"We were in the market to convert off oil and switch to a heat pump system. CRM Green Energy Consulting helped us every step of the way. They arrived on time and were very professional during the home assessment process. We agreed to the proposal and set up a time for installation the following week. Throughout the whole process CRM was communicating with us on progress. There was a placement issue for one of our mini-splits and one of CRM’s Carpentry team members came out and opened a wall and patched/painted like they were never there. Super friendly team members and very knowledgeable on green energy and home heating efficiency. At the end of the project they sat us down and taught us how to use the phone app for our GE mini split unit. They helped us fill out of MassSave rebate form as well! We couldn’t be happier with CRM Green Energy! We are so glad we chose them for our heat pump project!"

FAQs for window a/c unit installation projects in Wilmington, MA

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.
