"This company has treated me well, especially Mike Museus, who worked over a year (last summer and this spring) to find out why there was a fluid leak in my new AC unit. The leak didn't affect the cooling of my home so I wasn't concerned, but Mike was persistent, even to returning finally with an "expert" to help diagnose the problem. What they found was that the A-coil above the furnace was full of tiny pinholes. On the day this was to be replaced, Steve came before 9 a.m. to remove the defective A-Coil and install the new one. He worked on it all day, without lunch or a break, leaving shortly after 5 p.m. There was no charge, as it was still under warranty. With all that, he still took the time to explain to me why the replacement was so important: that the defective A-Coil could eventually leak enough to damage the furnace below it. Because he was using solder, I believe, to install the new part, he turned on the ceiling fan in the adjacent room to mitigate the fumes. My only complaint is that a few of my vinyl floor tiles were damaged/discolored by the soldering process. That part of the flooring has had water damage before and is missing a few tiles so, after a day of hard work, he may have attributed the damage to work done before. It's not a big deal; I just wish he'd have said something. I have to hand it to Steve, though; he was working by himself, which frequently required him to leave the furnace area to check the outdoor AC unit, then rush back to the indoor work. I think it might have been a two-person job. At least, an assistant could have facilitated some of the work done."

Heating and Air Conditioning FAQs, answered by experts

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.

If there’s a freon leak in your home’s AC unit, it will cause the system to work overtime to cool the house. That issue will result in higher energy bills and it will take much longer for cool air to disperse throughout the home. If your system has a freon leak during the summer, it can make hot days miserable. That’s why it’s important to hire an HVAC professional to resolve a freon leak as quickly as possible.

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, government incentives and programs are available to encourage energy-efficient upgrades in many regions. These incentives may include tax credits, rebates, grants, and low-interest loans for homeowners who invest in energy-efficient improvements such as HVAC system upgrades, insulation, and efficient windows. The availability and specific details of these incentives can vary by location, so check with your local government or utility company to explore your options.

No, it isn’t necessarily bad to turn your AC on and off frequently—contrary to popular belief. Even if you stop and start your AC throughout the day, it won’t use as much energy as it would if you ran it nonstop. 

If you’re concerned about your power consumption and energy costs, there are a few simple ways to use your AC more efficiently. Regularly cleaning the filters, scheduling routine maintenance, and using a programmable thermostat are all great choices.
