Size It to the House, Not to the Old Unit
The most common installation mistake is matching the new system to the old nameplate. Houses change. Windows get replaced, attics get blown in with insulation, a garage becomes a bedroom, and the old unit may have been wrong from the start. A system that is too big cools quickly, shuts off, and leaves the air damp and clammy. One that is too small runs all afternoon and never catches up.
People ask whether a three ton unit can cool a two thousand square foot house. Sometimes, in a well insulated house with shade. In a Mission summer, with a west facing wall and an older attic, the same house may want three and a half or four tons. The right answer comes from a load calculation on your actual house, and we explain the number we land on and why.
What We Check in Mission Homes Before Quoting
Mission has a wide mix of housing, from older homes near downtown and Conway Avenue to newer builds toward Sharyland and the north side. The ductwork is where they differ most. In older houses the ducts are often undersized for a modern system, leaky, or crushed in the attic. A high efficiency unit connected to bad ducts delivers the efficiency of a low one.
- Duct condition, size and leaks, since the ducts decide whether the new unit performs.
- Attic insulation and how hot the attic gets, which sets a lot of the cooling load.
- Window orientation and shade on the west and south sides.
- The electrical service and disconnect, which sometimes need updating on older homes.
- Where the drain line goes, so humidity does not end up in the wrong place.
Winter Texans and Second Homes
If your Mission house is empty half the year, the system gets fewer running hours, so a unit can last longer than the usual ten to fifteen years the Valley's constant summer runtime allows. It also means a problem can sit unnoticed for months. Ask for a startup test after installation, and plan a quick check the first time you return each season.
Newer systems also use refrigerants with a lower global warming impact, such as R-454B, as federal rules replace R-410A in new equipment. Existing R-410A systems can still be serviced. If you are choosing between repairing an older unit and buying new, ask which refrigerant each option uses and what a future repair would involve.

"Carlos came on a Friday, gave us a quote and said he could install the next day. Arrived on the scheduled time and 45 minutes later we had A/C, for the quoted price. I had some other people do some work for us and the final price was well above the quoted price."
Michael Gavin
"Our home system was over 10 years old and giving out every 6 months. It was time to replace it; Carlos and his son came over and replaced our HVAC system, very nice and knowledgeable."
Anthony Gonzalez
"After 11 months my two new HVAC units are still running perfectly and I am saving about 30% off of my monthly electric bill so they'll pay for themselves in about three or four years."

Mission AC Installation FAQs
How do I know what size AC my Mission home needs?
Square footage alone is not enough. Insulation, windows, ceiling height, shade and duct condition all change the load. We calculate it for your house and explain the result.
Will a 3 ton AC cool a 2,000 square foot house?
It can in a tight, shaded, well insulated house. In the Valley's heat, many two thousand square foot homes need more. A load calculation settles it, so do not buy on a rule of thumb.
How long does an air conditioner last in the Valley?
Plan on ten to fifteen years. Constant summer runtime shortens life compared with cooler regions, and clean filters, a clear drain line and annual checks stretch it.
Do I need to replace the ductwork with the new unit?
Not always. We inspect the ducts before quoting. If they are sound, we connect to them. If they are leaking or undersized, we say so, because they limit how well any new unit can perform.
What does the installation warranty cover?
One year on labor and ten years on parts for new installations. Ask for the equipment manufacturer's warranty paperwork too, and keep both with your records.
What payment methods do you take?
Cards, cash, Zelle, Cash App, PayPal and checks. Ask when you get your quote and we will explain how payment works for your job.
