER units (standard in homes built through 2005) operate at 6 to 8 SEER or less. To improve efficiency, a homeowner can replace the unit or opt for an air conditioning tune-up, if the unit is in sound shape.
