Downstairs cold, upstairs hot is the classic Cypress complaint, and it usually has a fix short of a new system. Call any time and you will be put through to a licensed local AC company.
Call 832-662-4107Cypress is full of two-story houses, and the most common complaint from them is the same: downstairs is cold, upstairs is not, and turning the thermostat down just makes downstairs colder. Heat rises, the upstairs sits right under a hot attic, and a single system with one thermostat downstairs has no way to know the bedrooms are suffering.
There are real fixes, and a good technician will say which one fits your house:
| What is going on | What usually fixes it |
|---|---|
| Too few or too small return vents upstairs | Adding return air so the rooms can actually exchange air |
| Supply ducts upstairs undersized or leaking in the attic | Resizing, sealing or reconnecting the duct runs |
| One system, one thermostat, two very different floors | A zoning system with a second thermostat and dampers |
| A large house on a single undersized system | A second, separate system for the upstairs |
Start with the cheap end. Many upstairs problems are airflow, not capacity.
Bridgeland, Towne Lake and the subdivisions along US-290 and the Grand Parkway have thousands of homes with systems only a few years old. If yours fails young, find the paperwork before paying for a repair:
Cypress is unincorporated Harris County, so no city mechanical permit or inspector is involved in an AC replacement. What does apply is the state license: anyone contracting to repair or install air conditioning in Texas needs an Air Conditioning and Refrigeration Contractor license from TDLR, which you can confirm on the TDLR license search.
A long Houston summer finds every weak part. Failed capacitors and contactors are the most frequent call, followed by frozen coils from clogged filters and condensate lines that back up in the humidity. Hurricane Beryl in July 2024 added another: systems that would not restart properly after days without power. For more, see AC not cooling, tune-ups and the free refrigerant change guide.
Usually airflow: too little return air upstairs, undersized or leaking attic ducts, or one thermostat trying to control two floors. Zoning or a second system fixes the harder cases.
Check the builder's warranty and whether the equipment was registered for the manufacturer's extended parts warranty. An early leak or drain problem is often an installation fault.
There is no city permit, because Cypress is unincorporated. The contractor still needs a Texas Air Conditioning and Refrigeration Contractor license from TDLR.
In a two-story house with a single system, often yes, once the ducts and return air are right. It lets each floor call for cooling on its own.
