"They destroyed the whole pipes that caused flooding to my neighbors. The water was off and every other day we need to go out to the street to turn it on. This company denied the responsibility but later reimbursed me for the first leak repair after employee acknowledging doing partial work. This project aims to address and fix the extensive leaks. Must be completely replaced, cause of leaks appears to be from over heating of the copper as locations are at ALL connections and bends in the pipe, too much to patch. You can contact me to this phone number: 9(16) 857-5652"

"Hire my Husband built an arbor to go over our living room sliding door (it was not a kit). Dawson worked closely with us on the design to insure it was exactly what we wanted. The team who built it were very detailed and consulted with us on each step of the installation. We couldn’t be happy with the results! We plan to have them help us with another project."

"Jeff has come to the rescue twice to my new build home. He came the first time in the middle of summer when the a/c would start up. It was just the fan running. He was able to repair the unit same day. Recently, the same thing happened but with our heater. The burners were not lighting up. Apparently the builders never put the cover on and they got clogged with dust and debris. He was able to get our heater working and cannot be more thankful. He was able to fix a couple of things in the attic that the builder just slapped on. I’m sure this system will not stand the test of time, especially here in Vacaville so I’ll trust New age when it’s time to replace this system"

Window a/c unit installations FAQs

Running a window air conditioner to cool a small room often costs less than $4 per day, making it cheaper than central air for single-room cooling. However, central air might be more efficient if you're using multiple window units or need to cool a space larger than 1,000 square feet. Choosing the right size AC is crucial—a unit that's too big or small can waste energy and increase costs.

Window AC units can use a significant amount of energy. These units use about 12 to 17 kilowatt-hours per day, significantly more than a refrigerator's one to 1.5 kilowatt-hours per day. To keep your energy costs down, run your window AC only when necessary, keep doors closed to contain the cool air, regularly clean filters and coils, and seal any gaps around the unit to prevent cold air from escaping.

Inexpensive air conditioner units are often not worth it. Low-cost products from popular brands like General Electric, LG, Whirlpool, or Frigidaire may be a reasonable investment. However, putting a small, budget-friendly unit in a large room wastes energy and shortens the life span of the AC since it has to draw more power and work much harder to cool the space. The unit will consume more energy and stress the motor and other internal parts, resulting in early breakdown and costly repairs.

The best deals on window AC units come during the fall when businesses slash prices to clear out old inventory. You can also speak with your local AC installer, who may get you a good deal on a window AC unit since they have access to trade pricing. You can also watch for discontinued products and flash sales in your area.

Window AC repair costs between $110 and $390, with most people paying around $250. Parts cost between $2 and $150, with the rest going toward labor, at around $30 per hour. The occasional one-off repair or a routine AC tuneup cost $75 to $200. Servicing can keep your AC running in good condition for several more years before you need to pay for a replacement unit.

Window AC units last eight to 10 years when installed and maintained correctly. High-quality models last up to 20 years with proper care and routine maintenance. The unit’s longevity depends on its construction quality, regular cleaning, and electrical safety inspections. Keeping the filters and coils clean and addressing minor repairs promptly extends its effective performance and ensures reliable cooling.
