Why is my AC running but not cooling?
  • Short Answer: The usual causes are a dirty filter or coil, low refrigerant from a leak, a failing compressor, or a frozen coil. In Summerville the heavy pine pollen clogs filters and coats coils fast, so a choked-up system that cannot move air is a common reason it runs without cooling. 

Refrigerant does not get used up, so if it is low there is a leak to find and fix, not just top off. In the Pines, a pollen-clogged filter or a dirty coil is one of the first things we check, because it chokes airflow and can freeze the coil. We look at the simple, less expensive causes first and show you what we find before recommending anything bigger, because we would rather fix it right the first time than have you call us back next week.

When the AC quits in the Summerville heat, we get you cool again. We repair central air, heat pumps, and ductless systems all over Summerville, from historic Old Town to the newer communities like Nexton, Cane Bay, and Summers Corner. Out here in the Pines you do not have the salt the coast deals with, but heavy pollen and humidity work systems hard. We diagnose, explain your options, and get your okay before any work. Call (843) 723-3887.

Does pine pollen and humidity hurt my AC in Summerville?
  • Short Answer: Yes, more than salt does. This far inland, salt is not the worry it is on the coast. The real stressors are humidity and Summerville's heavy spring pine pollen, which clogs filters and coats the outdoor coil, choking airflow and making the system work harder.

Think of the filter and coil like the lungs of your system: let the pollen cake them over and the whole unit struggles to breathe. In the Pines, changing the filter every month or two in spring and keeping the outdoor coil clean does more good than anything, and it is the cheapest way to prevent a frozen coil or a breakdown. A yearly professional check rounds it out, and you can fold it into our VIP Maintenance Club. We will tell you honestly what your system needs and what it does not.

Do I need a permit, and is my home in a flood zone in Summerville?
  • Short Answer: A system replacement is permitted through the Town of Summerville, and if your property is in a flood zone the equipment must be raised above the flood level, with an elevation certificate required in some cases. Summerville's flooding is inland and stormwater-driven, not coastal tide, but low spots near creeks and ponds still flood. 

Summerville is its own town, mostly in Dorchester County, so a replacement is permitted through the Town of Summerville, and because the town touches three counties it is worth confirming whether your address is in the Town or in unincorporated Dorchester, Charleston, or Berkeley County. If you are in a flood zone, the equipment must be set above the flood level, an elevation certificate may be required in some cases, and we will handle it accordingly. Refrigerant work is done by technicians certified under EPA Section 608. Treating folks right for the long term is how we have lasted in the Lowcountry since 1947.

A few things to check before you call

  • Set the thermostat to cool and check the batteries.
  • Make sure the AC breaker has not tripped.
  • Check the air filter. In pollen season a clogged filter is the most common, easiest fix you can do yourself.

If those look fine and you are still warm, that is when to call us.

Do you offer same-day and emergency AC repair in Summerville?
Short Answer: Yes. When your AC goes out in the summer heat, we prioritize emergencies and work nights and weekends across Summerville and the newer communities. During peak season it can take a little longer, and we will be straight with you about timing when you call. A hot house with kids, older family members, or pets is not something we ask you to sit on, and Summerville summers do not wait. We move emergencies to the front of the line and give you an honest window rather than a promise we cannot keep. Request service or call (843) 723-3887.

Do I need a permit to replace my AC, and what about the coast?

  • Short Answer: Yes. A system replacement needs a mechanical permit, and the authority depends on your address (your city, or the county if unincorporated). Near the water, flood-zone rules may require the new equipment raised above the flood line, and coastal salt means coastal-rated equipment is worth it.

We pull the mechanical permit for your replacement and have the work inspected, through whichever authority covers your address. On the barrier islands and along the marsh, FEMA flood rules can require the condenser raised on a stand above the expected flood line, and the steady salt air rewards corrosion-resistant, coastal-rated equipment that lasts longer near the ocean. Inland, salt is barely a factor and the focus is humidity and efficiency. We size the equipment and the install to where you actually live, which is the same block-by-block read we bring to every Charleston County, Berkeley County, and Dorchester County job.

Should I repair or replace my AC?

Short Answer: Repair a newer system with a small electrical fix. Replace when it is past 10 to 15 years, runs old R-22, the compressor has failed out of warranty, or a repair tops about half a new system. Many newer Summerville homes are still young enough that a repair is the clear answer.

Under about 8 to 10 years old Past 10 to 15 years old
A one-time electrical part (capacitor, contactor) Compressor failed and is out of warranty
Repair is well under a third of a new system Repair tops about half of a new system
System has been maintained Several service calls in the last couple of years
Uses current refrigerant Still runs obsolete R-22
