"Jeremy, the owner of Parker Home Services quickly - within hours - returned our request for service. He showed up early for the quote appointment. There was no BS. His quote was thorough and accurate. Jeremy removed and replaced the central AC units in a day and a half. His attention to detail is superb. Once the job was done, he brought me over to make sure that the AC worked as intended. While checking vents we noticed that some were not supplying air. Jeremy went back up in the attic and located three supply ducts that had been removed (by previous workers) from their registers and he reinstalled them. He also found a separate supply duct that had a board laying across it, constricting air flow. All of this was above and beyond what the initial job called for and shows that Jeremy takes great pride in his workmanship and making sure his customer is satisfied. We will have them back. Thank you PHS!"

"On time, professional, easy to work with, willing to trouble-shoot and think outside the box to determine the cause of the furnace problem. Had suggestions for further upkeep and service, should the time come. Replaced parts that should have been changed and/or replaced and cleaned by former company, but were neglected for the last three years. Was reassuring that the entire furnace did not need to be replaced!"

"Fantastic. He arrived at our house within 30 minutes of calling him. He evaluated the leak in the basement and quickly told us what was wrong. He had a water tank in his truck and replaced it on the spot. He was gone in 2 hours. He also helped me to clean the faucet filters. We have definitely found a plumber for the future. Highly recommend him."

"Awesome service. They called and texted me to make an appointment for the next day. Showed up during said time. Problem solved what was wrong with our central air quickly. Told us about all of our options and informed us of services they provided but weren't pushy about it. I would recommend these guys and use them for any future needs!"

"At last, a company where Customer Service is an TRUE AND PROFESSIONAL ATTITUDE and not just a department or empty promise. After about a year and during some very heavy rain,I had an overflow from one of my upper gutters and made call to Vista expecting to be either put off with excuses or whatever. I promptly received a call back from Brian, who I believe was the owner, who arranged to come out and inspect the problem, which he did. He identified that the gutters I had on that side of my home,and the steep slant of my roof were not sufficient to deal with flow of a very heavy downpour and suggested I install a 6" gutter and gutter guards. I was expecting to get a large estimate for the replacement of the 28 feet of 6" gutters and guards . I was amazed and grateful when Brian stated that as customer/vendor gesture he would replace everything FREE OF CHARGE. How many companies today would do that?. This job has now been completed . Will highly recommend them."

"I was with Petro for two years under an auto-delivery and service plan contract and found the service is good but the prices are way, way over market.  My real problem is with the initial salesman from "DeBlois" that I dealt with, as the two important questions I asked before signing up were not answered truthfully.  I asked if the price quoted was a promotional price or one typical of future deliveries; I was told I could expect the same levels relative to competition.   However, unlike the first delivery, all subsequent deliveries were at least $.50/gal. above other full-service companies I have used (I checked within a few days of some deliveries).   The second problem is that in my initial call  I asked if I would be serviced by DeBlois or another company, and I specifically asked if Petro would be involved, since as a new resident of Narragansett I asked around and had been warned to avoid Petro.  The salesman at DeBlois said there was no connection, but as it turned out DeBlois and Petro are the same company.  So in sum, I found the service to be competent and courteous, but the prices for both oil and boiler service to be very high.  As I am writing this well after the last delivery, my agreement has now expired and I am no longer a Petro customer.

FAQs for central humidifier installation and replacement projects in Hanover, CT

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.
