Air Conditioning FAQs, answered by experts

In most cases, you should hire a professional to carry out services on your HVAC system, as the components are complicated, expensive, and potentially dangerous to work with. However, there are a few things you can do on your own to keep your HVAC system in good condition, including changing your filters every three months, keeping the area around your outdoor condenser clear of debris and plant growth, making sure your or intakes aren’t blocked, and keeping an eye out for increased energy bills, strange noises, and unusual odors related to your equipment.

Yesh, heat pumps can easily cool homes when the weather reaches over 100 degrees Fahrenheit, just as powerful air conditioners can. The key is sizing the heat pump correctly for the size of your home and your climate. A local heat  pump professional can help you determine the right size and type for your home.

If you’re looking for an energy-efficient heating and cooling system to heat a compact to average-sized home, then a ductless system is absolutely worth considering. The installation is less hassle when compared to a ducted heat pump system, and because your electricity bills should drop, it’s an excellent long-term investment.

Here’s how AC professionals will clean your AC coils:

  1. Unplug the AC unit or turn off the breaker to the unit in your circuit breaker box.

  2. Remove the faceplate.

  3. Spray a vacuum hose attachment or compressed air can to remove debris, dust, dirt, and grime.

  4. Use a soft-bristled fin comb to remove stubborn caked-on debris.

  5. Use the vacuum hose to suck up any extra debris.

  6. Take a coil-safe cleaning solution and spray it onto the coils. Try to choose a no-rinse solution.

  7. Let the solution sit for at least 15 minutes.

  8. Gently wipe away loosened grime and debris with a microfiber cloth.

  9. Reattach the faceplate, plug in your AC system, or turn the breaker back on.

Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.
