Aleksandar Kastamanov has been in the residential construction business for the last two decades. Please get in touch with us for any of your bathroom, kitchen or major renovations and we can help. Covering Lafayette and Orinda.Call us today!

"Generally, I refrain from writing reviews for companies unless they perform their work beyond my expectations, Kastamamanov Construction happens to be one of those companies. Aleksandar Kastamanov and his son Aleks are both Perfectionists and men of good character they both demonstrate a willingness to work with you to address any concerns that arise during the project, they do quality work at a very competitive price, they are easy to work with, *accommodating and go beyond basic requirements for the sake of quality, safety, and stability. During the inspection the county inspector kept saying things like,* good job and most guys do not take the time to do that , referring to the qualify work they had done. They both demonstrate attention to details and invite input of ideas to see that you are happy with their work. This deck that Aleks replaced for me I built 50 years ago so I know what it takes to build a structure that will last through many years of use. Well, having watched their work from beginning to end I can tell you that Aleksander and Aleks have constructed a beautiful deck for us that is built to last for many many years. Attention to detail started when demolition began and lasted throughout the project until the final strand of stainless steel railing was installed. If you want a new deck or an old deck replaced there is a lot of contractors to choose from around but, if you want your project done right, done beyond the bare minimum required according to your City and County permits, and built at a very and competitive price, Kastamanov construction is the company for you. Aleksandar and his son Aleks are both men of integrity and good character, they are both easy to work with skilled and knowledgeable. Any future projects that I have, both interior and exterior will include a prejudiced request for a bid from Kastamanov construction."

FAQs for window a/c unit installation projects in Concord, 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.
