Heating & Air Services

Living in Lexington, South Carolina, you know how unpredictable the weather can be. No matter the season, you could be switching from heat in the morning to air conditioning in the afternoon. You rely on your heating and air conditioning system to keep your home or business clean and comfortable, no matter the temperature outside.

Although you may not give it much thought, the efficiency and effectiveness of your HVAC system can impact your life every day. For this reason, keeping your system running smoothly is essential. Our team at Killman Heating & Air offers a variety of services to make sure you stay comfortable, safe, and your heating and air conditioning unit is functioning at its full potential.


The first step to creating a functional, efficient HVAC system is purchasing and installing the right equipment. If you are building a new home, or updating your existing property, you need to make sure that the equipment installed is the proper size for your space and of good quality.

If your existing system isn’t running quite as well as it used to, or decided to stop working on the hottest or coldest day of the season, Killman Heating & Air can evaluate your unit and walk you through the best way to remedy the situation. A local, family-owned HVAC company like Killman Heating & Air has the reputation and experience to help you make the right selections and repair decisions.


One of the best ways to make sure your HVAC system is always running as effectively and efficiently as it can is regular maintenance. During preventative maintenance appointments, one of our HVAC professionals will perform a 21-point inspection. They’ll carefully evaluate all components of your HVAC system to ensure that they are clean and in good working order.

If we find any problems during the appointment, or find something that could cause problems between inspections, we’ll recommend the best way to get ahead of any major repairs or replacements while staying within your budget.
