The following are Frequently Asked Questions regarding your heating and cooling needs:
The short answer is the size that is appropriate for the space. This is done by having a professional run a Manual J load calculation to determine the precise amount of BTU's required to cool and heat the space. If sized too large the home will cool rapidly, but fail to remove sufficient humidity creating a cool, clammy sensation. If undersized, the unit will run non-stop never reaching the thermostat set point during warm weather.
A maintenance plan is not an expense; it's an investment that pays dividends each month with lower operating costs. A well maintained system lasts longer and defers the cost of replacement. In addition, those expensive emergency repairs which happen during the most inopportune time all but disappear with regular maintenance.
This question is often times dictated by individual comfort. However, there are a few general rules. Use a set-back thermostat to reduce or raise the thermostat set-point during sleep, or away from home. During the winter, you can expect to save 3% of your energy costs for every degree you lower the thermostat. In the summer, you can save 4% of your energy costs for every degree you raise the thermostat. In the DC market, most homeowners set their thermostat at 74 degrees in the summer and 72 degrees in the winter.
