We diagnose before we quote
Warm air at the vents can be a twenty dollar part or a failed compressor. Those look identical from inside the house, so we test the system rather than guessing from the symptom you describe on the phone.
Home/About
Residential heating and air conditioning for the Dallas–Fort Worth area. A small operation built around answering the phone, explaining the problem, and charging what the work is actually worth.
When you call Manuel Guerrero HVAC, you are not entering a queue. The person who answers the phone is the person who works on the equipment, and that single fact shapes everything about how a service call goes.
There is no dispatcher reading from a script, no commissioned salesperson showing up in place of a technician, and no reason to condemn a system that still has good years left in it. You get a diagnosis, a written price, and a straight answer about whether repairing or replacing is the better use of your money.
That is a smaller way to run an HVAC company than most. It also means the work happens in the same county where our customers live, and word of mouth here is the only marketing that has ever really mattered.
Four things that hold true on every call, whether it is a capacitor in July or a full system in October.

Nothing gets repaired before you have heard what it costs and said yes. No work order gets padded after the fact, and no line item shows up that you did not agree to.
Replacement is a recommendation we make when the numbers support it, not a default. On an older system you get both figures side by side and you decide which one makes sense.
A replacement gets a load calculation, not a glance at the tonnage stamped on the old unit. Oversized systems cool fast, shut off before pulling humidity out, and wear their compressors out early.
Residential heating and cooling, start to finish.
Systems blowing warm, running constantly, or not starting at all.
Gas furnaces, heat pumps, and electric heat.

Spring cooling checks and fall heating checks.
Filtration, duct sealing, and humidity control.
