Styles & brands we work with







Furnace Installation
Furnace Installation is the job of putting a new gas or electric heating system into your Houston home, and it’s a decision most homeowners make once or twice in a lifetime. You need it when your current furnace is beyond reasonable repair, when repair bills start adding up to more than half the cost of a new unit, or when the old system cracks a heat exchanger and becomes unsafe to run. Cold Harbour Heating and Air Houston installs furnaces with the same written-price discipline we apply to AC work: the quote you get before the job is the price you pay when it’s done. A new furnace installation in Houston typically lands in the $3,500 – $7,500 range, depending on fuel type, efficiency rating, and whether the ductwork needs modifications. Every furnace we install carries the 365-Day Done Right Promise in writing.
When Repair Stops Making Sense
A furnace that’s 15 years old and needs a $700 fix every winter is telling you something. The math usually tips toward replacement around the 12 – 15 year mark, especially if the unit was never maintained. Victor Mancini trains our techs to be plain about this: if the repair will buy you two more years, we’ll say so. If it won’t, we’ll say that too.
Gas or Electric: Houston Reality
Most Houston homes run gas furnaces, but electric is common in newer builds and areas like Four Corners where gas lines haven’t been pulled. A gas furnace installation is often a straight swap; an electric conversion can involve a new circuit and changes to the venting. We’ll lay out both paths in the written estimate, so you can compare actual dollars before choosing.
HVAC Installation
HVAC Installation is the complete job of putting in the heating, cooling, and air-moving equipment that keeps a Houston house comfortable year-round. The term covers the full system, not just the AC unit: furnace or air handler inside, condenser outside, thermostat on the wall, and all the connecting work in between. Cold Harbour Heating and Air Houston does full-system installations with a single crew, a single written price, and a single point of contact from the first estimate through the final walkthrough. Complete HVAC Installation in Houston generally runs $3,500 – $7,500, with the spread driven by system size, efficiency level, and whether the ductwork needs help. Every installation carries the 365-Day Done Right Promise on paper before the technician leaves.
Why Do the Whole System at Once
Mixing a new condenser with a 15-year-old furnace often means the two halves don’t talk to each other properly, and you give up efficiency and warranty coverage. Replacing them together is usually cheaper in the long run than replacing one now and the other in two years. We’ll show you the difference in writing.
Matched Systems and Real Efficiency
A matched HVAC system, condenser and air handler from the same manufacturer and efficiency tier, hits its SEER rating in real-world conditions. A mismatched pair often underperforms by 15 – 20%. We install matched systems so the efficiency number on the label is the efficiency you actually get.
Heat Pump Installation
Heat Pump Installation puts in a single unit that heats and cools your Houston home by moving heat instead of burning fuel. In a city where winter rarely dips below 40°F, a heat pump is often a smarter choice than a traditional furnace-and-AC pair: one outdoor unit, one indoor air handler, one system to maintain. Cold Harbour Heating and Air Houston installs heat pumps from the brands we trust most, including Carrier and Lennox, with the same written-price rule as every other job we do. A Houston heat pump installation generally runs $3,500 – $7,500, with the exact number tied to system capacity and whether your ductwork is reuseable. The 365-Day Done Right Promise covers every heat pump we install, in writing, for a full year.
Houston’s Sweet Spot
Heat pumps are genuinely efficient in Houston’s mild winters, unlike the northern freeze-out zones where they struggle. Modern cold-climate heat pumps operate efficiently down into the teens, which covers anything Houston’s weather throws at them. For homes in La Porte or Alvin near the water, where heating demand is modest, a heat pump can cut winter energy use meaningfully.
Ductwork Still Decides the Price
The heat pump itself is only part of the quote. If your ductwork leaks or was sized for an old furnace, the airflow won’t support an efficient heat pump. We inspect the ductwork before we write a price, so the number on the page is the number that holds.
Ductless Mini Split Installation
Ductless Mini Split Installation adds a wall-mounted indoor unit connected to an outdoor condenser, giving you zoned heating and cooling without running any ductwork. You need one when you’re building out a garage apartment, converting a sunroom, or cooling a room that never quite gets there from the central system. In Houston’s humid climate, mini splits also pull a surprising amount of moisture out of the air, which is why we’re installing more of them in Gulf-facing communities like Dickinson and our AC Installation in Channelview. A ductless mini split installation in Houston typically runs $3,500 – $7,500 depending on the number of indoor heads and the line-set distance. Cold Harbour Heating and Air Houston stands behind every mini split with the same 365-Day Done Right Promise, written down before the technician leaves.
Zoning Without Ductwork
Ductless systems don’t force you to cool or heat rooms you’re not using. Each indoor head runs its own thermostat, so a bedroom in Missouri City can stay cooler at night while the living room idles. That’s efficiency you can feel in the electric bill.
Matching Capacity to the Room, Not the House
An oversized mini split short-cycles and an undersized one never catches up. We size each head to the room it serves, factoring in Houston’s humidity load, window exposure, and how the room is actually used. The written estimate shows the model, the capacity, and the labor, so you know exactly what you’re paying for.
AC Replacement
AC Replacement means removing a failing condenser or a worn-out air handler and installing new equipment in its place, usually reusing the existing ductwork and electrical service. You’re in replacement territory when the compressor has seized, the coil has a leak that braze won’t hold, or the system is old enough that a major repair is throwing good money after bad. Cold Harbour Heating and Air Houston does AC replacement in Houston as a one-day job in most cases, with a written price in your hand before the old unit comes off the pad. A typical Houston AC replacement runs $3,500 – $7,500, and the range is set by efficiency tier, brand, and any duct or electrical upgrades the job requires. Every replacement carries the 365-Day Done Right Promise: if the new system has an issue inside a year, we come back and make it right at no charge.
Compressor Failure Is the Tipping Point
When the compressor goes on a 10+ year old unit, the repair bill can run $1,500 – $2,500, and you’re still cooling with an aging system. At that point, replacing the condenser and matching the indoor coil usually pencils out. We’ll walk you through the repair-versus-replace math with actual Houston pricing, not scare tactics.
Reuse the Ductwork, Replace the Core
Most Houston homes have usable ductwork that doesn’t need replacement when the AC goes. We inspect, we measure airflow, and we only recommend duct replacement when it’s genuinely leaking or sized wrong. Every recommendation is in writing before any work starts.
Central Air Conditioning Installation
Central Air Conditioning Installation is the full job of putting in a split-system AC for a standalone Houston home: an outdoor condenser, an indoor evaporator coil, a blower, and the thermostat that ties them together. It’s the right call when you’re building new, when a window unit can’t keep a three-bedroom brick ranch in Aldine below 80°F, or when the existing system is simply done. Cold Harbour Heating and Air Houston installs central air in Houston with technicians trained on nine major residential brands, and we give you the written price before the first tool comes out. Central AC installation in Houston typically lands between $3,500 and $7,500, with the specific number driven by system tonnage, SEER rating, and site conditions. The 365-Day Done Right Promise goes with every system we put in, on paper.
Sizing for Houston’s Heat and Humidity
A central AC that’s oversized cools fast but never runs long enough to strip the humidity out of the air, which leaves a cold, clammy house. Undersized means the unit never reaches set point in August. We do a load calculation on every installation, not a guess from the old unit’s nameplate.
Removal and Cleanup Are Part of the Price
We haul away the old condenser and coil, and we leave the work area cleaner than we found it. That’s part of the written quote, not an optional add-on. You shouldn’t have to haul a dead AC to the curb yourself.
Brands We Service
Carrier units are the most common systems we install in West University Place and the Heights, and our techs have worked on hundreds of them across Houston. We stock Carrier OEM parts on the truck, which means a failed capacitor or contactor doesn’t turn into a two-day wait for a part to ship. If you already run a Carrier, we’ll keep it running, and when it’s time to replace, we’ll install a matched Carrier system sized to your home.
Trane systems are built like tanks, but like any tank they need the right maintenance and the right repair parts when something breaks. We carry Trane-specific diagnostic experience on every truck, and our techs know the common failure points on Trane’s scroll compressors and variable-speed air handlers. Lennox and Goodman units round out the brands we see most often in League City and South Houston, and the same rule applies across all of them: if it’s in your home, we service it, and our written guarantee covers the work regardless of brand. Whether you have a Carrier, Trane, Lennox, Goodman, or any other make, we can help.

- Warm air blowing from the registers. If your AC is running but the air coming out is warmer than the room, the compressor may have failed or the refrigerant charge is low. On a 95°F Houston afternoon, that’s a real health risk for older adults and small children. Call us and we’ll get a technician out to diagnose it.
- Ice on the refrigerant lines or the indoor coil. Ice on an AC means airflow has dropped or the refrigerant charge is wrong, and running it like that can destroy the compressor. This is the most common preventable failure we see in Houston, and it usually starts small. Shut the system off and call us before it becomes a $3,500 replacement.
- Water pooling around the indoor unit. A clogged condensate drain in a Houston attic can drip through the ceiling and cause real damage. If you see water, the drain is already backed up. We’ll clear it and check the float switch so it doesn’t happen again.
- The system runs constantly but the house never cools down. That’s often a sign the system is undersized for the heat load, or the ductwork is leaking cooled air into the attic. Both problems need a real diagnosis, not another thermostat adjustment. We’ll measure airflow and temperature drop to find the actual cause.
- Burning smell or electrical odor from the unit. A burnt smell can mean a failing capacitor, seized blower motor, or arcing electrical connection. Turn the system off at the breaker and call us. This is a fire hazard, not a filter problem.
Our Process, Step by Step
- 1
Call us, talk to a person. When you call (832) 371-9862, a live person answers, day or night. We take your information, ask a few questions about what the system is doing, and give you a firm arrival window, not “sometime between 8 and 8.”
- 2
We show up in that window and inspect. The technician arrives in uniform, checks in with you, and does a full inspection: condenser condition, coil, airflow, duct runs, electrical, and thermostat. We measure, we don’t guess, and we explain what we find in plain language.
- 3
You get a written price before any work starts. This is The Kingswell Way, the standard Cold Harbour has followed since 2003. The price on the paper is the price you pay. No surprise line items, no door-knock repricing. You approve it in writing before a single tool comes off the truck.
- 4
The work is done, tested, and cleaned up. We install the system, pull a proper vacuum on the lineset, check the charge, and test the unit in heating and cooling. We leave the work area cleaner than we found it, and we haul away the old equipment. You get a walkthrough of the new system before we leave.
- 5
Your 365-Day Done Right Promise comes in writing. Before we leave, we hand you the written guarantee that covers the installation for a full year. If anything fails inside 365 days, we return and correct it at no charge. No argument, no fine print, just a promise on paper.
How Much Does AC Installation Cost in Houston?
Typical AC Installation pricing in Houston runs $3,500 – $7,500. On the lower end, you’re looking at a straight-swap Goodman or Rheem system in a smaller home with good ductwork. On the upper end, a high-SEER Carrier or Trane system in a larger house, or a job that requires duct modifications or new electrical, pushes toward the top of the range. The main factors that move the number: system tonnage, efficiency rating (SEER2), brand, and the condition of your ductwork and electrical. A house in Missouri City with a long lineset run or a closet air handler that needs a platform will cost more on labor than a simple garage-installed system in Aldine. You avoid overpaying by getting a written quote that breaks out equipment, labor, and any duct or electrical work separately, and by insisting on a matched system rather than a mismatched condenser-and-coil set. Our free estimate includes all of this: a full inspection, a written price, and an explanation of what each line item covers. Call (832) 371-9862 and we’ll schedule it, usually within a day.

Frequently Asked Questions About AC Installation in Houston
AC Installation is the process of putting a new air conditioning system into your Houston home, including the outdoor condenser, indoor coil or air handler, refrigerant lines, and thermostat. The work starts with a load calculation to size the system correctly for your home’s square footage and Houston’s heat load, not just swapping in whatever was there before. Our installations are covered by the 365-Day Done Right Promise, so if something fails inside a year, we return and fix it at no charge.
Most Houston AC installations take one full day, usually 6 – 8 hours from arrival to final testing. Jobs that require significant ductwork replacement, new electrical circuits, or a crane lift for a rooftop unit can run into a second day. We’ll tell you the expected timeline in writing before the work begins.
Central AC installation in Houston runs $3,500 – $7,500. The final number depends on system size (tonnage), efficiency (SEER2 rating), brand, and whether the existing ductwork and electrical can be reused. Every quote we give is a written, line-item price you approve before any work starts. Call (832) 371-9862 for a free estimate and we’ll show you the exact number for your home.
Yes, we install and service Carrier systems across Houston, and we stock Carrier OEM parts on our trucks. Our technicians are also trained on Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. Whatever brand is already in your home, the technician who shows up knows how to work on it.
A live person answers the phone at (832) 371-9862 24 hours a day, 7 days a week. If your AC dies on a July night in Houston, you’ll talk to a human, not a voicemail tree. We prioritize calls where the home has small children, elderly residents, or medical conditions that make extreme heat dangerous.
Every installation carries the 365-Day Done Right Promise in writing. If the system fails within a full year of installation, we come back and correct the work at no charge. This is not a verbal promise. It’s a written guarantee, on paper, handed to you before the technician leaves. Manufacturer warranties on the equipment itself run separately and we register them for you.
Clear a path to the indoor unit and the outdoor condenser pad, and make sure the electrical panel is accessible. Move any furniture or stored items that block access to the air handler or the attic hatch if the unit is up there. We’ll give you a short checklist when you book the job, and the technician will walk through everything on arrival day.
