AC Not Cooling? Here’s When to Repair vs. Replace—Especially During a Heat Dome

Residents are sweating it out as a punishing heat dome is pushing temperature indices over the 100-degree mark, taxing tempers and air conditioning units. When cooling systems fail in temperatures like these, getting them up and running is more than a matter of comfort - it's a safety issue.

No one enjoys paying for costly HVAC repairs, but many homeowners prefer it to purchasing a whole new air conditioner. The experts at Elite Air & Heat of Summerville discuss which component is a deal-breaker, when a unit is too old to repair, and why homeowners should always get a second opinion when installing a new system.

Cranking Up the Heat

South Carolina and several other states are experiencing a heat dome - a weather phenomenon in which an area of high barometric pressure traps hot air and humidity. Heat domes can last anywhere from a few days to a few weeks, depending on the position of the jet stream and the strength of the high-pressure system.

It's no surprise that these extended periods of intense heat put extra strain on air conditioning systems. Heat dome conditions increase the risk of AC compressor failure - the key component that’s vital to cooling. The compressor works like a pump, pressurizing refrigerant gas vapor and circulating it around the system. It's the most important part of the heat, ventilation, and air conditioning system - and the most expensive to replace.

When The AC Won't Crank

Experts expect a surge in AC unit failures during the summer of 2025 due to global temperatures rising, according to Home Alliance. Units that are 12-15 years old are at the highest risk of needing repairs or replacement. But which is the better option?

Many homeowners try to delay replacements to avoid up-front costs. However, older HVAC systems often have hidden costs. Aging components have to work harder, decreasing efficiency and increasing the likelihood of pricey repairs. What’s more, inefficient units often lead to higher energy costs and higher electric bills. Replacing a compressor or other high-ticket components is rarely worth it in aged units. Keeping an older system limping along often results in throwing good money after bad.

Cranky Impulses vs. Second Opinions

It can be tempting to do whatever's needed to get the cool air flowing as quickly as possible. But experts recommend always getting a second opinion concerning investments as large as a new AC unit.

For homeowners unsure about their next step, Elite Air & Heat of Summerville offers informed guidance to help make the right long-term decision.
