Memphis Morning Dew Point Check
Before first call, check outdoor dew point vs. indoor RH. If outdoor DP >70°F, expect condensate complaints. Add 30 mins to diagnose drain + coil.

Showing 20 of 20 tips
Before first call, check outdoor dew point vs. indoor RH. If outdoor DP >70°F, expect condensate complaints. Add 30 mins to diagnose drain + coil.
Stage tools outside attic hatch. Headlamp + 2 waters + phone timer 20min max. Check flex duct sag >4" = 30% airflow loss.
Crawlspace RH >80%? Wrap with closed-cell + mastic, not duct tape. Check for standing water on vapor barrier pushing humidity into return.
MLGW brownouts July-Aug fry caps. Test cap under load, not just MFD. If voltage <197V at contactor, note it - compressor will fail in 14 days.
Memphis river humidity breeds algae in 11 days. Use pan tablets + brush, not just vacuum. Pitch drain 1/4" per foot - check with level.
If 4-ton on 1400 sq ft Bartlett house, humidity complaint inevitable. Check runtime <8 min. Solution: dehumidify + blower speed down, not bigger unit.
Mid-South rule: Check static pressure BEFORE gauges. If 0.9"+ on 3-ton, coil frozen due to airflow, not charge. Don't add refrigerant to a choked system.
1920s Midtown attic has 3" blown cellulose. Sell R-49 + radiant barrier + sealed can lights. Temp drop 18°F attic = 25% load reduction.
Memphis cottonwood clogs coil in 72 hours. Don't power wash fins bent. Use foaming coil cleaner + gentle rinse from inside out. Add coil guard screen.
Memphis lightning + MLGW surges kill boards July. Install hard-start + surge protector at disconnect. Document for homeowner insurance.
Southaven tract homes have one 14" return for 3-ton. Need 400 CFM per ton. Check grille velocity >700 FPM = noise + high static. Add Rescue Metal return box.
Thermostat on exterior wall or in sun = short cycle + humidity. Move to interior hall 52-60" high. If can't move, add remote sensor.
Install float switch in secondary pan AND at air handler. Wire to break R, not just alarm. Test by lifting float - system should shut off.
Memphis vibration from traffic (Poplar Ave) cracks braze joints. Check with soap first at service valves, then electronic at U-bends. Use nitrogen 350 PSI.
Flex duct kinked over truss = 60% airflow loss. Support every 4' with 1.5" wide strap, not wire. No sharp 90s - use metal elbow.
DeSoto County clay soil sinks pads 2" per year. Unit tilts = oil migration + vibration. Level with composite pad + Rescue Metal stand 6" above grade.
Black around vents in Memphis = condensation, not mold (usually). Check supply air 55°F meeting 78°F attic air + 70% RH. Seal boot with mastic + insulation.
Check reversing valve function NOW. Energize/de-energize 5x, listen for whoosh. Memphis heat pumps fail first 40°F night in October - get ahead.
Garage mini-split in Memphis sweats drain line. Pitch must be 1" per foot continuous - no traps. Insulate line full length, not just 3'.
Don't say 'change filter monthly'. Say: 'Bartlett oak pollen March + Memphis humidity June = change every 21 days summer, 45 days winter. Set phone reminder now.'

Hard-won advice from years of metal building installs across the Mid-South.
A site that's off by even 2–3 inches can cause the entire frame to rack. Grade and compact your pad at least a week before install so the ground settles. Wet or soft spots will shift the base rail and void your anchoring warranty.
Regular and A-frame roofs trap debris and pool water in the ribs. Vertical roof panels shed rain and leaves straight down the slope — critical in Tennessee, Arkansas, and Mississippi where spring storms are no joke.
Most customers wish they'd gone one size bigger on roll-up doors. A 10×10 feels huge until you try to back in a lifted truck or a boat on a trailer. If budget allows, go 12×12 on the main bay.
Retrofitting insulation after the building is full of equipment is a nightmare. Double-bubble is the easiest DIY option — install it during framing before the panels go on. Fiberglass batts need a vapor barrier on the warm side or you'll get condensation drip.
Gravel pads are fine for carports and temporary storage, but if you're running a shop or storing anything valuable, pour a slab. Mobile-home anchors in gravel can pull out in a 60 mph gust. Concrete anchors are rated for 130+ mph wind loads.
Some counties in TN, AR, and MS require engineered drawings for anything over 200 sq ft. Don't order your building until you know what your county needs — lead times on stamped drawings can add 2–3 weeks to your project.
Stub up your conduit runs before the concrete is poured. Cutting trenches in a finished slab costs $500–$1,500 and weakens the surface. Even if you're not wiring right away, put in the sleeves so you're ready.
Dark colors (Charcoal, Black) absorb heat — great for cold climates, brutal in Mississippi summers. Light colors (Galvalume, Polar White) reflect up to 40% more solar heat. For shops you'll work in year-round, lighter roofs pay for themselves in A/C savings.
