Heat Pump Repair
Heating fine but won't cool — or the other way around? That points to a specific, findable problem.
Overview
What this service covers
Heat pump problems often show up differently than straight AC problems — a system that heats fine but won't cool (or vice versa) almost always points to the reversing valve, not a generic refrigerant issue. We diagnose the actual failure specific to how heat pumps work instead of treating it like a standard AC repair.
A heat pump that heats but won't cool isn't a mystery to us — it's one of the most recognizable heat-pump-specific failures there is, and we diagnose it as one instead of guessing with standard AC logic.
What's Included
- Diagnosis specific to heat pump components (reversing valve, defrost cycle, dual-mode refrigerant flow)
- Repair or replacement of the failed component
- Testing in both heating and cooling modes before we call it done
- Clear pricing before any work begins
Common Problems This Solves
- Heat pump heats but won't cool, or cools but won't heat
- System stuck in one mode regardless of thermostat setting
- Ice building up on the outdoor coil
- Short cycling or running constantly in either mode
- Reduced heating or cooling performance compared to before
Equipment & Systems
- Heat pumps
- Outdoor condensers
- Air handlers
- Thermostats
How We Diagnose It
We start with which mode is actually affected — heating, cooling, or both — since that alone narrows the likely cause significantly. From there we test the reversing valve's operation, check refrigerant charge and pressure in both modes, inspect the defrost cycle and defrost board if ice is involved, and check electrical components specific to mode-switching. A heat pump diagnosed like a standard AC system often gets the wrong answer.
Our Process on This Job
Once we've confirmed the actual cause, we explain what's failed and what the repair involves — a reversing valve replacement is a more involved repair than a capacitor swap, and we'll be upfront about that cost difference before you approve anything. Every repair gets tested in both heating and cooling modes before we consider the job done, since a fix that only gets verified in one mode can hide a problem that shows up later.
When to Call
When to call SegtVision
Call us if your heat pump won't heat, won't cool, is stuck in one mode, ices up on the outdoor coil, or is cycling more than it used to.
The Process
What to expect
The same straightforward process on every job, every time.
We Assess the Issue
We look at what's actually going on before recommending anything — no guessing, no upselling.
You Get Clear Pricing
We explain what we found and what it costs before any work begins. Nothing starts without your okay.
We Do the Work
We treat your property like our own — clean work, no shortcuts, and respect for your time.
We Test & Explain
Before we leave, we confirm everything works and walk you through what was done in plain language.
Why It's Worth Doing
- Correct diagnosis from a technician who checks heat-pump-specific components, not just standard AC parts
- Restores both heating and cooling instead of a partial fix
- Avoids paying for a refrigerant recharge when the real issue is a mechanical valve
- Extends the system's life by catching mode-switching problems before they strain the compressor
- Tested in both modes before we leave, not just the one you called about

FAQ
Frequently asked questions
Why would a heat pump work in one mode but not the other?
That's a classic sign of a reversing valve problem — the component that switches the system between heating and cooling. It's a heat-pump-specific part that doesn't exist on a standard AC system, so it needs a technician familiar with how heat pumps actually work.
Do you repair heat pumps for both homes and small businesses?
Yes, heat pump repair for homes and small businesses across Sarasota, Bradenton, Venice, and Lakewood Ranch.
Will I get pricing before any repair work begins?
Yes — we diagnose the actual cause first and explain the repair options and cost before doing any work.
Is ice on the outdoor unit always a problem?
Some frost during a normal defrost cycle is expected. Heavy ice buildup that doesn't clear, or ice in cooling mode, points to a real issue worth having checked.
Are manufacturer warranties included?
Warranty coverage depends on your specific equipment — we'll help confirm what applies before recommending a repair.
Could the price change once you're into the repair?
Occasionally, if we find something else wrong once we're into the system, we'll quote it separately before proceeding.
Maintenance Tips
Keep it running smoothly between visits
A few things you can do between visits to keep small issues from becoming big ones.
- Pay attention to whether a problem is mode-specific (only heating, only cooling) and mention that when you call
- Some outdoor coil frost during defrost cycles is normal — heavy or constant ice is not
- Don't ignore a system that's stuck in one mode assuming it'll reset itself
- Keep the outdoor unit's airflow clear year-round since heat pumps work in both directions
- Ask about a maintenance visit before each season if your system handles both your heating and cooling
Important Notes
Permits are not included unless specifically stated on your estimate. Manufacturer warranty must be verified by equipment and manufacturer — we'll confirm what applies to your specific unit. Hidden conditions, code upgrades, electrical upgrades, drywall or paint repair, major ductwork, and additional materials discovered once a job is underway may be quoted separately before we proceed. SegtVision coordinates HVAC and electrical work performed under separately licensed contractors — HVAC/mechanical work under Florida Certified Mechanical Contractor License #CMC1251604, and electrical work under Florida Electrical Contractor License #EC13013837.
