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."

Central humidifier installations and replacements FAQs
Aim for indoor humidity between 30% and 50%, with the sweet spot around 45%. That range keeps mold, dust mites, and musty odors in check while protecting drywall and woodwork. Staying in the zone also helps your HVAC system run more efficiently and supports healthier air for you and your family year-round, during hot summers and cold winter months.
With routine filter changes and coil cleanings, most whole-house units run for eight to 15 years. Heavy use, poor air quality, or bargain-bin equipment can shorten that span, while a well-maintained, high-quality model often makes it to the upper end of the range. Ask your installer about recommended service intervals to get the most mileage from your investment.
It depends on your climate. Homes in cold, dry regions can often shut the dehumidifier off once winter sets in. If you live in a warm, humid area—or your house tends to trap moisture—you may need to keep it running year-round. Use a simple hygrometer: if readings stay below 50%, give the unit a rest. Just remember to restart it when humidity climbs again to avoid mold and condensation.
Dry air feels cooler, so your AC doesn’t have to work as hard. By stripping out excess moisture, the dehumidifier lets you raise the thermostat a few degrees without losing comfort. A shorter AC runtime reduces electricity use and can shave a noticeable amount off your summer power bill. Energy-efficient models further enhance those savings.
If your home is under about 2,000 square feet, a well-placed portable unit can handle the load. Just remember they’re less efficient and need hands-on upkeep—think emptying tanks and cleaning filters. If you prefer set-and-forget convenience or plan to expand your living space, a whole-house model still offers better long-term comfort and lower energy use per square foot.
