Q. How often should I change my air filters? 
A. Once in a month. A good rule of thumb to use and a helpful way to be reminded is to change the filter or filters when you get your electric bill. If you have indoor pets, you might need to change your filter or filters twice a month depending on the quantity of pet hair and dander. 
Q. Which filters are best? 
A. The cheaper, thinner filters or 30-day throwaway filters are best. Yes, pleated filters do filter out more particles but restrict the air-flow thus minimizing the heating and cooling. 
Q. When should I call for routine service? 
A. Once in every two years. This will entail washing coils along with coil cleaner, checking capacitors, freon levels and drains. 
Q. What should I do when I think something is wrong with my HVAC system? 
A. In summer, turn the system off and switch on the fan, then call us with a detailed description of the problem. 
In winter, turn the system off completely and then call us with a detailed description of the problem.
