"Service man arrived as expected and performed the annual maintenance of the air conditioning system. The work was thorough and it was something that was familiar to me as I used to do in my younger years. With heavy use of airconditioning in the summer in CA, this is important and something we do every year.

Hydro jet uses water at 4,000psi to clean the inside of the mainline drain which connects all the home's drains to the city's sewer system.
Using a snake we can go through the cleanouts on the side of the house.
With the cleanouts snaked, and the blockage located, we can send the hydro jet through the sewer vent and flush out the blocked drain.

"Did a great job...it was a very long day from start to finish however. They did a great job of keeping everything as clean as they could since our attic access was in the master closet! Yikes! Really made a difference and our house stayed much cooler with the fan and new insulation!"

"Eric Young came to my house to provide a quote to replace my furnace. My usual HVAC guy told me it needed to be replaced. While Eric was checking it out I asked if he could troubleshoot it and tell me why it wasn't working. He said for sure. So, I asked him how much. He said $69. I said do it. In less than 5 minutes he found what was wrong and fixed it! Wow. He told me the romex connector on the motherboard (that my HVAC replaced) was installed backwards so there was no power going to the furnace. That saved me thousands of dollars it would have cost had I listened to my HVAC guy! He's not my HVAC anymore. Eric Young is. He was thorough, efficient and pleasant to work with. I will contact Baker Electric from now on if I ever need their service again. I highly recommend them."

"35 year old plastic covered ducts that had deteriorated in 35 summers of attic heat were removed and replaced by new Kevlar covered insulated ducts in one morning by Tony and Daniel. The attic was very cramped with tight corners, but the team triumphed. Shelving that had to be removed was replaced, all floors and stairways were covered with drop clothes, and all old ducts were sealed in plastic bags and removed. The price for the work and the newer and more long lasting duct materials was very reasonable."

"I never give reviews but Same Day Heating and Air Conditioning absolutely deserves one, From Start to Finish they were professional, respectful and courteous. The Customer service Representative was accommodating with my busy schedule and was able to send a Tech out later than usual to meet me right after work which I was so grateful for since My kitten and I have been freezing!! I ended up running a little late but my technician Sean was understanding and was such a nice guy. Sean was professional,informative and thoroughly explained all my options to me without being pushy, I've had such bad experiences with Service companies in the past trying to pressure me into buying something or replacing something right away but he didn't do any of that. Hands down best Customer Service I've ever received. Same Day will always be my go to for any of my HVAC Needs. Thank You Same Day. My kitten and I Thank you!! We will never go anywhere else!! :)"

"I recently had a new HVAC heating and air conditioning system installed by Javier and his son Gene and even though a good friend of mine recommended Cano, the entire experience exceeded expectations from start to finish The level of professionalism was immediately apparent. Javier arrived on time, communicated clearly, and treated my home with respect throughout the entire process. What really stood out was the time they took to walk me through all of my equipment options. They didn’t just push one system—they explained the pros and cons of different setups, efficiency ratings, long-term costs, and what would work best for my specific home and usage. I felt fully informed and confident in the decision I made to select Cano over the other 2 quotes we were given from other companies. Their attention to detail was impressive. Every aspect of the installation was handled carefully and methodically, and they double-checked everything before wrapping up. On top of that, their cleanliness wa"

Heating and Air Conditioning FAQs, answered by experts

It depends on how fast an HVAC technician can resolve the issue. First, if there's a refrigerant leak, you’ll want to keep small children and pets out of the house. Next, you’ll want to turn off the AC unit to ensure no more freon enters your home. Finally, you’ll need an AC technician pro to come to your home and fix the leak immediately. Ultimately, it’s best to leave your home if you discover a freon leak—the risk of exposure is very high, and it’s not worth risking your health to stay.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

A frozen coil can cause permanent damage to your HVAC system and lead to costly repairs if not fixed. It can cause the unit to overheat and also cause the compressor to fail. It’s vital to turn the unit off if the coil is frozen and address the issue as soon as possible. 

Fixing a leak in an AC unit costs $200 to $1,600, depending on the type of leak and any related damage. But depending on the age and condition of your AC, it might make more sense to replace the AC unit instead of repairing it. If your AC is only a few years old and relatively problem-free, then repairing it is the right call. But if it’s nearing a decade old and has other issues, consider replacing it.

While many states do not have specific licensing requirements for HVAC companies, your local city or county might. It's always a good idea to check local requirements online and use a tool like Angi’s contractor license lookup to confirm that the company you’re considering is licensed. Regardless of licensing, you should always ensure the company you hire is fully insured to avoid potential lawsuits if a technician is injured on your property. Additionally, it is recommended to check if the company holds third-party certifications, such as North American Technician Excellence (NATE) certification or R-410A certification, which qualifies them to work with HVAC refrigerants.
