Now offering 10% discount to Seniors over 65 and Veterans! Free over-the-phone estimates!

"Hercules Handyman Services did a great job installing the oven/stove. Lano did a great job in handling the problem from beginning to end. He immediately returned my phone call, contacted the tenant, investigated the problem, followed up with me (giving me the options to move forward), disposed of the old oven/stove and installed the replacement. I contacted the tenant, and they were happy with Lano's work. Lano was efficient and the cost was reasonable for the service provided. I will use Hercules in the future as they provide excellent customer service. "

RC&G is an acronym - it stands for "Richard, Charlene, and the Girls", because it's a great reminder of what I'm working for. I'm Richard and my wife and daughters are the most important thing in the world to me. Also hugely important to me is doing great work in my business as a handyman. I've always been mechanically inclined and good at fixing whatever's broken. With decades of experience, now I'm truly a master handyman. Whatever you need, I'm here to get it done. I respond quickly to contacts and give an accurate estimate. Then I arrive as scheduled, do the job right, and leave your house as clean as I found it. I'm looking forward to meeting you!

"Project went fine. Richard was very professional and accommodating!"

Albert Nahman Services was founded in 1981 and has been serving Berkeley, CA and it surrounding areas in all their plumbing and HVAC needs. Each of our technicians went through rigorous training so we can guarantee that you will be receiving the proper service. We are also insured and supply a warranty for our parts for five years and up to twenty years on an re-piping or sewer replacement. Call us now to make your appointment!

"The plumbing technicians came out as promised to assess the leak. They were both very courteous and kind and assessed the damage. I am giving three stars because they estimated the cost to be almost 250% higher than what the actual cost was to fix the issue. I am sure there are customers out there that would just accept any bid however, please get multiple beds for these projects, especially when working with this company as they will inflate the cost to take advantage of the situation. I ended up only paying for the $79 estimate."

"Called this company for their $77 dollar, which they advertised with a flyer, for a tune-up and cleaning for my heating system. They are a Hayward company and I was told that our Castro Valley home was not in their service area. I bet if I called to buy a new heater they would be out in a day."

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