If my system breaks down, should I repair it or replace it?
Deciding to replace a major component on an older system can be a gamble because there is no guarantee that something else won’t break next week. The risk is even greater when you’re facing a costly repair to system that is over eight years old, one that is in poor condition, or one that has not had regular maintenance service. Be sure to consider factors such as the age of the system, how long you plan to stay in the home, your current level of comfort, and the potential savings in energy costs. If you determine that your appliance is near or at the end of its useful life, you may decide to invest the repair cost towards a new system. For newer systems that have received regular maintenance, repair might be the better choice. Work with one of our technicians or comfort and installation consultants, and he will be happy to give you the technical information you need to help you make a well-informed decision.

How often do I change the filter?
Keeping your filters clean is one of the most important and inexpensive ways homeowners can both increase the performance and help prolong the life of their comfort systems. Dirty air filters can reduce the amount of airflow through your system, making your system work harder. Homeowners should avoid running their comfort systems without filters. Filters improve indoor air quality, while preventing the accumulation of dust and dirt on the working parts of your furnace or air handler. Accumulated dirt can drastically reduce your system’s efficiency and performance, and it is frequently the cause of system breakdowns.

You should change your filters whenever they are dirty. For an easy rule of thumb, the Department of Energy recommends replacing regular air filters in your furnace every month.

If your system has an electronic air cleaner or media filters, consult the manufacturers’ recommendations on replacement. Some air cleaners have washable filters, and others require changing only once or twice a year. If you are unsure about what type of filtering system your comfort system has, just ask your service technician or call or click here.
