"Everything went great. They showed up in the morning and had everything ready to go by about 3:00pm. We replaced an 80% efficient furnace and 10 SEER A/C with the Carrier Infinity 98% efficient and 16 SEER A/C. Because the furnace is a high efficiency condensing gas model it requires PVC intake and exhaust piping. We agreed on a suitable location out the side of the house for the new piping. The install went well. They even fixed an existing return duct in the basement that was blocked off. The basement heats/cools so much better now. In fact, we have 2-story home and the whole house is more comfortable. There's not as much stratification of the temperatures from level to level. As far as the equipment it seems to be running great. Both the furnace and A/C are 2-stage units. This means they operate at two different output levels. The thermostat is the Carrier Infinity Control with WiFi. We had a Nest with our old system, but it is not compatible with the Carrier Infinity line because of the complex controls needed to operate the system. That's okay. This new thermostat is much better anyway. It requires a proprietary communication data bus because it is constantly monitoring the state of the various components (furnace, A/C compressor, ECM fan motor, evaporator coil, etc.) and adjusting the control parameters continuously for optimal performance and efficiency. It will even put the A/C in dehumidify mode where it lowers the air flow across the evaporator coil to more effectively pull water out of the air. We are pleased enough with the system that we'd never use anything other than a high efficiency 2-stage (or even fully modulating) system when/if we ever need to replace things again in the future. This is our second positive experience with these guys. We will continue to use them for any future needs."

"I needed to replace my parents' 40 year old AC Condenser and coil, and replace it with something that worked with the new furnace my father got installed four years prior. They were able to do the work requested, and also offered to redo the furance installation as the previous company installed it right on the basement floor where any backup/water could possibly get into the system. They were very prompt and showed up on time/on schedule. They were very upfront about costs and pricing and there were no last-minute price changes or hidden fees, which I appreciate. Work was done well and they ensured that everything worked before leaving the job site. The gentlemen working were very professional and understanding. I highly recommend them for anyone looking to replace their HVAC or to correct work that was previously poorly done."

"We have used this company for both rental and owner-occupied properties. They replaced the roof, gutters, and worked with the company to make sure that our awnings and other items were replaced. They also worked very well with our insurance company and we had no problems at all. Jacob made everything so easy that if we ever need anything else done and they can do it, they have the job."

FAQs for ducts & vents installation and replacement projects in Saint-louis, MO

Return air vents aren't required in every room, but proper placement is essential for system efficiency. According to industry standards, you'll need one return vent for every 100 to 150 square feet of living space. Ideally, each room would have its own return vent, especially larger rooms exceeding 100 square feet. 

Without adequate return airflow, your HVAC system works harder, energy costs increase, and comfort decreases. A professional assessment can determine the optimal number and placement of return vents for your specific home layout.

Signs that your home needs additional return air vents include rooms that feel consistently stuffy, noticeable temperature variations between rooms, doors that slam shut when the HVAC system operates, or unexpectedly high energy bills. Excessive dust accumulation around supply vents can also indicate inadequate return airflow. 

If you experience these issues, consulting with an HVAC professional can help determine if adding return vents would improve your system's performance.

Supply vents deliver conditioned air into your living spaces, while return air vents draw room air back to your HVAC system for reconditioning. Supply vents push treated air into rooms, while return vents pull air from rooms back toward your heating and cooling equipment. 

Both components are essential for proper air circulation and system balance. Without sufficient return capacity, your HVAC system may experience pressure imbalances that reduce efficiency and comfort.

You should inspect and clean your return air vents at least once annually, according to industry recommendations. However, homes with pets, allergy sufferers, or noticeable dust buildup may benefit from more frequent cleaning. 

Regular maintenance helps maintain good indoor air quality and ensures your HVAC system operates efficiently. Professional duct cleaning, which addresses the entire system beyond just the visible vents, is recommended every few years, depending on your home's specific conditions.
