Heating and Air Conditioning questions, answered by experts

It depends on the specifics of your warranty. The motor is likely not covered if you’re working with a limited warranty. The same goes for other components like the compressor and evaporator coil. Some extended warranties will cover the blower and fan motor, so read the fine print before signing up. Additionally, the manufacturer may offer a warranty for the parts, including the motor, though there’s likely to be a strict time limit for this coverage.

No. HVAC, which stands for heating, ventilation, and air conditioning, includes all of the systems that work together to regulate a building’s temperature and humidity levels. In comparison, air conditioners only provide cooling. You can have an air conditioner as part of your HVAC system, but not all HVAC systems include air conditioners.

Your air conditioner can temporarily run with a dirty filter, but it won’t work as efficiently. It will need to work harder to blow cool air throughout the room or house, and this can eventually cause the air conditioner to overheat or die prematurely. It’s much more cost-effective to clean or replace filters than to pay higher utility bills each month and replace the entire AC unit more often.

You should get anywhere from three to five quotes for HVAC replacement to get an idea of the average cost of a new unit. Although this quote-collecting process can be time consuming, it allows you to compare what work is required, what type of unit you should install, and how much you should expect to pay for the service.

When first installed, flex ducts shouldn’t cause airflow problems in your home. However, because flex ducts aren’t the sturdiest and require extra support, they lose their durability over time and begin to sag, which can inhibit airflow down the road. Also, if your flex ducts aren’t tight enough, your HVAC could work twice as hard for the same air pressure. If you’re worried about the airflow in your home, a rigid duct may be your best bet.
