Pittsburgh Best Heating and Airconditioning


If you’re looking into getting a new air conditioning system installed or retrofitted in your Pittsburgh home or business, you need an EPA and HVAC certified service that will not only get your system up and running promptly, but will have the skill and expertise to optimize it according to the specific layout of your Pittsburgh interior, in order to ensure that it runs properly and at peak efficiency. With John Mullen, you get the kind of knowledge and expertise that assures your system runs properly at all levels, and that your air vents are sized and adjusted to optimize your system’s overall performance.

If you’re looking into an HVAC system that will give you heating as well as cooling options, and save you considerable costs on your energy bill (up to, and in some cases over 35%), then consider a heat pump.

At John Mullen Heating and Air Conditioning, we also offer all of our diverse Pittsburgh clientele thorough air duct cleaning services, and the latest UVC air purifiers that can effectively eliminate airborne pathogens and maintain the healthiest indoor atmosphere for you, your friends, family, and clients.
