Thermostat Installation
Your thermostat controls everything your heating and cooling system does. Air Plus installs the full range of options, from programmable models to smart thermostats you can control from any device, and handles the full installation and configuration so it works correctly from day one.
Cor Home Automation keeps you connected to your home’s comfort, safety, and energy use no matter where you are. Air Plus installs and configures Cor for Greater Cincinnati homeowners and integrates it directly with your existing Carrier heating and cooling equipment.
Many Cincinnati-area homes, particularly those built before the 1990s, fall short of the R-30 insulation minimum required by the national building code. Air Plus installs fiberglass blown-in insulation for open attics, enclosed walls, and ceiling cavities, and upgrading to code-compliant levels may qualify your home for available energy tax credits.
Air Plus fabricates custom sheet metal components in our own shop, which means faster turnaround and parts built specifically for your home’s system rather than adapted from off-the-shelf stock. Our capabilities include custom ductwork, exhaust systems, basement duct installations, dryer vent systems, and specialty fabrication in black iron, aluminum, and stainless steel.

Certified & Trusted Quality

Locally Owned Trusted Since 1993

Most homeowners invest in a new furnace or air conditioner and stop there. The problem is that the equipment around it determines how well it actually performs.


A high-efficiency furnace paired with an outdated thermostat loses efficiency every time it cycles. A poorly insulated attic lets conditioned air escape through the ceiling before it reaches you. Ductwork that does not match your home’s layout loses pressure and leaves rooms uncomfortable.

Trusted Since 1993

Air Plus has been providing these supporting upgrades to Greater Cincinnati homeowners since 1993. Our additional services cover thermostat installation, Cor home automation, fiberglass blown-in attic insulation, and custom sheet metal fabrication built in our own shop.

Every service is installed by the same NATE-certified team that handles your heating and cooling.

Why Cincinnati Homeowners Trust Air Plus for Additional HVAC Services

Every additional service Air Plus installs is treated with the same standard we apply to a full system replacement.

In-House Sheet Metal Fabrication Sets Us Apart

Most HVAC contractors order standard parts and make them fit. Air Plus fabricates custom components in our own shop to the exact specifications of your home's system, which means faster installation, better performance, and no compromises from forcing off-the-shelf parts into spaces they were not built for.

Every Upgrade Is Sized and Selected for Your Specific Home

Air Plus does not recommend a thermostat, an insulation level, or an automation system based on what is easiest to install. Our technicians assess your home, your existing equipment, and your usage patterns before making any recommendations. We recommend what fits your home, not what fits a sales target.

Upfront Pricing Before Any Work Begins

Your technician assesses the job, explains what they find, and presents a complete cost estimate before any work begins. You approve the price first. No hidden fees, no charges added after the fact, and no pressure to add services you did not ask for.

The Same Team That Knows Your Whole System

When Air Plus installs a thermostat or fabricates custom ductwork, the technician doing that work is the same certified professional who services your furnace and air conditioner. Additional services do not exist in isolation, and our team understands your whole system, not just the component they are installing today.

Frequently Asked Questions About Additional Services in Cincinnati

Does Air Plus install smart thermostats, or only standard programmable models?

Air Plus installs the full range of thermostat options, including standard programmable thermostats, Wi-Fi-enabled smart thermostats that can be controlled from any device, and Carrier-compatible smart thermostats that integrate directly with your existing heating and cooling system for enhanced efficiency and control. Our technicians will confirm compatibility with your current system before recommending any model and handle the full installation and configuration.

Cor is a home automation platform that provides remote control and monitoring of your home’s temperature, comfort settings, and safety systems from a smartphone or tablet. It integrates directly with compatible Carrier heating and cooling equipment, allowing your HVAC system to respond to your schedule, your preferences, and real-time conditions automatically. Beyond temperature control, Cor can detect smoke, carbon monoxide, flooding, and open doors or windows, and send you an alert immediately. Air Plus installs and configures Cor Home Automation for both new and existing Carrier system owners.

The most common signs of inadequate attic insulation are uneven temperatures between floors, a top floor that is noticeably hotter in summer or colder in winter than the rest of the house, and HVAC systems that run longer than expected to maintain a set temperature. You can also do a visual inspection: if you can see the floor joists of your attic with no insulation between them, or if existing insulation is below the level of the joists, your attic is under-insulated. The National Building Code requires a minimum of R-30 in attics. Air Plus can assess your current insulation level and recommend the right amount of additional coverage.

Sheet metal fabrication is the process of cutting, forming, and joining metal components to build custom ductwork, exhaust systems, and other HVAC-related metal structures. Most HVAC contractors order standard duct components from a supplier and adapt them to fit. Air Plus fabricates custom components in our own shop using welded black iron, black plate, aluminum, and stainless steel, which allows us to build parts to the exact specifications of your home’s system rather than using off-the-shelf parts that require compromise. In-house fabrication also allows us to complete complex custom installations faster than contractors who depend on third-party suppliers.

Yes. Attic insulation is one of the highest-return energy efficiency upgrades available to Cincinnati homeowners because heat rises, and a poorly insulated attic allows conditioned air to escape directly out of the home’s top. The Department of Energy estimates that homeowners can save between 10 and 50 percent on heating and cooling costs by air-sealing and properly insulating their attic, depending on their current insulation levels and climate conditions. Upgrading to R-30 or above may also qualify your home for available federal or state energy efficiency tax credits.

Yes. Air Plus installs thermostats for any compatible residential heating and cooling system, regardless of who originally installed the equipment. Our technicians identify the correct thermostat type for your system’s wiring configuration and communication protocol before recommending any model, and they test the full system after installation to confirm everything is operating correctly. If you are unsure what type of thermostat your system requires, call (513) 769-0871 and one of our technicians will walk you through the options.

We couldn’t be happier with the work Jon did for us. He hooked up our existing water lines and installed a new utility sink with the water line connection. He was friendly, professional, and paid great attention to detail. Everything turned out exactly as we hoped. If you need a plumber, we highly recommend Jon and the team at Air Plus Heating & Cooling!

They were able to be here quickly and determined the problem promptly. The service diagnostic is very reasonable. They gave me a couple of options on a 21 year old AC and gave me their honest opinion. I appreciate that they understand my situation and are willing to help me get back up and running as soon as possible. Great company and I highly recommend them. Update: they installed a whole new system and very professional install by Dave,Tristian, and Tony. Mike was able to get me an affordable system and he did a great job with having it installed quickly as temps will be in the 80’s next week. I couldn’t be happier with my whole experience with Air Plus.
