Q. How often should I change my furnace filter?
A. It depends of the type of filter that you have and the conditions in your home, but typically, we recommend that you check the filter at least twice a year and change it if appears clogged. As a general rule, the higher efficiency filter you have, the less it needs to be changed. The following is a link to an interesting article in the Washington Post that discusses furnace filters.

A. You wouldn't buy a brand-new car and expect to never have to put air in the tires, change the oil and check out any unusual noises, would you?

Q. Why is One Area of the House Always Hotter or Colder Than the Rest?
A. There is always one room that is freezing in the winter or blisteringly hot in the summer, no matter what you try to do. These hot or cold spots are usually caused by poor airflow. To improve the balance of your system, try increasing the fan speed on the furnace’s blower. This will ensure that the optimum amount of air is delivered to each register in your house, giving you more even heating and cooling for greater comfort. You should also make sure that doors and windows are properly sealed against drafts and that insulation is adequate to prevent warm or cool air loss.

Q. When is the best time to replace a furnace or air conditioner?
