Hello!!! I’m Alex Ruffing, welcome to my page! I’m a born & raised Northern Virginian with 19 years in construction services (and counting). I started young, with family, on area commercial jobs; Wolftrap, Metro Garages and Park & Rides, and many of our shopping plazas. Then spent some time traveling the east coast building in the industrial sector; concrete, sky rises. Now I am happy to be home and operating as a Handyman(+). Handyman because I mostly operate independently, preforming all kinds of repair and remodeling opportunities. (+) because I am well connected with reputable tradespeople in the area, and I always happy to discuss larger residential projects; backyard pavilions, outdoor kitchens, shotcrete pools, additions, movie theaters, bars, and wine cellars. My cell phone is (571)320-8605. Do not hesitate to call or text so we can discuss solutions regarding your home’s next repair, remodel, or improvement. With best wishes, thank you. I look forward to hearing from you.

"Sam is very friendly and understanding, ensuring that every step in the process was done correctly, and even did things that he didn't have to do, but he did anyway. He really went the extra mile for me. He's been doing this for a while, so if you're looking for experience, this is your guy. Great technician, highly recommended."

"I have been a customer for a very long time and this scheduled maintenance and dryer vent cleaning was done by Cesar. I have to say he is one very thorough technician and I was very pleased with his inspection and vent cleaning. His service was so different than some of the ones I've had before. I even had one inspector tell me he didn't need to check in my attic which houses one of our two units. Let me tell you about Cesar, he even cleaned up behind my dryer for me. This is something that is rare in customer service. I have my HVAC seasonally maintenanced and never had a inspector be as thorough as him. The pictures he took and explained to me and the one problem he found that no other inspector had found in all this time. I tried to spare him from the attic heat for the repair and have him return on another day in the morning but he didn't mind going back in there to fix the problem for us although it was in the dead heat of the day. I just hope the company sees this review and knows what a good technician they have in Cesar."

FAQs for window a/c unit installation projects in Warrenton, VA

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.
