Is your heating or cooling system over 12 years old? Are you facing frequent breakdowns or skyrocketing energy bills? It might be time for a new installation. Comfort By Design specializes in complete HVAC system replacements for residential and commercial properties. We guide you through every step—from selecting the right size and efficiency rating to professional removal of your old unit and seamless installation of the new one.

We begin with a detailed load calculation and home assessment. This ensures your new system is neither oversized (which cycles on and off too often) nor undersized (which runs constantly and never catches up). We only recommend systems from trusted, energy-efficient brands that deliver reliable performance and long-term savings. After installation, we test everything: airflow, ductwork, thermostat calibration, and safety controls. We also clean up thoroughly, leaving your property spotless.

Our team stays current with the latest HVAC technology and local building codes, so you can rest easy knowing your new system is installed correctly the first time. Plus, we help you navigate any available rebates or financing options to make the investment more manageable. Call us for a free, no-pressure estimate on your next installation.

Prevent costly breakdowns and extend the life of your heating and cooling system with our routine inspection and maintenance plans. At Comfort By Design, we believe that regular tune-ups are the best investment you can make for your home or business. Our certified technicians perform a 20+ point inspection during each visit, covering everything from filter replacement and coil cleaning to checking refrigerant charge, testing electrical components, and lubricating moving parts.

For homeowners, our annual maintenance plan helps you avoid midsummer AC failures and winter furnace issues. We'll send you a friendly reminder when it's time to schedule, and you'll get priority service and a discount on any repairs that might be needed. For commercial clients, we offer flexible scheduling that won't disrupt your business hours, ensuring your HVAC system stays efficient and reliable for your employees and customers.

Routine maintenance also improves indoor air quality, reduces energy waste, and keeps your warranty valid. Don't wait for something to break—let us help you stay ahead of problems with professional, affordable HVAC inspections today.
