I have been in the construction industry for over 25 years. As a homeowner needing to get things done that I do not have time to do, I tried to hire people to do the work for me. If I contacted companies, they did not answer the phone and if you left a message they did not call back. If they did call back or they would schedule appointments and never show up or if they did show up you would never hear from them again. If I was lucky to find one that provided an estimate, they did not know how to do the projects requested. Larger companies do not want to do the "little" things. At the point of getting so frustrated, I decided to start this business so that other homeowners would not have to go through this. I have hired professional and qualified people; drug test and background checks have been performed on them to ensure clients safety. The technician comes out, accesses the work and pricing is given on site. If pricing is accepted, the technician will perform the work immediately. You do not pay for the work until the job has been completed to your satisfaction.

"Their tech came to our townhome for the HVAC heat pump issue, spent more than 3 hours diagnosing the issue and then told us that we had to replace the zoning control board and the thermostat at $1400 in total. We were charged $390.00 for the diagnosis. We were not convinced by what he told us. Then, we called another HVAC contractor from different company to look at the issue. He was able to pin point the issue with the unit in 15 minutes and fixed it by refilling refrigerant at around $300! What a difference! I will never trust and use Premier HVAC Mechanical Corporation again!"

FAQs for window a/c unit installation projects in Alpharetta, GA

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.
