"I chose them because they had the highest number ( and score) of reviews, but after the service was provided I believe those reviews were fabricated. I am a new home owner and decided to try your services. I did not know much about duct or vent cleaning but after what I saw yesterday I decided to do some research online and that is when I realized I did not receive the services I thought I was paying for. Only 1 technician came with a small shop vacuum and a brush, and he was not able to do most of the work because. 1. We had Fibreglass ducts and he said his equipment was not suitable to clean this type of duct and that it would damage it. So he only "vacuumed" the area that his arms could get to, and did not examine the vent for damage or recommend any way to clean or fix the fiberglass. 2. He did not want to take the vent covers off the ceiling because he said he did not want to damage the sheetrock, so I'm not sure how he cleaned them. I think he only sprayed air into and around the vent 3. He didn't have any air filters with him, so I had to go out and try to buy them. They did not have the size I needed so I spent 1 hr driving around looking for them and could not see what he was doing at home. 4. They did not seal any of the vents nor did they have a negative pressure machine. He did not hook up to the main vent and told me he accessed it with a brush through an intake, which means that they did not fully take out all the dust from the main feeder. At first I was ok with his explanation, fine but then after doing research I realized that all he did was stick a brush in the room vent but did not seal the whole system, nor did he take off and clean the main duct. 5. He said he cleaned the dryer vent from Inside and Outside but I did not see any signs of him going outside as it was raining and he would have had to get the machine wet. 6. He had no other equipment other than a shop vacuum with a 4 inch hose. I'm not sure how deep he was able to get with that into the dryer vent. I really feel as if the work performed was not done correctly, and my ignorance was partly to blame. This company certainly did not have the right equipment to do the job and they didn't even use the correct procedure to seal the system to create a vacuum. This was definitely more of a $300 dollar job at most and not $600 dollars like they charged me."

"It did went well. I did like, there was a gentlemen that came out that was very professional I thought he did a nice job. Well I think the only criticism I had is I guess he went around and essentially evaded the house. I guess I was just probably expecting a little bit more than just kinda putting out bait traps. He was very professional, he was very nice so nothing bad or critical to say about the individual they sent he was very respectful and professional. I guess just for like overall service I guess I was just expecting more."

"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!"

"It was GREAT from start to finish.  The head of the company came out to do the estimate, and provided a very clear explanation of how the work would go and what our options might be.  They measured a nd ordered the windows, and scheduled the install for the specific dates we wanted.  When the date came, they did the work in a single day, and were professional and careful throughout the process.  All along, their office communication was clear and they were responsive and helpful.  The windows look wonderful and I think they will make a big difference in energy efficiency.  It was a terrific experience, and I'd highly recommend Vista.

"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 Thompson, 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.
