"I used to like them. Use them for my big install of backup basement sump pump. This time, I was out of the country, my rental property in MA needs a toilet fix. It was a standard water tank leak and we need to replace the inside mechanism. Milltown came and said 'rebulid the toilet', my wife authorize them to do it as I was not reachable at the time their plumber was at the rental property. They were in and out according to my tenant for at most 45 min, rebuilding two toilet tank and fixed the leak. The bill came to be 1200, $600 a toilet. One line item on the receipt is $470 for the kit they use to replace the plastic mechanism inside the water tank. I casually google the kit, I can get a universal sup kit for the toilet to replace that for $20. I called them, manager came on gave me that talk - we did hundreds of toilet leak and we average all of them to come up with the cost for that line item, which includes (a) parts (b) labor (c) our service guarantee for a prompt and reliable service Say they charge $200 /hr labor, 1 hr for two toilet is $100 labor for 1 toilet (remember, the plumber was there like 30-45 min rebuilding the two toilet). Say total parts are $100 (with markup), we are talking about $200 for fixing the leak of 1 toilet. They charged almost $600 for one toilet. You can do that math. I expect some up charge, but I am not paying $300 just for getting prompt reliable service. I turned around and asked for a few reliable plumber quote from Thumbstack with great reviews, most can do the job for $200 labor and I can get them the universal kit they will be able to come on the same day. So maybe if you want Milltown to do bigger job, that is ok. For smaller job, it does not worth it. Replacing the toilet flush mechanism is really not rocket science in plumbing. If I am not thousands of miles away, I would have done it myself after watching some Youtube video. I am willing to pay up charge for the service, but this is really above and beyond the normal up charge range, $1200 for a 30 min job replacing the toilet flushing mechanism in the water tank!!"

FAQs for swamp cooler installation and replacement projects in Waltham, MA

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.
