"They installed our unit in March 2015, and the unit induced motor was found to be defective in Nov 2015. They not only charged us for the service call but also charged us for the part which was under warranty. It was very unprofessional. The same part after less than 5 years failed again, and they took no responsibility for their workmanship. Customer service Person does not deal with the customer on the request. This time again they were charging us for the defective part and exorbitantly for the service call under the pretext that we did not sign a maintenance contract with them. So we did not finally go with them but went with another vendor who is far better and professional."

"Changing my 5 star review to 2 stars. We have had a HE Boiler as well as a AC/Heat Pump installed by them. Unfortunately we needed service today. I was willing to pay for Emergency service. They said they couldn't make it out for 14 days, because we did not have a service contract. Spent about $25k for the installations. Which apparently means nothing to them What makes matters worse, the Emergency Service we paid through another HVAC provider was only necessary because of an issue they created during the installation. During the installation Speer Air originally ran the line for the residual pump over the copper hot water line. Which over time burned through the residual line, and then cause a hole and leak on the copper pipe."

FAQs for central a/c service or repair projects in Sparta, 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.
