FAQ

Most systems have a lifetime of 10 to 20 years. As your equipment gets older, its efficiency can decrease dramatically. You may notice that it gets noisier and needs repairs more often. When a unit begins to show it’s age, you have two choices. You can overhaul the system or replace it. Because heating and cooling technologies improve over time, a new system designed with newer, more energy-efficient equipment makes sense, especially if your system is 10 or more years old. We can estimate the cost of a new system as well as a payback schedule that will show you how newer technology will pay you back in lower energy usage.

Without warranty coverage, a breakdown can mean significant expense in parts, labor, or both. However, with one of our service agreements, you avoid that unexpected significant expense. While no warranty can guard against every possible problem, we can explain the broad range of protection our service agreements afford.

The average home spends about $1,900 annually on energy bills. Heating and cooling accounts for as much as half of a home’s energy use. The EPA provides important recommendations for energy-efficient equipment, including proper sizing, quality installation and maintenance, and other home improvement considerations to help you get the most out of the heating and cooling products you purchase, save energy, and save as much as 20% annually on your total energy costs.

ENERGY STAR qualified products prevent greenhouse gas emissions by meeting strict energy efficiency guidelines set by the U.S. Environmental Protection Agency and the U.S. Department of Energy.

The water heater Energy Factor is a measure of the overall efficiency of the water heater. This is determined by comparing the energy in the heated water used daily to the total daily energy consumption of the water heater. The EF can be used to compare the energy efficiency of water heaters. Water heaters with higher EFs will have lower annual operating costs than comparable models with lower EFs. A higher EF signifies a more efficient model. Water heaters with high EF ratings may cost more initially, but save energy and money in the long run. Eventually, they will pay for themselves through a lifetime of energy savings.

What Our Clients Are Saying

I can’t say enough good things about this company, they truly do live up to their name: RELIABLE!

S. Mahoney

I have health issues that make it fatal to be in hot temperatures for very long. My AC unit broke down (the motor and the starting component, I believe) in the middle of the night, and with high temperatures expected the next day, I was really…really scared. I called this company and they were extremely understanding.…

C. Abner

The guys were great – very professional, very nice and polite, and very careful not to disturb or damage any of my wife’s Christmas decorations in the house. All in all, the process went very well, reducing…
