When winter rolls around, you’re definitely going to want a reliable home heating system set up. After all, bundling up just to remain comfortable in your own home isn’t a good situation to be in.

Let us help keep your home warm through the coldest months of the year.

Water Heaters

Your home’s water heater is one of the hardest working appliances you have. Every time you use hot water, which is probably multiple times a day, your water heater is working for you. Since you rely on your water heater so much, it’s a good idea to make sure that it receives the best possible installation and service. T&H Mechanical Systems offers complete water heater services. If you need a water heater installed or serviced, give us a call today.

Indoor Air Quality

Indoor air quality is often neglected by homeowners, who aren’t aware of how much of an impact it has on their quality of life. Your indoor air quality is affected by a wide variety of things, including airborne contaminants and humidity. Things like dust, dirt, pollen, germs, and mold spores can cause allergy attacks or make you sick. Humidity imbalances can promote mold growth or weaken your immune system. If you want to improve your indoor air quality and, by extension, your quality of life, take advantage of our services! We can help remove harmful contaminants from your air, and correct the balance of your humidity.

Commercial HVAC

Residential properties aren’t the only ones that need HVAC services. Commercial buildings serve a great many more people, on average, than residential ones. They need HVAC systems that can stand up to the strain of serving just as many. We install, repair, maintain, and replace commercial HVAC systems. Whether you need heating or air conditioning, we can make sure that your commercial building stays comfortable all year round. Call today to schedule an appointment with one of our expert commercial HVAC technicians.
