I can't remember how we came upon this company, but dealing with this company last year was very pleasant.  After calling several A/C companies, we settled on having this company put in the new A/C unit with a good warranty on it.  We had a Carrier unit put on and it was in the middle of the range in terms of price - not the cheapest nor the least expensive.  \n\nI think after everything was said and done, it was close to $7K for a new ground unit to adequately cool an almost 1800 sq ft home in central AZ.  \n\nThey did not try to high pressure sell us or anything.  Once we decided and set up the appointment, they came at the time they said they would and installed the outside unit as well as replaced the heater coil or whatever it's called up in the attic.\n\nWe were up and running in no time and the electric bills have been lower with a new more efficient unit.  It keeps the house cool and works great.  We typically don't run the unit in the winter - the heater, so at least part of the year it gets rest.\n\nWould use this company again.  Very professional.
