5 Common HVAC Questions Answered

Your HVAC Questions, Answered.

Through our several years of HVAC service in the Lowcountry, we’ve encountered our fair share of air conditioning and furnace issues and installations. We’ve worked on historic homes, new homes, remodeled homes; offices, small and large businesses in Charleston.

With that experience we’ve put together 5 of the most common questions (and answers) about HVAC systems below.

1. How can I increase the efficiency and lifetime of my HVAC system?

While there are several ways to achieve efficiency and longevity of your HVAC system, one of the best ways to is to properly clean/replace your air filters frequently. Most HVAC companies offer this service as part of their HVAC maintenance plan so you won’t have to worry about it if you choose to sign up for one. Another simple thing you can do is have shades or curtains installed in rooms that are exposed to extreme sunlight.

2. How often should I clean or replace my air filters?

To get the best efficiency & filtration, replace or clean your filters at least once a month.

3. How much does a new HVAC replacement system cost?

Because every home, every business and every building is unique (especially in Charleston) it’s nearly impossible to put an exact price on a new system. The good news: you can get a free estimate from us, no obligation.

4. How often should I have my HVAC system serviced?

Regardless of what kind of system you have or how big your HVAC system is, to maintain optimum efficiency and to catch early warning signs of potential HVAC breakdowns your system should be inspected and serviced at least once a year. We recommend twice as some seasons may be harder on your system from year to year.

5. What size air conditioning and HVAC system do I need?

Perhaps the most frequently asked question we receive, it’s also the hardest to answer. Having an AC system that is too large may cool your home too quickly, leaving behind moisture that could lead to mold problems for your home or business. Also, too-large AC systems tend to short-cycle (starting and stopping quickly, repeatedly) which decreases the lifetime of your AC and increases your electricity bills.

At the other end of the spectrum, having a system that is too small won’t ever keep your home or business cool and will run constantly.

Because there is no “rule of thumb” for sizing an AC system only an experienced HVAC company can properly spec out your location and install the system that will yield the best (and most affordable) results.
