"A three day project to replace my very old furnace and install central air throughout the house. They had to run 3 lines of new duct work plus one cold air return to the new addition. Put in a 95% efficient furnace that now keeps my entire home at exactly the same temp. Their workers were always on time and provided service above and beyond. Wish I could get this kind of quality work in everything. Because of the cold weather they will have to come back out to finish up the AC."

"We recently moved to Huron and the house we purchased has a gas water heating system which we have never had any dealings with.  When it seemed to take a very long time to heat the house we were concerned.  I called Gilbert Heating and Air Conditioning because there were tags on the furnace showing that they had previously serviced it.  Even though I had never used this company before, they scheduled me for 8:00 am the next morning.  This is a much better turnaround time than I have ever received before from any service company.  A technician named Tanner showed up on time and was very helpful.  Although there turned out not to be anything wrong with the furnace, Tanner gave us some tips and explained the heating method to us.

"They came in to inspect our firplace and chimney the summer of 2012, and they were honest with us.  The person who came out let us know that our system was in great condition, and did not need any service. He could of easliy over sold us on unnecessary products and services. We appreciate his honesty.

FAQs for central a/c service or repair projects in Norwalk, OH

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.
