Beltway Air Conditioning & Heating is locally owned & operated out of Hanover, MD. We are Lennox Premier Dealers & are BBB accredited with A+ ratings & reviews - We provide services & installations within a 50 mile radius of home base. Our team specializes in installing and servicing heating, cooling & ventilation equipment, whether it is a small A/C repair or a commercial rooftop - our team is trained to take care of all your HVAC needs! We bring extensive experience and professionalism to every home and commercial building. Our work reflects our passion! The Best Price + The Best Work = Your Best Value. We have uniformed & well-trained staff that under goes background checks and drug screening upon hire and randomly. All of our service professionals are also licensed to work in the state of Maryland.

"We are a bit disappointed by Beltway. While we do appreciate some of their efforts in trying to remedy the situation, the overall experience has been quite negative. Please see reasons below: 1. A brand new HVAC system that was installed on Wednesday completely failed by Saturday morning - which was less than 3 days of installation. This calls into question the quality of Beltway’s product or job, or both. 2. Weekend messenger centers have been extremely frustrating and unhelpful, basically saying that Beltway does not serve customers during non-business hours and that customers just have to deal with Beltway’s issues on their own. We called 4 times this weekend out of desperation. Yet each time they showed no sympathy on the fact that our baby has been suffering through the 80 to 90-degree heat trying to nap. 3. A weekend technician was finally sent on late Sunday afternoon (thanks to owner’s stepping in); however his timing messed up weekend plan as one of us had to stay home and completely missed our good friend’s son’s high school graduation party (now people at the party learned about Beltway…). 4. Unfortunately, this weekend technical was unable to solve the problem and decided to leave us with 2 portable cooling units, which, unfortunately, were extremely loud and inefficient in cooling down, so most of us weren’t able to sleep, just like the night before. Felt like all of their products that we’ve coped with in the past 5 days have been nothing but disappointing. 5. Finally, the full crew came on Monday. But their timing here again messed up the baby’s nap schedule - as the upstairs system was right next to the nursery. This is our first time hiring Beltway. The amount of inconvenience and frustration that they had created in the past 3 days was unbelievable. The experience has been quite negative from multiple aspects, calling into question not only their customer service ability/arrangement but also quality of their products and jobs. We don’t know if we can trust Beltway again or hire them again."

If you are looking for a HVAC Contractor, a Plumbing Contractor, or an Electrical Contractor to provide you with great service, you've come to the right place. We provide heating services, air conditioning services, plumbing services, and electrical services to our customers in Frederick and the surrounding Counties, the Pan Handle of West Virginia, and Northern Virginia, from our offices located in Frederick MD. With 3 generations of experience in providing heating, air conditioning, plumbing, and electrical services, we are dedicated to providing the best possible products and services for you, and your family.

"Tri State was prompt—they had a tech out within hours when our 20-year-old HVAC broke down. The repair estimate was $800–$1,200, and they also sent a salesman, Mike, to discuss replacement. Mike was courteous and knowledgeable, but, when we sat down to review the quote, the sales process turned into a bad car-buying experience. They started at $34,000, then "discounted" to $29,300—$10,000 -$12,000 higher than other quotes for the exact same unit. Even factoring in their warranty, they remained $8,000–$10,000 overpriced. Mike also claimed they were a four-generation family-owned business, but I later found out they’re owned by Sila Services, a Goldman Sachs private equity firm—which feels misleading. To their credit, canceling was easy (though I hadn’t signed a financing agreement or put money down). Bottom line: Get multiple quotes. Their pricing was excessive, and the sales tactics felt manipulative."

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.
