"I found Anderson Heating and Cooling when looking for someone to complete annual maintenance on our aging heat pump. I was impressed with the representative that came out (I completely forget his name). My wife and I have been saving for a while to replace our current HVAC system (installed in '93). We decided to go forward with things this Fall and, in preparation, I arranged five companies to give estimates. I had some good (and not so great) experiences) but kept coming back to Anderson. The price was right and the owner, Steve, was low-key, knowledgeable, and straight forward. I'm happy we chose them to install replace our system. The installation appointment was incredibly smooth and I was never pressured or upsold. There were no surprises and the price was exactly as estimated. I hope to enjoy a lot of low-to-no maintenance years to come with our new system, but I will definitely be using Anderson for my future needs. I highly recommend them as a company."

"I live in Tucson Arizona andI just want to say that I haven’t had any work done by J&M, but if I lived in the Oregon or Washington area I wouldn’t consider anybody else. I’m trying to get an underground gas line installed. I searched all over the web and found J&M, and after reading everything about Jeremiah and his company I emailed him a question. He called me back and thoroughly explained all my different options and was extremely polite professional and a pleasure to talk to. He even referred some companies in the Tucson area for me to contact. In this day and age it’s a pleasure to find a company and somebody like Jeremiah who has that kind of integrity."

"One tech, Jacob Bailey, did a thorough testing and servicing of the A/C and then reviewed immediate and future concerns about the system. He made recommendations about further diagnostic testing and a recommendation about the likely need to replace the blower capacitor. Will Adams found a leak in the instant hot water dispenser and said it needed to be replaced. He suggested options for Roth doing the entire replacement and install or purchasing the unit and then having it installed Both techs were clear in their presentation of what needed to be addressed and offered options without any pressure."

"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."

"Estimator arrived on time and checked 49 year old A/C and gave quote on new unit as well as repair. We authorized replacement and a date and cost was given, work was done on time, installers were very professional and friendly. Would have liked itemized bill that showed cost of each item, but would use them again. Very happy."

"Jared is fantastic! Super prompt scheduling & thorough communication right from the start. He was able to come out much sooner than I expected. He was running a little later than he thought on the day of the appointment & let me know right away, which was fine. He is very personable & knowledgeable, and his work is efficient & clean. No surprise costs, everything was as previously agreed to. Even though I wasn't paying for the furnace or A/C to be cleaned he still took the time to look at them & show me what he found, for future reference. The whole cleaning process only took two hours, and we got to see how filthy everything had been plus the random objects he'd found in the ducts. As a new homeowner of a 'light fixer' I was relieved to have such a painless experience! I am SO GLAD we had this service done and I would hire Jared again or refer him to friends & family in a heartbeat. Highly recommended."

"I expected the cleaning technique would be the truck-mounted negative-air vacuum process. However, Aegis uses the point of contact method, removing vent covers and inserting the vacuum. The tech was very friendly. We did a walk through to view the number of air ducts to be cleaned and to be certain all necessary furniture and items were moved to allow clear access. He cleaned all of the air vents, the furnace and the dryer vent. There was a considerable amount of debris in the air vents as we bought the house new, and the vents hadn't been cleaned to remove dirt and debris from construction. My only complaint was that the tech said we didn't need to move a chest in the hallway above which the air exchange was located. He did move it later without my knowledge or help, and explained afterwards that one of the legs of the chest broke as he re-positioned the chest.

FAQs for swamp cooler installation and replacement projects in Gaston, OR

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.
