I have been in the construction businesses for 20 plus years, and can do anything you want. I have worked in many areas of construction for example remodeling spaces, painting, building structures and so forth. I am independent owned.

"Easy communication. I needed a bathroom exhaust fan installed where there is no attic access. The project included wiring and ductwork to the exterior as well as drywall removal and repair, and then finishing everything beautifully. The two-man team of Vasquez did as instructed and also fixed some old shoddy work that was in the way of the new duct and wiring. They used good materials and did good work at a good price. They were also very respectful of my home, keeping the mess contained and cleaning up after. I would hire again."

Hello and thank you for reviewing my profile for a potential project hire. I am a GEC ((general engineering contractor)(veteran US ARMY Civil Engineer)) working on specialized and high-end projects on both residential and commercial areas. Most of my projects are unique and needs a creative vision and an outside-the-box thinker. And you'll be surprised at the fair pricing implemented on each and every job. Feel free to text or call to review your job.

"He came out to put a bottom seal on the garage door, the garage door was working perfectly when he came, he did not put the seal on. He told me I had bought the wrong seal and I need to order a new one, which I did, he said he will comeback when I had the new seal. Before he left, he took the pension table off, he took both of the pension table off and the garage door, rendering the garage door unusable. I called him when I got the new seal, he said he will come out but he did not show up. I called him again and asked him if he was coming out to atleast put the door back and he said no. He told me he could not fix it so he won't coming back out and he told me that I should just call a garage professional. He bragged that he could done it an hour, but he was there for over 3 hours but he never put it. I did called a garage professional and this $100 job which anybody could have done according to the garage door person will cost me $650 to fix it, they cannot fix it because a brand new garage door will cost me about $600 to $1000. He was rude afterwards and made excuses that all of a sudden there were things wrong with my door. I strongly suggest to not work with this person and be very cautious if you have them to come to your house. "

FAQs for window a/c unit installation projects in Costa Mesa, CA

Window AC units can use a significant amount of energy. These units use about 12 to 17 kilowatt-hours per day, significantly more than a refrigerator's one to 1.5 kilowatt-hours per day. To keep your energy costs down, run your window AC only when necessary, keep doors closed to contain the cool air, regularly clean filters and coils, and seal any gaps around the unit to prevent cold air from escaping.

Inexpensive air conditioner units are often not worth it. Low-cost products from popular brands like General Electric, LG, Whirlpool, or Frigidaire may be a reasonable investment. However, putting a small, budget-friendly unit in a large room wastes energy and shortens the life span of the AC since it has to draw more power and work much harder to cool the space. The unit will consume more energy and stress the motor and other internal parts, resulting in early breakdown and costly repairs.

The best deals on window AC units come during the fall when businesses slash prices to clear out old inventory. You can also speak with your local AC installer, who may get you a good deal on a window AC unit since they have access to trade pricing. You can also watch for discontinued products and flash sales in your area.

Window AC repair costs between $110 and $390, with most people paying around $250. Parts cost between $2 and $150, with the rest going toward labor, at around $30 per hour. The occasional one-off repair or a routine AC tuneup cost $75 to $200. Servicing can keep your AC running in good condition for several more years before you need to pay for a replacement unit.

Window AC units last eight to 10 years when installed and maintained correctly. High-quality models last up to 20 years with proper care and routine maintenance. The unit’s longevity depends on its construction quality, regular cleaning, and electrical safety inspections. Keeping the filters and coils clean and addressing minor repairs promptly extends its effective performance and ensures reliable cooling.
