Pontotoc Ductwork Replacement, Part 2: New Duct Runs and Final Connections

In Part 1 we pulled out the old ductwork on this Pontotoc home. This week we finished the job by connecting the existing Amana package unit to all new ductwork.

Package units sit outside, so every foot of duct between the unit and the house matters. Old, leaky, or crushed duct means you pay to cool air that never reaches your rooms. We ran new insulated flex duct for both supply and return from the unit's connections, through the foundation and into the crawlspace. Every joint at the unit transition was sealed with duct mastic, not just tape. Tape dries out and lets go over time. Mastic stays put.

Under the house, we hung the supply runs from the floor joists with strapping. That keeps them off the v***r barrier and pulled straight. Flex duct that sags or kinks chokes off airflow, and that is one of the most common reasons one room never gets comfortable.

The unit itself was still in good shape, so the homeowner kept it. New ductwork let them get better airflow without paying for a whole new system.

Duct Replacement Job – Pontotoc, MS

We're on-site in Pontotoc removing old, deteriorated ductwork and replacing it with all-new flex duct. This home was dealing with serious airflow problems along with heat and cooling loss, and the old ducts were sweating so badly that condensation was dripping into the basement — leading to mold growth.

Once the new duct system is in, this homeowner will see better airflow, more consistent temperatures, and no more moisture problems in the basement.

If your ductwork is old, leaking, or sweating, don't wait for mold to become a bigger issue. Give us a call today.

New HVAC system installed today in Guntown, MS.

Our crew installed a new 5-ton system, including rebuilding the attic ductwork and tying in a custom-fabricated plenum to get the duct runs properly connected to the new air handler, along with setting the new outdoor condensing unit. Measurements confirmed the system is cooling properly, with a delta T of just under 19 degrees across the coil - right where it should be. We'll be back out once temperatures cool down a bit to test the system in heat mode and make sure it's ready before fall gets here.

If you need a new system installed before the weather turns, give us a call. We serve Guntown and the surrounding Tupelo area.

AC Not Cooling? It Might Be a Small Part With a Big Job.

We just wrapped up another service call in Saltillo, MS — a failed run capacitor causing the outdoor condenser fan and compressor to struggle to start.

Here's what we found:

Photo 1: Our tech getting into the outdoor unit, pulling the access panel to inspect the electrical components.

Photo 2: The culprit — an 80+5 µF dual-run capacitor. This part stores and releases energy to give your compressor and fan motor the "kick" they need to start up. When it fails, your system either won't start, hums and trips the breaker, or short-cycles trying to cool your home.

Photo 3: Testing the capacitor with our meter — reading 0.023 µF instead of the rated 80 µF. That capacitor was completely dead.

Photo 4: After the replacement, we hooked up our diagnostic tools to verify the system — 15.9° superheat, 4.0° subcooling, all pressures right where they should be. System back up and running properly.

Why capacitors fail:

Extreme heat, like our Mississippi summers
Normal wear and age (most last 5-10 years)
Power surges
Constant on/off cycling during peak season

A bad capacitor is one of the most common — and most affordable — AC repairs out there. Catching it early can prevent a full compressor replacement down the road.

If your AC is humming but not starting, blowing warm air, or your outside unit keeps tripping the breaker, don't wait it out in this heat.

It's the end of July. Nobody in Mississippi is thinking about their heat right now. That's exactly why this is the right time. 🔥

This is the inside of a real furnace we opened up on a call. Rust across the burner area, corrosion on the cabinet floor, wiring that has been cooking for years. From the hallway closet door, it looked completely normal.

That's the part people miss. A furnace doesn't warn you politely. It either works, or it doesn't, or worse, it keeps running while doing something it shouldn't.

Worth having eyes on before the first cold snap:
🔥 Burners and heat exchanger
🔥 Flue and venting
🔥 Safety controls and limit switches
🔥 Wiring and electrical connections
🔥 Filter and airflow

We're licensed on both the electrical and the HVAC side, so it's one call and one truck. No two contractors pointing at each other while you sit in a cold house.

Get on the schedule now, while it's easy to get on the schedule.

Your outdoor unit should not look like a bird's nest. 🌲

This condenser was packed solid with pine straw, and the compressor inside had finally given up. When airflow across the coil gets choked off, head pressure climbs, the compressor runs hot, and one day it just doesn't come back on.

What this job took:
✅ Diagnosis to confirm the compressor was the actual failure
✅ Refrigerant recovered the right way
✅ New compressor installed and a new line set brazed in clean
✅ System evacuated, charged and tested before we left the yard

Here's the part that costs you nothing: keep pine straw, leaves and grass clippings pulled back about a foot from your outdoor unit, and rinse the coil off a couple times a season. That alone can add years to a system.

If yours is running and running without ever cooling the house down, don't wait for it to quit on the hottest day of the year.

Would you sleep easy knowing the panel on the LEFT was behind your laundry room wall? ⚡

That's a real one we opened up right here in North Mississippi. Scorched bus bar. Cloth-wrapped wiring. Screw-in fuses still doing a job breakers were invented for 60 years ago. The homeowner's only warning sign? Lights that dimmed every time the dryer kicked on.

Here's what we did:
✅ Full load evaluation before we touched a single wire
✅ New main panel and disconnect, properly bonded and grounded
✅ Every circuit re-landed, labeled and torqued to spec
✅ Left it inspection-ready before we pulled out of the driveway

A flickering light is easy to ignore. A panel like the one on the left is how a house fire starts.

If yours still has fuses, feels warm to the touch, or smells like anything at all, get eyes on it. We'll tell you straight whether it can wait.
