"We had an absolutely fantastic experience with X&M Heating and Cooling! From start to finish, Richard was beyond responsive, professional, and genuinely a pleasure to work with. You don’t always expect replacing major home systems to feel stress-free, but Richard made the whole process smooth and even enjoyable. They replaced our AC/Furnace (Condenser, Coil Pack, and Heater) as well as our hot water tank—a big job—and the crew knocked it out of the park. Everything was installed with care, attention to detail, and a clear pride in their workmanship. Richard took the time to explain what was happening every step of the way, which gave us total peace of mind. What stood out most, though, was the responsiveness. Whenever I had a question, Richard was quick to answer, patient, and genuinely friendly—it felt like working with a trusted neighbor rather than just a contractor. If you’re looking for a team that does top-notch work - don't look any further."

"I called to get an inspection done on my AC unit and was quoted $90 for the inspection plus $120 an hr for ADDITIONAL hrs. I ASKED when do I know when the “additional hrs start”, He stated that the tech would let me know once the inspection was done and then at that time he would let me know if there was work that needed to be fixed or if there was nothing then the service would end and I would only have to pay the $90. They charged me $210 for the inspection. I called and requested that we both listen to the call (Because all calls are recorded) They played the call, heard what the rep said and then stated they would get back to me. When I finally reached them again (they never called me back), they stated I would not get a refund, then replayed the call cutting out the part when the rep stated clearly that the service was only $90. They not only GASLIGHTED me, but they altered the recording. $120 may not matter to most but it sure matters to me."

Our highly trained team of licensed and certified HVAC, plumbing, and electrical specialists have proudly served our Northern Virginia area customers for more than 60 years. We’ll show up ready for same-day service in fully stocked trucks, so our work begins as soon as we arrive. And with our 100% satisfaction guarantee on maintenance, repairs, and next-day installations, you can count on Snell to get the job done right.

"I’ve been a loyal Snell customer for years, but this recent experience was deeply disappointing. After our AC failed in August, Snell diagnosed a leaking evaporator coil. We chose to replace the system through them, and the salesperson took time to evaluate the setup in advance. However, on installation day, the crew arrived without the correct ductwork and had to make adjustments on the fly. Unfortunately, the adjustments were poorly executed: • The Aprilaire humidifier was mounted on sloped ductwork rather than a level surface, contrary to manufacturer specifications. • The hole for the humidifier was cut inaccurately. • The drain line was left kinked in multiple places. Aprilaire support later confirmed the humidifier was not installed correctly and warned this could lead to water backing up into the system — a concern I had raised with the installers before they left. Despite multiple follow-up attempts, I received no meaningful response. I was told my concerns would be escalated, but no one followed through. This was a major investment, and I now feel I need to bring in another HVAC team to correct issues that should have been resolved from the start. I’ve recommended Snell in the past, but I can’t in good faith do so now after this experience."

"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"

"Fast service! They came within an hour of my call. Spent over 2 hours diagnosing the problem. Spoke with Trane to confirm his findings. Then came back 3 days later with the faulty circuit board which was covered under warranty. Price was less than I expected and the gave a discount because I am a veteran. I highly recommend this company!!!"

FAQs for central humidifier installation and replacement projects in Ashburn, VA

A crawl space dehumidifier is a worthwhile investment, particularly in humid climates or if you've noticed musty odors, mold growth, or wood deterioration. Though costs range from $3,000 to $9,200, this investment helps prevent structural damage that could require far more expensive repairs later. Beyond structural protection, a properly dehumidified crawl space contributes to better overall indoor air quality and may reduce allergens throughout your home. Consider having a professional assessment to determine if your specific situation warrants this investment.

Addressing crawl space moisture effectively often requires a combination of solutions. A complete approach includes encapsulation plus dehumidifier installation. For minor moisture issues, a basic dehumidifier starting at $1,500 may suffice, while severe problems in larger spaces could require systems costing up to $14,000. The most effective moisture control strategy depends on your specific conditions, making a professional assessment valuable for determining the most cost-effective approach for your situation.

For a crawl space measuring 1,500 square feet, you'll need a dehumidifier with a daily capacity of 30 to 50 pints, with unit costs ranging from $150 to $600. Your local climate and existing moisture levels may necessitate adjusting this capacity—homes in particularly humid regions might benefit from higher-capacity units. Professional installers can measure your specific humidity conditions and recommend equipment that is appropriately sized, balancing initial cost with operating efficiency for your unique situation.

Crawl space dehumidifiers add $300 to $500 to your annual electricity expenses when operating continuously. Energy-efficient models reduce this consumption by roughly 15 to 30% compared to standard units. Most contemporary dehumidifiers feature humidity sensors that automatically cycle operation based on current conditions, helping manage energy usage. Proper crawl space encapsulation significantly improves efficiency by creating a controlled environment that requires less dehumidifier runtime, thereby reducing ongoing electricity costs.
