"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."

Thank you for choosing H K & S Plumbing Co.! We are committed to providing quality workmanship and superior customer service to all of our existing, and future, clients. We strive to maintain our reputation as a high quality, service oriented company. No job is too big or too small. Call today!

"Very disappointed. This guy is a crook. I paid way too much for what he did and he did not do the work properly. He replaced pipes that were leaking from our upstairs shower. I had another leak a few weeks after he did the repair. 2nd leak was not related to the pipes he repaired, but the 2nd plumber who came out for the 2nd leak had to cut into the ceiling where HK&S Plumbing replaced the pipes and told me that the work was not done properly. He did not glue the pipes properly and he used a rubber coupling that is not allowed in California. The other plumbing company said they would fix his work for 65% less than what I paid HK&S. When I asked HK&S about all this, he gave excuses about the small space and how much more work it would have been to do the work the right way. When I asked him again for a refund, he is now saying his work will last "forever" (really?) and has nothing to say about what he did wrong. He is not giving me a refund. Not sure I will use anyone thru Angi again."

Heating and Air Conditioning questions, answered by experts

Set your house temperature between 55 and 85 degrees Fahrenheit while on vacation, depending on the season. If it’s winter, don’t go below 55 degrees. In the summer, the best AC temperature for energy savings is no higher than 85 degrees. You can save anywhere from 10% to 15% on your energy costs by adjusting the temperature while you’re away. If you have a smart thermostat, set up vacation modes for each season. On your way home, turn off vacation mode to allow the home to warm up or cool down before you arrive.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.

No. HVAC, which stands for heating, ventilation, and air conditioning, includes all of the systems that work together to regulate a building’s temperature and humidity levels. In comparison, air conditioners only provide cooling. You can have an air conditioner as part of your HVAC system, but not all HVAC systems include air conditioners.

Yes, running your air conditioning unit too cold can cause condensation in the air ducts and built up moisture on the air filter, resulting in a breeding ground for mold and mildew. Mold and mildew growth can irritate those with respiratory issues, so it’s best to keep your AC running at a normal temperature.

This is a bit of a trick question. Even though the seasons arrive at the same time every year, the weather doesn’t always behave according to the calendar. So, while it’s fair to say that you can expect to turn on your AC starting in late May or early June, it all depends on the outside temperature and how cool you like to keep your home.
