"They were very responsive and scheduled an appointment right away. The service technician arrived when they said he would. He put on shoe covers to keep my floor clean and did an excellent job repairing our furnace in a timely manner. I would call them again!"

"I had a very dirty a/c unit, and didn't want to clean it myself. Was afraid of damaging the fins, plus it hadn't been serviced for years prior to us purchasing this duplex. The gentleman arrived exactly on time. He cleaned it very well, then check the furnace filter which was also very dirty, replaced it. Also checked the R22 level, had to put a lb in and then checked the output of cold air. It was perfect. Told me the approximate age of unit and what to look for in the future. Highly recommended."

"Shane was able to schedule a prompt appointment. He arrived on time and performed a thorough diagnostic on the furnace. He identified an issue I was unaware of and corrected the problem with the air conditioner using parts that were still under warranty. I will gladly use his services again."

"I cannot say enough about our technician, Jordan, or the service of In Phase. We put our request into Angi and probably 1 minute later In Phase called. We have been wanting to upgrade our house to Ecobee since we purchased it two years ago. We thought we could do it ourselves, but our home had 3 zones, a two-wire boiler, and a newly added Central Air system. I had tried to hire other companies to do the job in the past, but very few companies were familiar with Ecobees. When In Phase called they were confident in the Ecobee system and were able to get us in the next day. Jordan showed up on time and was very personable and knowledgeable about the system. He had everything up and running in about 2.5 hours. This easily saved my husband and I a weekend of working on this, not to mention the fact that I didn't have to hear any cursing. (LOL!) BTW...we had already purchased everything, Jordan installed it and got it all set up for us. Many thanks!"

"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."

"There is no air conditioning on the first floor of the non-profit house for which I am Property Director.  With the donation of and installation of a window AC unit, it was suggested that a ceiling fan in the living room (where the AC unit was installed) would help circulate the cool air.  I had worked w/Horizon Electric previously for electrical repairs, but not for an installation requiring new wiring, etc.  The owner, Lee, met me at the house within a few days and almost immediately found a way to wire in a new ceiling fan in the living room.  With further discussion we decided a ceiling fan w/lights would also be worthwhile in the dining area.  In that case he had to extend wiring to this adjacent room and, again, came up with a solution.   He quoted me a price for the installation of the living room fan only and another for the installation of both fans.  
With Board of Directors approval I was able to get back to him within the week and the following week both fans were installed. Even though Lee had told me that his workload was out 2-3 weeks, he understood the importance of getting these fans installed 
and that was done in record time.  The House Manager reported to me that the workman finished the installation of the fans we provided in one day, as promised, and, even with the house residents present (including young children), left nothing lying about that could be hazardous to anyone, was efficient and cleaned up the work area thoroughly after he was done.
We were billed the amount quoted.
I would definitely use this company again and highly recommend it.

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