"The repair went great. Greg Pullins set up the service for me. Brennan was the service repairman who came. I asked him to replace my smoke detectors with new ones (which I had purchased ahead of time), which he did, and he was able to take care of the bathroom exhaust fan by cleaning it out way up in places I hadn't been able to get to myself, saving me the cost of buying a new one. No more chirping is coming from my smoke detectors, and my bathroom fan is working and sounding like it should."

"Advanced heating and air solved our problem of an uncomfortable sunroom. They offered solutions, options, and information about a great system that was new to us...the Gree mini-split. We chose the Gree. The indoor components were slim-lined and fit right in with the room. The best part is that they were whisper quiet. (Also the outdoor opponent). The technicians were courteous, knowledgeable, and efficient. Thank you Advanced heating and air for making our sunroom livable and enjoyable. Reg and Linda Jellicorse"

"Overall, we were very satisfied with the knowledge and quality of work that Covenant LLC provided. We had Covenant LLC install a radon mitigation system for our basement. Initially my husband and I met with David for the estimate and consultation. David spent the time to explain how radon can get into the basement, what the system would look like, and how he was going to make sure it was working. After meeting with David at Covenant, we met with a competitor who were definitely not as knowledgeable, were not going to seal any of the cracks or holes in the foundation or even follow industry standard by venting through the roof of the house. The day of install the crew was personable and professional and if they had any questions, they asked. The 3" pipe that Covenant had to install to run through a closet and into the attic. In order to do this, they had to drill through the porcelain title floors and run through 3 shelves. They spent extra time to jig-saw cut the shelves around the pipes and they took special care not to crack any of the porcelain tiles and when finished it looked like it was built with the house. After completion, Covenant came back and tested the radon levels which were reduced to below their guarantee, which itself is orders of magnitude below the EPA limit. We were probably not the easiest clients to work with as we had Covenant move the roof penetration several times until the noise was completely unnoticeable. David was always polite and professional and he wouldn't be satisfied with the job until we were satisfied. We highly recommend Covenant Air to anyone who is considering these services."

"Overall, it was a good experience. AAA put down a vapor barrier and installed a Santa Fe dehumidifier with sump pump. The result is that we can now use the stand-up basement/crawlspace to store things under the house without ruining them. This is the part that you need to know. The installation was not without problems. First, they broke an A/C drain pipe, second, they cut a sprinkler controller wire while running a PVC pipe. Here's my take, accidents happen but how does the business respond to these issues? Well, Donna was very quick to send her team out to correct the problems and they even paid for the damage to the sprinkler system. To me, that's top notch customer service. Any business can make a mistake, but how they handle it is the mark of a good company. Every time I lift the roll door and go into the basement now, I'm amazed at how cool and fresh the air is down there. No more mildew and no more smell."

"The tech was really nice and did a good. They were suppose to install a carbon monoxide detector but have to wait to see how many they needed to order. They have not returned as of today. Left area clean."

"When we had our oil changed at Jiffy Lube back in July, the technicians there brought a problem with the rear differential to our attention.  We took the car to Sal at Meineke, who repaired it within a day at the price mentioned above.  
However, this isn't the main reason for putting him on Angie's List today.  What I'm really impressed with is what happened in September 2012.  We noticed a funny sound in the engine and took the 2007 jeep to Sal at Meineke.  He thought it was a problem with the transfer case and knew this would be very expensive to replace  (around $2500).  Sal told us that he wasn't absolutely certain that he was diagnosing the problem correctly.  With our permission, he offered to drive our car to another nearby business that specialized in transmission problems.  He said that he trusted the people at this business and would like to get another opinion before he made this costly repair.  We agreed, and the other business was able to repair our car for about $1100.  We were very grateful to Sal for his honesty and willingness to go out of his way to spare us such a costly repair.  Even though he didn't get the job, Sal saw to it that we were given honest and capable service.
Sal is reliable, conscientious, and trustworthy , and I want others to know about him!

FAQs for central humidifier installation and replacement projects in Knoxville, TN

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.
