"Where do I begin! 5280 Heating, Cooling & Refrigeration has been extremely professional since day one. I have been dealing with Cody Jr since the beginning of the AC condenser install. He was VERY professional and communitive during the whole process. The other companies' mis diagnosed my issue and quoted me WAY more than 5280 did. Cody, Rick AND Jacob all assessed on how to remove my old AC condenser, removal of my a-coil and disposed of it. They proceeded to install my new condenser and Cody explained to me on what they were doing on each step and overall, it was a GREAT experience that I had with ANY outside vendor. I 100% recommend their services to any home owner! Cody was a real delight to deal with and put not only myself, but my wife at ease with the work completion that they did. Thank you, Cody and your company 5280 Heating, Cooling & Refrigeration on replacing and installing my AC unit."

"I cannot begin to thank Josh enough for the work he did on my home regarding my upstairs bathroom. Everytime we took a shower in the bathroom the water would leak and we were super concerned because the water was starting to drip from out light fixtures and started creating pockets and puckering.on our hallway walls it was seapimg between the wall and the paint. We were super concerned as we.tried having another handyman and a plumber to help.us diagnose the problem. Both recommended a complete overhaul of the bathroom and charged an outrageous price that we couldn't possibly afford at the time. Luckily for us Josh reached back to us when we initially started looking for a handyman. Josh told us he had a lot of experience regarding these matters and based on pictures of his previous work we felt very confident he could help us. We were already under the impression we would have to redo our tub and he offered a reasonable price if that was the case, however Josh really secured our confidence when he told us it may not even be necessary. He was really methodical and did his best to not to demolish the wall to get access to the pipes of the tub and shower. Fortunarely he localized the issue to a leak from our pipes and saved us thousands of dollars that we thought we would have to spend. It seemed like hard work, but he had it fixed by the next day and we haven't had a problem since. I highly recommend Josh regarding any work on your bathroom. If I wasnt selling my house I would have him re-do the whole bathroom based on his previous work and the quality job he did for our bathroom. I can't thank him enough!"

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.
