What Denton summers ask of a new air conditioner
Cooling season here runs June through September, four months of work for your air conditioner while the rest of the year it sits idle. Summer afternoons average 86°F, and that's the load it has to answer every one of those days.
Any new central air conditioner installed today has to meet 14.3 SEER2, the federal minimum. Caroline County has also seen its share of damaging wind, 75 events over the past ten years, so where the outdoor unit sits and how it's secured matters as much as the equipment itself.

Maryland requires HVAC contractors to hold a state license.
The license comes from the Maryland Board of Heating, Ventilation, Air Conditioning, and Refrigeration Contractors. It covers the contractor, not each job, so it stays on record with the state whether the work is a repair or a full installation.
For your installation, that license is what stands behind the person doing the work. In most cities and counties, an air conditioner installation also needs a permit from the local building office, with an inspection once the work is done.

- What size air conditioner does my house need?
- There's no single number that works for every house. The right size depends on your square footage, how much insulation you have, how many windows face the sun, and the layout of your ductwork. A contractor works this out with a load calculation, not a guess based on the home's age or size alone. Get the size wrong and you pay for it either way. Too small and it runs constantly without keeping up on the hottest days. Too large and it cools the air fast but shuts off before it pulls the humidity down, so the house feels damp.
- Should I replace the whole system or just the outdoor unit?
- If your indoor coil and outdoor unit weren't matched when they were made, replacing just one of them can leave you with a system that never runs at its rated efficiency. The refrigerant and airflow have to match between the two halves. Newer refrigerants and coil designs also don't always pair with older equipment. A contractor can check your indoor coil against the new outdoor unit and tell you whether a match-up will work or whether the whole system needs to come out together.
- Do HVAC contractors in Denton need a state license to work on my home?
- Yes. Maryland requires HVAC contractors to hold a license through the Maryland Board of Heating, Ventilation, Air Conditioning, and Refrigeration Contractors. The license belongs to the contractor, not to any single job, so it covers the person or company doing the work rather than being issued fresh for your installation. Installing a new air conditioner also usually needs a permit from the local building office, with an inspection once the work is finished.
