"A rather amazing fellow named John Lower is JW Geothermal. I take John to be "one of those guys". Give John a paper clip and he'll build you a shopping center. I was desperate when I went looking for someone to repair or replace our non-functioning central A/C with the historic Pacific Northwest heat dome on the way in late June of 2021. I just got lucky when I got a call from John who said he could be at our place the next day. Most of the other "big" companies were telling me I would have to wait until July. My dear girlfriend is not "heat hardy" to put in mildly and it was a scary deal. I was operating on the bogus assumption that we needed a new unit as the one we have is fairly ancient, an older than dirt Rheem. John arrived on schedule and swung into action. In a matter of maybe 20 minutes (max) he diagnosed the issue (a bum capacitor) and installed a new one that he had in his major pickup truck. John's a big guy with big hands but he works with the skill of a brain surgeon. He saved our bacon for sure. I simply can't recommend this fellow highly enough. Oh, and did I mention that he is a nice guy in the bargain."

Heating and Air Conditioning FAQs, answered by experts

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.

Capacitors are the most frequent part of an HVAC system to experience failure. These components are crucial for starting the motors that power the fans and compressor, but over time, they may become worn or fail due to electrical surges or regular wear and tear. When capacitors malfunction, HVAC systems may experience decreased heating or cooling efficiency, or even total system failure. Replacement or maintenance of capacitors is a common requirement for the optimal functioning of HVAC systems.

While both have advantages, a split system is generally cheaper than a ducted one. Because they are less invasive to install, the labor costs are lower, and they can be more energy efficient. But, a ducted system might be worth the investment if you run it more frequently. 

You should plan to change your AC unit's filter every one to three months, depending on the manufacturer's recommendations. You should also clean the coils at least once per year, but if you have pets or someone in your household has allergies, you might need to clean them more often. Fortunately, many pros will clean the coils and change the filter for you during an inspection, which you should schedule once or twice per year.

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.
