"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.

"They came, they diagnosed the problem (which wasn't in the air conditioning), they told me how to fix it, and then they left...after having refused payment!!!!! i thought i must be living in the 1950's in a small town!!"

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

Florida rooms can have heat or air conditioning, although not all do. These rooms can be added to the existing HVAC system or use a mini-split system, or they may just use a ceiling fan or the breeze from the windows for cooling. Florida rooms with air conditioning often have glass windows to keep the cool inside instead of just mesh screens.

You can adjust uneven airflow in your home by adjusting the dampers on the vents. However, if the temperature feels consistent throughout the home, don’t worry too much about uneven airflow. Generally speaking, larger rooms should receive more airflow than smaller rooms, especially if they only have one vent.

If your central AC is not blowing cold air, you should try resetting the system. Many systems have a reset button. Make sure your thermostat is off, then turn off the circuit breaker that powers your AC. Hold the reset button for three to five seconds, then turn the circuit back on. Set your thermostat to cool and choose a temperature cooler than the room. Your system should turn on quickly.

On average, an AC unit lasts between 10 and 20 years. However, the specific lifespan depends on the type of unit, how often it's used, the local climate, and the quality of maintenance. Central AC units typically last 12 to 17 years, while window units have a shorter lifespan of 8 to 10 years. Portable AC units last about 5 to 10 years, and ductless mini-split systems can last up to 20 years. To extend the life of your AC unit, it's important to perform regular maintenance, such as replacing filters, cleaning coils, and scheduling annual professional tune-ups.

An AC inspection costs anywhere from $75 to $200, while a full HVAC system inspection that includes your furnace ranges from $200 to $450. While there's a cost to a home AC inspection, it can save you hundreds or thousands in the long run by catching problems, avoiding breaks, and saving you money on your utility bills.
