Five months of real heat, every year

Parkville homes run their air conditioner May through September, with summer afternoons averaging 87°F. That is five months a season, year after year, and a new system needs to hold up to all of it without strain.

This area also sees its share of hail and wind, with 90 hail events and 68 damaging wind events recorded over the past ten years, one hailstone as large as 2.75 inches. An outdoor unit sits exposed to that. Any new central air conditioner installed today also has to meet the federal efficiency minimum of 13.4 SEER2, so that part is settled before a contractor even looks at your home.

What size air conditioner does my house need?
There is no single number that fits every house. The right size comes from a load calculation that looks at your square footage, insulation, window placement, and how much shade your house gets in the afternoon. A unit that is too big will cool the air fast but shut off before it pulls the humidity out, and one that is too small will run constantly on a 87°F afternoon and still fall behind. A contractor can run this calculation for your house specifically.
Should I replace the whole system or just the outdoor unit?
If your indoor coil and outdoor unit are different ages or use different refrigerants, replacing only the outdoor unit usually is not an option. The two are matched at the factory to work together, and mixing an old coil with a new condenser can hurt efficiency and shorten the life of the new equipment. A contractor can check the age and condition of both parts and tell you whether a full system swap makes more sense than a partial one.
Do HVAC contractors in Parkville need a state license to work on my home?
Yes. Anyone installing or servicing central air conditioning in your home needs a state HVAC license. Ask to see the license number before work starts, and confirm it is current. This matters here especially after storm damage, since Parkville has seen 90 hail events and 68 damaging wind events over the past ten years, and a licensed contractor will know how to inspect a system that may have taken hidden damage from hail up to 2.75 inches.
