"They took a look at the air conditioner which was not cooling my house. They refilled with freon and then recommended some changes. Price was good. The worker they sent was definitely experienced, he went right out to identify the problem. Pretty personable. He didn't mind me looking at what was going on."

"Just had AAC install a new central air conditioning system. Adam and John were both friendly and courteous. Very knowledgeable about what they were doing. Were respectful of our property and kept a clean work area. Excellent value for the money. They worked thru some rough conditions, bearing up with 150+ degrees in the attic. Would definitely recommend them and use their services again when needed."

"My AC went down during the hottest part of the summer and I was desperate for a replacement. After several quotes, I was lead to Oscar, Owner of Whitestone HVAC, and I couldn't be more happy with the results. He replaced my central air and converted my baseboard heating to central heat with a BETTER product for significantly less than the competition. He also finished in record time working in temps of over 100 degrees in the attic. It has been more than a month and the system is operating to perfection, silently cooling and saving me money on my energy bill. If you're looking for a Certified, Mater Technician, who will work efficiently to give you the best results for the best price, Whitestonehvac.com is your solution."

"Raynor's employees were very professional. They were very conscious of cleanliness. They wore booties whenever inside

my house and cleaned up after they were done. The only evidence of them being here was the new unit. The installers instructed me and gave me tips on running the new heat pump. They also answered any questions I had while they were doing the installation. They were very knowledgeable about heat pumps. Matt the sales rep was very accommodating in helping me meet my

budget with the proper equipment. I am extremely happy about the new unit as it works just like they said. It runs smoothly

and quietly. The owner of Raynors also stopped in to make sure that everything was done properly and make sure I was happy.

They also did a good job of following up with the NJ rebate paperwork. I would recommend them to everybody without hesitation.

"

we had a leak problem and the tech came and looked over our equipment, fixed the problem and left. It cost us nothing and we have had their home heating service contracts for over 20 years.  They have NEVER ONCE not shown up or not helped and in the two furnace emergencies we had--they were here with in 1hr. 

We are very happy.

FAQs for air conditioning projects in Princeton Junction, NJ

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.
