"Excellent experience working with Andy and his AJB Mechanical team to get my heat pump unit replaced on short notice. Everything was done on time and in a very professional manner. They took the time to explain what all needed to be done prior to and during the install so that there were no surprises. Once done they took the time to explain how to operate the new thermostat. I wouldn't hesitate a bit to use Andy and his team again should the need arise in the future."

"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."

FAQs for central humidifier installation and replacement projects in Maryland-line, MD

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.
