Beyond the Estimate: What You Really Get with a Keystone HVAC Diagnostic

Jul 14

When you call Keystone for an HVAC inspection, you're not just getting a “free estimate”—you're getting a full-service diagnostic visit tailored to your home. We take a comprehensive approach to understanding your comfort system, because your HVAC setup is more than just an air conditioner—it's a machine, and like any machine, it requires detailed attention.

During a diagnostic visit, our trained technicians evaluate your system from top to bottom. We inspect duct work for airflow and leaks, check the thermostat and its communication with your system, review the condition of both indoor and outdoor units, and assess your home’s insulation and heating/cooling loads. Whether it's a modern mini-split system or a 20-year-old split unit, we treat each system with the care it deserves.

At Keystone, we believe in honest, informed service. That means we won’t push a replacement unless it's truly needed. Sometimes a simple tune-up is all that’s required to restore comfort. In fact, many of our customers are surprised to learn their systems are in good working order and just need a small adjustment, a filter change, or a thorough cleaning.

On the other hand, if there’s a more serious issue—like rodent-damaged ductwork (something we’ve recently found in the field)—we provide a clear explanation and practical solutions. From system replacement to duct sealing and insulation repairs, we provide a full report with every visit, just like a trusted local mechanic would do for your car.

How Do You Know When to Call Keystone?

You don’t have to wait for a full system failure to give us a call. Here are a few signs it might be time for a diagnostic visit:

Your system isn’t cooling or heating like it used to
You notice higher-than-usual energy bills
Some rooms feel too hot or too cold
You hear unusual noises or notice new odors
It’s been more than a year since your last inspection

These symptoms may seem small, but they can point to larger issues if left unaddressed. Early detection means fewer surprises and lower costs down the line.

So, if your home isn’t feeling as cool as it should this summer, it might be time for a diagnostic visit. Let Keystone take a look, give you the facts, and help you make an informed decision.
