"Dwight Miller (DMiller Mechanical) came to our house to give us a quote on replacing our 20 year old geothermal furnace that we’ve been pouring money into for repairs and also to replace our 20 year old hot water tank. He was 1 of 3 contractors invited to price his services He did a detailed examination of our current systems and explained our options in an logical, no pressure manner. He also provided a firm quote in writing for the cost to do the job. We thanked him for his time while we waited on the other 2 contractors to give us their quotes over the next few days Price is not always the final factor when spending the hard earned money we were about to spend One contractor was less expensive and one was way more expensive. Dwight’s quote was somewhere in the middle We chose Dwight and his team for a variety of reasons: He could do the job very quickly verses waiting 6-8 weeks He was local. You want someone that can meet your needs if problems arise. His is a family owned business. His income and livelihood depends on his reputation (high marks on HomeAdvisor) The personal connection we felt in our spirit with Dwight. He is a like minded, kind hearted Christian business man It turns out that Dwight was the correct person to deal with. Dwight and his adult sons(experienced professionals themselves) showed up each day when they said they would They went out of their way to protect the interior of our home during the tear out of my old systems and the installation of the new units This was a large, labor intensive, skilled job. They took the upmost care to make sure the installation was perfect. Duct work was hand crafted to attach to my existing ducts After the multi-day job was completed they hauled away the old units. They throughly cleaned up the work area. You couldn’t even tell someone had just worked there when they had finished Dwight then took the time to fully explain to my wife and I how the controls worked so that we understood them. This long winded review is for the purpose of stating: If you want an honest, hard working Christian family business that is very professional and makes sure you are happy with the results, then DMiller Mechanical is the company you SHOULD hire to do your heating and cooling work. He is the real deal and I highly recommend that you hire him with NO reservations You won’t regret it"

"Computer did the "gotta send info to Microsoft" but when tried to reboot it ran through automatic repair without success. I did all the alternative without any success. He came and picked up the hard drive on Tuesday and returned it on Saturday. Fortunately he was able to "restore" without any data loss. Very happy with outcome."

"Everything Mike said he would do, he did. The old caulking needed removed first, and that was a lot of prep work, especially on the second story windows. We went a little over the project estimate, but that was due to the amount of prep time it took. No mess was left after the work. Communication was excellent all the way. Highly recommend this handyman to anyone in need of having their windows caulked and exterior foundation painted."

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