Boilers

HVAC components tend to have a lot of moving parts, and boilers are no exception: valves, pumps, heat exchangers, and ignition systems are all essential components of a boiler. Whenever one of these parts goes haywire, SG Heating & Air Conditioning can identify the problem and provide you with the repair or replacement you need.

Furnaces and Heat Pumps

Gas and electric furnaces both have their advantages and similar lifespans: 15-20 years. If it’s time to replace your AC system, we advise that you also replace your furnace so that your system is matched for compatibility and efficiency.

Air Conditioners: Central AC and Mini-Split Air Conditioning Systems

Whether you have a central air or mini-split system (also known as ductless or multi-split systems), it’s easy to take your air conditioner for granted until it stops working. If your AC is blowing hot air or not blowing at all, your health and comfort are at stake. To get things back to normal, call SG Heating & Air Conditioning for repair or replacement when you need it most.

Indoor Air Quality Systems

Indoor Air Quality systems are a popular add-on to AC installations, but you don’t need to get a whole new AC system to install an IAQ system. We can also install them to work with the heating & air conditioning system you already have to improve your indoor air quality. IAQ systems can protect against viruses, allergens, bacteria, volatile organic compounds (VOC’s), and other pollutants in the air you breathe.

Humidifiers and Dehumidifiers

Along with air temperature, the latent heat in humidity influences your comfort level. For greater control over your home’s humidity, a humidifier or dehumidifier is a worthwhile investment, and a valuable addition to a heating and cooling system, for many homeowners.

Thermostats

A thermostat is the command center of an HVAC system. From these small, wall-mounted devices, you control the level of heating or cooling in your home or business. From helping you select the ideal thermostat to purchase from us to installing it, we can help! 

AC and Heating System Maintenance

Just as you (hopefully) get your car serviced periodically with oil changes, tire rotations, and other routine maintenance, you can protect your home with routine HVAC maintenance from SG Heating & Air Conditioning. Depending on which plan you choose, we’ll come to your home once or twice a year, carefully completing an exhaustive checklist to keep your heating and/or cooling system running the way it should. Plus, you’ll get access to discounts, priority scheduling for emergency service, and other benefits.
