Spring and Fall Rejuvination Tune-Ups

Below is a basic checklist of things that are checked during our spring and fall tune-ups.  These bi-annual tune-ups are included with both of our Service Club Memberships along with discounts on reairs.  Which HVAC components are checked at which service and which items apply depends entirely on the type of heating and air conditioning equipment you have.  This tune up checklist covers all makes and all models of residential heating and air conditioning systems for both spring and fall maintenance.   For example, since a Heat Pump is basically an AC running backwards, Heat Pump systems use all the same refrigeration components year round so we check them in the spring and in the fall.  Where as a furnace / AC combination only uses the refrigeration components in the summer time and has a whole seperate bunch of furnace parts for the heating season.  Indoor and Outdoor on the list refer to regular split systems component locations.  Package units just combine the normally located inside HVAC components in a the same box as the outdoor unit.  It still has primarilly all the same HVAC components they are just almost all located outside instead of having some inside and some outside. We have found that having an actual comprehensive maintenance checklist helps bring a little clarity to what is actually being checked and at the same time it helps us maintain consistency and quality control.  Just like your medical doctor keeps a copy of your medical records, we keep a copy of your HVAC tune up records.  With years of records we can give you better and more accurate advice as your system ages.
