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."

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."

"They charged $98 to come give me an estimate for swapping our a shower valve cartridge, which was fine, but the pricing they provided was completely unreasonable, $1,000. They were unwilling to provide any detail for the price. I ended up buy the part myself for $30 and replaced it in 30 minutes."

Swamp cooler installations and replacements FAQs
Generally, a swamp cooler only uses 15% to 35% of the energy that a traditional central air conditioning unit utilizes. However, swamp coolers also require water and may not cool a home as effectively as an AC unit. They’re more efficient in terms of electricity usage, but when you factor in effectiveness and water usage, it's tougher to argue which unit is more efficient.
Evaporative coolers only work in dry climates because they cool by moistening the air. If the air is already moist, this will have little, if any, cooling effect. Central AC is a better choice if you live in a humid climate, such as the Midwest or eastern or western coastal regions.
To install a swamp cooler on a roof, a local HVAC specialist will first find and cut a spot free of wiring and obstructions. They’ll then install metal bracing, legs, brackets, the ceiling duct register, ductwork, power, and thermostat wires. Once installed, they’ll seal all openings, attach duct connections, and install a thermostat. Before leaving, they’ll run cool water piping to the unit and inspect all the connections.
The cost to repair your swamp cooler is between $100 and $300, depending on the issue, if you need new parts, and who you choose to do the repairs. Depending on the type of pad your system utilizes, you’ll need to change out pads every one to three years for proper operation. When budgeting for the cost to repair a window unit, expect to pay around $200.
The U.S. Department of Energy says swamp coolers may cool a single room by five to 15 degrees Fahrenheit. However, this largely depends on the size and installation method of the evaporative cooler. You can only achieve these results in a dry climate like the American South. It's easier to cool rooms in humid environments with central air.
Swamp cooler water usage varies depending on the size of a unit. Smaller evaporative units may go through one gallon per hour, while much larger units could exceed 15 gallons of water per hour. Most homeowners should expect their unit to use between seven and 10 gallons of water for each hour of usage.
