Why Greater Houston Homeowners Choose Heat Pump Installation

One System for All Seasons, Not Two

Traditional homes have a furnace for winter and an AC unit for summer—two separate pieces of equipment, two sets of maintenance calls, two warranties to track. A heat pump handles both heating and cooling through a single, integrated system. In winter, the heat pump pulls warmth from outside air (even on cold days) and delivers it indoors. In summer, it reverses and cools just like an air conditioner. One system, one service relationship, lower operating costs.

Superior Efficiency Over Furnace-Plus-AC

A ducted heat pump running on electricity is significantly more efficient than a gas furnace plus a separate AC unit. Heat pumps use the refrigeration cycle to move heat rather than burning fuel—meaning you get consistent, efficient year-round climate control. Over 15–20 years, you’ll see meaningful energy savings, especially if electricity rates in your area are favorable compared to natural gas.

Dual Energy Source Option for Houston Winters

Most heat pumps in Houston climates operate efficiently in heating mode throughout winter. If a cold snap drops outdoor temps below freezing (rare but possible), your heat pump includes backup electric heating (auxiliary heat) so you’re never without warmth. We discuss supplemental heat during installation so you understand how your system responds to extreme cold.

Authorized Dealer Expertise

We install Armstrong and Samsung heat pump systems. Both brands deliver quiet, efficient heating and cooling with advanced controls and strong manufacturer support. Armstrong systems are known for reliability and efficiency; Samsung offers competitive efficiency with excellent warranty coverage. We’ll help you select the brand and model that matches your home and budget. Every installation also carries LMH Services’ 1-year labor warranty, with extended parts-and-labor plans available through JB Warranties.

Proper Sizing Ensures Balanced Year-Round Performance

Heat pump sizing requires different thinking than AC-only units. We calculate both your cooling load (for summer) and heating load (for winter) to ensure the system handles both seasons efficiently. A system sized for cooling alone may under-heat in winter; a system sized for heating alone may cycle inefficiently in summer. We size for balanced, efficient performance year-round.

Our Process

Our Heat Pump Installation Process

From dual-season load calculations to comprehensive testing, every step ensures your heat pump delivers efficient heating and cooling year-round.

Heat pump installation - outdoor AC condenser unit

We evaluate your home’s climate control needs in both seasons. We measure square footage, insulation quality, window types and orientation, existing ductwork layout, and your comfort preferences. We also review your utility bills to understand historical heating and cooling energy usage—this data gives us real-world context for how much heat or cooling your home typically needs.

Using this assessment, we calculate two separate load calculations:

  • Cooling Load (Summer) — How much cooling capacity you need to maintain comfort on Houston’s hottest days (100°F+ outdoor temps, high humidity). We size the heat pump’s cooling capacity to match or slightly exceed this load.
  • Heating Load (Winter) — How much heating capacity you need during a cold snap (40°F or below outdoor temps). Heat pumps extract heat from outdoor air; the colder it gets, the less heat the system can extract, so adequate heating capacity is critical. We ensure your heat pump can meet your home’s heating demand without over-relying on auxiliary (electric) heat, which is less efficient.

Proper sizing for both seasons means your heat pump runs efficiently year-round, never short-cycling in summer or struggling to meet heating demand in winter.

We present heat pump options at different efficiency levels and discuss the long-term cost-benefit of each:

  • Standard Efficiency Heat Pumps — Entry-level efficiency ratings (SEER 14, HSPF 8–9). Lower upfront cost; moderate seasonal efficiency. Good for homeowners on a tight budget or planning shorter ownership.
  • High-Efficiency Heat Pumps — Premium ratings (SEER 16–18, HSPF 9–10). Significantly higher efficiency and lower operating costs over 15+ years. Higher upfront investment but stronger payback in energy savings, especially in climates with long heating or cooling seasons.
  • Advanced Smart-Enabled Heat Pumps — Latest-generation systems with app control, learning capability, and integration with smart home systems. Quieter operation, better humidity control, and granular energy management. Premium pricing, but excellent if you value convenience and maximum efficiency.

We also discuss thermostat options: smart thermostats provide app control and learning features; basic programmable thermostats offer scheduling without app access. Most heat pump installations benefit from smart thermostats since they let you optimize heating and cooling schedules remotely.

We explain financing through Wisetack, answering questions about monthly payments and interest rates so you understand the total cost of ownership.

Once you select equipment, thermostat, and financing terms, we order the system and confirm installation dates.

We evaluate your existing ductwork to ensure it’s compatible with heat pump operation. Heat pumps require slightly different duct conditions than AC-only systems because they operate year-round and must distribute heated air efficiently in winter.

We check for:

  • Duct Leaks and Sealing — Leaky ducts waste heated air in winter and cooled air in summer. We seal all visible leaks with mastic sealant or metallic tape to maximize efficiency.
  • Proper Insulation on All Ducts — In winter, return ducts passing through cold spaces (attics, garages) must be insulated to prevent heat loss. We ensure insulation is adequate so your heat pump’s output reaches your living spaces, not your walls.
  • Duct Sizing for Heat Pump Airflow — Heat pumps require adequate duct sizing for both heating and cooling airflow. If ducts are undersized, we may recommend enlarging them to ensure unrestricted flow, which is critical for efficient operation in both modes.
  • Blockages or Restrictions — We clear any debris, collapsed sections, or obstructions that reduce airflow.

If significant ductwork work is needed, we provide a detailed estimate so you understand costs upfront. Optimizing ductwork before installation ensures your new heat pump operates at peak efficiency from day one.

We install the outdoor condenser unit on a concrete pad with proper clearance for air circulation. The outdoor unit must be accessible for service and positioned where it won’t be damaged by debris or blocked by landscaping.

We run refrigerant lines from the outdoor unit to your indoor air handler, running them through walls or crawl spaces and insulating them to prevent heat loss in winter and condensation buildup in summer. All lines are sized correctly for your system’s capacity and charged with the manufacturer’s specified refrigerant.

All electrical connections are code-compliant and sized for your system’s power requirements. We install a service disconnect switch for safety and future maintenance access.

We install the indoor air handler (the unit that distributes heated or cooled air through your ductwork) in your attic, basement, or mechanical closet. The air handler integrates with your existing furnace location if applicable, or we install it in a new location based on your home’s layout.

We connect ductwork return and supply connections, ensure condensation drains correctly (important in cooling mode), and verify all electrical connections are tight and secure. We test the system startup sequence: thermostat calls for heating or cooling, the compressor starts, and air circulates through ducts.

We charge the system to exact refrigerant specifications using professional gauges and measurements. Improper charge (too much or too little) is a common cause of heat pump inefficiency and early failure. We use superheat and subcooling methods to verify charge and document the result for future reference.

We run the system through complete heating and cooling cycles: thermostat calls for heat, the outdoor coil extracts warmth, and warm air flows through ducts. We verify outlet temperature and confirm the system reaches setpoint. We repeat for cooling mode. We test both on low and high fan speeds.

We configure your heat pump’s auxiliary (backup electric) heating to engage only when necessary—typically when outdoor temps drop below 35°F or when the heat pump alone can’t keep up with heating demand. We test this transition so you understand how your system responds to cold snaps: primary heat pump heating during mild winters; electric backup during freezing temperatures.

We explain supplemental heat operation and why it’s necessary in extreme cold, so you’re not alarmed by the backup system engaging during rare deep freezes.

With the system running, we balance airflow through your ducts to ensure even heating and cooling throughout your home. We adjust dampers and verify that every room receives adequate airflow—living rooms, bedrooms, kitchens—with no dead spots or uneven temperatures.

We program your thermostat with heating and cooling setpoints, schedule (if desired), and auxiliary heat transition temperature. We explain how to use the thermostat and how to optimize comfort and energy savings through scheduling.

We review everything: how the system switches between heating and cooling modes, when auxiliary heat engages, how to change filters, what to expect seasonally, and when to schedule maintenance. We provide all documentation—equipment specs, installation records, thermostat instructions, warranty information, and maintenance plan details.

Heat Pump Installation FAQs

Heat Pump Installation Questions Homeowners Ask

Absolutely. Heat pumps are ideal for Houston’s climate because heating needs are modest (rarely below freezing) and cooling needs are significant. A heat pump handles summer cooling as efficiently as an air conditioner and provides adequate winter heating without over-relying on expensive backup electric heat. You’ll see strong energy savings year-round.

Heat pump installation costs vary by system size, efficiency level, and ductwork needs. Compare it to replacing both a furnace and an AC unit separately—a heat pump consolidates two systems into one, which can offset some upfront cost. Over 15–20 years, operational savings through superior efficiency typically exceed the higher initial investment. Financing is available to spread the cost.

Yes. Heat pumps extract heat from outside air even on cold days. If temps drop below freezing (rare in Houston), your system includes electric auxiliary heating to ensure you’re never without warmth. Auxiliary heat is less efficient than the primary heat pump, but it’s reliable and keeps your home warm during freezes. You won’t be uncomfortable; you’ll just see a brief rise in electric usage during deep cold.

Technically you could, but it defeats the purpose. The whole advantage of a heat pump is replacing both your furnace and AC with one integrated system. Keeping an old furnace means maintaining two systems, paying for two sets of repairs, and losing the efficiency benefits of the unified heat pump. We recommend full heat pump replacement, not partial upgrade.

Usually yes, if your ductwork is in good condition. Heat pumps require well-sealed, properly insulated ducts with adequate sizing for year-round operation. We evaluate your ducts during installation. If they’re leaky or undersized, we seal or upgrade them—an investment that pays for itself through efficiency gains over a few years.

A typical heat pump installation takes 2–3 days, depending on system size and whether ductwork needs upgrades. Day one involves outdoor unit installation and refrigerant line work. Days two and three cover indoor air handler installation, electrical work, charging, testing, and balancing. We coordinate timing with you well in advance.

Ducted heat pumps use your existing ductwork to distribute heating and cooling throughout your home—best for whole-home climate control. Mini-split systems are ductless and mount on walls or ceilings in individual rooms—best for room-by-room zoning or homes without ductwork. For a fully ducted home, a ducted heat pump is more economical.

Your existing thermostat may work, but we recommend a modern smart thermostat designed for heat pump operation. Smart thermostats optimize the transition between heating and cooling modes and let you manage energy use remotely. The upgrade is typically worth the investment for comfort and savings.

Modern heat pumps are quieter than older air conditioners and furnaces. High-efficiency models from Armstrong and Samsung operate at low noise levels—you’ll hear a gentle hum when the compressor runs, but nothing disruptive. The outdoor unit is quieter than an older AC condenser.

Heat pumps need annual maintenance: refrigerant leak checks, coil cleaning, electrical connection verification, and filter changes. Regular maintenance keeps your system efficient and catches wear before it becomes a problem. We offer maintenance plans that include all routine service.

Yes. Your Armstrong or Samsung equipment carries the manufacturer’s parts warranty, and our installation work is covered by LMH Services’ 1-year labor warranty. For protection beyond the first year, we offer extended parts-and-labor plans through JB Warranties — no deductible, all brands, and transferable to a new owner at no charge. We register your equipment and provide all documentation so you know exactly what is covered.
