"Our 35+ year old furnace went out last November. Artur came and evaluated our systems. We ended up installing 2 new HVAC systems. He was very thorough and explained everything, answering all our questions. The installation was on time and the crew was very competent but also neat, thoughtful and polite. The best part: our system since we bought our house was never optimal despite lots of companies working on it over the years but now for the first time, I can say WE ARE TRULY COMFORTABLE WITH THE TEMPERATURE IN OUR HOME. When the A/C is on, it is perfect and when the heat is on we are warm. I strongly recommend this company. You will be satisfied!"

"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."

"I hired RJK Mechanical to clean my Air Ducts and Dryer Hose. Chad and Jamey did a great job! They were very patient and informative while I asked them many questions on how the Duct system works and how to avoid re-contamination of pet related allergens in my home while other companies clean my home for a move-in. I would also like to thank Will for be very responsive, informative and helpful. This is the most customer friendly company that I have ever dealt with. Thank you for having the best staff. I would highly recommend this company."

FAQs for air conditioning projects in Milltown, 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.
