"Very well. My ownly concern is the cost. Seemed to be to be a little high for the job that was done. Of course I am not that familiar concerning today's prices. Thans for the service."

Replacing an outdoor air conditioner with a high efficiency, consumer reported top rated American Standard unit.  Level, wired properly, and completed beyond code and required standards.  Thank goodness for a team that cares and loves what they do AND our customers.
Great technicians who have amazing skill and are just good humans too.

"I hired Alliance to complete several jobs in my newly purchased home including: 1. bringing bathroom and kitchen plumbing up to code, 2. installing a garbage disposal and faucet, 3. installing a new toilet and fixing plumbing to toilet, and 4. multiple pinpoint leaks and pipe corrosion in the basement plumbing. From the start, it was such an easy and stress-free process. Communication was constant through email and text about the service dates and ETA of the team members, which was fantastic as I was traveling back and forth between my current and new home. The estimator (Mike) was at my home the day after I made the initial call and walked through everything with me in a friendly, well-informed, and pressure-less manner. He never tried to upsell me and, in fact, helped me prioritize the most important items to address. The plumbing technician (Andrew) was at my house five days later with all of the required materials and worked for 8 hours on the various items. He even found and fixed another broken component while working which probably saved me additional stress and money! At the end of the service, he walked through all of the fixes, went over the warranties associated with them, and ensured my satisfaction before processing payment. He was so impressive that another contractor working on the painting in my home asked him for Alliance's business card. I would hire Alliance again for any plumbing need and would recommend them without hesitation to friends, family, strangers, or anyone else with plumbing needs!"

"I needed a repair to my oil furnace; I received a quick call from the office and set up an appointment. Bill and Tito arrived promptly and took time to explain what the issue was and made the repair quickly. Fair price too! Later in the evening I received a call from the office, checking in to see if all went well- great customer service! From start to finish, they were professional: I highly recommend Pro Energy Solutions."

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