"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

A 3-ton AC unit is probably too big for a home that’s 1,200 square feet. If you have a 1,200-square-foot home, you likely need a unit that’s somewhere around 1.9 and 2 tons. An AC unit that’s too large will be really inefficient and cost you a lot of extra money on your bills. 

Some HVAC systems tend to use R410A refrigerant, although if you have an older model it may be using R22. R22 is banned due to its harmful environmental and health impacts, and it is a sign that your AC unit is old enough to consider a replacement and the significant efficiency gains that could come with it.

Ceiling fans can be a great way to cool your home without the expensive utility bill of running an air conditioner. Plus, ceiling fans can sometimes run in both directions, pushing hot air down in winter and pulling cold air up in summer. With that said, air conditioning might be the only thing that helps if you live in a very warm climate.

Unfreezing an AC unit is not a DIY project unless the problem is a dirty air filter. Changing out an air filter is easy for homeowners, but otherwise, trying to repair ductwork, refill refrigerant, or replace a blower fan motor are tasks best left to the pros. Otherwise, you could cause further damage to your cooling system or even harm to yourself.

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers, or ASHRAE, sets the standard guidelines for air changes per hour in homes and businesses. The International Residential Code, or IRC, also sets ACH requirements for residences and bases those requirements off of ASHRAE standards plus climate specifics related to your location.
