Air Conditioning Repair, Maintenance and Installation

We are a Trane Comfort Specialist, but we service and maintain all brands. As experts in AC repair, maintenance, and installation, we can tackle any cooling problem. We recommend that you call us as soon as you notice any issues with your HVAC system. Scheduling timely service calls can help you to avoid more expensive repairs or a complete breakdown. We also offer preventive maintenance and service agreements that keep your cooling units performing at their best.

As your air conditioner starts to age, it becomes less efficient and is likely to break down frequently. It will be more cost effective to replace the system and avoid discomfort, high energy bills, and the expense of ongoing repairs. We’ll help you to select the ideal unit for your home or business. Our line of systems includes heat pumps, air conditioners, ductless mini-split systems and geothermal systems.

Heating Repair, Maintenance and Installation

When it’s cold outside, it shouldn’t make a difference in the way you view indoor comfort. We accept that it can be more challenging to manage indoor temperatures during winter, but that should never mean that you sacrifice comfort at any time. Warren-Hay will tackle any heating challenges you face.

We also specialize in heating maintenance and installation. When you’re ready for a new heating system, we can help you with a new furnace installation or replacement heat pump. We’ll provide the information you need to determine if a geothermal system is right for you. We’re not just HVAC contractors — we’re your partner in indoor comfort.
