Changes have taken place in today's heating and air conditioning market. Everchanging technology makes 10-year old equipment out of date. Whether it be natural gas, L.P. gas, oil or electric heat, what was state of the art 10 years ago may not measure up to today's standards.

But, by starting with the basics, any system will best perform if that system is sized correctly with the right amount of BTU for the job. A system too large will run in short cycles, cause drafts, use more fuel, and reduce comfort. Too small may not heat or cool in normal conditions.

Some of the most asked questions:

1. How does a 90% efficiency furnace give you 90% efficiency?
2. How does a heat pump work?
3. How does a Geothermal heat pump system save money?
4. Should I use a closed loop or open loop Geothermal system?
5. Why does my new furnace sound like it does?
6. With my high efficiency gas furnace, the temperature at my vents is not as warm. Why?
7. Heat pumps - do they really work in Ohio?
8. Why should I install a programmable thermostat?
9. Why should I install an electric air cleaner?
10. Why should I install a humidifier?
11. What is a U.V. air purification system?
12. Are 2-stage burners and variable speed blowers worth the money?
13. Why is Allied Services better than the rest?

After all, being in business for over 53 years, we must be doing something right.
