An undersized AC runs all afternoon in August and still can’t keep up. An oversized one cools fast but leaves the house damp. Gelid Tech helps you choose an air conditioner sized for your home, installs it, and checks that it cools properly before we leave.
Signs It’s Time for a New AC
- Your system is 12 to 15 years old or more
- It uses R-22 refrigerant, which is no longer produced in the US
- It needs a repair every summer
- Your electric bills keep climbing
- Some rooms never reach the set temperature
How We Install Your Air Conditioner
- Sizing. We look at your home’s square footage, insulation, windows and sun exposure instead of copying the old unit’s size.
- Choosing a system. We explain efficiency ratings, single-stage and variable-speed options, and what each costs to run.
- Installation. We remove the old equipment, set the new outdoor and indoor units, and connect refrigerant lines, wiring and drains.
- Startup and testing. We check refrigerant charge, airflow and temperature drop, then show you how to use the thermostat.
What a New AC Changes
A correctly sized, modern system cools more evenly, removes more humidity and uses less electricity than a 15-year-old unit. In a climate where the AC runs five months a year, that difference shows up on every bill.
Paying for a New System
A new AC is a large purchase. Ask about our HVAC financing options to spread the cost over time.
After Installation
Protect your new system with yearly HVAC maintenance. If you also need heat, we can quote a matching furnace installation so both systems work together.
Types of Air Conditioning Systems We Install
- Central split systems: the most common setup in Mansfield homes, with an outdoor condenser and an indoor coil paired with your furnace or air handler.
- Heat pumps: they cool in summer and heat in winter with one outdoor unit. In a mild North Texas winter, a heat pump can replace both the AC and much of the furnace’s work.
- Two-stage and variable-speed systems: these run at lower speeds most of the time, so they hold a steadier temperature, remove more humidity and run more quietly than single-stage units.
- Ductless mini-splits: a good fit for a garage conversion, a room addition or a space the ductwork doesn’t reach.
Understanding SEER2 Efficiency Ratings
SEER2 measures how much cooling a system delivers for the electricity it uses. A higher number means lower running costs. Since 2023, new systems are rated under SEER2, and the federal minimum in Texas and other southern states is higher than in northern states. Compared with a 15-year-old system, a modern unit can noticeably reduce summer bills. The right rating for you depends on your budget, how long you plan to stay in the home, and how hard your AC works each summer.
Why Correct Sizing Matters
Many older Texas homes have air conditioners that were sized by guesswork. An oversized unit cools the air quickly but shuts off before it removes humidity, leaving the house cool and clammy. It also turns on and off more often, which wears parts faster. An undersized unit runs nonstop on hot afternoons and still can’t keep up.
We size your new system using a load calculation that looks at square footage, insulation, window size and direction, ceiling height, duct condition and the number of people in the home. That is how you get even temperatures in every room.
Your Ductwork Matters Too
A new AC can only cool as well as the ducts that carry its air. Leaky, crushed or undersized ducts waste cooling in the attic and leave far rooms warm. During your estimate, we look at the ductwork and the return air path and tell you if anything needs attention before the new system goes in.
Thermostats and Indoor Air
A new system is a good time to upgrade the thermostat. Programmable and smart thermostats let you set the house warmer while you’re away and cool it before you get home. If anyone in your home has allergies, ask about better air filtration at the same time.
What to Expect on Installation Day
We protect your floors, shut off power and refrigerant, and remove the old equipment. The new outdoor unit is set on a level pad, the indoor coil is matched to your furnace or air handler, and the refrigerant lines are brazed, pressure tested and evacuated before the system is charged. We finish by testing airflow and cooling performance, cleaning up, and showing you how to use your thermostat. Most replacements are complete in one day.
AC Installation FAQ
How long does AC installation take? Most replacements of an existing system take one day.
What size AC do I need? It depends on more than square footage. Insulation, windows, ceiling height and sun exposure all matter, so we measure before recommending a size.
Should I repair or replace my AC? If your system is under 10 years old with one failed part, AC repair usually makes more sense.
How long does a new air conditioner last? In North Texas, where systems run hard every summer, many central air conditioners last 12 to 15 years with regular maintenance.
Do I need to replace my indoor coil too? Usually, yes. The indoor coil and outdoor unit are designed to work as a matched pair, and older coils are often not compatible with today’s refrigerants.
Can I replace just the outdoor unit? Sometimes, but mismatched equipment often runs less efficiently and can affect the warranty. We will explain the options for your system.
What should I do to prepare for installation day? Clear a path to your indoor unit and outdoor unit, and make sure someone is home to let the crew in and approve the final setup.
