"McLay Services did an excellent job on the preventative maintenance for my A/C system. Dylan was professional, courteous, and thorough throughout the visit. He replaced two air filters, cleaned the coils, and checked all electrical components to make sure everything was running safely and efficiently. My unit is now healthy and fully operational. I really appreciate the quality of work and attention to detail — I'd definitely recommend McLay Services to my friends and family!"

"Their technician, Justin came out and assessed the situation, quickly discovering the true source of the problem: the wire bundle that connects the system with the thermostat on the wall and been chewed through by rodents apparently, and this was causing the system to quit. He offered to replace the wiring and do a service on the roof mounted AC condenser unit, which we agreed to. Total cost was a fraction of what we had paid the previous company to not even discover or fix! We would wholeheartedly recommend the services of this excellent company."

"HD Mechanical did an excellent job. After trying to fix my water heater, the tech offered me two solutions, the first to repair the old unit and the second to replace it. I chose to replace the unit because it was 20 years old. He was able to return in two days and spend many hours at my home. The tech was courteous, professional, explained everything and made sure everything was working properly before he left."

"I own a laundry and needed two new swamp coolers. I called DNA and Andrew came out and from our first meeting was very professional. He was knowledgeable and able to answer all my questions which put me at ease. These guys did a bang up job. They were clean and made short work of removing my old units and installing of the new ones. I would highly recommend DNA for future work."

"Cal Climate Corp had been keeping my very old ac system alive for the past 3 years at a reasonable price and with excellent service. Bob and Tom are honest and conscientious so when the time came to replace the entire ac system, I was happy that they were available to do the work...particularly in the midst of another sweltering Southern California summer. The quoted price was much less than I anticipated, the work was completed in one day, and I was perfectly comfortable leaving them to do the work unattended. I returned home to find my home as clean as when I left it...and, thankfully, much cooler. I recommend them unreservedly."

"Dave was very efficient and knowledgeable. He was able to supply my quote before he left. I look forward to working with Southland heating and air. Follow up: I made my decision and signed the contract. Best decision I could have made. They were thousands of dollars less for the exact same equipment than 3 other companies I got estimates from. When challenged none of the other companies could revise their estimate to even come close. Southland is a Mitsubishi diamond dealer so I got full Mitsubishi warranties plus 1 year from Southland of parts and service. The day the installers arrived, on time, it was raining. Jamie and Ricardo used the utmost care to protect my home. They covered the floors, moved and covered the furniture and made sure before they left that I fully understood how to use the remote and operate the equipment. I have attached a photo so you can see for yourself the way they carted for my home. The equipment works perfectly. I would hire this company again in a heart"

FAQs for swamp cooler installation and replacement projects in Altadena, CA

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.
