Did you know the Department of Energy estimates that more than half the energy you use each month goes to heat and cool your home?
Here we review some basic installation procedures that are common to most systems. We also offer some insight on choosing the right contractor and the right system for such an important home improvement project.
Basic Installation Procedures
The installation process will be different for each job, depending on your HVAC contractor, the type of unit you purchase and your home's unique needs and features. However, there are some basic procedures you can count on when having your system installed. Becoming familiar with the process will help you understand the work going on in your home, so you can ask questions along the way. Here are some general installation steps that you should expect from your contractor:
1. Dismantle and haul away existing air conditioner materials, and clear all related debris before starting the new install.
2. Acquire proper permits and schedule required inspections from the city where you live.
3. Install new ductwork (if indicated in proposal), or prepare existing ductwork for use with the new system.
4. Properly position and place outdoor air conditioning unit.
5. Make proper and safe connections and determine the correct sizing for the electrical and refrigeration lines and piping.
6. Install a new thermostat or reuse the existing thermostat.
7. Charge and start the new system according to manufacturer specifications.
8. Conduct a post-installation check or inspection before final inspection.
Understanding these general procedures will help you to stay involved as you add comfort to your home with a new central air conditioning system.
Choosing the Right Contractor
You will be placing a great deal of trust in the contractor who installs your air conditioning system. Proper air conditioning installation requires some complex calculations, proper training and years of experience. You want a contractor who stands behind their work and is going to be around years from now to service the system.
Before signing an agreement with any company, verify the following:
· They are licensed with the state and city for heating and air conditioning work.
· They carry both general liability and Workers' Compensation insurance.
· They can provide names of satisfied customers from your area.
· Their technicians are factory-trained and certified by the product manufacturers.
· They are members in good standing with the Better Business Bureau and have no unresolved complaints.
They should be able to show you copies of all certificates and licenses.
You should be satisfied that you understand the work to be done and that you approve the costs to be charged.
