Got HVAC questions? The team at SAMCO is here to help homeowners across Effingham County, Savannah, and the Lowcountry understand how to care for their systems with honesty, clarity, and real expertise.
How often should I service my HVAC system?
We recommend twice per year before each season, cooling and heating so that we can catch weak components before they become an issue when you need them most. This prevents downtime and maximum efficiency. In our coastal climate, humidity and salt air can speed up wear on components, so regular maintenance keeps your system efficient and reliable.
Our technicians check refrigerant levels, clean coils, test electrical connections, and make sure your system is running at peak performance.
Some systems might require cleanings more often, usually in dusty environments. filters and coils can become compacted faster causing strain on the equipment.
You can learn more about why HVAC maintenance matters at the U.S. Department of Energy.
What do we do during a service visit?
When you schedule a maintenance visit with SAMCO, we take the time to do it right. Every inspection includes a full performance and safety check to make sure your system is working as it should.
Here’s what we do:
- Clean evaporator and condenser coils
- Change air filters
- Check capacitors, contactors, compressors, and control fan motors
- Inspect blower motors and ensure proper airflow
- Tighten and inspect all electrical connections
- Test refrigerant pressures to confirm system balance and efficiency
It’s a detailed process designed to catch small issues before they become big problems. You’ll always get honest feedback about what’s working, what needs attention, and what can wait.
Why is my energy bill so high?
High energy bills often mean your system is working harder than it should. That could be due to dirty filters, low refrigerant, leaky ductwork, or just an aging system. The Lowcountry heat and humidity push your unit to the limit in summer—especially if it’s not properly maintained.
If you notice sudden spikes in your bill, schedule a diagnostic visit. At SAMCO, our residential diagnostic fee is always upfront and transparent: $99 during business hours and $150 for emergency calls. No surprises.
How do I know if I need a repair or a full replacement?
Our team will never pressure you to replace what can be fixed. We’ll show you the facts so you can make the right call for your home and budget.
Here’s a quick rule of thumb:
- If your unit is under 10 years old and the repair cost is less than 30% of replacement, repair is usually worth it.
- If it’s over 12 years old and repairs are frequent, replacement may be the smarter long-term investment.
What kind of HVAC system is best for homes in the Lowcountry?
Here in the Lowcountry, our cold gets COLD and our hot gets HOT, and the humidity doesn’t make it any easier. That’s why we often recommend heat pump systems. They’re energy-efficient, reliable in both heating and cooling seasons, and designed to handle our year-round climate.
For coastal homes, corrosion-resistant coils are a must. Salt air can take a toll on metal components, so choosing equipment built for humid, coastal conditions will help your system last longer and perform better.

How can I improve indoor air quality?
Air quality affects more than comfort—it affects health. In our humid region, moisture and allergens can build up quickly.
Solutions include:
- Regular filter changes
- Professional duct cleaning
- Whole-home dehumidifiers
- UV air purifiers
- Ionizers
Often, a combination of these solutions works best for keeping your air clean and balanced. Our technicians can inspect your system and recommend the right setup to keep your air fresh and breathable.
What makes SAMCO different from other HVAC companies?
