Charleston, SC HVAC Service & Installation

Charleston summers are no joke. Between the soaring temperatures and thick coastal humidity, your air conditioner in Charleston works hard to keep your home cool and comfortable. But if your system is struggling now, it may not make it through another Lowcountry summer without major repairs—or even total failure. At Terrace Heating & Air, we want to help you stay ahead of the heat. Here are some warning signs your AC unit might be on its last legs. 1. Weak or Warm Airflow If your vents are blowing warm air or the airflow feels weak no matter how low you set your thermostat, it’s a clear sign that something’s wrong. This could mean your air conditioning system is dealing with a failing compressor, low refrigerant, or just can’t keep up with Charleston’s extreme summer temperatures. 2. Strange Noises Hearing grinding, rattling, or banging? Those sounds aren’t normal. Your HVAC system should operate relatively quietly. Unusual noises can point to worn-out parts, loose components, or serious mechanical issues—often signs your air conditioner needs replacement. 3. High Energy Bills Has your electric bill in Charleston been creeping up lately? Older or inefficient air conditioning units work harder to keep your home cool. If your system is running constantly but your home still isn’t comfortable, it might be time for an HVAC upgrade. 4. Frequent Repairs Needing one repair every few years is normal. Needing multiple AC repairs in Charleston in a single season? That’s a red flag. Constant issues not only cost you money but also suggest your system is nearing the end of its life. 5. Uneven Cooling If some rooms feel like a sauna while others are freezing, you might have uneven cooling. That could mean your system is too old or too small—or that your ductwork is struggling. Either way, it’s time to have your Charleston air conditioning system inspected. 6. Your AC Is 10+ Years Old Most air conditioners in South Carolina last around 10–15 years, but Charleston’s heat and humidity can shorten that lifespan. If your system is 10 years or older and not keeping up, it’s probably time to consider a new AC installation. Don’t Get Caught in the Heat The last thing you want is for your air conditioner to break down during a Charleston summer. If you’ve noticed any of these signs, Terrace Heating & Air is here to help. We’ll inspect your system, walk you through your options, and make sure your home stays cool and comfortable.

As we say goodbye to winter and welcome the warmer temperatures of spring, it’s the perfect time to prepare your HVAC system for the upcoming change in weather. In Charleston, we experience a unique blend of mild winters and hot, humid summers, making HVAC maintenance essential to ensure your home stays comfortable throughout the year. Here’s how you can get your HVAC system ready for Charleston’s spring weather. 1. Schedule a Professional Spring Maintenance Check Spring is the perfect time to schedule a professional maintenance appointment. HVAC systems that are well-maintained are more energy-efficient and last longer. A professional technician will inspect and clean the system, check refrigerant levels, and address any wear and tear that may have occurred during the winter months. By catching small issues early, you can avoid costly repairs down the road. 2. Change the Air Filter Air filters play a crucial role in maintaining air quality and system efficiency. Over time, filters become clogged with dust, dirt, and debris, making it harder for your system to circulate air effectively. Spring is a great time to change your air filter to ensure proper airflow and maintain a clean, healthy home environment. 3. Clean the Coils and Condenser Unit If you have an outdoor condenser unit, make sure it’s clear of debris, dirt, and leaves that may have accumulated over the winter. Clean the coils and check for any damage that could affect the system’s performance. Keeping the area around the unit clear will allow it to run more efficiently during the hot Charleston summer months. 4. Test the Thermostat As the weather warms up, you’ll rely more on your air conditioner. Test your thermostat to ensure it’s working properly. If your thermostat is outdated or malfunctioning, it could cause your HVAC system to work harder than necessary, leading to higher energy bills. Consider upgrading to a smart thermostat for improved control and energy savings. 5. Check for Air Leaks Springtime in Charleston can bring unpredictable weather, with sudden rainstorms or humidity spikes. Make sure your home is sealed properly by checking for drafts around doors, windows, and ducts. Sealing air leaks can prevent your HVAC system from overworking and help maintain a consistent indoor temperature. 6. Clear Drainage Lines As your HVAC system works harder to keep your home cool during the warmer months, condensation will build up. It’s important to check and clear your drainage lines to prevent clogs that could lead to water damage or system malfunctions. Clean and inspect the drainage lines regularly, especially after a heavy rainstorm. 7. Upgrade Your Insulation If your insulation isn’t up to par, your HVAC system may have to work harder to maintain the desired temperature. Spring is a great time to check your home’s insulation, particularly in attics, basements, and crawl spaces. Adequate insulation keeps cool air inside during the summer and helps regulate your home’s temperature more effectively. 8. Consider Upgrading Your System If your HVAC system is more than 10 years old, it may be time to think about an upgrade. Newer models are designed to be more energy-efficient, which can save you money in the long run. If you’re unsure about the condition of your current system, Terrace Heating & Air can help you assess its efficiency and provide recommendations.
