"Noticed one of my bedrooms wasn’t getting the same air pressure as the others. I called the guys at sky clean air and was scheduled for the following day for a free quote. Nadav and Erick were on time and quickly got to work, because the age of the house the duct connected to the spare room had become brittle and damaged. I was given a quote for the single duct and replacing the attic I was never pushed into making a decision. Ended up going with the single duct and work was done same day with before and after pictures. My experience with Sky Clean Air is the type of business you want to deal with never felt like I was being played. Definitely recommend"

"I had three top rated heating and air conditioning contractors bid on the installation of air conditioning to my existing heating system. I wanted a quite and efficient two stage ac unit that would work with the variable speed blower in the heating system. Carini was the only contractor that based their bid on a heat load calculation rather than some rules of thumb that tend to oversize the ac system. Their analysis indicated that I needed a three ton unit. The other contractors said that I needed a four or five ton unit, but the blower in the existing furnace and the ductwork would only support a three ton unit. One of the other contractors no bid the job after I said I was not going to install a new furnace and ductwork. The other bidder said they would install a three ton unit but would not guarantee satisfaction. At this point I didn't know who was right. I then contacted my neighbors with AC and the same model home as I have. They all said that they had 3 ton units and we very satisfied. Based on their results I contracted with Carini Heating and Air Conditioning. The installation was planned for one day but actually took 2 and a half days. The installation itself was done in a day and a half but complications with integrating a 2 stage AC unit with a variable speed furnace from another manufacturer required another day to resolve. To his credit, when Jason Baer the project manager found out about the problems integrating the Bryant AC unit with a York furnace he assigned their lead service technician, Anthony DeCarolis to integrate the two units. After several hour of studying both the ac manual and the furnace manual Anthony was able to achieve the expected performance by a combination of DIP switch and jumper setting in both units and the installation of a two stage thermostat. Although I took a few days longer than planned, I am very happy with the overall performance of Carini and my new air conditioner."

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.

"Vadim, the owner of the company, showed up right on time, explained what was wrong, exactly what he could do to solve the problem with our furnace and what it would cost. He took care of the situation over the course of the next 45 minutes and the furnace is running again as it should. We would highly recommend Cool Air to anyone looking for repairs or advice as to what they their options are for taking care of problems with air conditioning or furnace concerns. Vadim was professional, courteous and efficient."

"Edgar and Omar came early and they were very nice. Edgar asked good question on how I would like different option for my back splash placement. They were able to complete the job in one afternoon. We are placing our house up for sell so Edgar squeezed us in even though he was working on other jobs. We had a new ceiling fan that needed to be installed and they didn't hesitate when we asked if they could install it. We wish we had known about Edgar and Omar sooner because We wouldn't have had to endure the other idiots. We highly recommend this team for any home repairs!!!!!!!! They cleaned up after themselves and they are very professional."

FAQs for air conditioning projects in Descanso, CA

Most professional HVAC technicians require two to three hours to complete an expansion valve replacement. The timeframe depends on your unit's accessibility and whether additional repairs are needed. The process involves recovering refrigerant, removing the old valve, installing the new component, and recharging the system. Scheduling during less busy seasons may result in more convenient appointment times.

Operating your air conditioner with a malfunctioning expansion valve isn't advisable. Continuing to run the system could potentially damage other components, particularly your compressor, which is significantly more expensive to replace. If you notice performance issues like inconsistent cooling or unusual noises, it's best to have your system inspected before continuing regular use.

Expansion valves don't have a standard replacement schedule, as their longevity depends on system usage, maintenance frequency, and environmental factors. Regular professional maintenance helps identify potential valve issues before they cause system failure. Having your HVAC system serviced annually allows technicians to monitor component condition and recommend preventative replacements when necessary.

Refrigerant leaks require prompt professional attention. If your expansion valve is leaking, you'll likely notice reduced cooling performance and possibly hear hissing sounds near the unit. Addressing leaks quickly prevents further system inefficiency and avoids the environmental impact of released refrigerant. Your HVAC technician will need to repair the leak and recharge the system with the proper refrigerant type and amount.

Because many AC issues present similar symptoms, professional diagnosis is recommended. Problems like inadequate cooling, inconsistent temperatures, or strange noises could indicate expansion valve issues, but might also stem from refrigerant leaks, electrical problems, or airflow restrictions. A qualified HVAC technician has the tools and expertise to accurately identify the root cause and recommend appropriate repairs.
