Preventative Maintenance

We believe that everyone deserves the very best service available. That's why we suggest a proactive Preventative Maintenance program.

We continually invest in the tools and training necessary to remain at the top of our field. Whether you need help with your heating or cooling system, you can count on Clark Heating & Cooling for the safest, healthiest, most comfortable and efficient solution possible.

Using state-of-the-art diagnostic tools and having 38 years of experience in the business, we can solve almost any problem you may experience. In most cases, we will offer you at least three choices when you are considering major repairs or replacement of your heating or cooling system.

We charge by the job, not by the hour. Therefore, you will know the price for most repair or replacement work before we begin the work. No surprises. For your peace of mind, we offer the best maintenance agreements and product warranties in the business. You can always count on us!

We also clean / service Humidifiers and AccuClean systems in our Preventative Maintenance program at an additional cost.
