The best value is from Sun Kool AC
they have the Kool Club Plus
which packages maintenance, extended warranty and a surge protector
it gives you the complete package
the techs are clean, professional and courteous
some other companies charge less for maintenance but they dont do a full heating and cooling tune up
make sure you check on exactly what you get and exactly what is covered
there are a lot of flim flam AC companies out there
my two cents
