New Installation

A proper HVAC installation begins with understanding your home. We calculate the ideal system size based on square footage, insulation, and airflow—ensuring even, efficient heating and cooling throughout your space. Whether you’re building new or upgrading an older system, we design and install solutions that deliver long-term comfort and cost savings.


Our installation process includes detailed assessments, professional setup, and a full performance test before we leave your home. From Circleville to Ashville, we help homeowners enjoy worry-free comfort from day one.

Upgrade or Replacement

When your old system starts showing signs of wear—uneven temperatures, rising bills, or loud operation—it may be time for an upgrade. We’ll walk you through modern Day & Night high-efficiency systems, explaining features like variable speed motors, smart controls, and energy-saving modes. Replacing outdated equipment often lowers energy bills and enhances comfort instantly. Plus, with our financing options, it’s easier than ever to make the switch.

Preventive Maintenance

Routine maintenance is the secret to keeping your HVAC system running like new. Tarbill’s tune-up programs include comprehensive cleaning, safety checks, and component testing. Regular inspections not only extend system life but also reduce unexpected breakdowns and maintain energy efficiency.

Indoor Air Quality

The air inside your home can impact your health, comfort, and even your energy bills. We offer advanced solutions such as HEPA filtration systems, UV germicidal lights, and whole-home humidifiers. These systems reduce allergens, kill airborne bacteria, and balance humidity for a more comfortable, breathable home environment.

Air Duct Sealing

Leaky ducts can waste up to 30% of your system’s airflow. Our duct sealing service pinpoints leaks, reinforces weak areas, and improves your system’s overall efficiency. Better airflow means faster heating and cooling, more balanced temperatures, and lower energy use.
