We offer professional technicians, same-day installations and 24-hour emergency service. We believe we are the right choice for any of your HVAC, Plumbing, or Electrical needs. Call today to schedule your next appointment!

"Had an old fixture above kitchen sink go kaput (fluorescent starter disintegrated), so Cardinal came out and offered LED alternatives (two provided, brought on-hand from supply warehouse). Also fixed a switched outlet that had shorted out. Great work done, nice alternatives for the LED light, and switched outlet was wired to be always-on for one socket and switched for the other -- better than it was before at no additional cost. Later I called to ask the exact serial and model number of the LED light because the papers left did not state it. Not only did I get an email a couple hours later with the model/serial, the tech included the detailed documentation for the fixture so if anything goes wrong I can likely fix it myself next time. The tech who did the work also applied a 10% off discount card for me with no extra hassle, saving me close to $100 on the work."

"I had an incredibly disappointing experience with Adams Electric, and I feel compelled to share my story so others can be aware. Over the past few months, Adams Electric has failed to complete electrical work that was promised, left my home in disarray, and charged outrageous fees for unresolved issues—including a $540 bill for a toilet that still doesn’t work after three visits. I personally went to their office in tears, asking for help, and my concerns were completely ignored. I have sent multiple requests for resolution, yet I have received no accountability or action from their leadership. As a company that claims to be faith-based and community-driven, their lack of integrity is deeply disappointing. I will be pursuing every possible avenue to get the resolution I deserve, including reporting them to consumer protection agencies and escalating this issue publicly if needed. I sincerely hope Adams Electric chooses to do the right thing and take responsibility for their actions."

FAQs for central a/c service or repair projects in Beaver Dam, WI

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.
