We work in conjunction with SCE&G and Berkeley Electric Cooperative with whole home energy saving. Mills Brothers Heating and Air provides excellent customer service to the Charleston area. Air quality and temperature is not just about comfort, it is important for good health. For people who suffer from allergies or respiratory problems, improving air quality is a big concern.
Services
When you choose a HVAC company to maintain, upgrade, or replace the heating and air-conditioning systems in your home, you want to hire an experienced company with the knowledge to recommend the best system. Mills Brothers Heating and Air is a locally owned HVAC company with both the experience and knowledge you seek.
Tankless water heaters heat water directly without the use of a storage tank. When a hot water tap is turned on, cold water travels into the unit where the water is heated. As a result, tankless water heaters deliver a constant supply of hot water. You don't need to wait for a storage tank to fill up with enough hot water.
Spray polyurethane foam (SPF) is a highly-effective and widely used insulation and air sealant material. Spray foam insulation is an alternative to traditional building insulation such as fiberglass. There is no superior home insulating material that can seal your home from air and humidity intrusion.
Find out from Mills Brothers Heating and Air where heat is being lost through your home's shell and what you must do about it. We use refined equipment, like a blower door test and infrared camera, to find pinpoint air leaks and areas with poor insulation. Roughly one-third of the home's entire temperature loss usually happens through windows and doors.
Every homeowner wants a reliable and consistent HVAC system to provide the perfect balance of optimum temperature control, improved indoor air quality and supreme energy savings. Spray Foam provides home insulating to maintain the desired temperatures you want in your house and lower energy costs. Air Filtration Products removes contaminants such as pollen, mold and pet dander that aggravate allergies.

It was cold in my house last night thanks to Mills Brothers Heating and Air! He is very knowledgeable, efficient and didn’t leave until the job was done right! He cares about his work and it shows. When it’s hot in your house and in this case a hurricane on the way- he is the man you want!

On February 2014 we used Mills brothers to install a brand new $6000 air conditioner in our home in which we paid cash for. Since then we’ve had to call them out to our house a few times for repairs but we didn’t mind because we had warranty but his time was different because the warranty job he quoted us was going to be $225. We had to beg and constantly keep calling him to get that price after which he was at our house and told us he was going to get a part and would be back and never returned. My husband and I called and finally Brian texted and said he would be by tomorrow and told us price

We have used Mills Bros. for both homes that we have owned. They installed new systems on both projects. Brian has always been responsive, prompt, and professional. Brian is very knowledgeable, and has hands on local experience. We will continue to use Mills Bros, and I highly recommend them to anyone.
