"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!"

"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

No, you should not run an air conditioner with a Freon leak. If you think your AC unit is leaking refrigerant, shut it off immediately. When you keep using a leaky air conditioner, it could damage the unit and release more refrigerant. After turning off the AC, have an HVAC pro come take a look at the unit.

Yes, you can potentially save $60 to $200 by handling your own air conditioner capacitor installation. However, capacitor replacement comes with the risk of electric shock. Only attempt this if you have the knowledge and protective gear to carry it out safely. Otherwise, we recommend hiring an HVAC pro with the experience to properly diagnose the issue and avoid damaging other parts of your AC unit.

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.

A home AC unit provides anywhere from one-half to five tons of cooling and requires approximately two to four pounds of refrigerant per ton of cooling. At approximately five to 10 minutes to fill one pound of refrigerant, a home that requires three tons of cooling will take about six to 12 pounds of refrigerant and approximately 30 minutes to two hours to completely recharge the unit.

If your AC suddenly stops working, the first thing to check is your thermostat settings. Ensure the thermostat is set to the appropriate temperature and mode (cooling). Sometimes, a simple adjustment or replacing the batteries in the thermostat can resolve the issue. If that’s not the issue, look to see if the circuit breaker tripped. These basic checks can often identify simple fixes before you need to call for professional assistance.
