Heating and Air Conditioning questions, answered by experts

Not necessarily. Some portable air conditioners may be vented out a door, wall, or ceiling—or even into another room. It’s not necessarily dangerous to run a portable air conditioner without venting it, but it is counterproductive since the unit needs to vent the heat in order to cool the room down in the first place. Without venting your portable AC unit, you’re essentially running a dehumidifier and increasing the temperature in the room. 

If your home has an existing forced-air heat system, you can add a central air conditioner to it. An HVAC technician can retrofit your forced-air heating system by installing an evaporator coil onto the furnace plenum, the box next to the furnace that draws in air. Once installed, the air conditioning coils use the furnace’s blower to circulate the air.

While it’s possible to only replace an evaporator coil to keep your AC running, this could cause issues down the line. An AC system relies on the harmony between its condenser and evaporator coils for efficient operation. Replacing only one coil, especially in older units, can cause compatibility issues, leading to inefficiency and potential system breakdown. 

As AC units near the end of their expected lifespan, investing in the cost for a new AC system is typically better than paying for individual component upgrades to avoid costly repairs and ensure optimal performance.

Diagnose whether your HVAC damper is bad by assessing airflow. For a manual damper, close it and run your system. Air should stop flowing through the associated vents. If you feel air, it’s likely a bad damper that requires repair or replacement. Automatic dampers should maintain your desired room temperature. If not, they may be faulty, and you may need to invest in some HVAC repair costs.

You reset your AC after a power outage by turning off the air conditioner from the thermostat, resetting the circuit breaker, waiting 30 minutes, turning on the AC from the thermostat, and waiting 10 minutes to see the impact. Sometimes, with a power outage, the AC needs time to reset itself, so resetting the circuit breaker alone may not do the trick.
