"Rey was very thorough. He explained what was wrong with my system and why the part he replaced needed to be. He didn't try to sell me anything that I didn't want or need and I didn't feel like I was a dollar sign."

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

"Very well...the men were very efficient and courteous and hard working. They did a good job of communicating with us and were very thorough in repairing the decking and fascia where needed, and did a good job of cleaning up the work site. The roof looks very good.

"CHW was very responsive to our urgent need! We filed a claim the evening prior when we notices our A/C was blowing warm air into the rooms. Then by 8AM the next day, we had a call from the service technician saying he was on his way to address the issue! CHW worked with the technician to find out the compressor was the culprit and approved it's repair! Great customer service for a family in need during the hot south central Texas summer!"

"Worth the money, since the provider found things that would have cost more to fix eventually.  Gave me a few tips to maximize furnace performance.   I definitely would recommend this service and this technician (Jeff).  Very helpful and professional.

FAQs for central a/c service or repair projects in Herndon, PA

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.
