"It was a superb experience. From the visit by Bruce the sales representative to the installation day to the follow-up from Petro, every single person we interacted with was helpful and professional. When Bruce arrived to do the assessment, we spent time going over the heating needs in the house. After a thorough inspection and measurement of the house, we sat down. He showed me a few options, all of which were going to provide good service. I ordered a unit at the end of that meeting. The installation day was just terrific- the entire work crew that showed up were everything I would hope to find: Upbeat, informative, hard-working, focused. The job was finished before end of day as promised. The heater room is now immaculate, with new piping and a new heater. It was like watching a pit crew at a NASCAR race. Everyone had their tasks, they moved carefully but quickly. The materials were all laid out in order, etc. Just a totally professional approach to their work. The crew boss answered any questions I had. The follow-up for a normal inspection of the furnace chimney was scheduled the day after the installation. I’ve gotten calls to insure we are satisfied with the work. Satisfied barely covers it- I am pleased to write this kind of review. Without hesitation I will recommend Petro to friends and family throughout the Philly area. Peter A. Elkins Park"

"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."

"Everyone from Presidential has been friendly and helpful -- great customer service! Glenn came to our home to discuss options to replace our furnace (fuel oil) and AC systems with a heat pump. He immediately understood that we were looking for a heat pump eligible for the new tax credits (unlike another company, who only provided estimates on what they had in stock). He prepared the estimates for 3 different models on site, and he noted that the heat pump eligible for the tax credit would cost about the same as an older model (unlike what the first company told us). We were able to schedule installation quickly, and then the adventures began. Harvey and Andre were here for 12+ hours...because a wire was either never connected at the factory or came loose during shipping. We also had to replace a defective line from our house to the unit. While it was a complicated install (not the fault of Presidential), we rec'd great service from hardworking staff members. Highly recommend!"

"I actually found them on Angie’s List. He is punctual. I used to use somebody else and I was always standing at the door looking at my phone, looking at my watch to see if he is going to show up on time or not. The driver for Lisa’s is generally at my house five to ten minutes ahead of time waiting for me."

"Kurt and his team at American Home Services did an absolutely amazing job.  They are very committed and honest.  Unlike other companies I got quotes from, they do not use scare tactics.  I had two separate mold jobs done, which I will describe below:
1- Visible mold in basement:  They start by totaling sealing the room in plastic and running air scrubbers constantly so there was no cross contamination.  His team helped me go through each item, hand by hand, determine if they could be cleaned or needed to be tossed.  This took a full day, and they literally looked at each photo, book, piece of furniture, etc. with me.  I was able to salvage more items than I thought would be possible.  They then went to work removing the damaged dry wall and floor molding (which poetically had mold on the back of it).  After disposing of the damaged items, they sprayed down all the walls, floors, ceilings, etc. with non toxic cleaners.  By throwing away all the contaminated items, and cleaning everything that remains, the rooms are now mold free.  They don't do the build-back, so you will need to get a handy man to install new dry wall, etc.  Now that the mold is gone, his solution for the problem to not arise again was practical and cheap:  run a dehumidifier to keep the place clean.
2- Non-visible mold in kitchen:  Coincidentally, the weekend before Kurt was to come out for the above long-standing issue, I had a major water leak in the kitchen.  The possibility of mold never crossed my mind.  However, Kurt told me how water gets under the cabinets, will not dry thoroughly, and then grow mold from the inside.  I ended up calling my home insurance company, who resisted ripping out the cabinets.  Kurt fought them on my behalf and got them to agree.  I first had the cabinets removed by a different firm hired by the insurance company.  American Home Services then performed mold remediation similar to my basement - namely rip up the damaged items (floor boards in this case), use the mold cleaning solutions and then dry everything with huge dehumidifiers since the sub flooring was still wet from the leak.  I'm so glad Kurt kept pushing for this.  I had our inside air tested by an independent firm and it counted 9,000 spores 3 days after the water leak and 200 about a week later, after remediation.  If not for Kurt, mold would have been growing under all my kitchen cabinets.
In summary, Kurt and his team are extremely honest, very thorough and everything they do is of great quality.  Their cost was reasonable compared to the other quotes I got.
If you have mold issues, my first suggestion is to do something about it quickly.  It won't get better on its own.  Give Kurt and American Home Services a call."

"They are excellent. We've used them for 30 years. They have done just about anything and everything we've had to have done with the car. 

Their price was $59.98 for the service, not including the price of the battery. And they gave me a senior discount. Compared to what other people say, I think they are probably fairly ordinary in the pricing and they are always giving me a senior discount or something. So I am pleased with the price of everything. 

They have immediate response. I've used them for 30 years and I'm not changing now."

"Vinh did an excellent and thorough job. He noticed the bathroom sink valves (previously replaced) had one valve knob missing, which he highly recommended replacement of both valves. The removal of old faucet and new kitchen faucet/sink install was hard work but done quite well. Once main water was turned back on, Vinh made sure the new bathroom valves and kitchen faucet had no leak issues. All was done perfectly. Will hire Jiffy again."

FAQs for swamp cooler installation and replacement projects in Damascus, 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.
