"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"

"The BEST phone call I have made this year for a service needed in my home was to Mirsky Heating and AIr. I called in the middle of a So. Cal heatwave because my thermostat had stopped working and I needed to replace it. How often does an AC company, in the middle of a heatwave, tell you they can come the same day? NEVER!! Except for Mirsky..Darrow told me that he would try to make it work..and he did...which I will be forever grateful!!! He checked in with me during the day to assure me that he was coming and not to leave work until he was more clear on the time he would be at my home. He showed up with another Mirsky employee named John..they were both super friendly and so helpful. Darrow found the problem and within 45 minutes, the thermostat was replaced and everything was up and running again. I can't say enough how grateful I am to Darrow and Mirsky Heating and Air...I am giving their contact info to all of my friends and will be calling them again for anything heating AC related."

"Setting up the appointment was easy. They offered to come out the next day but I needed to wait until Friday, my day off. Mike showed up on time. Did a good professional job removing and installing a new 50 gallon water heater. Mike also tested my water pressure and noted it was too high. For an agreed upon small additional charge he replaced my pressure regulator and a shut off valve."

"Never having had air vents cleaned before I was a little unsure of how it actually worked and have nothing to compare this to.  I liked B very much, he was very helpful on the phone and while he provided the service.  He offered good suggestions and tips.  He seemed very professional, arrived when he said he would and finished an hour or so sooner than he thought he would.  He was responsive to questions before during and after and seemed to know what he was doing.  He did spend some time in his truck talking on the phone but I did not feel it impacted the service he provided.
The amount of dust raised by this activity drove me out of the house for over an hour.  We all developed bloody noses over the next few days although I ran the ventilating fan for well over two hours.  I am assuming that this is a normal part of having vents vacuumed out with a giant hose but I was not prepared for it!  I don't think that this was the fault of the service provider but it would have been nice to know before hand which is why I am posting this here.
The price was high but not out of the range of what other providers quoted to me and seems to me to be appropriate given other quotes.  I give $$ a B only because 3 days after I had the work done there was a deal for the same work for about $300.

"Joe was terrific. I called several companies and he had the best deal in town in that he did not try and sell me a bunch of stuff, but instead offered to service my HVAC and come back in 6 months for one low price. He also installed 2 new smart thermostats for me. He called me right back. Scheduled an appointment right away and showed up on time. The thermostats I had purchased (ecobee) were new to him and he honestly told me that but said he could handle it and he did. Plus he is a very nice family man to work with. Definitely use him again."

"Jim did a great job. He quickly assessed the problem and then took our unit with him to work on it more. When he got back to us, the fix would have cost more than it was worth. He gave us options for a new or refurbished PC. We felt the refurbished was a good deal and chose that. He came back and set that up and we are very happy with it. He then took a look at my laptop and again took it along. He tuned it up and installed a speed upgrade we wanted. Of course, we paid extra for the new unit and upgrades, but we thought the price was very fair. Jim seemed very knowledgeable and responsive. We will definitely call him again if we need any computer services."

FAQs for swamp cooler installation and replacement projects in El Segundo, 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.
