Real Texas Plumbing - Heating and Air is a family-owned HVAC and plumbing company based at 20811 Dawn Drive in Lago Vista, Texas, with a second location in Lakeway. We replace and install central air conditioners, heat pumps, and ductless mini-split systems for homeowners in Lago Vista, Jonestown, The Hollows, Point Venture, Lakeway, and the surrounding Lake Travis communities. If your AC is on its way out, we will tell you straight whether a repair or a replacement is the smarter spend - and put written numbers for both in front of you before any work starts.
Replace your AC when it is 12 to 15 years old or older, when a repair would cost more than about a third of a new system, or when breakdowns and rising bills have become the pattern. A rule of thumb we share with every customer: multiply the unit's age by the repair quote - if the result tops $5,000, replacement is usually the smarter spend.
Signs it is time to start pricing a replacement:
The system is 12+ years old. Central Texas cooling season runs roughly April into October, so units here log far more hours than national lifespan averages assume.
Repairs are getting bigger and closer together.
Your summer electric bills keep climbing even with the same thermostat habits.
Some rooms never cool down, or the house feels sticky even when it is cool. That is often a duct problem, not an AC problem. We check the ducts before we recommend a bigger system. See air duct repair.
The unit still runs on R-22 (fully phased out) or older R-410A - refrigerant for these systems gets more expensive every year.
Not sure which side you are on? We will quote the repair and the replacement side by side and let you decide. No pressure either way - if a $300 fix buys your system three more good years, we will tell you so. AC Repair in Lago Vista.
Most full system replacements in the Lago Vista area run between $6,500 and $18,000 installed, depending on the size of your home, the efficiency tier you choose, and the condition of your ductwork and electrical. You get an exact written price before we order equipment - the number on the estimate is the number on the invoice.
What moves the price up or down:
System size (tonnage) - set by a load calculation of your actual house, not by copying the old unit's label.
Efficiency rating (SEER2) - higher efficiency costs more upfront and less every month on your electric bill.
System type - straight-cool AC with a furnace, a heat pump, or ductless mini-splits.
Ductwork and airflow - leaky or undersized ducts can rob a new system of a third of its capacity; sometimes they need sealing or repair.
Electrical and code items - disconnects, breakers, pads, and line sets that have to be brought up to current code.
Refrigerant lines and the indoor coil - matched components protect efficiency and the manufacturer warranty.
A proper replacement is more than swapping boxes. Every Real Texas AC replacement includes:
A load calculation of your actual home - square footage, windows, insulation, sun exposure - so the new system is sized right, not just sized the same as the old one. Oversized units short-cycle and leave the house humid; undersized units never catch up in August.
Removal and haul-away of the old equipment.
Installation of the new condenser, indoor coil, and matched components to code and manufacturer specifications.
Refrigerant charge and airflow dialed in and verified - not eyeballed.
Thermostat setup and compatibility check.
A full startup test: refrigerant pressures, temperature split, drain lines, electrical, and overall performance.
A walkthrough of the finished work, warranty registration, and a clean job site.
In-home evaluation and same-visit estimate. A technician inspects your current system, airflow, and thermostat, measures the house, and talks through your comfort complaints. In most cases you get a written estimate before we leave.
Removal and installation. Once you approve, we protect your floors, pull the old unit, and install the new system to code and manufacturer standards. [VERIFY: if most single-system swaps are done in one day, say exactly that - it is one of the most-searched questions.]
Startup, testing, and walkthrough. We test refrigerant levels, airflow, thermostat operation, and drains, then walk you through the system and leave the work area clean.
All three cool a Texas home the same way - the difference is how they heat and where they fit. A heat pump is a central system that also runs in reverse to heat your home efficiently through our mild Hill Country winters, usually for less than electric resistance heat. A ductless mini-split cools and heats without ductwork, which makes it the right answer for additions, garages, workshops, and casitas. We install and service all three, and we will price the options against your house and your bills instead of pushing the biggest ticket. (Links: Ductless Mini-Splits · Heating Replacement.)
Two rules changed recently that shape every replacement quote you will get. First, new systems installed in Texas must meet at least 14.3 SEER2, the federal efficiency minimum for the South region. Second, since January 2025 new equipment ships with next-generation refrigerants like R-454B instead of R-410A. Both changes are good news long term - lower bills and equipment that will not be orphaned by a refrigerant phase-out - but they are also why quotes are higher than they were a few years ago. We will show you what each efficiency tier actually saves on your electric bill before you pick one.
One more local note: most Lago Vista and Jonestown homes get their power from Pedernales Electric Cooperative (PEC), which has offered rebates for qualifying high-efficiency HVAC upgrades. Ask us to check the current program when we quote your system.
Cooling season on this side of Lake Travis runs roughly April into October, with long stretches over 100 degrees - an AC here can log half again more runtime hours per year than the same unit would up north. That is why sizing, airflow, and install quality matter more in Lago Vista, not less: a system that is merely adequate in May falls apart in August.
