"Not only did Tyrone install both thermostats. But he saved me money. When you buy a smart thermostat there will be a notice stating a C-wire is required. Tyrone installed both of my smart thermostats without the use of a C-wire. So I was able to return them and get a refund. Both thermostats are working flawlessly! I highly recommend Tyrone if you live in the Baltimore area! Thanks again Tyrone!"

"01/28/2021 I called in the morning and left a voice mail message explaining I needed a main shutoff valve replaced. I received a call back from Vernon about 2 hours later and he asked me when I needed it done; this week or next week. I told him I would rather have it done this week but I could wait until later if necessary. He said he had 3 or 4 jobs scheduled for today and if they all went smooth; he may be able to do it this afternoon if that was ok. I said that would be great if he could. Vernon called me later in the day an said he could do it now if that was ok. He said he would be there as soon as he finished rapping up the job he was on. Vernon was there in a little while and looked over the job and explained what he was going to do. He did an excellent job and cleaned up when he was done. Vernon is pleasant to deal with and did a great job."

"I was impressed by how hard working and thorough the workers were. They hauled the old gas water heater out and got the new one installed promptly and did a neat job. They reconfigured an awkward gas pipe near my washing machine, replaced an exterior gas hose with a UV resistant one, and checked all gas piping including our gas fireplace. We were very pleased with the end result and appreciated the fair pricing. Highly recommend."

"Very easy to work with and excellent quality work. Wanted a Bradford White hot water heater to replace an old unit. Received quote and arranged installation via email. Scott arrived on time and completed the installation. Installation was clean and professional. I would highly recommend."

"Our office needed a replacement water heater installed. Heil was very responsive to my multiple emails and calls. We did have to pay an additional fee of $250 to expedite the replacement due to the water heater not being currently available in their personal inventory. So far, we are pleased with the replacement. The price paid was almost a third of what other companies estimated."

"Don (the owner of Aqua) was in the area at the time I called and was able to stop by within 60-90 minutes of my call. He checked operation of the boiler, and diagnosed the problem with the help of the boiler manufacturer tech support. I needed a new ignition control module; the problem was that the boiler flame would not stay lit. He tried to get the old one working again, and seemed to succeed, but I called him back the next morning to report it started acting up again. He ordered the part and returned after it arrived in a few days to install it. The part appeared to resolve the issue and I was good to go. The boiler is over 25 years old and my previous HVAC contractor had said it needed to be replaced. Don looked at me like I was nuts when I told him that. He genuinely believed in repairing rather than replacing if at all possible, and I could not agree more."

"I claimed a deal online for a hvac tune up for $75 (or $85, I can't really remember). When they came out, the guy admitted it was his first week on the job. The hvac unit was old so he said it wasn't really worth him doing to tune up but he could give me a quote. Even though he couldn't do anything to help the unit, I still got charged. As a result of that, I decided to go with another company for the installation."

FAQs for swamp cooler installation and replacement projects in Baltimore, MD

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.
