"My experience with him was top notch. He was accommodating to my schedule. I work nights and he was willing to come to my home in the early evening instead of normal business hours. He assured me the fix of the leak would hold until the end of summer but there was a chance that I may need a new unit next summer since the unit is over 10 years old and the leak was pretty severe. I had no other trouble with the unit the rest of the summer. His price was reasonable and he was friendly and efficienct. If I need a new unit next summer I will definitely use Tetteris Heating and Air for the replacement."

"I usually have my landscaper, brother or some other random person power wash my deck, rails and pavers. I decided to step it up a notch by hiring a professional. Mel was AWESOME. Contact was swift, bid was fair, scheduling was easy. Most importantly, I cannot believe how much better he did than an “average” person with a power washer. Everything looks brand new. Honestly, I’m shocked. I own several homes and I’m very picky about my contractors. I recommend MEL whole-heartedly. Plus, I love hiring an independent contractor. Good for him for making a business successful. Don’t look any further; Mel is your guy."

"The contractor did a quick but thorough job repairing each electrical outlet and provided advice on how to maintain them properly. The ring doorbell installation was quick and neat. The contractor wore a face mask at all times and we had a completely contact-less visit (including the bill payment - we were able to "sign" via our own devices). This company was a pleasure to work with."

"Jim was in the area here in Nashville, and I spoke with him about my computer. He was extremely knowledgeable about everything computer related, and seemed very familiar with the problems I described having with my computer.  I also had a very old fax machine that I was manually having to scan documents and fax them, over and over again. Sometimes, even the same ones. Jim advised me on what kind of printer to get, as well as what type wireless network to get and even went with me to Staples to purchase the items (That was over and beyond the call of duty in my opinion). I am a business owner for a trucking logistics company, and my computer is my livelihood, so I really trusted that Jim would get my system working, and help me with my scanning and faxing issues.



Jim arrived on time, and got to work right away.  He took the time unbox my printer, set it up for me, he also set up my wireless network, and the entire time he helped me understand exactly what was going on.  He showed me how to set up my wireless, how to make changes to it, he even went through the manual on the printer with me, and showed me how I could scan documents directly to my computer and save them....and then just fax them out all from my computer!  He then started cleaning out some of the toolbars and bad software I had inadvertently installed, then he ran the virus scanner, still showing me how to do it myself, and explaining to me how I could avoid these issues in the future.  I have to say I have never had such excellent customer service from a computer repair person. He removed the viruses, and even offered to put a remote software package on so that if I ever have any problems in the future, he could access my machine remotely, and help me fix them, essentially saving me the cost and time for the future.



I would HIGHLY recommend Jim and North Alabama Technical Services for any and all computer work. Jim was an absolute pleasure to work with, and again, I've never felt so well taken care of with my computer issues before. If I could give him all A+'s I would.  I have seen a recent review that mentions that he takes advantage of businesses, but he only charged me $75 and gave way more than that in service. I really appreciate him for all he did for me.

"Mike and his crew installed a new oil fired furnace and central air conditioning. The low ceiling in our basement required Mike to come up with a duct design that no other vendor could match. The whole installation was done in one day. Mikeà ¢à  à  s crew were very efficient and friendly. Also Mike was the low cost bidder. I highly recommend Tettris."

FAQs for central humidifier installation and replacement projects in Unionville, MD

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.
