"I’m quite happy with the results of our AC unit install. There was some miss-communication within the company that caused some delays, but our AC replacement installation was really difficult in having to go thru the roof inti a tight space. Once the techs realized what the nature of the job was, they did an epic job. I had 4 or 5 business previously that didn't even offer a bid for this job. ARS beat the only other two quotes offered. I recommend them highly."

"I contacted Bluestar Air Mechanical for a second opinion after an appointment with Air One. I have a Carrier HVAC system, and the Air One technician recommended a complete system replacement, claiming the blower was bad, the furnace control board needed replacing, and that there were other issues. Since replacing the HVAC is a big investment, I wanted to get a second opinion. It was only after comparing the service from Bluestar that I realized Air One may have been pushing for a new system sale or lacked the expertise to properly diagnose and repair the actual problems. Isaac, the technician from Bluestar, spent about an hour thoroughly diagnosing and fixing the issues. He found burnt wiring in the furnace and discovered that the wrong capacitor had been incorrectly installed in the AC. Isaac replaced the burnt wiring in the furnace and the capacitor in the AC. After these repairs, my Carrier system was back up and running—without the need for a costly replacement. Bluestar, and Isaac in particular, demonstrated professionalism, expertise, and honesty. They focused on resolving the actual issues instead of pushing for an unnecessary system replacement. I highly recommend Bluestar for their reliable service and Isaac’s thorough and knowledgeable work."

"From the estimate appointment (Mark) to the install (Charles, Christian and Justin), McCrea employees were professional, courteous, punctual, responsive and hard working. It was an all day job. The work areas were left clean. Charles explained the install and systems to me before leaving. New A/C seems to be working great. Heat hasn’t been used yet. McCrea handled the permits and product registrations. Gwyn communicated with me promptly after the install regarding both."

"

we had a leak problem and the tech came and looked over our equipment, fixed the problem and left. It cost us nothing and we have had their home heating service contracts for over 20 years.  They have NEVER ONCE not shown up or not helped and in the two furnace emergencies we had--they were here with in 1hr. 

We are very happy.

"Oullette's team was able to complete the installation in two days and haul away the old units. The new system is much more effective with consistent temperatures throughout our home. As well, it is much more efficient with demonstrably lower electric bills. We wholeheartedly recommend this company."

"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."

"By far the most professional and customer friendly company I found after an exhaustive search to replace a single zone high wall ductless system. They responded without delay and were able to perform the work the next day. The Service representative who did the survey for a quote (Nick) was very knowledgeable, understood what I was looking for and provided a quote accordingly. I felt he was looking after my best interests instead of selling me something I did not need or want. The installation team (Dara and Charlie) were on time, customer friendly and did excellent work. I am now a big fan of this company due to their excellent customer interaction and quality work. Job well done."

FAQs for central humidifier installation and replacement projects in Fairfax Station, 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.
