Heating and Air Conditioning questions, answered by experts

While spending money once or twice a year to tuneup your AC and furnace might seem like a waste of money, think again. The cost of HVAC maintenance is far less than the cost of replacing your furnace or AC unit, regardless of the type of HVAC system you have. Paying this smaller fee now will help you avoid paying much more significant costs in the future. Not to mention, having a serviced AC and heating system will help keep your home comfortable, no matter the season. 

Choosing a unit with higher BTUs can use more electricity if the BTUs are more than what’s necessary for your room size. However, choosing an AC with BTUs that match the size of your room or house, your unit will cool your space efficiently. On the flip side, choosing a system with not enough BTUs can cause the system to work harder to try to cool the space, leading to more electricity consumption and higher energy bills.

HVAC technicians charge around $175 per hour, but anywhere between $100 and $250 per hour isn’t uncommon. The total cost of your HVAC service depends on the type of work, the type of system, and more. Here are some important cost factors to consider to get accurate pricing:

  • Time of year

  • Urgency of your repair or service

  • Type of system 

  • Type of repair you need

  • Whether or not you have a service contract

  • Size of your HVAC system

  • Brand of HVAC equipment

The time it takes for an air conditioner to dry fully after cleaning depends on the unit's size and humidity levels. Most units will dry within two to four hours after cleaning, but check the manufacturer's recommendations for drying times. Make sure to leave the unit off until it's completely dry.

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.
