A Greater Houston heat pump quote is a stack of decisions wearing a single number, and this guide unstacks it. The bands run from a few thousand dollars for a single-zone ductless unit in a Heights bungalow to the deep five figures for a whole-home conversion in River Oaks, and the spread between honest quotes for the same house is usually explained by scope rather than greed. What follows are the bands, the variables that move a project between them, where the CenterPoint money fits, and the discipline that keeps a five-figure decision from being graded by the first saturated August it was never sized for, in the metro where August lasts half the year.
The Bands
| Project type | Typical Greater Houston range |
|---|---|
| Single-zone ductless | $3,500 to $7,000 |
| Multi-zone ductless, two to four heads | $8,000 to $16,500 |
| Ducted changeout, usable ducts | $7,000 to $14,000 |
| Whole-home conversion, new or heavy ductwork | $13,000 to $25,000 |
| Dual fuel, heat pump plus gas furnace | $10,500 to $20,000 |
The bands are wide because the houses are. A Katy two-story with clean trunks sits at the bottom of the changeout band; a Montrose four-square asking for three heads and careful routing sits high in the multi-zone band for reasons a site visit makes obvious. Treat any figure quoted before a measurement as a genre of fiction.
What the Climate Charges For
Houston's design nights sit around the low thirties, mild enough that most quality variable-speed machines pass the capacity test in our cold-weather guide without any cold-climate premium, which widens the qualifying field and sharpens competition. What the climate charges for is the summer: the longest, wettest cooling season in the region, where dehumidification at part load is most of the job description and equipment works harder, longer, than almost anywhere in the country. The winter's contribution is the occasional Arctic front that reaches the coast, a few hard nights a decade that punish lazy backup staging with strip-heat bills and that this metro remembers well enough to specify against.
The Most Common Trigger: The Compressor Dies in August
Greater Houston buys most of its heat pumps under duress, in summer, when the old air conditioner quits during a heat advisory. That timing is exactly why the specification discipline matters. The replacement dollar was being spent anyway; the only question is whether it buys a cooling-only machine plus another decade of the old heating arrangement, or one variable-speed system that handles both seasons. The panic purchase copies the old tonnage and regrets it for fifteen years, because oversizing ruins dehumidification, and in this metro dehumidification is the product. The measured purchase takes one extra afternoon and gets the humidity right.
Ducts, Measured Before Sized
The master-planned rings, Katy, Sugar Land, Pearland, Cypress TX, The Woodlands, mostly carry reusable trunks, but builder-grade ducts sized to a construction budget can choke a heat pump's steadier airflow, and in this climate undersized returns complain loudest in the wet months. Much of the metro's ductwork also runs through attics that spend half the year at oven temperatures, where duct sealing and insulation pay their way twice. A static-pressure reading before sizing costs little and prevents the region's most common comfort complaint. In the older inner-loop stock, The Heights, Montrose, Garden Oaks, where usable ducts thin out, the cost driver becomes head placement and line-set routing, decided by someone who can point to work in houses like yours.
The Panel Question
The older stock, The Heights, Montrose, and the prewar streets around the Museum District and Third Ward, often runs older electrical service, and a whole-home conversion can force new circuits or a service upgrade with coordination and lead time attached. Panel work runs roughly $1,500 to $4,000 when needed, and the honest bidder opens the panel at the site visit and prices what they find. The evasive one discovers it after signing, as a change order. Ask in the first call: what will you check on my panel, and will any panel work be itemized?
Drainage, Flood Wisdom, and Placement
Houston's flood history has taught its trades a placement discipline worth demanding. Outdoor units in flood-prone sections belong above known water lines, on raised pads or brackets, priced as a named line rather than improvised. Condensate handling deserves equal attention: a machine that runs dehumidification for seven months produces water in volumes northern installers never see, and a clogged or badly pitched drain line is this region's quietest recurring service call. Both answers belong in writing before a price does.
Where the Rebate Fits
CenterPoint Energy's Standard Offer Program pays up to $500 per unit for a qualifying heat pump, delivered through participating contractors rather than homeowner applications, which folds the rebate question into contractor selection itself, per our CenterPoint guide. The correct position for the money is last: price the project to stand on its own numbers, confirm the contractor's participating status and the machine's qualifying tier in writing, and let the incentive appear as a named line. A bid citing the federal credits that ended December 31, 2025 is stale on its face.
The Cheaper Levers First
Two line items routinely outperform an extra ton of capacity per dollar. Air sealing and attic insulation shrink the load the machine must cover, and in a metro where the attic is the hottest room in the house for half the year, insulation is the rare purchase that improves both seasons at once. A contractor who suggests envelope work before upsizing equipment is optimizing your money; one who solves every load with tonnage is optimizing their invoice.
Operating Cost, the Second Price
The purchase price is the number on the quote; the operating price arrives monthly for fifteen years, and in Greater Houston it is mostly a cooling bill. A right-sized variable-speed machine undercuts the old single-stage air conditioner through the long season and replaces strip heat or shrinks a gas bill in the short one, which is the arithmetic in our fuel comparison. The sizing keeps the operating price honest: oversized cooling short-cycles and leaves the house clammy through the longest season on the calendar, and that mistake is this region's signature error.
Three Quotes, Read Correctly
Collect three bids and expect the market to sort itself. One arrives fast, low, and paperless; it has skipped the load calculation and its price is an estimate of your patience. One arrives high and thorough; make it justify its scope line by line, which a good contractor does without flinching. The signable bid usually produced documents before being asked: a room-by-room load calculation with the humidity term carried, published capacity at the design condition, participating-contractor status stated, duct and panel findings recorded, R-454B equipment specified. The vetting sequence lives in our contractor guide. Price matters, but only between bids that passed.
The Short Version
Single-zone ductless from about $3,500; whole-home conversions to the mid twenties; the inner loop pays a routing premium, the master-planned rings pay for duct corrections when the measurement demands them, and flood-wise placement plus serious condensate handling are named lines here, not afterthoughts. CenterPoint's $500 arrives through participating contractors and gets confirmed, not assumed. The climate charges almost everything for summer. Spend the extra afternoon on the load calculation; it is the cheapest component in the entire project.
