What Impacts Heat Pump Cost the Most

Heat pump pricing can vary widely because no two homes or systems are exactly alike. Several key factors have the biggest influence on overall cost.

System type plays a major role. Standard air-source heat pumps are generally more affordable than ductless systems or dual-fuel heat pump furnace setups. Each option comes with different equipment requirements, labor demands, and efficiency capabilities.

Home size and layout also matter. Larger homes typically need larger or multiple systems to maintain consistent temperatures, which increases both equipment and installation costs. Homes with open layouts, multiple stories, or older construction may require additional design considerations.

Efficiency ratings directly affect price. Heat pumps with higher SEER and HSPF ratings usually cost more upfront but can reduce long-term energy use. Lower-efficiency systems may be less expensive initially but often result in higher operating costs over time.

Existing ductwork and electrical systems are another major factor. Homes with properly sized, well-sealed ducts and adequate electrical capacity generally cost less to upgrade. If ducts are damaged, undersized, or poorly designed, replacement or modification adds to the total cost.

Heat Pump Replacement Cost vs. New Installation

Replacing an existing heat pump is often more affordable than installing a brand-new system. In many replacement scenarios, the home already has compatible ductwork, refrigerant lines, and electrical connections, which helps control labor and material costs.

Replacement costs tend to increase when the existing system was improperly sized or installed. If airflow issues, comfort problems, or uneven temperatures are present, correcting those issues during replacement may raise the initial price but prevent ongoing performance problems.

New installations typically cost more because they may require new ducts, electrical upgrades, permits, or system design work. Homes transitioning from older heating systems often fall into this category.

While replacement can feel expensive, continuing to repair an aging or inefficient heat pump often leads to higher long-term costs and reliability issues.

Heat Pump Furnace Systems and Cost Considerations

A heat pump furnace system, also known as a dual-fuel system, combines a heat pump with a gas or propane furnace. These systems automatically switch between energy sources based on outdoor temperatures and efficiency needs.

Heat pump furnace systems usually cost more upfront due to added equipment and installation complexity. However, they can provide better performance in colder conditions while still offering energy savings during milder weather.

These systems often make sense for homeowners who want efficiency without sacrificing heating reliability during extreme temperatures. They are also useful in homes where a traditional furnace already exists and can be integrated into a hybrid setup.

Understanding whether a heat pump furnace is appropriate requires a professional assessment of climate conditions, fuel availability, and existing infrastructure.

When Heat Pump Costs Are Minor vs. a Sign of a Bigger Issue

Some heat pump costs are relatively minor and predictable. Straightforward replacements using the same system size and existing infrastructure typically fall into this category. These projects usually involve fewer surprises and shorter installation timelines.

More serious cost increases often indicate underlying issues. Common examples include deteriorating ductwork, insufficient electrical capacity, or systems that were never properly sized for the home. In these cases, the higher cost reflects necessary corrections rather than optional upgrades.

Switching from a furnace-only system to a heat pump can also increase costs, especially if electrical upgrades or duct modifications are required. While this may raise the initial investment, it often improves comfort, efficiency, and long-term reliability.

Long-Term Cost Factors Homeowners Often Overlook

Upfront heat pump cost is only part of the overall financial picture. Energy usage, maintenance needs, and system lifespan all affect long-term value.

Efficient heat pumps typically use less energy, which can reduce monthly utility bills. Over time, these savings can offset a higher initial investment. Maintenance costs are generally predictable when systems are properly installed and serviced regularly.

System lifespan and warranty coverage also matter. A properly sized and installed heat pump can last 15 years or more, while installation shortcuts often lead to premature failure and higher repair costs.

When to Involve a Professional HVAC Company

Professional evaluation is important before replacing a working but inefficient system, especially if comfort issues already exist. Large price differences between quotes often indicate differences in system design, installation scope, or long-term performance expectations.

A professional assessment is especially important when switching system types, such as moving from a furnace to a heat pump or considering a heat pump furnace setup. These decisions affect comfort, energy use, and future maintenance costs.

Proper sizing, airflow evaluation, and electrical assessment help ensure the heat pump cost reflects real needs rather than guesswork, protecting both performance and long-term value.

Plumbing

When the Hill Country gets a hard freeze, we hear the same question from homeowners across Fredericksburg, Kerrville, and nearby towns: why do you keep cabinets open in winter? It’s a simple step with real benefits. Leaving cabinet doors open allows warm indoor air to reach the plumbing tucked behind and beneath sinks, especially where pipes run along exterior walls. That airflow helps reduce the chance of frozen pipes, leaks, and costly water damage.

Think of it as part of a smart winter routine. Does opening cabinets keep pipes from freezing on its own? It helps a lot, but it’s most effective when you pair it with steady heat, pipe insulation, and a slow drip during deep freezes. If you need a hand getting your home ready, 72 Degrees Air Conditioning, Heating, and Plumbing is here with friendly guidance and dependable service.

Why Preventing Frozen Pipes Matters

Frozen pipes aren’t just inconvenient. Water expands when it freezes, and that pressure can crack fittings or split a line. Even a small break can release hundreds of gallons, soaking cabinets, floors, and walls. Repairs after a freeze are stressful and expensive, and the damage can linger.

Prevention is straightforward and affordable. Opening cabinet doors, insulating exposed sections, keeping a steady indoor temperature, and letting faucets drip during hard freezes all lower your risk. Why open cabinets when cold? Because that warm room air needs a clear path to the colder spaces behind your sinks.

How Open Cabinets Protect Your Pipes

Under-sink areas often sit apart from a room’s heated air. Behind the doors, cold from exterior walls or crawl spaces can settle and drop temperatures around supply lines and traps. When you leave cabinet doors open, you let warm air circulate, balancing the temperature and reducing cold pockets.

Here’s what that looks like in practice:

  • Airflow around plumbing: Open cabinets in cold weather move warmth into hidden spaces that otherwise get chilly fast.
  • Temperature balance: A closed cabinet can act like a little icebox near an exterior wall. Opening it helps equalize the space with the room.
  • Real-world results: During Hill Country deep freezes, homeowners who kept cabinet doors open and maintained steady heat often avoided frozen lines, while neighbors with closed doors saw slow flow or blockages.

Does opening cabinets keep pipes from freezing completely? Not always, but it significantly cuts the risk. Why keep cabinets open in winter? Because it’s an easy, low-cost step that supports your heating system and insulation, especially overnight.

Know Your Home’s Vulnerable Spots

Some areas freeze faster than others. In our region, a kitchen sink on a north-facing exterior wall, a bathroom along the outside of the house, or laundry lines near a garage can be more vulnerable.

Check these common cold zones:

  • Kitchen and bathroom sinks on exterior walls.
  • Laundry rooms, garages, and basements with limited heating.
  • Cabinets above crawl spaces or near slab edges.
  • Attic runs and hose bib connections.

Watch for slow water flow, extra-cold cabinet interiors, frost on pipes, or metallic “pinging” sounds as lines expand and contract. If you’re not sure where your pipes run, do a quick walk-through: trace visible lines, note wall orientation, look for drafts near penetrations, and feel for cold air at the back of cabinets. 72 Degrees can perform a winter readiness check and point out specific vulnerabilities before the next cold front.

Layered Strategies for Winter Protection

Leaving cabinets open in winter is one smart move. To get the best results, combine it with a few more steps so water keeps moving and pipes stay protected when temperatures dip.

Try these proven tips:

  • Insulate exposed pipes and consider heat cable for problem areas. Follow manufacturer guidelines and check connections each season.
  • Maintain steady indoor heat during a freeze. Avoid big thermostat setbacks that let pipes cool too much.
  • Let faucets drip on vulnerable lines—especially on exterior walls—when the forecast calls for lows near 20°F or below. A slow drip helps prevent ice plugs.
  • Seal drafts around pipe penetrations with caulk or foam to block cold air.
  • Check unheated spaces like crawl spaces, garages, and attics. Close vents or add temporary insulation where it’s safe.
  • Do simple prep: disconnect garden hoses, protect hose bibs, and confirm shutoff valves work before a cold snap.

Still wondering why open cabinets when cold? Open cabinets in cold weather make it easier for the heat you’re already paying for to reach the spots that need it most.

What To Do If Pipes Freeze

If you turn on a tap and the flow slows or stops, act quickly. First, open cabinets to let warm air in. Raise your thermostat a few degrees and, if safe, use a space heater in the room, away from combustibles and under supervision. Never use an open flame on pipes. If you suspect a burst—you hear water behind walls, see pooling, or notice a sudden drop in pressure—turn off the main water supply and call for help.

Our team responds promptly. We’ll locate the freeze, thaw lines safely, repair damage, and help you put preventive measures in place so you’re better prepared next time.

It’s a scary thought, but it’s a real question: can a furnace leak carbon monoxide when it’s turned off?

In Fredericksburg and across the Texas Hill Country, many homes rely on gas appliances to stay comfortable year-round. When something goes wrong with a furnace, boiler, or gas water heater, carbon monoxide (CO) can become a serious risk. CO is invisible, has no smell, and can harm people quickly.

This guide breaks down carbon monoxide furnace safety, what can cause CO problems, and the signs of a carbon monoxide leak so you know when to get help.

If you think your home may have a CO issue, leave the house and call for professional help right away.

What Is Carbon Monoxide and Why Is It So Dangerous?

Carbon monoxide (CO) is a toxic gas created when fuel (like natural gas or propane) doesn’t burn the right way. Because you can’t see or smell it, CO can build up without warning.

Breathing in CO reduces how much oxygen gets into your bloodstream. That’s why signs of carbon monoxide poisoning can feel like the flu at first, then become much more serious.

Can a Furnace Leak Carbon Monoxide When It’s Turned Off?

Most CO problems happen while a furnace is running, but a furnace can still contribute to CO danger even when it’s off, especially if combustion gases can’t vent out properly or if leftover gases linger and drift where they shouldn’t.

Here are common scenarios that can lead to a CO concern:

  • Venting problems that allow gases to backdraft into the home
  • Blocked or damaged flue pipes that prevent safe exhaust
  • A furnace issue that occurred earlier (while running) that still leaves unsafe conditions behind
  • Problems with other major gas appliances connected to venting (like boilers or gas water heaters)

Bottom line: if your CO alarm goes off, treat it as an emergency—whether the furnace is running or not.

Common Causes of Carbon Monoxide Leaks in Major Gas Appliances

Cracked heat exchanger (furnaces)

A heat exchanger keeps combustion gases separated from the air your home breathes. If it cracks from age, rust, or stress, CO can mix with indoor air.

Incomplete combustion

If a burner is dirty, the gas pressure is off, or the system isn’t getting the right airflow, fuel may not burn fully. That can increase CO production.

Blocked or failing venting

Vents and flues are supposed to carry exhaust outside. If they’re blocked by debris, damaged, or sized incorrectly, CO can back up into the home instead.

Poor draft or backdrafting

Sometimes exhaust gases get pulled back inside due to pressure issues in the home. This is especially important with older venting setups.

Signs of a Carbon Monoxide Leak in Your Home

People often search for the signs of carbon monoxide leak after something feels “off.” Watch for these red flags:

  • CO detector chirping or alarming
  • Stale or stuffy air that doesn’t improve with ventilation
  • Soot-like staining near vents or around the furnace area
  • Pilot or burner flame problems (yellow/orange instead of steady blue)
  • Condensation on windows near appliance areas (can be a clue, not a guarantee)
  • Symptoms that improve when you leave the house, then return when you come back

If your CO alarm goes off: get everyone outside immediately and call emergency services first.

Signs of Carbon Monoxide Poisoning

The signs of carbon monoxide poisoning can look like a cold or flu at first, which makes CO extra dangerous.

Common symptoms include:

  • Headache
  • Dizziness
  • Nausea or vomiting
  • Shortness of breath
  • Weakness or unusual fatigue
  • Confusion or trouble thinking clearly

Emergency warning signs can include fainting, chest pain, or loss of consciousness. If you suspect poisoning, get to fresh air and call emergency services immediately.

Carbon Monoxide Detector Installation: Where They Should Go

CO detectors are one of the simplest ways to protect your home, but placement matters.

For most homes, carbon monoxide detector installation should include:

  • One detector on each level of the home
  • One near sleeping areas (outside bedrooms)
  • Detectors placed according to manufacturer instructions (some are plug-in, some wall-mounted)

If you’re not sure what your home needs, we can help you choose the right setup and make sure detectors are installed correctly.

How to Prevent Carbon Monoxide Problems

Strong carbon monoxide furnace safety comes down to a few smart habits:

  • Schedule yearly inspections for your gas furnace, boiler, and gas water heater
  • Replace filters and keep mechanical areas clear for proper airflow
  • Don’t ignore strange smells, soot marks, or a burner flame that looks “wrong”
  • Make sure venting is intact and properly connected
  • Install and test CO detectors regularly (replace batteries on schedule)

What to Do If You Think You Have a CO Issue

If you suspect CO, don’t try to troubleshoot it yourself.

  1. Get everyone outside into fresh air
  2. If anyone feels sick, call emergency services
  3. Don’t re-enter the home until it’s cleared safe
  4. Once it’s safe, call a professional to inspect your major gas appliances (furnace, boiler, water heater) and venting system

If you’re in the Fredericksburg, Kerrville, or the Texas Hill Country and you’re concerned about a gas appliance, call 72 Degrees Air Conditioning, Heating, and Plumbing. We install and repair major gas appliances and can help you find the cause and fix it safely.

How Power Outages Affect Plumbing Systems

Plumbing isn’t just pipes and water. Many critical components depend on electricity to function.

When the power goes out, these systems may stop working:

  • Well pumps
  • Electric water heaters
  • Toilets with electric or ejector pumps
  • Sump pumps and basement drainage systems
  • Septic system pumps

If any of these fail during an outage, water service, sanitation, or flood protection can be lost entirely.

Will You Still Have Running Water During a Power Outage?

It depends on whether your home uses city water or a well.

Homes on City Water

Most municipal water systems rely on gravity, so water may continue flowing for a while. However:

  • Water pressure can drop
  • High demand may cause interruptions
  • Extended outages can affect supply

Homes on Well Water

Most Hill Country rural homes and STRs rely on wells.

  • No power means no pump
  • No pump means no running water
  • Without a generator, faucets, showers, and toilets stop working entirely.

For short-term rentals, this often leads to guest complaints, refunds, or canceled stays.

What Happens to Hot Water During a Power Outage?

Hot water availability depends on your water heater type and your water source.

Electric Water Heaters

  • Shut off immediately when power is lost
  • Stored hot water cools quickly
  • No recovery until power returns

Gas Water Heaters

  • Units with standing pilot lights may still heat
  • Units with electric ignition will not work
  • If your home uses a well, neither type will help once the pump stops. No water supply means no hot water—regardless of heater type.

Do Toilets Work Without Power?

Sometimes, but not always.

  • Gravity-fed toilets can flush as long as water is available
  • Toilets tied to septic ejector pumps or lift stations will not work
  • Continued use without power can cause sewage backups

In rural Hill Country properties, electric-assisted waste systems are common. During an outage, these systems need backup power to function safely.

What Happens to Septic and Sewer Systems?

Septic systems and some sewer connections rely on electric pumps to move waste away from the home.

Without power:

  • Wastewater can back up
  • Toilets and drains should not be used
  • Damage can occur quickly if usage continues

This is especially risky for STRs, where guests may not realize the system depends on electricity.

A plumbing inspection can identify whether your waste system is vulnerable before an outage occurs.

Can Power Outages Cause Frozen Pipes?

Yes—especially during winter outages. When power goes out, heating systems shut down. Without heat, exposed pipes can freeze and burst.

To reduce the risk:

  • Let faucets drip during freezing weather
  • Insulate pipes in crawl spaces, attics, and garages
  • Drain water lines if outages are expected to last overnight
  • Use a generator to keep heating systems running

Frozen pipe damage is one of the most expensive plumbing emergencies we see after winter storms.

Don’t Forget Outdoor Plumbing

Outdoor plumbing is often the first to fail during extreme weather.

Protect outdoor faucets by:

  • Insulating hose bibs
  • Wrapping exposed piping
  • Shutting off and draining exterior lines when possible

For STR owners, this should be part of your seasonal turnover checklist.

How a Backup Generator Protects Your Plumbing

A properly sized generator can keep essential plumbing systems running during a power outage.

With backup power, you can:

  • Keep your well pump operating
  • Maintain hot water access
  • Prevent sewage backups
  • Run sump pumps and prevent flooding
  • Keep heating systems active to avoid frozen pipes
