"Hired Appliance Magician to service a GE Refrigerator that was not cooling properly. The technician", Artem Hxxxxxx, arrive on time and I immediately knew there was a problem as he did NOT speak English - Also, he did not know how to service my refrigerator - He spent 90% of the time on his cell phone getting instructions from his boss - He never checked the diagnostic service codes on my refrigerator and I could not t ask him to check them as we could not communicate. After 45 minutes of removing panels in my fridge and looking at things , he handed me his phone to talk with his boss (who talked in very broken English) who told me my defrost heater was broken and the fridge could be repaired for ;about $750 . My fridge had no frost/ice build-upo on any coils he checked, nor was there any water in the case, which my limited knowledge told me was not compatible with his diagnosis. I feel I was ripped off of the $69 trip charge as nothing was done, Company NOT vetted!!!"

We are family owned full service handyman service and Licensed General Contractor that does 90% of the work myself. On occasion I will have someone with me to aid in assistance. I always ensure the quality and take pride in my work. I am a licensed business owner, bonded and insured. I believe in “flat rate” pricing for the client versus an hourly rate, that way the client knows exactly the cost up front. An exception is for small assembly work, we have an hourly rate. I have lived and worked my business in the same general area for 40 years and I can assist you with any job. Like I always say, I do " a little bit of everything"!

"Most excellent. Very responsive in replying to our inquiry for work to be done, via text messages and e-mails. Larry and his assistant, Jesus, arrived on time and performed the work effectively and efficiently. They were friendly, professional and diligent in the performance of their work. We're quite happy with the doors fixed and would definitely hired them 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.
