"RJ Groner it’s a very reliable company. They are extremely professional, they care about the quality of their work, they replaced a boiler for me, other contractors wanted to be replaced my entire system. They repair what was needed. RJ Groner took care of everything in the right way and not only my system works perfectly they maintain it every year. Additionally they are 24 seven available for a last-minute need at a very reliable and affordable rate. I 100% recommend their service. "

"Great! Keith, Bunnie and their team are professional, pleasant and knowledgeable. They communicate, they are on time, they work cleanly and go the extra mile for service questions. They do not rush and Keith makes certain the customer is pleased with the progress and workmanship. In the Fall 2021, I had the heater replaced and just this past month, 2022 I had AIRCO return to do the air conditioning installation. I own an older home and it required a little extra TLC which Keith planned for and made adjustments as needed. I highly recommend them for any services ...."

"I was very impressed with the customer service provided by Tara at RPB HVAC. She called me soon after I placed my request on Home Advisor and walked me through everything and was also available after typical business hours. This was great since I'm typically not out of work until after 5:30 pm. She communicated with me every step of the way, either by e-mail or phone, and explained the costs before any work. I think we spoke on a Wednesday and they were out on Friday morning (due to my tenants' preference) and had already replaced the aging water heater by Saturday morning. I was very pleased with their customer service and prices. I will definitely hire them again in the future."

"Joe found that there was mold in the duct work. It was enough that the duct work had to be replaced. It could not be cleaned. Even after spending a fair amount of time, Joe told me that the cleaning was not enough. He said he would not charge me for his time. He was so nice about the situation that I did him some money for his time. He also followed up to make sure the replacement went well. I would recommend G&T for any duct & dryer vent cleaning for residential or commercial use."

FAQs for central humidifier installation and replacement projects in Allentown, PA

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.
