"We had ATC take a look at our HVAC system that was not running well. Another company came out and told us the entire installation was wrong and everything had to be replaced, including all ducting. The price was astronomical. They also said that some structural work needed to be done, such as cutting through drywall and the house, which was not included. When Kevin from ATC came out to look, he said the ducting and the heater were just fine. The condenser and coil were old and probably should be replaced but it wasn’t an emergency. He suggested installing a dual controller and an additional return to improve the airflow issue we were having. He also gave us a quote for three options of new condenser/coils, along with financing options. The price was a fraction of the other company and the financing allowed us to do everything now rather than later. John and Kevin came out to do the installation. THEY WERE PHENOMENAL! They arrived on time, were so pleasant to speak with, were exceptionally patient with all our questions, were extremely knowledgeable about HVAC and split systems, were neat and clean, and did an extremely professional job of installation. That included all the drywall work that was necessary! And the improvement we received was unbelievable! Every room in the house was immediately receiving excellent airflow! We really thought we were in trouble, but these guys made sure we got all the cooling/heating we needed throughout the house with as little cost to us as possible. I would highly recommend the company and would especially recommend John and Kevin. They also fixed a split unit that wasn’t working. They can do it all!! Love these guys!"

Cal Climate is family owned and operated, bringing a personal touch to everything we do. In 1970, founder Andrew "Andy" Sauer started the company with a simple vision - provide friendly, reliable service and products. Andy knew that Cal Climate would succeed by building a reputation based on going the extra distance. His sons, Tom and Bob, continue to carry on that awesome tradition today. We take pride in the fact that 90% of our new business comes from referral's. Please if you have any further questions or you would like to schedule a service call or a free installation appointment please contact us

"This review is long overdue, but I need to praise Calclimate for their excellent service! Tom and Chris were professional, reliable, and provided quality work. Tom replaced my father’s AC unit last summer on a short notice and provided much needed relief for my father, who was physically impaired at the time. I highly recommend Calclimate and will definitely use them again!"

Heating and Air Conditioning questions, answered by experts

To make the most out of your AC, consider implementing the following best practices: 

  • Choose the right size AC for your home to ensure your unit runs as efficiently as possible.

  • Choose a window with shade, as direct sunlight can cause your AC unit to overheat. 

  • Clean or replace the filter at least every two months. 

  • Inspect the AC’s fan and straighten it if necessary. 

  • Discontinue use immediately if you suspect a malfunction, as running the AC while broken can lead to significant issues. 

  • Turn off (or adjust the temperature) when you leave the house.

While 72 degrees is a comfortable setting for many people, it’s likely not the most efficient temperature setting for your air conditioning unit. By pushing the temperature up to 75 or 78 degrees, you stand to save money on your energy bill. That said, these temperatures may be too warm to be comfortable for some people and are definitely too warm for most people to sleep comfortably.

When your HVAC technician mentions recharging your home AC unit, they’re referring to the process of topping off the unit with refrigerant, so the levels are properly maintained and pressurized. Normally, a properly functioning AC unit doesn’t need additional refrigerant, but AC units can develop leaks or other problems that decrease the amount of refrigerant needed.

Look up your model number online to find additional information. Usually, you can just take a look at the old filter and find the brand name and dimensions to order a new one. When replacing the filter, always check that it’s pointed the right way to match the direction of your airflow. Many filters have arrows on them to help with this step.

If your AC refrigerant is low, you may notice that the unit takes longer than usual to cool your home or that your energy bills are higher. You may even feel a warm breeze coming from the vents when the AC refrigerant is low. Don’t attempt to check refrigerant levels yourself. Only certified AC repair pros should check and refill refrigerant.
