Frequently Asked Questions
- <p>Yes. Modern ductless mini-splits are designed to operate efficiently in cold climates, with many models heating effectively at temperatures well below zero. Systems from manufacturers like Mitsubishi are rated to operate down to -13 degrees Fahrenheit, making them well-suited for Central Ohio winters.</p>
- <p>The main considerations are aesthetics, since indoor wall units are visible in each room, and the fact that whole-home coverage requires multiple indoor units. Filters also need cleaning every four to six weeks. That said, for many homes the flexibility, efficiency, and zone control outweigh these tradeoffs.</p>
- <p>The number of zones depends on how many rooms you want to independently heat and cool, your home layout, and whether the mini-split is supplementing an existing system or serving as whole-home comfort. A single-zone system works well for an addition or problem room, while multi-zone systems can cover an entire home. Our team will assess your space and recommend the right configuration.</p>
- <p>In many cases, yes. A multi-zone ductless system can provide whole-home heating and cooling without ductwork. Whether it makes sense for your home depends on the size, layout, and whether you already have functional ductwork. For some homeowners a mini-split works best as a supplement to an existing central system rather than a full replacement.</p>
- <p>Mini-splits require regular filter cleaning every four to six weeks, keeping the outdoor unit clear of debris, and annual professional maintenance to check refrigerant levels, electrical connections, and overall system health. Consistent maintenance helps the system run efficiently and extends its lifespan.</p>
- <p>With proper maintenance, a ductless mini-split typically lasts 15 to 20 years, which is comparable to or better than a traditional central HVAC system. Regular filter cleaning and annual professional service are the biggest factors in reaching the upper end of that range.</p>
- <p>A single-zone mini-split installation is typically completed in one day. Multi-zone installations may take one to two days depending on the number of indoor units and the complexity of the refrigerant line routing. Installation only requires a small hole in the exterior wall for the line set, so disruption to your home is minimal compared to installing ductwork.</p>

Challenging job with my small attic space, but they did a great job of getting the whole new HVAC installed. Staff were polite and knowledgeable, they clearly wanted to do the job right and took pride in their work.

Kyle is the best! After hours call for AC not working. The company who installed the unit couldn’t get anyone to our house for over 5 DAYS! Fire and Ice was recommended by a coworker. I called and gave my info for an emergency house call. 10 minutes later Kyle called. Less than An hour later my AC was repaired! Pricewas super reasonable (especially considering it’s after 9 pm) No fuss, no gimmicks and super nice. Kyle you’re our hero!

The guys did a great job installing our new heating and cooling system. They were on time and courteous. Our techs Bryan and Brett answered all questions asked. There was no mess left over after they finished so all was good.

Great experience having all their people in our home to help us replace both 21 yr old heating & air conditioning units. They were recommended by our son since they did an efficient and quick job in their furnace breakdown. From Roger, who walked us through buying the units, to Floyd & Daniqua, the technicians that installed both Trane units, we found them very courteous, efficient and knowledgeable! We highly recommend Fire & Ice for your HVAC needs!!

Bryan and Nick were both very professional and friendly! When there is someone in your home typically it isn't like you can relax and go about your day but we were totally able to do just that. It is like they were not even here as they worked hard for 9+ hours to get the job done. Please tell them THANK YOU for being so awesome at what they do! Huge kudos to both gentlemen and you are lucky to have them on your team.
