Heat Pump Installation and Repair in O'Fallon, MO
Heat Pumps and Dual-Fuel Systems Sized for Your Home
At On Time Experts Heating, Air & Plumbing, we handle heat pump installation and repair, from sizing a new system or a dual-fuel setup with your gas furnace to fixing one that has stopped heating or cooling. Every option comes with upfront pricing.
What Heat Pump Installation and Repair Services Do We Provide?
Heat pump installation and repair is the sizing, installing and fixing of a heat pump, a system that cools your home in summer and heats it in winter by moving heat instead of burning fuel. Heat pump service from On Time Experts Heating, Air & Plumbing covers new systems and failed parts alike.
Most homes around O'Fallon still heat with a gas furnace, but heat pumps are showing up more often, usually when an old air conditioner is due. You need heat pump repair when the system blows cold air for long stretches in heat mode, stays iced over, runs nonstop or trips a breaker.
Replacement makes sense when an aging system keeps needing repairs. If one part failed on a younger system, we'll quote the repair.
What Is Included in Our Heat Pump Installation and Repair Services?
The work can include any of the following:
- Sizing and options: Size the system to your home and price heat pump only and dual-fuel options side by side.
- Installation: Remove the old equipment and install the outdoor unit, indoor coil or air handler, refrigerant lines and connections.
- Thermostat setup: Set up the thermostat, including the switch point between heat pump and furnace on dual-fuel systems.
- Repairs: Fix defrost controls, reversing valves, fan motors, capacitors (the part that gives a motor its starting boost), refrigerant leaks and auxiliary heat.
- Testing and cleanup: Test the system in both heating and cooling, protect your floors and clean up.
If you'd rather keep gas heat, see our Furnace Installation page, and a spring Air Conditioner Deep Clean and Tune-Up cleans the outdoor coil. Where a permit is required, the job is permitted.
Why Is Professional Heat Pump Installation and Repair Important?
A heat pump works in both seasons, so a sizing mistake or a neglected part shows up all year, not just in July.
Size the System to the House
A heat pump only works as well as it's sized. Too big, and it runs in short bursts that leave summer humidity behind. Too small, and it leans on backup heat more than it should in cold weather.
Correct sizing starts with a load calculation, such as ACCA Manual J, the industry sizing standard. It looks at insulation, windows, air leaks and layout, so the size fits the house instead of copying the old unit.
Choose Between Heat Pump Only and Dual Fuel
A dual-fuel system pairs a heat pump with a gas furnace. The heat pump cools in summer and carries most of the heating, and the furnace takes over on the coldest nights. For homes that already have gas, it's the common route.
An all-electric system uses auxiliary heat, heating elements in the indoor unit, as its backup instead of a furnace. Ameren Missouri's energy-efficiency programs may include rebates on qualifying heat pumps. Offers change, so ask what's current when you get a quote.
Keep It Clean in Both Seasons
Dirt, dust and debris are the number one cause of air conditioning and heating system breakdowns. A dirty outdoor coil or filter makes a heat pump work harder in every season, and regular maintenance can help it run efficiently and last longer.
What Happens During Heat Pump Installation and Repair?
New systems and repairs follow the same basic steps:
- Tell us what you need. A new system, or what you've noticed, such as ice that won't clear.
- Look at the setup. We check the outdoor unit, ductwork, electrical panel and, for dual fuel, your furnace.
- Size it or find the cause. We size a new system, or test the controls, refrigerant and backup heat.
- Review your options. You get the repair or the system choices, with upfront pricing, before any work begins.
- Do the work. We protect your floors, then install the new system or make the repair.
- Test both modes. We run heating and cooling, set up the thermostat and clean up.
You'll know how the system works before we leave.
Frequently asked questions
Yes, heat pump installation makes sense for many Missouri homes, especially as a dual-fuel system with a gas furnace for the coldest nights. The heat pump handles mild days efficiently, and the furnace carries the load when it's well below freezing.
Many newer models also keep heating at much lower outdoor temperatures than older ones. Correct sizing with the right backup heat makes either setup work.
The price of a heat pump installation for a 2,000 square foot house depends on more than square footage. Two homes that size can need very different systems because of insulation, windows, air leaks and layout.
A load calculation sets the size, and upfront pricing follows from there.
A heat pump installation's cost depends on the system type, size, efficiency rating and how much of your current setup can be reused. Ductwork, electrical upgrades and permits affect the total too.
Ameren Missouri rebates may lower the heat pump cost on qualifying equipment. A load calculation and upfront pricing from On Time Experts Heating, Air & Plumbing give you a real number for your home.
Heat pump repair is usually the better choice when the system is younger and a single part has failed, such as a capacitor, a contactor (the switch that powers the outdoor unit) or a fan motor.
Heat pump replacement is worth pricing when the system is older, needs a major part like the compressor, the pump that moves refrigerant, or keeps needing repairs. Ask for both prices side by side.
A heat pump needs repair when ice stays on the outdoor unit for hours, the system blows cold air for long stretches in heat mode, or it runs nonstop without reaching the setting. A short defrost cycle is normal. The reversing valve briefly flips the system to melt frost off the outdoor coil, and you may see steam while it clears.
If ice keeps building or auxiliary heat runs all the time, it's time to call for heat pump repair.
How Much Does Heat Pump Installation and Repair Cost?
Installation is priced by the system and the house, and repairs by the part that failed.
Factors that can affect the cost include:
- System type: Heat pump only or dual fuel with a gas furnace.
- Size and efficiency: The size from the load calculation and the efficiency rating you choose.
- Ductwork and coil: Whether the existing ductwork and indoor coil can be reused.
- Electrical work: Upgrades if your panel or wiring needs them.
- Repair details: The part that failed and whether refrigerant work is involved.
You'll get upfront pricing before any work begins, and nothing is scheduled until you say yes.
