When is a good time to have my system checked?
We recommend checking your air conditioning and heating system before each season, ie, in the spring and in the fall.

What can I do to increase my systems efficiency?
We recomend keeping filters clean. Keep leaves and debris from around the outside unit. Wash coils every two to three months. Install a programmable set-back thermostat. If you have a heat pump, the settng should be set at one setting and remain at that setting.

Can changing my existing system save me money?
An older furnace is only 60% to 70% efficient. The newer units are 80% to 94% efficient.

Most older air conditioning units are 5 to 6 S.E.E.R. (Seasonal Energy Efficiency Ratio). New models will run 13, 14, 15, 17, 21 S.E.E.R. The higher the rating, the less electricity your unit will use. Each household usage is different. Some homeowners see savings of 30-40% per year.

When are the best times to purchase a new system?
Presidential doesn't raise its prices during peak times. But in the Spring and Fall, the manufacturers often have specials on humidifiers, air cleaners, and thermostats, as well as financing packages. Call us for more details about these specials or check our "Specials" page for current items.

What can I do to improve indoor air quality?

What is the new 13 S.E.E.R. changes as of January 2006?
Manufacturers can only produce 13 S.E.E.R. (Seasonal Energy Efficiency Ratio) units.
