Is Your Ductless Mini Split Heating & Air Conditioner Acting Up?

Catching early warning signs keeps your system from throwing a total wrench in your plans. Nip these common mini-split problems in the bud to protect your compressor and avoid big replacement bills. At Arnica Heating And Air Conditioning, we offer comprehensive ductless heating and air conditioning repair and maintenance services to keep your system up and running throughout the year. 

Lukewarm Airflow Issues

If your unit is just blowing warm air, it usually points to a clogged path or low refrigerant. Our precise diagnostics pinpoint the trouble spot to bring back that refreshing, icy breeze.

System Won't Kick On

Bad control boards or electrical wiring glitches can leave your system completely dead. We trace the power paths from top to bottom to locate the exact breaker or part causing the hitch.

Temperamental Room Zoning

When one room stays stifling while another is freezing cold, your communication lines are likely out of whack. We recalibrate the system to get your indoor temperatures leveled out across the board.

Funk or Burning Smells

Musty smells mean mold is hiding out in the blower, while burning odors mean electrical trouble. We deep-clean internal parts and swap out bad wiring so you can breathe easy again.

Water Pools or Refrigerant Leak

Blocked drain lines will cause water to back up and make a mess of your drywall. Our team clears blockages fast and patches up tricky leaks to keep everything safe and dry.

Racket or Strange Noises

Loose fan blades or worn bearings will start making a loud racket during the day. We tighten up internal mounts and replace old parts to make your system run whisper-quiet again.

Weak or Choked Airflow

Clogged filters and gunked-up blower wheels really choke your system's output. We clear out the built-up dirt, giving your airflow a serious shot in the arm and easing strain on the motor.

Constant Short Cycling

Starting and stopping constantly runs your compressor ragged and drives your electric bill through the roof. We fix bad thermostats or misplaced sensors to get your cooling cycles back on track.

Utility Bills Skyrocketing

When dirty coils force your system to work overtime, your energy bills take a major hit. Our thorough ductless air conditioner heating and air conditioning repair service clears away the strain, dropping your power usage back down to earth.

Remote Control or Thermostat Glitches

Broken remote eyes or dead wall controllers lock you out of managing your comfort. We swap out bad sensors and rewire connections to get you back in the driver's seat.

Rebate Support

We help you navigate savings, including the ARNICA rebate up to $3,000 and available ConEdison rebates to maximize your investment.

Our family has been using Arnica for heating and air-conditioning for years. I felt compelled to leave this review because I want to give them the credit they deserve! Especially after this last service during 95° weather my father’s old air-conditioning system broke down and they did everything they could to quickly get the part needed and fix it. The office workers are very responsive and supportive. And the tech was knowledgeable, confident, and did a clean job. Thank you to everyone there at Arnica! We appreciate your help!!

The Arnica office team was clear, courteous and responsive when it came to scheduling an assessment visit. The technician arrived on time and was very efficient in his work. They were able to do the repair work that same day within the original visit window, and now I'm back in business with conditioned air flowing again.

Arnica HVAC handled my install exactly how it should be done—professional, clean, and efficient. They set up a system with three split units running off one condenser, and everything was executed flawlessly. The crew showed up on time, worked fast without rushing, and kept the space clean the entire time. You can tell they know what they’re doing—no shortcuts, no sloppiness. The system looks clean, runs properly, and the quality of the work is obvious. Straightforward, high-level job from start to finish.

I was shopping around for a brand new HVAC system installation during renovation of my place. I found a few companies and compared their services, prices and availability. Arnica looked pretty nice so we picked them. So far the installation service went pretty well. Everything got installed on time and I was always notified on their schedule which helped a lot to plan accordingly. Their office manager Rosette kept communication clear and explained me various things I had to go through to make sure everything is smooth and as planned. She helped a lot and made the whole process smooth and clear. Dean helped to settle various technical aspects before I signed and during the whole process. I will definitely recommend their service to others. Thank you!

Outstanding from start to finish. I did a whole home Mitsubishi A/C with HyperHeat installation, 11 indoor units with 3 outdoor units in total. Dean came out and did the consultation, then provided a proposal by email and once agreed upon everything was scheduled and installed expeditiously. Any questions or concerns I had along the way were answered quickly. It’s tough at times to find a good company with good people and workers but Arnica has it all. And if you’re considering a Mitsubishi system they are a Diamond installer which does matter. Dean, Rosette, Marco , Adam and everyone both in the office and on the installation crew were a pleasure to work with.

We decided to switch from oil heat to heat pumps before the federal tax incentives were phased out and after much research chose Arnica to guide us and install the system. Rosette, the office manager, was wonderful at every step of the way, and the technicians, Marco and Mario, and Victor and Cesar, were absolute pros, not only completely knowledgable about the technology and excellent at what they do, but kind and courteous as well. Fair price, excellent customer service, and skilled technicians who did a fantastic job. If you're considering a I highly recommend Arnica.
