"I would like to share with you how I was treated by your company. In the month of December 2016. I purchased a heating system from your company. I do live in Oxnard and I know that is quite a way for your company but I do appreciate that you did that for me. All went down as planned and the guys that came out were very nice and helpful. But then a couple of years later the heater went out so I called your office to see if the heater was under warranty and to have someone come out and fix the problem. I spoke to Susan several times. The end result was that I lived too far and that your company was very busy and that I should find another heating company in my area. She was very rude to me and had very poor customer service. I did call another heating company and the problem was fixed after another $400.00. It was a transformer that went down. Susan said to me "you liked the price, right". I said yes. She said then I would suggest you look on yelp to find another company in your area. So unprofessional. I was in shock and didn't know how to respond."

"Air Tech was great. I would HIGHLY recommend. I initially had 2 other companies besides Air Tech come out for a replacement estimate. Price wise Air Tech was right in the middle but were doing a lot more than the other 2 quotes I got. For example they were changing the copper refrigeration lines, which the other 2 weren’t going to do. When I called the other 2 companies to add the lines in there was going to be an additional $1500-$2000 charge. I’m very pleased with this the work that was done by Air Tech"

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.
