"Post sales follow up by my salesperson is non existent. I needed some information regarding tax credits as promised as I was completing my tax return. I called the office requesting that my sales person give me a call back. I only had a couple questions. Then I left a message on his contact number. I did not receive any call. So much for being a "Diamond Club" member."

"The most trustworthy, reliable and competent outfit. They kept me appraised at all steps of the repair. Highly professional. They replaced the Freon, coil and filter. It was under warranty, I purchased the a/c from them 11 or 12 years ago and it was still under warranty so I only paid for the Freon. My home warranty under American Home Shield quoted me just under $2000 so this was a no brained. I am a confident D and H client and will continue to rely on their expertise, professionalism and compassionate service. Parts had to be ordered so I was without a/c during the 110 degree heatwave. No worries! D and H brought me at no charge a large portable A/C unit so we managed just fine. I highly recommend D and H!"

Build it, fix it, or remodel it, I can do it all! A one man show that has been doing this my whole life. From growing up on a farm to running a business of various services, I've been "in the business" of building, fixing, and/or maintaining anything and everything that has to do with a home. All jobs figured on my hourly rate, with a one hour minimum. No "set fees" regardless of time. (many companies do this KNOWING that they can get things done quickly, thereby making over $100/hr. on some jobs) I've built decks, garages, homes, and additions. I've remodeled kitchens, baths, basements, and virtually every room in a home. I've ran equipment, developed roads, driveways, and fixed drainage issues. I've replaced water heaters, faucets, dishwashers, washers and driers. Doors, windows, pet doors, and skylights are familiar to me. Various kinds of fencing, gates, and pet containment. If it has to do with home repair, maintenance, and/or improvement chances are I've done it. Give me a call and see what I can do for you.

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.
