"Although they provide a time frame for service, frequently they are late or have to re-schedule. When ARS installed my furnace, they provided a humidifier as well. However, the humidifier is not included in the maintenance contract, and any work or filter change on the humidifier is extra. The cost is almost as much as the maintenance contract. They used to answer the phone asking how they could provide exceptional service. No longer do they ask that. Makes sense, because they do not provide exceptional service. Also, the technician seems to want to convince you to buy additional equipment, which may or may not be needed."

"Although the AC unit was working, it was leaking water. I had another company come in and tell me that the main drain pan was cracked and that it would cost $2880 to repair or I could buy a new unit costing over $8500 dollars. I called Relax Air for a second opinion. Kamal and his crew came out the next day and confirmed that the drain pan was cracked and leaking. His repair cost? $400. I also had him do two other HVAC related jobs while he was there (replacing AC disconnect box and installing a water float switch]. They had everything done in and hour and a half. Total cost: $675. Kamal is fast, efficient and most of all honest. I would recommend him to anyone."

"Aside from installing a new Carrier gas furnace, they installed a state-of-the-art thermostat. The comfort specialist, Chris B., was very responsive and helpful in helping me decide what to buy, as well as providing help after installation. The two installers, Chris M. and Justin B. were very personable and very neat during removal and installation of the furnaces. Overall, very satisfied. Very commendable job."

"TC HVAC showed up on time, were professional, did what they said they would do at the price they quoted (which was better than any other company) and the system is working wonderful. I will use them again when we are ready to replace our water heater and A/C unit."

"The HVAC stopped working on one of coldest days in the winter. Joe immediately send IRE within 30 minutes!!! IRE was great, he fixed the system for an extremely reasonable price. We told him that we were going to replace the system and he gave us a great quote. IRE was so pleasant and professional and we definitely wanted him to do the work. He installed a wonderful system in one day!!! I highly recommend IRE and JDL HVAC they are the best."

"My AC unit was misbehaving. I called Snell after being told by another contractor I would have to replace the indoor and outdoor unit for ~$8k. Italo walked me through the diagnostic process, explaining every detail (I asked him to) and I learned a ton. The other guys were not interested or possibly not equipped experience-wise to repair the unit. Italo was incredible. I will be calling these guys when my HVAC system eventually dies. I never felt like he was trying to pull one over on me."

"It went very well. They did a good job. The cost was over $400. I don't know whether or not that's too high or not. I seldom have plumbers in so I can't say the cost was high, although I was surprised it was $400, but that could be the going rate. He seemed very agreeable and very happy. I needed something and he was happy to get it. He was very knowledgeable and helpful in that regard. As for the quality of their service, so far so good. Everything went okay. It stopped leaking."

FAQs for central humidifier installation and replacement projects in Alexandria, 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.
