I moved into a new home and the HVAC does not work right, What should I do?

Most  warranties only have 1 year, so don’t put off complaints. Get the model number and the name of the manufacture located on the unit.  Call the manufacture to see if your product falls under the manufacture warranty.  If  not, then ask if the product is still in production.  If it is, wonderful.  You can call a service technition to fix the problem.  If it is under warranty, ask what the procedures are for returning merchandise to the manufacture.

How do I know the installation price is ok?

  Get three similar bids. If the bid is not the same in every detail, then the comparison is impossible for the homeowner. If the different bids specify different sized equipment, then you either need an engineer to size the equipment, or get a bond against incorrect work.

How do I check for a dirty evaporator coil?

Probably the easiest way is to measure the temperature of the air entering the system is at the filter.  Then, measure the temperature at the closest register. A good system will show a 20-25 F degree difference in temperature. A restricted airflow will have a higher differential. This is a subjective decision. If the house does not cool properly after a technician adds Freon to the system, and the house has balanced airflow to the rooms, then I would clean the evaporator coil. Many th...
