System behavior matters
We sort out whether the problem is airflow, controls, refrigerant performance, defrost, or setup. Then we test the system in the mode it is supposed to be using.
What we check
Heat pumps move heat instead of creating it the way a furnace does. That means the diagnosis has to account for both heating and cooling behavior.
What to expect
The first visit is a safety-first evaluation of the system, controls, and operating behavior before any repair work begins.
Diagnostic fee
A clear explanation before any work begins.
The $220 diagnostic fee covers a thorough, safety-first evaluation of the heat pump, its controls, and the conditions that affect performance. You get a clear explanation of what we found and repair options before any work begins.
Confirm how the unit is operating in the current mode.
Check the thermostat signal and setup against the equipment.
Look for frost, ice, and recovery problems at the outdoor unit.

Heat pumps in plain language
A heat pump heats and cools with the same equipment, so the symptom you notice does not always point to the same kind of problem.
A furnace makes heat. A standard air conditioner moves heat out of the home. A heat pump does both jobs with the same equipment, which is why a winter complaint and a summer complaint can still trace back to the same control issue, airflow problem, or outdoor unit.
That is also why the symptom can be misleading. Weak winter heating, slow summer cooling, heavy frost, or backup heat running too often can all point to different parts of the same system. We start with the current operating mode, then check the thermostat call, airflow, and indoor and outdoor response so you get an answer that matches what the system is actually doing.
Common heat pump problems
These are the kinds of changes that usually lead to a service call, and each one can point to more than one root cause.
When the system runs but the house never seems to settle, the issue may be airflow, thermostat setup, or heat-transfer performance. We check those together so a weak-heating complaint is not treated like a furnace issue and a weak-cooling complaint is not blamed on the thermostat too early.
Some frost on the outdoor unit can be normal in winter. What is not normal is heavy ice that lingers, repeated recovery cycles that never seem to restore comfort, or a system that loses output every time the weather turns colder. We check the cycle that clears frost from the outdoor unit, the outdoor conditions, and the operating performance so you know whether the issue is winter behavior or a service problem.
Heat pumps often have backup heat for colder weather or higher demand. If it is running too often, you may notice longer run times, comfort swings, or higher utility costs. We sort out whether the equipment is struggling or whether the settings and controls are calling for backup heat too often.
Because heat pumps depend on the right settings and control signals, a setup problem can look like failed equipment from the outside. A home may feel cold, the air may feel cooler than expected, or the system may seem to switch modes unpredictably. We test the thermostat signal and wiring before deciding the issue is a larger repair.
Safe checks before you call
These checks can help you describe what you are seeing when you call, which makes the phone conversation more useful and helps us prepare for the visit. If the issue feels urgent, comfort is dropping fast, or the system is not responding at all, call right away instead of troubleshooting further.
Make sure the thermostat is calling for the mode you actually want and that the temperature you want the home to reach is clearly separated from the current room temperature.
A dirty filter, blocked return, or closed supply register can make the system look weaker than it is. If airflow is restricted, the equipment can struggle in both heating and cooling mode.
Notice whether there is a light layer of frost or a thicker sheet of ice that is not clearing. That gives us useful context for the visit, especially in winter.
If the system is not heating or cooling well, backup heat is running constantly, or the home is becoming uncomfortable during harsh weather, it is worth calling instead of waiting for the pattern to repeat.
What the visit should tell you
A good service visit should leave you with a clear explanation, not a vague impression that the system is complicated.
The most useful outcome of a heat pump service call is a cleaner decision. You should know whether the issue starts with controls, airflow, heat transfer, or a larger equipment problem, and you should know whether the next step is a repair, more testing, or a bigger conversation.
That matters because heat pump symptoms overlap. Frost, weak output, and heavy backup-heat use can come from more than one place. We narrow the problem to the most likely root cause, explain it in plain language, and show you the next practical step before any work begins.
Repair options and next steps
The right recommendation depends on what the system is doing now and what the diagnosis shows, not on a one-size-fits-all script.
Some heat pump calls end with a straightforward repair. Others uncover a combination of smaller issues that add up to poor comfort. In both cases, the recommendation should be specific: what failed, why it matters, and what repair path makes sense for this system.
If the issue is tied to settings or wiring, we say that. If the issue is tied to airflow or operating performance, we say that too. If the findings point to a larger conversation, we would rather tell you plainly than stretch a smaller repair beyond what it can realistically solve.
Why year-round service matters
A heat pump does not wait for the perfect time to show you that something has changed.
Some homeowners notice the issue during the first cold stretch. Others notice it during the first hot week. That does not always mean the problem started that day. It often means the season change finally exposed a weakness that was already there.
That is useful information. If the heat pump now takes longer to settle the house, leans too hard on backup heat, cools more slowly, or shows frost patterns that look different than before, the system is telling you something changed. A service visit helps you sort out whether that change is minor, repairable, or part of a bigger decision before the next weather swing puts more pressure on it.
The team behind the visit
When someone shows up to diagnose your heat pump, you should know what to expect from the team behind the visit. CDA Heating & Cooling is licensed, bonded, and insured in both Idaho and Washington, with 20+ years of HVAC experience across residential and commercial systems.
We serve homeowners on both sides of the state line — Spokane County in Washington and Kootenai, Bonner, and Shoshone Counties in Idaho. The $220 diagnostic fee means you know the cost of the visit before we arrive, and there is no pressure to commit to a repair until you have heard the findings. Owner Eddie Proulx personally oversees diagnostic quality, so the process stays thorough and the explanation stays clear.
We confirm the operating mode first so the repair path matches the way the system is actually being used.
We ask what the system is doing, what mode it is in, and when the problem started.
We test the thermostat, airflow, outdoor unit, and defrost-related behavior.
You get a clear explanation of what failed and the most practical next step.

Talk to the teamCommon signs include weak heating or cooling, unusual cycling, icing, or a thermostat that seems to be calling for the wrong behavior. Diagnosis confirms whether the issue is controls, airflow, refrigerant, or defrost.
A heat pump can blow cooler air while it is still working in certain conditions, but a comfort problem can also point to a control, airflow, or mode issue. We test the system in context instead of guessing.
Defrost helps the outdoor unit recover when frost builds up. If that cycle is not behaving correctly, the system can lose performance and comfort. We check that behavior when winter operation looks off.
Yes. A heat pump depends on the control signal being correct. If the thermostat setup or wiring is wrong, the system can behave like the equipment is failing even when the root problem starts at the controls.
The $220 diagnostic fee covers the visit, the evaluation, and a clear explanation of findings. If a repair is needed, that is quoted separately after the diagnosis so you know exactly what you are agreeing to. There are no hidden fees.
Modern heat pumps are designed to perform in cold climates. At very low temperatures, the system may rely on auxiliary or backup heat to maintain comfort. During a diagnostic visit, we check both heating and cooling modes so the system is ready for the conditions it will actually face.
Yes. CDA Heating & Cooling serves homeowners across the confirmed Idaho and Washington service areas listed on the site.
