"I was very happy with my experience using this company. In the middle of a heat wave, right before the July 4th holiday, my AC stopped working. The man who installed it and had been servicing it was too busy to come for a week. I called MSD and was given an appointment for 8 AM the next morning. They were prompt and courteous, fixed my problem, and were reasonably priced. I will be calling them in the future."

"Excellent! The team worked diligently for 5 days to install a central air system in our old house with Plaster Walls. It was NOT easy, yet they did a fantastic job. They were able to add all ducts to the first floor with out any "chases" or enclosures requiring to be build. And almost none of our first floor lines up with our second floor closets, but they figured it out. Great time and fantastic service. Make sure you get Brandon and Sean. The work their butts off, and ensure your house stays clean (they cleaned up everything after every day - not an easy feat). Cannot say how happy am I with their work!"

"I had my HVAC replaced in my condo during the summer of 2018. I had just moved and had painters working when it malfunctioned. There turned out to be a leak and I decided to purchase a new system after hearing about previous problems with the unit. I had used Valairco for annual checkups and was happy with the company. I ordered the new system requesting it be done as soon as possible because of the situation. They immediately ordered the new system and installed it as soon as it was shipped to them. Lou did a great job and I’m happy with my purchase and guarantee."

"

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 Raritan, 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.
