AC installation

Straight answers

Questions East Texas homeowners ask us

In Tyler's climate, annual AC service before summer is the minimum, ideally every spring. East Texas heat and humidity run systems harder and longer than most U.S. regions, so a pre-season tune-up catches refrigerant issues, dirty coils, and worn parts before peak demand hits.

Warm air blowing from vents, weak airflow, unexplained spikes in your electric bill, or grinding or squealing noises are all repair indicators. A system cycling on and off frequently can also signal a failing thermostat or compressor, issues that worsen quickly in East Texas summers.

If your heating system is over 15 years old and repair costs exceed half the price of a new unit, replacement typically makes more financial sense. Frequent breakdowns, uneven heat distribution, or rising utility bills despite normal use are also strong signals that a new installation is the better investment.

Whole-home generator installation includes sizing the unit to your electrical load, connecting it to a natural gas or propane line, installing an automatic transfer switch, and completing code-required inspections. Once installed, it powers on automatically during an outage, no manual startup or extension cords required.

Standby generators should receive professional service at least once a year, typically covering oil and filter changes, battery checks, transfer switch testing, and load bank testing. Regular maintenance keeps the unit ready to perform when it's needed most and extends overall equipment lifespan.

Yes. TDI Air Conditioning provides prompt, same-day AC repair service across Tyler and the surrounding East Texas area, including Longview, Bullard, Jacksonville, Athens, and Lindale. Technicians diagnose the problem on-site and give honest repair-vs-replace guidance before any work begins.
