"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."

Family owned and operated. Our crew has worked together for 20 years. We provide you with the highest quality systems. Our installation and repairs are always done right. Call today.

"I worked with Charles and honestly his attitude and assurance that I?d be working with him sold me on they?re company Well after I signed I never seen Charles again no finish walk through with the client just job is done where?s the money. 26,767.50 for new furnace and a/c I expect an attic access to be finished properly and with quality materials. As you can see they can?t get a mitre corner completed properly. And then use construction grade plywood material NOT good finished grade. So I?ll do it myself the right way. I wonder if Mr. Pelle?s home is finished in junk material like this. If they can?t do this properly who knows what else is done poorly. Another thing the workman asked where I?d like the thermostat I pointed at a location. Well he just starts drilling away and hit a metal vent. Being in design build and construction I know to scan the wall with a stud finder that shows where pipe elec, etc are. Now there?s a vent in a wall with a hole. Zero follow up!!!?"

Heating and Air Conditioning questions, answered by experts

It’s never a good idea to run your AC without a filter, even just for a night. The filter defends your HVAC system from the dust, dirt, debris, and other grime in your home. Without a filter, those contaminants are more likely to get inside your system and potentially damage it. 

Keeping your air filter clean is crucial for your heat pump's efficiency. As a general rule, you should check your air filter every 1 to 3 months. However, the actual frequency might vary depending on factors like the type of filter, indoor air quality, and the amount of dust and debris in your area. If you notice the filter is visibly dirty or clogged, it's a clear sign it needs attention sooner. Regular filter maintenance ensures proper airflow and helps your heat pump perform optimally, keeping your indoor air fresh and comfortable.

There are several tell-tale signs that your AC coils need cleaning, including:

  • You’re getting higher electricity bills.

  • Your home doesn’t feel as cool as it usually does.

  • Your AC unit is running longer than usual to cool your home.

  • Your home is more humid than usual.

  • The coil is covered in frost while running.

You should plan to change your AC unit's filter every one to three months, depending on the manufacturer's recommendations. You should also clean the coils at least once per year, but if you have pets or someone in your household has allergies, you might need to clean them more often. Fortunately, many pros will clean the coils and change the filter for you during an inspection, which you should schedule once or twice per year.

Repairing an AC unit is usually more cost-effective than replacing it, but you should consider the age of your system. Most central AC units last around 15 years, and window units last for between eight and 10 years. If your central AC is more than 10 years old or your window AC is over six years old, you should consider replacing the AC unit rather than repairing it. The repair will fix your issue, but you’ll likely save money in the long run by replacing it rather than repairing it only to replace it a few years later.
