Denton County asks a lot from both sides of the system
Your system works most of the year here. Cooling runs May through October, six months, with afternoons that average 94°F. Heat runs November through March, five months, on nights that average 36°F. Only one month gives the system a break.
More than half the homes in the area heat with electricity, so when the power goes out, the furnace or heat pump goes with it. Statewide, a third of households lost power for at least 24 hours in 2024, and this area has logged 20 winter storms and 115 damaging wind events over the past ten years. A new system installed here should be sized for a 36°F night and a 94°F afternoon, and it should be installed by someone who knows what the local storms do to a power supply.

Texas requires HVAC contractors to hold a state license.
The Texas Department of Licensing and Regulation tests HVAC contractors before it issues a license, and it keeps a record of who holds one. That license belongs to the contractor, not to any single job, so it tells you the person or company on your property has met the state's standard, not that this particular installation was checked.
That checking happens at the local level. In most cities and counties, putting in a new furnace, air conditioner or heat pump needs a permit from the local building office, and the work gets inspected once it is done. The license tells you who is allowed to do the job. The permit and inspection tell you whether this installation was done right.

- When should I replace my HVAC system?
- Once your system needs repairs almost every year, or a repair costs a large share of what a new system would run, replacement makes more sense than keeping it going. An older furnace or air conditioner works harder just to keep up, and parts get harder to find as it ages. With homes here needing heat or cooling 11 months of the year, a system on its last legs does not get much rest to recover between seasons. If you are unsure whether yours is worth fixing again, a contractor can look at its condition and give you a straight answer.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, replacing them together is often worth considering, but it depends on the condition of each one, not just their age. A furnace and air conditioner installed at different times can still work fine together as long as both are sound. Where it matters most is when one has already failed and the other is close behind. A contractor can check both systems and tell you honestly whether the second one has enough life left to wait.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace or air conditioner in place, and connects it to your ductwork, refrigerant lines, gas line or electrical circuits depending on what the system needs. After that, they test it to make sure it starts up correctly, runs at the right pressures and temperatures, and shuts off the way it should. Ductwork gets checked too, since a new system moving air through old, leaky ducts will not perform the way it is supposed to. The exact steps depend on the type of system and the layout of your home, so a contractor will walk you through what your installation involves.
