Year-Round Comfort from One Efficient System
A heat pump is one of the most efficient ways to keep a home comfortable all year — moving heat rather than burning fuel to warm your home in winter and cool it in summer, all from a single system. But that efficiency depends entirely on proper sizing, correct installation, and regular upkeep. When a heat pump is neglected or was never set up right, the signs show up fast: it blows cold air in heating mode, won't switch between heating and cooling, ices over in winter, short cycles, or quietly pushes your energy bills higher. The good news is that most of those problems are fixable — and many are avoidable with the right service.
LaVergne's provides complete heat pump services including heat pump installation and replacement, repair and diagnostics, seasonal maintenance and tune-ups, ductless mini-split systems, and efficiency upgrades — keeping homes comfortable in every season across Birmingham and the surrounding communities.
What to Look for in a Heat Pump Contractor
A heat pump only delivers its promised efficiency and comfort when it's sized, installed, and serviced correctly. It heats and cools from one system, which means the right contractor has to understand load calculations, refrigerant charge, defrost cycles, and both operating modes. A rushed or undersized install wastes energy, shortens the equipment's life, and leaves rooms that never feel right. You want a licensed, insured HVAC contractor who does the math up front and gives you an honest price before the work begins — not a handyman guessing at it.

Replace →Heat Pump Repair
Blowing cold in heat mode, won't switch between heating and cooling, iced-over outdoor unit, short cycling, or rising bills. We diagnose whether it's refrigerant, the reversing valve, defrost controls, or airflow — and fix it.
Repair →Maintenance & Tune-Ups
Seasonal tune-ups keep your heat pump efficient and reliable. We clean coils, check refrigerant charge, test defrost, inspect electrical components, and replace filters to prevent breakdowns and lower run costs.
Tune Up →Ductless Mini-Splits
Ductless mini-split heat pumps deliver quiet, zoned comfort to additions, bonus rooms, garages, and homes without ductwork. We size, install, and service single- and multi-zone systems.
Explore →Refrigerant & Defrost
Low refrigerant and defrost problems rob a heat pump of efficiency and can freeze up the outdoor unit. We find and repair leaks, recharge to spec, and correct faulty defrost controls to restore full performance.
Diagnose →Heat Pump Trouble? Ready to Upgrade?
Heat pump installation, repair, and maintenance across Bellingham, Mount Vernon, Anacortes and all surrounding areas.
Most Common Heat Pump Problems We Solve
Heat pump problems tend to start small and grow into big energy bills. The system blows cool air when it should be heating, won't switch modes, freezes up outside, or runs constantly without ever reaching the set point. Caught early, most of these are straightforward fixes. Here are the four issues we're called out for most.
Before replacing any expensive component, we diagnose the true cause — refrigerant, reversing valve, defrost, or airflow — so you only pay for the repair you actually need.
Blowing Cold in Heat Mode
Low refrigerant, a stuck reversing valve, or a faulty defrost cycle can leave your heat pump blowing cool air when you need heat. We find the cause and restore proper heating.
Fix It →Won't Switch Modes
A heat pump stuck in heating or cooling usually points to a failing reversing valve or a control issue. We test the valve and controls and repair what's actually failing.
Diagnose →Iced-Over Outdoor Unit
A little frost is normal; a fully iced-up unit is not. Defrost faults, low refrigerant, or airflow blockages are common causes. We clear it and fix the reason it's freezing.
Defrost →Short Cycling & High Bills
Constant on-off cycling and climbing energy costs signal an oversized system, low charge, a dirty coil, or a failing sensor. We tune, repair, or right-size to restore efficiency.

Why Professional Heat Pump Service Matters
A heat pump is a precision system that heats and cools by moving refrigerant, so its performance depends on getting the details right — correct sizing, proper refrigerant charge, clean airflow, and a working defrost cycle. When any of that is off, the system wastes energy, ices up, short cycles, and wears out its compressor years early. A rushed handyman install or a neglected unit almost always costs more in the long run than doing it right the first time.
Licensed HVAC technicians size the system to your home, charge it to spec, test heating, cooling, and defrost, and keep it maintained season after season. The result is lower energy bills, steady comfort, and equipment that lasts as long as it should.

Heat Pump FAQs
Common heat pump questions answered by our licensed HVAC specialists serving Whatcom and Skagit Counties.
How does a heat pump heat and cool with one system?
A heat pump moves heat rather than creating it. In summer it pulls heat out of your home; in winter it reverses and pulls heat from the outside air into your home. That single system replaces both a furnace and an air conditioner — and uses far less energy doing it.
Do heat pumps work in cold weather?
Yes. Modern heat pumps are designed to pull heat from the air even in freezing temperatures, and cold-climate models perform well through hard winters. Proper sizing and, in some homes, a backup heat source keep you comfortable on the coldest days.
Why is my heat pump blowing cold air in heating mode?
Common causes are low refrigerant, a stuck reversing valve, or a defrost cycle that isn't working right. Sometimes it's simply the unit defrosting normally. We diagnose the exact cause and restore proper heating.
Why is my outdoor unit covered in ice?
A light frost is normal and clears on its own during defrost. A unit fully encased in ice usually means a defrost fault, low refrigerant, or restricted airflow. Don't chip at it — call us to clear it and fix the underlying reason.
How often should a heat pump be serviced?
Because a heat pump runs year-round, we recommend two tune-ups a year — one before cooling season and one before heating season. Regular maintenance keeps efficiency high, prevents breakdowns, and extends the life of the system.
How long does a heat pump last?
A well-maintained heat pump typically lasts 12 to 15 years, sometimes longer. Skipped maintenance, an incorrect charge, or a poor original install shorten that considerably — which is why professional service pays off.
Should I repair or replace my heat pump?
If your unit is over 10 to 12 years old, needs frequent repairs, or your energy bills keep climbing, replacement is often the better value. We give you an honest comparison of both options so you can decide with confidence.
Are ductless mini-splits worth it?
For additions, bonus rooms, garages, and homes without ductwork, absolutely. Ductless mini-split heat pumps deliver quiet, efficient, zoned comfort without the cost and disruption of installing ducts. We'll help you decide if one fits your home.
What areas do you serve?
We install, repair, and maintain heat pumps across all of Whatcom and Skagit Counties including Bellingham, Mount Vernon, Anacortes, Burlington, Sedro Woolley, Ferndale, Lynden, and surrounding areas.
