A system that works almost every month of the year
Cooling runs April through October here, seven months of afternoons near 91°F. Heat picks up the other five, November through March, with winter nights averaging 42°F. Between the two, a new system in Mobile County is doing one job or the other almost all year.
Most homes here heat with electricity, and the power doesn't always stay on. Nearly one in five Alabama households lost power for a full day or more in 2024, and this area has logged 155 damaging wind events over the past ten years. A system installed well is one less thing to worry about when the weather turns.

Alabama requires HVAC contractors to hold a state license.
The Alabama Board of Heating, Air Conditioning & Refrigeration Contractors tests and licenses the contractor, not the job itself. The license tells you the person doing the work passed the state's exam and is on record with the board. It does not mean the board signs off on your installation once it is done.
That sign-off comes from somewhere else. In most cities and counties, a new furnace, air conditioner or heat pump needs a permit from the local building office, and the finished work gets an inspection before it is considered done. The license tells you who is allowed to do the job. The permit and inspection tell you whether this particular installation was done right.

- When should I replace my HVAC system?
- Look at the age first. Once a furnace or air conditioner is old enough that parts get hard to find, repairs start costing more and happening more often. If your system is breaking down more than once a season, or a contractor tells you the same repair is likely to happen again, replacing it is usually the better move. Here, homes need heat or cooling all 12 months of the year, so an aging system has no real off season to coast through.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, replacing them together makes sense. A furnace and air conditioner installed at the same time are matched to work as one system, and pairing new equipment with an old, worn piece often means the older one fails first anyway. If only one has actually failed or is showing its age, a contractor can look at both and tell you whether the other has enough life left to wait.
- What happens during an HVAC installation?
- A contractor first sizes the new equipment to your house, since a furnace or air conditioner that is too big or too small for the space will not heat or cool it properly. The old equipment comes out, and the new furnace, air conditioner, coil, or ductwork connections go in along with any electrical or gas line work the new unit needs. Once it is running, the contractor tests it, checks refrigerant levels or gas pressure, and walks you through the thermostat and any settings specific to your new system. The exact steps and timeline depend on what you are replacing and the condition of your ductwork, so a contractor will lay out the specifics for your house before starting.
