"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!"

"Jim is local.  It went great. Jim Ferrell is a professional of the highest caliber. Responded quickly, took care of my problems, and advised me as to better means of protection than I had. He came back a second time to uninstall software that I purchased that did not provide adequate protections and installed free software that would do the job.  He did the work through remote connection, but is available on site if necessary.
For those people needing help on getting red of malware, viruses , etc. on your computer,  Jim is local, better than all thse remote out of state location providers, is a mature, highly trained professional in this area.
If you go to local computer stores you get very young people that can do a basic job, but are no where near the professional level of Jim.
I highly recommend Jim to anyone that needs these type services.

"Tim came out when he said he would, was friendly and courteous.  He diagnosed our problem and proposed a solution.  He patiently answered all our questions and installed the new equipment that very day. In a few short hours we had a functioning water system with much better water pressure than we ever had here before.  We knew the complete price ahead of time. I am extremely satisfied and very glad to have found a good, reliable, and trustworthy plumber who is local.

"The service was great. They gave a lot of really helpful suggestions. They replaced our bulbs with low energy bulbs. They put in weather stripping in areas needed as well. They were great to work with. They gave a detailed report on how to lower our energy usage."

"They did a really good job. They came out on Christmas Eve or Christmas day and fixed the issue with our boiler. They are reliable and the quality of their work was very good. They didn’t have the part for the boiler but knew someone who did. They went and got it from them who happened to be one of their customers. They always clean up after themselves which is wonderful. They are some of the few people that I know in Rhode Island who come over when they say they would."

"They actually cut (very neat) holes in the basement furnace runs to reach up with chimney-sweep type cleaners and powerful vacuums. They also went down every register and cold air return in the house doing the same. What impressed me was that two these guys went way beyond what any technician from my furnace company (who I'd had an annual clean / inspect contract with for years ever did.) I had reported to my contracted techs that my blower fan was making a strained sickly noise for a couple years. They told me just to wait until it died and it would have to be replaced for ~$1,200. They also had told me that my 'state-of-the-art'(20 years ago) Lennox furnace would probably need to be replaced soon. The guys from Affordable Restoration,LLC took out the blower motor, showed me all the dust and dog hair and estimated that is was 90% occluded which was straining my blower motor, plus all the air to my house was coming through all that dust. They then cleaned and lubed the fan as well as an area of similar debris around a/c condenser unit within the furnace.  This clearly had never been done by my service contractors which I find despicable as clearly in their best interest not mine. Yes, the very neat holes were then very neatly patched but will remain easily accessible for future cleanings.The whole process took ~ 4.5 hours and did cost me way over what the cost of the coupon that drew me in, but I also feel that the maintenance they ended up doing saved me a new blower fan (and extended the life of my furnace) as my newly refurbished fan is now purring happily and quietly.  The guys also installed an ultra-violet light system (as used for sanitizing in hospitals). I would've never thought about doing this, but with our allergy sufferers and knowing how devastating a systemic mold problem would be I decided it was worth the ~$500. They also offered a good 'preventative package':  they will come back every 2 years to replace the ultra-violet light bulbs and do the same cleaning for $300. It's too soon to say how much this will help with allergies but to see the amount of dusty debris that is no longer in our system is a relief to me.

FAQs for swamp cooler installation and replacement projects in Stonington, CT

Swamp coolers are quite energy-efficient, using only 15% to 35% of the electricity that traditional central air conditioning units consume. This can lead to significant savings on your energy bills. However, keep in mind that swamp coolers require water to operate and may not cool your home as effectively in extremely hot or humid conditions. When considering overall efficiency, it is essential to weigh both electricity and water usage, as well as the cooling needs specific to your local climate.

Evaporative coolers only work in dry climates because they cool by moistening the air. If the air is already moist, this will have little to no cooling effect. Central AC is a better choice if you live in a humid climate, such as the Midwest, eastern, or western coastal regions.

To install a swamp cooler on a roof, a local HVAC specialist will first find and cut a spot free of wiring and obstructions. They’ll then install metal bracing, legs, brackets, the ceiling duct register, ductwork, power, and thermostat wires. Once installed, they’ll seal all openings, attach duct connections, and install a thermostat. Before leaving, they’ll run cool water piping to the unit and inspect all the connections.

The cost to repair your swamp cooler ranges from $50 to $600, depending on the issue, whether new parts are needed, and the chosen repair service. Depending on the type of pad your system uses, you will need to change out the pads every one to three years for proper operation. When budgeting for the cost to repair a window unit, expect to pay around $230.

The U.S. Department of Energy states that swamp coolers can cool a single room by five to 15 degrees Fahrenheit. However, this largely depends on the size and installation method of the evaporative cooler. You can only achieve these results in a dry climate, such as the American South, as it’s easier to cool rooms in humid environments with central air.

Swamp cooler water usage varies depending on the size of the unit. Smaller evaporative units may use one gallon per hour, while much larger units could use up to 15 gallons of water per hour. Most homeowners can expect their unit to use between seven and 10 gallons of water per hour of usage.
