"A-maze-ing. These guys were GREAT - I won't be calling anyone else in the future. First, they spoke to the woman in the house exactly as they did to the man - no dumbing it down for the ladies. Physically showed me what was going on and explained it well so I understood what was needed and why. They let me know which repairs needed to be done immediately and which could wait - no hard upsell at any point. They set reasonable expectations for what improvement I could expect with each step. Polite, friendly and helpful, showed up well within the estimated window. Before each visit I got a text with the name and picture of the tech who was on their way and a phone call from them to confirm. In 5 visits I worked with only 2 point people, meaning they weren't having to start from zero every time someone walked in. They charge by the job, not the hour, meaning the work was done quickly, but with quality. I had someone I know take a look at the work and they said everything looked very well-done. After each step they followed up with me by phone to find out if I wanted/needed anything else. In short, I had a shockingly great experience with them and can't recommend them highly enough."

Heating and Air Conditioning questions, answered by experts

While your AC unit may still run even if its capacitor is going bad, doing so takes a lot more energy, so it can drive up your electric bill and cause further damage to your AC unit’s parts. If you suspect a bad capacitor, it’s important to have a professional diagnose and fix the problem before you continue to run your AC.

You should use a breathable, weather-resistant cover with ventilation. It can be a top cover or a full cover that has mesh to allow airflow. A full, non-breathable cover can cause moisture to build up, leading to rust, frozen parts, and corrosion. A full cover also attracts unwanted critters, such as mice, that can damage the wiring and your unit. If you need to protect your AC unit from falling icicles, choose a sturdy top cover or piece of wood that prevents icicles from damaging your unit.

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.

This depends on the extent of the freezing. Some ACs only need an hour or two to thaw out, but others may need a full day to completely unfreeze. Once you turn off the system to let it unfreeze, check it periodically to make sure the drain pan doesn’t overflow. When you turn the system back on, keep an eye on it to ensure it doesn’t start freezing again.

A calculation method that your HVAC contractor will use to ensure your system does what it's supposed to is measuring duct output, or its CFM. The calculation requires knowing the cross-sectional area of the ductwork and determining the air speed past any given point within it.
