AC replacement experts

From late spring to the dog days of August, you need to know that your AC will keep you comfortable regardless of how high the temperature spikes. 

If your air conditioner is nearing its twilight years, your electric bills are on the rise, or you have inconsistent cooling, it might be time to replace your AC.

As you consider your replacement options, we can help. We’ll evaluate your home to see if any changes or modifications have altered the size or style of system that best matches your needs. 

Our free estimates and upfront pricing make budgeting for a replacement AC easy and convenient. We’ll install your new unit according to industry standards and your satisfaction.

Experience you can trust

Choosing the right air conditioner is a major step toward summer comfort. If your equipment is too large, it will constantly cycle on and off, lose efficiency, and wear out prematurely. If it’s too small, it will never adequately cool your home. 

We provide the expertise you need to avoid both of these problems. Our certified service technicians are seasoned veterans at using Manual J calculations to determine the size you need for your home. 

We pair years of hands-on experience with ongoing training to ensure that our AC installations are professional, reliable, and affordable. Whether you’ve never had air conditioning in your home or you need to upgrade to a modern system, we can handle your summer comfort needs.

What to Expect During AC Installation

At Oncourse Heating Cooling Plumbing, we aim to make installing a new air conditioner as easy as possible. When you hire us for the job, we’ll:

  • Set an installation date that fits your schedule.
  • Carefully disconnect and remove your old AC.
  • Properly connect and install the new unit in its place.
  • Test the system in every way to ensure functionality.

Homeowners only need to ensure the area near the air conditioner is clear for our technicians and that pets are kept in a separate room for safety. Leave the rest to us.

Energy-efficient ac systems ensure long-lasting comfort

We install systems from Carrier, a company well-known for its efficiency, eco-friendly features, and innovative technology. The AC options we offer and install include heat pumps, ductless systems, and central air conditioning systems.

Regardless of which one you choose, you’ll get whisper-quiet operation, long-term durability, and outstanding energy-efficiency. Once we install your new AC, our technicians can help you keep it in tiptop shape through one of our cost-effective maintenance plans.
