"David Gray installed my heat pump sometime ago. I have always signed up for the maintenance packet. A guy came out and found a non-working part. It seemed to be working properly but wasn't. Kevin found the nonworking part. Then William installed the part and I see a difference in the comfort level. They ordered the part and within 48 hours had it installed. I have 10 year parts and labor so this cost me nothing. Kevin saved me a ton of money. I am impressed with their customer service and have used them for over 17 years now. Kevin found the problem and William completed the repair. Teamwork! Thanks fellas! I - and my family - appreciate all your good work!"

"Old AC quit and we thought it just needed a charge. Called 1 hr heating and ac, set appt for next day. The tech was on time very professional and honest. Our system was completely empty he advised us that the price to completely fill the system was about a grand and told us it is our call but ultimately the system has a leak, he could fill it and charge us the price and be without ac not much longer than a season if we were lucky. We chose to just replace the system. The sales rep was out here on time the next day he was also very professional and nice, then at the end of that meeting we were lucky enough to be able to get the AC installed the very next day which was Friday. The install guys were great also! They arrived early to my surprise which I was happy about. I was quoted about 6 to 8 hrs for install and the install team was quick 4 and a half hrs later new system was in and running great. It was a wonderful experience for such a large task"

"I was confused because of the name difference between FAST OF FLORIDA, INC. and the plumber from ADVANCED AIR HOME SERVICES. I wasn't sure of who was coming to my house or phoned. HOWEVER, Paul Ryan the plumber from Advanced Air was excellent. Professional, caring and explained everything and gave me my options going forward. Definitely will call them if needed - they just need to explain the difference in company name when phoning!"

FAQs for central humidifier installation and replacement projects in Saint Johns, FL

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.
