Wanted system cleaned and looked at real good, worried it would not make it thru another year. Had a company out a few months back for one of those 29.95 specials. All he did was try and sell me a new unit, spent less then 5 minutes working on my AC. Called Total Air last week, set up appointment. They spent 45 minutes cleaning, checking things. Told me the unit was OK, but getting to the end of it's use full life. I asked him what it would cost to replace, gave me a few options, never tried to pressure. Plan to hold out for awhile, but I will be calling them to replace my unit when I'm ready.
