Faulty HVAC Installations Reduce System Efficiency
If you are planning to buy a more efficient furnace or air conditioner when the present one finally dies or keeps requiring expensive repairs, keep in mind that efficiency ratings don’t mean much if your new HVAC system is not installed properly. For instance, you may be presented the option to upgrade from a 13 SEER air conditioner to a 16 SEER unit at a higher price, but without making sure the rest of your system is operating properly you may be wasting your money.
For instance, if your ductwork is undersized, it will not deliver adequate airflow for the new AC unit. If that is the case, you may get cooling in your home, but the reduced airflow will also reduce efficiency. Another common problem is air leaks. If your ductwork is leaking, or not properly insulated, your efficiency savings may be lost outside the home. The best practice standard for an HVAC estimator is to look at all these different areas of your HVAC system to make sure they are working properly.
A good HVAC estimator is part detective, and he may ask you questions about comfort in different parts of the house, your power bills, etc. And he should certainly look closely at the ductwork condition. There is a lot more to selecting the right air conditioner than just size and SEER. If you want a thorough, detailed HVAC proposal, include Air Control Heating and Electric, Inc. in the list of companies you call for an estimate.
