Commercial and Residential New Construction
Guaranteed Mechanical designs and installs heating and air conditioning systems for homeowners and businesses throughout the Chicagoland area. Our detailed plans are built to provide the most efficient temperature control for our customer, while maximizing the life of the products installed.
HVAC System Replacement
We approach each job with the customer in mind. We won’t suggest work or new equipment unless it is absolutely necessary. However, even with regular maintenance, HVAC systems will eventually need to be replaced. We provide you with the information that you need to make an informed decision. When our team replaces your system, we assess your overall heating and cooling needs, recommend a solution that is based on your needs and install your new HVAC system with care.
Air Quality & Air Sanitation
We help you improve the indoor air quality of your home or office with quality Humidity Control, Ventilation, Filtering and Air Sanitation & Purification equipment. Our expert installers will help you breathe easier.
HVAC System Maintenance
Residential Tune Up
Just like your vehicle, Air Conditioning and Heating units need regular maintenance to live a long life and perform at their best. Our knowledgeable team of technicians have been with Guaranteed Mechanical for many years, and you are likely to have the same friendly face each time we perform your preventative maintenance.
Commercial Maintenance Plans
Our Commercial HVAC Maintenance plans are designed to heat and cool your commercial property efficiently and effectively. We help you avoid downtime with your critical equipment, and maximize the life of your commercial heating and air conditioning equipment. We perform all service with the same professionalism and reliability that have made us the go to provider for commercial new construction projects in our area.
Radiant Heat Systems
Guaranteed Mechanical installs more than 20,000 square feet of radiant heating each year for homeowners, garages and even luxury motor condos. (Image from Iron Gate, but we should ask permission) Unlike traditional hot air systems, under floor radiant heat provides warmth to your living space without blowing dirt, dust and pet dander around your home.
Restaurants and other food service companies rely on their commercial refrigeration systems daily. They simply need to work, and the risk of increased costs are obvious. Guaranteed Mechanical is trusted by area restaurants for both scheduled and emergency service of their commercial refrigeration systems. Restaurant owners choose us because of the quality of our work, the dependability of our technicians, and because they get to know our team.
