"Called another company I was familiar with but had to pursue them for 5 days! No heat and told it was best to replace the entire unit by 3rd day and they'd order the parts (3 men, 4 hours, & $3k was what I was told). Finally, decided it was too much suffering and temps were dropping. Called Relax Air and he came within the hour, did a thorough analysis. Very professional. The final outcome was one of 3 parts were broken. Also a parts dealer, returned with the parts and tried each one. It was the module, fixed in one day, and for under $1k. He also checked/fixed the humidifier (which said initial company said they did upon initial repair visit and 2 yrs ago for regular maintenance) and adjusted the heating so the house is now perfectly balanced. After 4 years living here, finally no more cold spots!"

"Our AC died last week and the first company provided us 3 replacement options. We selected the middle option ($16,000) and signed the contract, which provided us a 5 day cancellation period. Installation was scheduled for Friday. I solicited other companies quotes using the estimate provided by the first company and all declined stating I needed to schedule an appointment for someone to come out to take measurements, etc. Our inside temperature was 98 degrees. Advanced Environment Solutions provided us an unbinding estimate of $9,600. a better warranty and immediately dispatched a technician to take measurements and install a portable AC unit until the new one could be installed. Our unit was installed Friday. What a bunch of professionals! The team arrived at 6:30 am and were done by 11:00 am. To our surprise, we received a fruit basket from Advanced Enviroment Solutions the following day thanking us for selecting them! Who does is anymore? Hey competitors... Who can top Advanced Environment Solutions??? Need your system serviced or replaced? Advanced Environment Solutions gets our vote!"

"It went very well. After another team had come out and been unable to identify the source of the leak, Nabil (from the HVAC side of the business) was able to correctly diagnose the leak source as the humidifier within about 10 seconds of entering the mechanical closet. Nabil and his assistant corrected all the associated problems within 45 minutes. Both Nabil and his assistant did an EXCELLENT job and brought us some much-needed peace of mind."

"McCrea replaced a 20 year old HVAC system with a new Trane 4-ton XL16i condenser, XV80 furnace and new coils. The salesman, Mark, was very responsive to my request for quote changes or additional items, including financing options. He was very knowledgeable and patient through the entire process as I worked with other companies for competing quotes. As a result of Mark’s recommendations and excellent pricing, I added on a new Aprilaire 1210 filter box (including replacing a portion of the return duct work/box) and an Aprilaire 600M whole house humidifier. I was able to schedule install four days after signing the contract. The installers, Charles and Christian, arrived on time and removed the old and installed the new in about 7 hours. They provided an overview of system operation and cleaned up so well, you couldn’t tell that a significant installation had occurred. I would recommend McCrea, especially Mark, Charles, and Christian to anyone...they were professional and did an excellent job. My home is so much more comfortable with a system that will be better on the summer and winter utility bills."

"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."

"SwiftPro was excellent. When our hot water heater went out (at nearly 20 years old, we were neither upset nor surprised!) we reached out to a few places but SwiftPro was the most responsive and had the price was fair. Zabi, the service technician was fantastic. I can’t say enough good things about him. He was prompt, provided excellent communication, took meticulous care with the work and work space, and was just a great person to talk to. The install went great and there was no aggressive sales tactics or upselling. Just a genuine cut and dry hot water heater removal and install experience. I highly recommend SwiftPro. Thanks Zabi! "

"It was a superb experience. From the visit by Bruce the sales representative to the installation day to the follow-up from Petro, every single person we interacted with was helpful and professional. When Bruce arrived to do the assessment, we spent time going over the heating needs in the house. After a thorough inspection and measurement of the house, we sat down. He showed me a few options, all of which were going to provide good service. I ordered a unit at the end of that meeting. The installation day was just terrific- the entire work crew that showed up were everything I would hope to find: Upbeat, informative, hard-working, focused. The job was finished before end of day as promised. The heater room is now immaculate, with new piping and a new heater. It was like watching a pit crew at a NASCAR race. Everyone had their tasks, they moved carefully but quickly. The materials were all laid out in order, etc. Just a totally professional approach to their work. The crew boss answered any questions I had. The follow-up for a normal inspection of the furnace chimney was scheduled the day after the installation. I’ve gotten calls to insure we are satisfied with the work. Satisfied barely covers it- I am pleased to write this kind of review. Without hesitation I will recommend Petro to friends and family throughout the Philly area. Peter A. Elkins Park"

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.
