Kinsey Plumbing, Heating & Air replaces and installs complete HVAC systems in Liberty Hill, putting in new cooling equipment, heating equipment, ductwork connections, and controls as one matched system built for your home. When both halves of your comfort system are worn out, replacing them together usually gives you better performance, efficiency, and warranty coverage than patching one piece at a time.
Call us if your air conditioner and furnace or heat pump are both well over a decade old, you have paid for major repairs on both sides in the last few years, the house never feels evenly comfortable in summer or winter, energy costs have crept up year after year, your equipment uses a phased out refrigerant, the ducts are leaky, crushed, or poorly laid out, or you are planning a remodel or addition that changes how the home is heated and cooled.
Licensed Kinsey technicians manage full system projects from our shop in Jarrell, beginning with a free estimate and a fixed price you approve before any equipment comes out. Our warranties on the work reach past the industry standard.

Replacing an entire HVAC system is the right time to fix problems that have bothered you for years, such as rooms that never balance, high humidity, or noisy airflow. We start with a whole-home evaluation: square footage, insulation, window exposure, attic conditions, and the layout and condition of the ductwork. A load calculation tells us exactly how much heating and cooling capacity the house needs, and from there we design a matched system rather than simply copying the size of whatever was there before.
You receive a free written estimate with options at different efficiency levels, including air conditioner and furnace combinations, heat pump systems, and add-ons like zoning or improved air filtration. The installation price is flat and does not change once you approve it. If part of your existing system is still in good shape, we tell you, and we never pressure you into more than the house needs.
Our crew handles the full project: removing old equipment, installing the new outdoor and indoor units, repairing or modifying ductwork, sealing connections, setting up the thermostat, and testing airflow, refrigerant charge, and heating operation before we leave. The same lead technician follows the project from estimate to final walkthrough and stays your contact afterward.
Homes around here place real demands on a full system. Central Texas summers push past 100 degrees for weeks at a time, winters bring short but sharp freezes, and the equipment has to handle both. Newer master-planned subdivisions often have modern duct designs that pair easily with new equipment, while older houses on acreage may need duct repairs or redesign before a new system can perform as rated. We address those conditions in the plan rather than leaving them for later.
Our full HVAC system services include:
A properly designed and installed system delivers even temperatures from room to room, controls humidity in summer, provides steady warmth in winter, and runs quietly with less energy than worn equipment. Because the indoor and outdoor components are matched, they work together efficiently and are covered under a single set of warranties. You also start fresh with a known service history and a clear maintenance plan.
Putting off a full replacement often means spending more for less. Older systems lose efficiency each year, and repairing one side of the system while the other side is failing can leave you paying for two breakdowns instead of one upgrade. A complete failure in peak summer or a hard freeze can also leave you without heating or cooling while you wait for equipment.
When the work is complete, we walk you through the new equipment, thermostat controls, filter schedule, and warranty details. We also set you up with a maintenance plan option so the system keeps performing like new, with the final decision left to you.
Many homeowners time a full replacement for spring or fall, when the weather is mild and the house can go a day without heating or cooling comfortably. Planning ahead also gives you time to compare options, review efficiency ratings, and schedule installation on your terms rather than in an emergency.
When your furnace and air conditioner have reached the end of the road, ask us for a free estimate and we will plan a system built around your home.
