"From the beginning - Sean was extremely responsive to all of our questions and very flexible with scheduling the service. He installed our new humidifier on the furnace, provided instructions on how to operate it, and offered multiple tips for keeping the system running efficiently. He also offered a very fair price. He was very professional, and we would definitely hire him again!!"

"I can’t say enough excellent things about Lance, the service technician who came out! We just purchased our first home so imagine our surprise when barely a month in the large grand chandelier fell from the ceiling in the early morning. I was going to replace it myself but remembered our home inspection pointed out some instances of aluminum wiring in the house so I thought I should have an electrician confirm the outlet was properly done before I go mucking around in the ceiling. Although it cost me an emergency dispatch fee, they had someone in my house first thing the very next morning. Lance was prompt and just so amazing - very kind and careful with keeping our house clean, taking care of the floors and finishings and really went above and beyond to help a very frazzled young family try figure out the mess they just purchased. While he was at our house we opted to have him also see if he could remove two outlets in the dining room from a dimmer switch so they can be always on. He explained the pricing up front and I knew what the job would cost as a final number before he began any work. For the first job, I was very impressed with how thorough and complete he was in taking care of not just the replacement chandelier, but even with safely disposing of the now broken old chandelier for us! He even offered to help move some boxes for the Salvation Army pick-up we had scheduled - I was just blown away by how kind and helpful he was! For the second job, I was so very pleased that he took the time to really figure out what was wrong. He ended up spending almost three hours discovering several issues - including things like faulty attempts at mitigating aluminum wire connection points in several outlets that we received confirmation prior to settling on the home had been fixed. He was able to come up with creative solutions to safely leverage what was already available to solve our problem and the best part is he really took the time to not only do it right, but to explain everything as he went and really helped me learn more about my house and how I can discover and resolve similar problems in the future. Being someone who is always trying to learn I really appreciated his willingness to answer my questions and share his depth of knowledge and experience! In the end, even though the job was a lot longer than either of us thought it would be, and even though the original cause for the emergency dispatch was already resolved, Lance made sure he stayed until we had a solution in place and we still only paid the initial quoted price! Yes, the price did seem a bit high compared to what I’ve seen on other provider’s quoted rates. However, the work really is just that good - absolutely worth it AND charging by the job instead of the hour takes all of the guessing out of how much you will need to pay, not to mention covers situations like this where the job ended up taking quite a bit longer than originally anticipated. We couldn’t be happier. We were so pleased with the service that we also signed up for their annual service plan to avoid emergency dispatch fees in the future and to get their annual safety inspection. There’s a lot of uncertainty associated with buying our first home, but at least we now know who we will call for all of our electrical needs!"

"From not having a water supply for my whole home bypass humidifier, to having a repaired, new water supply line and instant winter comfort. All in less than two hours. Thanks Edmond and team for getting me taken care of right after I arrived home from work. Wealth of knowledge, too, about HVACs warranties, and other good general advice for first-time homeowners like myself! Glad to have signed-up tonight as a member - eligible for discounts tonight and future maintenance services. Highly recommend!"

"The replacement of my a/c ( with indoor coil) and furnace was handled in an extremely professional way. Holtzople Heating and AC helped me to find the best replacement units for my 20 year old Trane system. I am impressed with the knowledge of the sales person sent to provide quotes. I am also impressed by the skill and meticulous care that the installers took while replacing my entire heating and cooling system. Within a day, they took out my old system, installed the new system up to factory specs, tested and made sure all phases of heating and cooling were functioning as they should, and cleaned up, taking away all of the old unit, leaving nothing behind. The last thing the head installer told me was that a quality control team would be in touch and be coming in within the next two weeks to make sure everything was continuing to operate as it should. This attention to detail, and customer satisfaction is what has impressed me the most about Holtzople Hearing and A/C."

"One of the best contractor experiences we have ever had. Jim called the day before to confirm the appointment. Larry the Plumber was so nice to deal with. He put on she covers to protect my wood floors, worked very neatly and gave us some tips about ongoing maintenance. He did a perfect job. This review us for Petro in central NJ. i was not able to change the company location. We hired them through Amazon."

"THIS COMPANY EMPLOYS EXTREMELY TRUSTWORTHY EMPLOYEES THAT ARE A PLEASURE TO HAVE IN YOUR HOME. THE CARPENTER WE HIRED AT THE SAME TIME WAS SO IMPRESSED WITH THEIR WORK AND KNOWLEDGE, THAT HE HAS USED HIM ON OTHER JOBS HE HAS BEEN HIRED TO DO. THEY ALWAYS CLEANED UP AFTER THEIR WORK, THEY WERE COURTEOUS AND RESPECTFUL OF OUR HOME AND FAMILY, AND WERE VERY PUNCTUAL. SINCE THEY HAVE INSTALLED OUR SYSTEM, WE HAVE NOT HAD PROBLEMS OTHER THAT 'USER PROBLEMS' (I.E., NOT CHANGING FILTERS FREQUENTLY ENOUGH). HOWEVER, WHEN WE DO CREATE OUR OWN PROBLEMS, THEY HAVE RESPONDED VERY QUICKLY TO OUR NEEDS AND THEIR PRICES ARE VERY REASONABLE. I WOULD RECOMMEND THEM TO ANY FRIEND OR NEIGHBOR."

"After several years of shoddy furnace repairs, replacements and guesswork from our propane provider, I decided to find another service. I quickly got a call back and appointment from Tetteris Heating and Air. After a brief diagnostic, Greg Shaeffer almost immediately assessed the problem was a malfunctioning gas valve. After replacing and converting the valve, he discovered that the old valve had not been installed or converted properly by the previous company. Greg was very professional, helpful, friendly and didn't mind answering any questions I had. I couldn't be more satisfied with the work and service that Tetteris provided. Highly recommended!"

"We decided to replace our 16 year old AC and furnace as we wanted to prevent possible problems with our HVAC system. The heating consultant that they sent, Alex H, was very friendly and knowledgeable. He provided us with estimates for a number of options - similar to those from other HVAC companies that quoted for this work. A day later I received a call from Blue Dot offering a discount on that quote and we accepted that quote. Alex made the one and a half hour drive to visit with us again, to walk us through the contract details, and to explain install process. This was a really nice touch as usually contracts are signed electronically these days. The Blue Dot install team came on time on the scheduled day and did a neat and professional job with the install - performing all the necessary checks and tests, and left the work area clean and tidy - and with the HVAC systems working well. The whole purchase and install process couldn't have gone smoother. We are very happy with BlueDot and will certainly use them again preferentially for our HVAC needs."

"Darryl McDowell, the technician from ARS of Laurel, did an outstanding job while performing my AC tune-up/inspection.

As a result of his honest assessments and diligence in addressing all issues in a very comprehensive manner, I feel confident moving forward with needed repairs and/or system replacement. Without a doubt, he provided the best service ever!"

FAQs for central humidifier installation and replacement projects in Mount Airy, 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.
