"Sam called immediately and AJ was here earlier than the scheduled time. They replaced a fuse for the air handler and solved a two year mystery of why the AC wasnâ t working. They also charged and cleaned two condensers right before the summer heat set in. Will be calling them for our other central hvac system very soon!"

"My wife and I moved into our home about two years ago and inherited a very old hot water heater (12+ years old) and boiler (25+ years old).  They were working fine, but they were on their last legs and could go at any time.  More importantly, 2 of the 3 upstairs bedrooms were always cold, little heat reached those rooms through the baseboard radiators, and we wanted to see what could be done to get it fixed.  This was very important to us since one of those rooms was going to be used as a nursery the following month.
I spoke to Dave on the phone who set up an appointment for the next day to investigate.  He assessed the water heater and boiler, letting me know that they were currently working fine, explained how it worked, and that the boiler was missing a safety feature that is now required in newly installed boilers (I think it was something like an expansion tank?).  He explained it very well, I could tell he knew what he was talking about.  To solve the cold bedrooms riddle, Dave walked around the basement, looking at the exposed pipes and where they were headed.  Then he went to the rooms on the first floor, noting the locations of the radiators.  Finally he went to the 2nd floor to see where the rooms were and the radiator locations.  He found that the rooms were connected just fine, but that they were on the end of a long loop of rooms being heated.  The 2 bedrooms were located on the same zone as the entire first floor, and as a result, were not being heated effectively.  In addition, the thermostat was on the first floor, meaning once the desired temperature was reached on the first floor, the system shut down, leaving the 2nd floor in the cold.  To fix, he recommended adding a third zone by reconnecting the 2nd floor pipes in the basement directly to the boiler and connecting a new 2nd floor thermostat to the boiler so that it would continue working until the 2nd floor rooms were warm.
It should be pointed out that the original intent of my service call was not to get a new boiler, but to fix the heating problem on my 2nd floor.  The 3rd zone solution complicated things with my older boiler, which would have had to be retrofitted with a bigger opening to accommodate the 3 zones.  Dave advised that rather than spending money on those enhancements, which would go to waste if and when my boiler dies, that I may have wanted to consider getting a new boiler.
My wife and I agreed to the work and we scheduled an appointment a few weeks later to get the work completed.  On Day 1, they replaced the water heater and did some work on the 2nd floor piping in the basement.  On Day 2, they replaced the boiler and connected all 3 zones, including the new 3rd zone.  The crew was excellent, putting down drop cloths around the house where they were walking around to drain the radiators and cleaning up behind them.  When the work was completed, Dave walked me around and showed me what they did and gave me a tutorial of how the new thermostat worked.  Everything worked perfectly and the upstairs bedrooms are now nice and warm!
Dave came back a few days later and dropped off the invoice, warranty, and completed rebate details (all I had to do was fill in my address and mail it out).  He also asked how things were going and answered some questions for me, including how I could adjust temperatures in the room using the radiators.
All in all, I think I got my money's worth and would recommend Dawson to my friends and family for any heating work.

"Rays HVAC tech came in and evaluated the problem with the A/C (early Sept. 2020). The coil was freezing up and dripping water. Another company wanted to replace the coil for over $3,000. Rays said it just needed free-on. Topped it off for $200 and the system ran fine after the service. would highly recommend it. Used Rays HVAC for a heating issue March 2021. Ray was quickly reachable, great communication, came the next afternoon. Great job on the repair and for a very good price."

"I had a very old Oil Burner that broke beyond repair. I contacted SS work services through Angiâ s list. Rob Called me right away. He came, inspected ordered the parts needed. Five days later three of his workers spent up to 20 hours in 3 days, removing my old burner and constructing a new one. They explained the steps I had to take in maintaining it. They were very efficient and I tipped them also. Today I had my inspection from the town and Both inspectors said when they saw my new furnace said that they did a great job. SOS work services were affordable, on top of everything, And overall nice quality guys. I have already handed out their business cards to friends and family. I highly recommend SOS work services."

"I recently hired Kyle to service my central air conditioner. What a find!!!! I will absolutely hire him again. He is bright, personable and explains every step of his process. You can tell he is passionate about HVAC, and enjoys his work. He was able to quickly evaluate my system and get it back up and running. My system is old and really needs to be replace but Kyle was able to keep in running for another year... Highly recommend this company"

FAQs for central a/c service or repair projects in East Hanover, NJ

Coils work to absorb heat into the refrigerant that flows through them, moving heat from one location to another. For air conditioning, the evaporator coil inside the air handler in your home absorbs heat. It then transfers the heat outside to the condenser coil, where it releases it. The opposite process happens for heat pumps. When the coils get dusty and dirty, it reduces how well these components work.

Skip regular cleanings, and dirt, debris, and mineral deposits will blanket your evaporator and condenser coils. When that happens, the coils can’t shed heat efficiently, so the system works harder and your energy bill climbs. Over time, overheating strains the compressor and can trigger a full breakdown—an avoidable repair that often costs far more than a simple annual cleaning.

AC coil cleaning is an investment that pays for itself in the benefits it provides. Dust‑caked coils force your AC to run longer, so you spend more on electricity and rack up extra wear. A quick professional cleaning restores efficiency, trims monthly bills, and eases strain on expensive parts. Over the long haul, that small yearly fee delays pricy repairs and stretches the unit’s lifespan, making coil cleaning one of the smartest HVAC tune‑ups you can schedule.

Watch for higher electric bills, rooms that stay warm no matter how low you set the thermostat, or an AC system that runs nonstop. Extra humidity and frost on the coils are also red flags. Catching these clues early lets you schedule a quick cleaning before the system overworks itself and triggers an expensive breakdown.

Your AC cleaning technician starts by shutting off the power to the unit and removing the faceplate. Compressed air and a vacuum hose blast away loose debris, followed by a coil-safe, no-rinse cleaner that dissolves stubborn grime. After the solution has soaked in, the professional wipes the fins, reassembles the housing, and restores power, leaving the system ready to cool at peak efficiency.
