"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."

"We found SmartHouse almost by accident while looking for solutions to what turned out to be botched previous AC installation by a much bigger and more established company who we had trusted to do a decent job. Instead we ended up with a system that wouldn't cool the house. Smarthouse first correctly diagnosed the problem, then fixed it, and advised us on how best to heat and cool our 100+ old house. We now have a service contract with them for regular maintenance and they recently installed a mini-split for us. Their techs are great. Just the sort of people we would feel comfortable leaving alone in the house to finish a job if necessary."

"Sam was great. Had a extremely dirty system that would not function correctly or blow cold air. Had High Ridge Heating and Cooling here as he has done work before for me and parents. He took one look and stated we needed to replace entire a/c furnace unit for $3100. Told us it would cost about the same to clean. No way I could afford that so went on Angie's List to find someone and read Sam's review's. He came out and told me the cost at $425 to clean. Which was fantastic. He spent about 2 1/2 to 3 hours and did a wonderful job. Ended up paying total $625 once he was done and asked me before doing anything additional that would cost more. Also since our unit didn't have valves on system to reuse our refrigerant he had to put new in which was part of price increase. Sam, thanks so mich for not trying to take advantage."

"Vitt was very responsive while we investigated alternatives, and provided prompt answers to our many questions. Once we made the decision based on Vitt's good price and excellent equipment, they began the very next day and installed three complete HVAC systems (furnaces, coils and outside units) in one day. Very professional and superior work. We highly recommend Vitt."

FAQs for window a/c unit service or relocation projects in Saint Charles, MO

If your window air conditioner is relatively new or of high quality, repairing it can restore optimal performance and protect your investment. However, for older units or those with ongoing issues, it might be more cost-effective to replace the unit to ensure long-term efficiency and reliability. Consider the unit's age, the severity of the problem, repair costs versus replacement, and energy efficiency ratings when making your decision. If repairs cost more than half the price of a new unit, replacement is typically the better option.

Window air conditioners last eight to ten years on average. After this time, you may notice decreased efficiency and component wear. Replacing an older unit can improve energy savings and provide updated features like remote controls and better overall performance. With proper maintenance including regular filter cleaning, coil checks, and professional servicing, you can maximize your unit's lifespan.

If your portable AC isn't cooling, it might have a refrigerant leak or a circuit malfunction that's preventing it from working properly. It's best to contact a local air conditioner contractor to inspect and repair the unit. If your AC is older and repairs don't fix the issue, replacing it might be the most effective solution.

Removing a wall-mounted AC costs $55 to $75. Completing the removal yourself at the end of each summer season, being sure to do so according to proper guidelines, keeps you within this cost range. Should you require professional assistance for removal and disposal, if you can't move the unit yourself, expect an added fee of $25 to $50 to the overall cost.
