Heat pump guide
A heat pump heats and cools with one electric system, replacing both an air conditioner and a furnace in many homes. This guide explains why homeowners switch, how to read your situation, when timing matters, and what the main system choices involve.
The causes
Most foundation damage traces back to one of four sources. Identifying the cause determines which repair approach applies and whether other work, like drainage correction, needs to happen first.
Air conditioners and furnaces age on similar clocks. When both are past 12 to 15 years, one heat pump can replace both, which changes the cost comparison entirely.
Homes heated with oil, propane, or electric resistance pay the most per unit of heat. Heat pumps move heat instead of generating it, cutting consumption sharply for these homes.
Additions, bonus rooms, garages, and finished attics often sit outside the original duct design. Ductless heads solve room-level problems without redoing the whole system.
State and utility rebate programs, including income-based point-of-sale rebates in many states, can take thousands off a qualifying installation. Program rules and funding change, so verify before counting on them.
Urgency
Foundation problems exist on a spectrum. Most homeowners either underreact to serious movement or overreact to cosmetic cracks. Here is how to read the difference.
Current equipment heats and cools reliably and is under 10 years old. Learn your options and watch rebate programs so a future replacement is a planned decision.
Equipment is aging or operating costs are climbing. Getting quotes now means you choose the system calmly instead of during an outage.
A failed system in season forces fast decisions. You can still avoid the worst outcome, which is paying emergency pricing for another 15 years of the wrong system.
Identify your problem
Choose the closest match. The goal is to figure out which system conversation you should be having before pricing or calling an installer.
Your air conditioner and furnace are each 12 to 15+ years old and you are facing two replacements within a few years.
Replacing both with one heat pump often costs less than two separate systems over time. Price the heat pump against the combined replacement, not against either unit alone.The air conditioner died, the furnace still works, and you need cooling back quickly.
A heat pump can replace the AC and share duty with the existing furnace as a dual fuel setup. This is the most common entry point and keeps the gas furnace for the coldest days.You heat with oil, propane, or electric resistance and winter bills keep climbing.
These fuels are where heat pumps save the most. The quote should model your actual fuel costs against heat pump operating costs, not just quote equipment.The home has no ducts, or additions, bonus rooms, and upper floors never match the thermostat.
Ductless mini splits handle homes without ducts and problem rooms without touching the rest of the system. Zone count drives the price.Your current heat pump is 10 to 15 years old, repairs are stacking up, or it struggles in cold snaps.
A like-for-like heat pump replacement reuses ducts and wiring, which keeps cost down. Newer cold climate models may also fix the cold snap problem.No emergency, but you want off fossil fuels or are renovating and deciding what HVAC to install.
Planned projects get the best pricing and let you sequence electrical panel work, duct sealing, and rebate paperwork properly.What gets fixed
Foundation repair is not one thing. The right method depends on what is causing the problem and how far it has progressed. Each approach has a different scope, cost range, and set of exclusions.
A central heat pump that uses your existing ductwork to heat and cool the whole house. The most direct replacement for a furnace plus AC combination.
Best when ductwork is in usable shape. Duct sealing or modification is a separate line item worth pricing in the same visit.Pricing detail in the cost guideOne outdoor unit feeding one or more wall-mounted indoor heads. No ductwork needed, and each head is its own zone with its own remote.
Priced per zone. A single-zone setup for one room costs far less than a whole-home multi-zone system.Pricing detail in the cost guideA heat pump paired with a gas furnace. The heat pump handles most of the year and the furnace takes over on the coldest days, which keeps comfort in cold climates without oversizing.
Common when the furnace is newer than the AC. The control setup that switches between systems should be part of the quote.Pricing detail in the cost guideVariable-speed systems engineered to hold capacity well below freezing. They cost more than standard units but can carry homes in northern climates without backup heat.
Worth the premium where winter design temperatures are low. Ask for the unit's rated capacity at 5 degrees Fahrenheit, not just the efficiency rating.Pricing detail in the cost guideBuries a ground loop to exchange heat with the earth. The most efficient option with the longest equipment life, and the most expensive to install because of drilling or excavation.
A long-term play for owners staying put. Loop type, lot size, and drilling conditions drive the wide price range.Pricing detail in the cost guideNext steps
