"My AC failed and I had limited time to find a good solution, I made a phone call to Relax HVAC based on the online reviews and it was a great decision. Nasser came to check the situation, he gave a very detailed and comprehensive overview of the situation and provided with the options I had. I decided to replace the unit, Nasser went above and beyond to find a unit delivery service but there was nothing available over the weekend so this gentleman went for unit pick up himself and finished the installation within a day from my initial call. Moreover, the provided price was very reasonable.I can't be more happy with the outcome and highly recommend Relax HVAC"

The AES Team has 15 employees with 8 trucks to provide quality Heating/Cooling & Plumbing services 24/7. The AES team is committed to hiring and retaining some of the most qualified technicians in the area, with a minimum of 10 years experience. We make training a priority for our technicians and their helpers. We keep the vans stocked with many replacement parts to get you back up and running during our first visit. All of our employees are drug tested, background checked and registered with the state of VA

"Our AC died last week and the first company provided us 3 replacement options. We selected the middle option ($16,000) and signed the contract, which provided us a 5 day cancellation period. Installation was scheduled for Friday. I solicited other companies quotes using the estimate provided by the first company and all declined stating I needed to schedule an appointment for someone to come out to take measurements, etc. Our inside temperature was 98 degrees. Advanced Environment Solutions provided us an unbinding estimate of $9,600. a better warranty and immediately dispatched a technician to take measurements and install a portable AC unit until the new one could be installed. Our unit was installed Friday. What a bunch of professionals! The team arrived at 6:30 am and were done by 11:00 am. To our surprise, we received a fruit basket from Advanced Enviroment Solutions the following day thanking us for selecting them! Who does is anymore? Hey competitors... Who can top Advanced Environment Solutions??? Need your system serviced or replaced? Advanced Environment Solutions gets our vote!"

For all inquiries, please call or text (703) 281-4185. Will not respond to emails or messages through the message center. We have been serving Northern Virginia since 1992. We have Virginia class B license for projects up to $120,000, but will do virtually any project or repair inside you home. We do have a $175 minimum house call fee that includes the first hour of work. After that it is $75 per hour fee for smaller projects. Larger projects are based on a lower hourly rate which is included in the over all project estimate. The cost is generally determined by the job but some areas such as exterior carpentry may be billed hourly due to the unpredictable nature of the work. We may find more work up close or underneath visibly damaged areas. All employees speak English well. We are also able to communicate in Spanish, Cechua or Italian (just in case). We are covered by general liability insurance, disability insurance, workers comp, and heath insurance. I treat my employees and my customers, in the same manner I wish to be treated myself. We have been Angies list supper service award winners for the past 11 years. We care about our workmanship and our customers and I think that is reflected in our awards. Thank you for considering us for your projects.

"Will and his team are knowledgeable and responsive, a trusted contractor! He resolved several plumbing issues and replaced smoke detectors throughout the house."

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.
