We are a locally owned and operated HVAC company based in Fort Wayne, Indiana, serving all of Allen County with ambitions to expand. We noticed a growing trend of large corporate HVAC firms taking over the space that once was filled by smaller, locally owned companies. Witnessing this, we felt compelled to start our own HVAC company to reinstate the essence of local, personalized, and affordable service.\nWe believe that HVAC service should not just be a transaction, it should be a relationship. Instead of upcharging and taking advantage of customers, our goal is to provide a cost-effective and personal experience. We care about our community and strive to keep your home comfortable at a fair price.

Heating and Air Conditioning questions, answered by experts

Capacitors are the most frequent part of an HVAC system to experience failure. These components are crucial for starting the motors that power the fans and compressor, but over time, they may become worn or fail due to electrical surges or regular wear and tear. When capacitors malfunction, HVAC systems may experience decreased heating or cooling efficiency, or even total system failure. Replacement or maintenance of capacitors is a common requirement for the optimal functioning of HVAC systems.

Yes, government incentives and programs are available to encourage energy-efficient upgrades in many regions. These incentives may include tax credits, rebates, grants, and low-interest loans for homeowners who invest in energy-efficient improvements such as HVAC system upgrades, insulation, and efficient windows. The availability and specific details of these incentives can vary by location, so check with your local government or utility company to explore your options.

Winterizing can still help you save money on energy costs and help prepare your AC for its work next year when you turn it back on. We suggest planning for at least some maintenance, even if winters are mild in your area.

If your AC suddenly stops working, the first thing to check is your thermostat settings. Ensure the thermostat is set to the appropriate temperature and mode (cooling). Sometimes, a simple adjustment or replacing the batteries in the thermostat can resolve the issue. If that’s not the issue, look to see if the circuit breaker tripped. These basic checks can often identify simple fixes before you need to call for professional assistance.

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.
