"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.

"I was really impressed with the service provided by Nadav and he is team. I have a thirty year old home that still had the original HVAC systems. One located in the attic and the other underneath the house. Neither of these installations was simple. The Sky Clean Air team quoted me two days to remove and install new systems. The install crew was really professional, courteous and hard working. The underneath the house install was especially difficult with a tight crawl space in a less than hospital environment. These guys were not a show up at 10 leave at 3 pm crew.......they worked long hours both days to ensure they met the promised schedule.They kept me informed any issues throughout the installation process so there were no surprises. At the end of two days we had two beautifully installed systems that now cool our 4000 sq ft house in a matter of an hour instead of the 4 or 5 the old system required. I feel that the pricing they gave me was very fair and at the end of the job I felt like I got more value than what I paid. I would certainly use them again in the future."

"Will came on time and came in and told me had did several of the homes in my area, so he wouldn't need to do a load-test for our home. I felt a little nervous about not doing a load test because I know too small or too big of a a/c unit both have its problem, but I took it on good faith that he knew what he was doing. He asked me what I wanted, I told him just basic a/c unit., as I wouldn't be using it much (just for very hot days). He provided me with 2 options - a complete new HVAC system ($9,545.31) or just an A/C Unit & Compressor ($7,652.31). He also explained that Carini was extremely busy and that they were 1 month out on scheduling any installations."

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.

"Vlad provided excellent service and answered all my questions clearly (and I asked a lot!). We have an older furnace, and he tweaked the settings to get it working as well as possible. Very happy with the results!"

"Excellent work. Far surpassed expectations. Highly competent & professional from initial analysis of multiple problems and engineered a solution followed by a fast, efficient tear-out and installation by terrific crew to final clean-up. Excellent value. Job was professionally done the way the original installing HVAC contractor should have done years ago. Highly recommended."

Heating and Air Conditioning FAQs, answered by experts

Air conditioners can stop working in the middle of the night for many reasons. Your local power grid might shut down late at night. Power surges can also trip your breakers if too much power is being used in the area at the time. If your AC is connected to a digital thermostat, it gets naturally cooler at night, so the outdoor temperature might dip below the automated setting to turn the cooling system off.

A power outage can damage your air conditioner, just like a power surge can damage any electrical device or appliance. In most cases, your circuit breaker or built-in surge protection on your AC unit protects your AC and just needs a reset. But in other cases, it might be that your AC compressor or capacitor was blown during the power surge. You’ll need to have an HVAC professional repair or replace any AC parts. 

A new HVAC system combines components to control indoor temperature and air quality. Features include a furnace or heat pump and an air conditioner or evaporator coil, depending on the climate requirements. It also involves a network of ductwork for air distribution, a thermostat for temperature regulation, and electrical connections. Air purifiers or humidifiers can be integrated to improve indoor air quality.

NATE (North American Technician Excellence) certification is not legally required for HVAC technicians in most areas, but hiring a professional with this certification is highly recommended. NATE-certified technicians demonstrated their expertise and proficiency in different types of HVAC systems, offering assurance of quality service. It's a voluntary certification, yet it indicates a commitment to professionalism and ongoing training. Choosing a NATE-certified technician often means you're working with someone who is up-to-date on industry standards and best practices, which can lead to better service, energy efficiency, and long-term cost savings.

During the summer, it’s best to set your AC to 78 degrees when you’re home and awake, according to the Department of Energy (DOE). For better energy efficiency, raise the temperature slightly to 85 degrees while you’re out of the house. The National Sleep Foundation advises lowering your thermostat to between 60 and 67 degrees when you’re asleep.
