"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. "

"Bill and Trish exceeded the expectations I had from the start. Trish is so pleasant to talk with that you forget quickly you are asking for a service and not talking to a friend. Bill is a craftsman who has many years of experience and he gets right to the point of where your problem lies. In our case the tune up for the summer was not realistic when our 30 year old AC unit had leak issues. Bill and I worked through several scenarios regarding cost of a repair and an investment in a new unit. It made sense to do a new unit and not worry about our old AC unit further breaking down and requiring more repair. Bill and Trish advised us of a cancellation that allowed the new AC unit to be installed 3 days after the service call. Bill and Trish followed through on their quote, and arrival time for installation on time. Everything I was told with a time frame was on time,accurate, and made sense to what I was receiving. Raphael and Nisho were assigned my install and they were no different regarding their punctuality and care for our house. Bill and Raphael took me through the complete process of what would be done and when the project would be finished. Raphael and his crew treated my house well making sure to drop cloths down everywhere they worked. I could not tell they did anything because of the cleanliness in which they worked. The job was made easier as Raphael helped me to clear the work area I was supposed to clear. I was running late in clearing and Raphael helped me to clear the area without complaining or having me do it on my own which was my job. After the installation Raphael walked me through our new AC and also provided valuable recommendations on how to take care of our new unit. What I must stress is everyone from Cool Air Technologies goes above and beyond what they need to in making sure you are 150% satisfied. Raphael helped me pick quality new air filters for our AC on Amazon to make sure we knew exactly what to purchase. Bill followed up that afternoon to ensure I was satisfied and encouraged any questions I might have. The AC unit performs exceptionally. The old unit if I turned it on in the afternoon to cool the house it could only drop the temperature by a degree or 2. Our new unit brought the temperature down from 78 in the house to 74 degrees in less than an hour. We still have 30 year old ducts and vents that do not allow the best air flow so this is a great improvement. Bill installed a new AC that cost me $3,000 less than what I was quoted 2 years ago from another company. My wife and I are extremely pleased with the service provide by Bill, Trish and his crew. I love they are family owned and they have your best interest at heart when they come out and do a job for you. Please use Cool Air Technologies for your service needs. It's such a pleasure when you get to deal with honest hard working local family owned companies that take pride in their work and word they give you."

"Initially I considered having to pay $8000-ish for a replacement unit. Robert Alfonso saved the day, however. Well trained by LA Tech, and professional from start to finish, Robert diagnosed and resolved my wiring and capacitor issue quickly. The fix was $485 not $8000 to replace the unit. These guys are legit. Great result. Robert "Doctor" Alfonso rocked it."
This is the outdoor unit that offers 17 SEER Hyper efficiency and super quiet operation of 54db's compared to 80 plus on older units
notice the low profile, this is about 14 inch wide instead of the traditional 36 wide.
This replaces your old gas heater

"The installers showed up promptly within the window they gave us, they replaced the upstairs ducting and installed dampers to balance the air (one room is a lot warmer because of the sun). We had multiple quotations and they were significantly better than the rest. This did solve our issue completely!"

Customers say: True professional

"We found McCormick home builders through Angie’s list. They were not one of our original contacts, but they contacted us and came out to give us a quote. Matteo was extremely helpful, informative, honest, and gave us reasonable realistic prices, and did not try to inflate the prices or pressure us in anyway. We felt very comfortable with him immediately. We felt like he was a member of the family that we could just talk to and ask questions he was very personable. He gave us his contact number in case we had other questions and he was always available when we needed him for any type of questions or concerns. Mateo‘s team did a beautiful job. They were fast. They were efficient. They cleaned up beautifully. They did a wonderful job. They were very considerate of our time our needs and our neighbors. They were an absolute pleasure to work with. I would highly recommend Matteo from McCormick home builders for any home building projects, and we will be calling him again in the future!"

FAQs for window a/c unit service or relocation projects in Mission Viejo, CA

If your window air conditioner is relatively new or of high quality, repairing it can restore optimal performance and protect your investment. However, for older units or those with ongoing issues, it might be more cost-effective to replace the unit to ensure long-term efficiency and reliability. Consider the unit's age, the severity of the problem, repair costs versus replacement, and energy efficiency ratings when making your decision. If repairs cost more than half the price of a new unit, replacement is typically the better option.

Window air conditioners last eight to ten years on average. After this time, you may notice decreased efficiency and component wear. Replacing an older unit can improve energy savings and provide updated features like remote controls and better overall performance. With proper maintenance including regular filter cleaning, coil checks, and professional servicing, you can maximize your unit's lifespan.

If your portable AC isn't cooling, it might have a refrigerant leak or a circuit malfunction that's preventing it from working properly. It's best to contact a local air conditioner contractor to inspect and repair the unit. If your AC is older and repairs don't fix the issue, replacing it might be the most effective solution.

Removing a wall-mounted AC costs $55 to $75. Completing the removal yourself at the end of each summer season, being sure to do so according to proper guidelines, keeps you within this cost range. Should you require professional assistance for removal and disposal, if you can't move the unit yourself, expect an added fee of $25 to $50 to the overall cost.
