Does A/C need maintenance?
I replaced my 20 year old HVAC two years ago; and got a 10 year extended
warranty. Since then I have had the furnace cleaned each winter.
Today I got a post card from the installer recommending that I get
maintenance on the A/C. I have always thought that A/C didn't need
anything as long as it was working okay. Is preventive maintenance
necessary?
