Questions and Answers

My HVAC system isn't heating or cooling my Kennewick home evenly. Could this be an airflow issue?

Yes, uneven heating or cooling is often a sign of restricted airflow, which is common here due to dust and debris clogging vents over time. At Horst Heating, we start by thoroughly inspecting your ductwork and vents for blockages. With experience designing thousands of duct systems, we can diagnose whether it's a simple cleaning issue, a duct design flaw from the original construction, or a problem with the system itself. We'll provide a clear explanation and recommend the most practical solution to restore comfort efficiently.

My system is aging. Should I repair it or start planning for a replacement?

This is a common question we help Kennewick homeowners with daily. Our philosophy, honed since 1992, is to help you get the most value from your current system. We perform a thorough evaluation of the repair cost, your system's age, and its efficiency. We'll give you an honest assessment of whether a repair makes sense or if replacement is the more economical long-term choice. We believe in this approach so strongly that we often recommend getting a second opinion to ensure you have confidence in the decision.

I'm concerned my HVAC system might be the wrong size for my home. How can you tell?

Proper sizing is critical for comfort and efficiency, especially with our Tri-Cities climate. An oversized or undersized system leads to short cycling, high bills, and wear. Drawing from our experience installing systems in thousands of new construction homes, we perform a detailed load calculation. This isn't a simple rule of thumb; it considers your home's square footage, insulation, window placement, and more. We'll determine if your current system is correctly sized and provide straightforward options if a change is needed.
