"Overcharged by WAY too much. The hydrostat charge was $862.90, and they installed a different brand than was on the invoice. The cost on Amazon for that unit is $188. Taco Zone Valve charged $745.56: valve on Amazon: $134.00 Same with other charges $3609.80 total. Less than 3 hours labor x 2 guys... who showed up late in the day when they scheduled for the morning."

"During the heat dome days we found out our air conditioning needed recharging. They insisted on up front payment (first red flag) then quoted over $800 to refill the units (2). They did not look for nor try to fix the leak but instead gave me a proposal over $3,000 to come back and fix the unit(1). I used them because they were the ones who could come the quickest. Never again."

Heating and Air Conditioning questions, answered by experts

If left untreated, a frozen AC unit can lead to costly damage, especially to the compressor and evaporator coils. When ice forms on the evaporator coils, they become brittle and more susceptible to breaking. Plus, a freeze makes your AC system much less efficient, which means it's wasting energy and costing you more in your monthly energy bills.

The size window AC you need depends on the BTU and the size of the room you’re cooling. For a room with 8-foot ceilings, look for about 20 BTU per square foot of the room. For example, a 12-by-12-foot room should have an air conditioner with 2,880 BTU. You can buy something slightly more powerful, but don’t overshoot the BTU for a small room, or you’ll waste energy and have higher bills.

Don’t run your AC with a wet filter. It can cause your AC to work too hard, which will run up your utility bill and cause extra wear and tear on the system. You could also spread moisture and mold throughout your house. Turn off the AC, remove the wet filter, and check for cracks or clogs. Fix the problem (with a pro’s help, if you need it), and put a dry filter in place before you turn the system back on.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

Turn your system off when you're toasty or when you're out to prevent unnecessary wear. Using the timer on your thermostat so that it switches off when it reaches a certain temperature or turns on just before you get back from work is best. An annual maintenance contract can be helpful to ensure your system receives these important services at regular intervals.
