"Alpine installed my Trane heating and air conditioning system 18 years ago. At that time, I decided to purchase a service contract that would allow me to receive 2x a year cleaning and inspection. It was the best investment I could have made! Today their technician Troy came to conduct the preseason service on my air conditioner. My appointment was for 10am and Troy arrived promptly at 10am! During the course of the inspection, Troy discovered that the dual run capacitor was leaking oil. He showed me the part and suggested that it could be a problem down the road. Since the system is 18 years old, I wasn't surprised that there might be a worn part that would need to be replaced. Luckily, he had the part on hand and was able to do the repair right away. Because I had the service contract, I received a discount on the parts and labor which was greatly appreciated. I'm so glad that I called Alpine all those years ago. I highly recommend them for your heating and cooling needs!"

"Angie’s list has Valairco listed as #1 in my area for home HVAC and my 30 year old York R-22 central ac has been leaking for a while. I had Valairco give me a quote to replace the air handler, and the outside compressor, condenser unit with a new unit that uses the new R410a Freon. The estimate seemed a bit high but I was surprised that I wasn’t offered any refund for whatever R-22 they reclaimed from my old system. I started entertaining other quotes when I received an e-mail from Valairco. I responded and explained my disappointment for not being offered something for the reclaimed R-22. I got a phone call shortly after that and was told if I could have it installed the following Friday they would reduce the price by $250.00. I agreed to have them install it. The day prior to installation a plumbing supply truck arrives in front of my home. The driver unloads all the parts for the job in the pouring down rain. I thought it was odd not to alert me since some items would not be helped by a good soaking. I put those inside. It turned out that the plumbing supply delivered a day earlier than instructed. The installers arrived on 7:00 am on Friday. They started disassembling the old system. Two more men from Valairco arrived. It was decided that it was easiest to remove the attic ladder to make room to lift the new air handler into place. As soon as it was up the two additional guys left and for the next 9 1/2 hours the two installers worked in the attic and outdoors to finish the installation. Overall I am pleased with the competence of the installers. I am also pleased with how well they cleaned everything up after they were finished. The new raceway looks better and the thermostat has Automatic Changeover and Adaptive Intelligent Recovery which are nice features. They also do the first year preventative maintenance at no additional cost. The price was exactly what they had quoted. No taxes or hidden costs were added. I was not pleased with a few things. Valairco is poor at communicating. I was told that it would be a two day install at time of quote but they completed it in one marathon day. The installers changed the orientation of the air handler to make it easier to service. It isn’t an issue but it would have been nice to be asked. What if I wanted it that way for storage? My attic ladder was reinstalled with 5 bolts when it is drilled for 6. Maybe one was missing before they started or maybe they lost one. Either way they left it with 5 and did not tell me. The installers relocated the hole where the lines exit the attic through the soffit and patched the unused area with a piece of galvanized steel because they didn’t have any white aluminum on their truck. Not only did it look bad but when you screw unlike metals together you start a corrosive process. I’ was not looking forward to seeing rust stains running down the side of my house. The attic routing of the copper and electric lines are hanging in midair and looks sloppy and amateur. Only one clamp holds it to a joist and it only has one screw. The rest of it hangs 6” below the joists for no reason and creates an unnecessary obstacle. Valairco did not know that I was displeased right away. After reading my initial review here, Richard Valenti, Valairco founder, personally calls me. I did not realize that they normally do their follow up a month after completion, in order to give the customer time to use the unit under a number of weather conditions. He sent Kevin back with the installers to make me happy. They fixed the soffit with a new piece of aluminum. They put anew bolt in the attic ladder. They put a strap hanger on the lines. Kevin offered to come back after cooling season to replace the lines if I am still not happy with them. I asked him if he would have done the installation the way his installers did and if he found the installation satisfactory. Kevin did not answer. It was obvious they returned to satisfy me whether my expectations were valid or not. I am pleased that they returned and I can say that customer satisfaction is important to them."

"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 were without heat for six days and had no success from other companies that were recommended by friends/family; I went through Home Advisors and had an appointment with Fontaine Repair HVAC with in the hour. Tony was very professional, curtious and thorough with the work and explanation of what needed to be done. He fixed the problem in a timely manner and gave instructions on how to prevent the problem from occuring again. I would definitely use Fontaine Repair HVAC again and would highly recommend them to anyone who is looking for a knowledgable, honest company."

FAQs for air conditioning projects in Hillsborough, 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.
