"My wife and I were throughly impressed with the professionalism of the company and their installation crew. They were meticulous in their work practices and went out of their way to keep us informed of the status of our air conditioning project from planning to completion. It was truly a pleasure dealing with such an honest and ethical HVAC contractor. Michael Santana, along with his talented team of Enrique and Raul more than exceeded our expectations with their outstanding work and customer service. We solicited quotes from numerous contractors and Aire Care Heating and Air Conditioning hands down provided the best cost and installation proposal. If you are looking to replace your HVAC system, I highly recommend that you contact them."

"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.

"Josh and his helper showed up on time, were professional, efficient, and knowledgeable and fair. They fixed my broken heat pump for $80.00 when another company had told me that it would be at least $500 to simply locate the problem. I would highly recommend All Day Heating and Air for a/c fixed right."

"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."

"Randy the sales rep set up the order for a replacement HVAC system, managed to find inventory in these post-pandemic days of shortages, Chuy and his workmate Eddie did a great job of installing the inside and outside parts of the system while adapting to the unique issues in our condo and then taught us how to use it. The office staff supported them and it all went in place very nicely. Pricing was not cheap but it was competitive. I would not hesitate to use Baker for my future needs. Oh, and the workers were very respectful of our home and wore boot covers and placed covers over things in a closet that was used for attic access."



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.
