"They didn't seem interested in repairing my furnace. All they wanted to do was sell me a new furnace. The demeanor of the technician, Nicholas, changed to argumentative and belligerent when I said I was not buying a new furnace. When I tried to complain to the manager, he became argumentative as well. He did return the diagnostic fee after I told him I was getting a 2nd opinion."

"A prompt and thorough response, unlike simply informing me that there was nothing they could do, they actively researched the warranty on my current system (expired and void due to builder installation) before discussing a replacement option. I was then presented with several options, each accompanied by a quote. When asked, they recommended that I opt for a more economical quote that better suited my usage and requirements. I highly recommend this company. They were punctual and worked diligently, even during the peak summer months in the hottest room in my house (the attic). I will certainly recommend them to any of my friends and will utilize their services for any future needs related to air conditioning or furnace repair, as well as routine maintenance."

"This review is long overdue in my praise of Washington Energy Services for their customer service, pricing and workmanship ! My first interaction was in 1999 when they installed windows throughout my house. They are still in excellent condition. I might note I called them over 20 years later to inquire on how I could repair a broken slider and they sent someone right out, charging a very nominal amount to repair it. In 2020, I needed to replace my hot water tank, and the extremely knowledgeable Christy presented several options, answering my many questions. I settled on one with a booster that seemed to best fit my needs. Finally, in December 2023, I purchased a new gas furnace from WES. I had a minor issue with a fan switch and they responded quickly to rectify the situation. Within the past two months, I seemed to be having an issue with my thermostat (something they had not installed), and the manager, Greg, came out twice with his crew to explore the problem. Today they installed a new thermostat FREE OF CHARGE! Their excellent response and customer service is beyond any company I have hired. And I particularly love that they are family owned and have been around for decades. Their employees seem to be there for the long haul, which speaks highly of the owner. I refer all my friends and family and I won't go anywhere else for services that they offer. Many thanks to the staff I have interacted with over the past 25 years!"

"AirBest home services were amazing! I am so happy I put in a mini-split/heat pump and am amazed at how quiet it is and effective. Jason is awesome! He was very knowledgeable about rebate programs, made reasonable recommendations (rather than oversell), was quick with the quote, and got me scheduled within a week. He also offered interest free financing for a year! AirBest was $12K less than my second proposal (because they are a small business and more lean). The staff arrived on time, were respectful of my property, were able to problem solve effectively when things didn't go exactly as planned an got my two rooms installed beautifully and professionally in a day as promised! I liked them so much I promoted them to others in my condo complex. Thank you AirBest, can't say enough great things about you."

"I requested an HVAC service call quote from G&S Heating through Angi, and received a "deal" via Angi for $129. I chose them partly due to that price. G&S Heating ended up billing me $280, and said that was an old outdated deal and would not honor it. Irresponsible and incredibly poor customer relations. Also, the technician they sent did not seem very knowledgeable or experienced. He said the thermostat reading issue I was having would require another service call and the possible replacement of an expensive circuit board. I ended up fixing the problem myself. I will not be using G&S Heating again."

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.
