Choose a system with a qualifying SEER rating to be eligible to receive a rebate. Replace your central air conditioner. Get up to $500 back. Installing a new air conditioner with a SEER (energy efficiency) rating of 14 or higher will help you conserve energy even in the hottest weather. You qualify for a bigger rebate if your current system is still working.  Choose from our list of participating HVAC contractors.

Make sure to request the Ameren Missouri rebate when you schedule your project with a participating contractor. Your participating contractor will install your energy-efficient equipment. When the project is finished, your contractor will submit all of the rebate paperwork to Ameren Missouri on your behalf. You'll receive a rebate check in the mail in 6 - 8 weeks. (Yes, it's that easy!) to frequently asked questions. More Ways to Save Energy Efficient Window Air Conditioner An ENERGY STAR certified room air conditioner is designed with advanced technologies that can save you 10% or more in energy costs over less efficient models. Choose one at a participating store near you, then complete your mail-in rebate application. Electronically Commutated Blower Motor (ECM): Up to $100 back ECMs are high-efficiency furnace blower motors that use advanced technology to save energy. Buy a new furnace with a factory-installed ECM, or retrofit your existing furnace and get up to $100 back.

By upgrading to energy-efficient heating and cooling equipment, you may be eligible for a federal tax credit, in addition to the Ameren Missouri rebates listed above.

Noisy indoor unit, air handler, or furnace are all very common complaints in the HVAC field. But they usually fall into one of six different categories listed below. Some of these noises can also be caused by your air vents. For more information on this topic, click below... Loud scraping, metal hitting metal sound Loud thumping or vibrating noise Rattling, squealing or high-pitched sound Loud pop or bang sound First of all, turn the system off immediately. This is usually the worst of the six different sounds. One cause for this sound is that the blower wheel came loose from the motor shaft, moved and is hitting the blower housing. In this case, if no damage was done to the wheel or the motor shaft, it could be moved back to the proper spot and re-tightened to the motor.

Another and more likely cause is that the blower wheel actually broke, in which case it would need to be replaced. do ac units have copper in themThis makes a very disturbing sound almost as bad as fingernails on a chalk board.why would an ac unit freeze up A third possibility is that a motor mount broke, causing the entire motor and blower assembly to drop and the blower wheel is hitting the housing. reviews on carrier ac unitsIn any case, please shut off the system ASAP when this sound is heard or the repair bill could significantly increase. Sometimes this sounds like an out of balance washing machine. This is usually a blower wheel out of balance. Sometimes the motor itself can become out of balance as well. The sound isn't usually too bad but shouldn't be ignored because it can cause other problems to the system.

If the unit is working fine then most likely it is just a noisy transformer. Some transformers are louder than others and they all hum to some degree. If the unit is not working and a hum can be heard, it could be a bad indoor fan motor and/or capacitor. This applies mostly to Heat Pumps. This is usually refrigerant-flow related, such as a check valve, and it's not always a problem. Some units have noisy check valves or metering devices. If the sound gets louder or annoying and the air filter has been checked, then a service call should be placed. This usually happens when the system fan first starts and/or stops. This is also only found on systems with sheet metal ductwork, and it is usually from the return trunk. When the fan first starts the duct pops in from the negative pressure of the fan. When the fan shuts off, the pressure releases and the duct pops-out. This could be a sign of undersized duct, a clogged filter, closed vents or flimsy duct; (For Gas or Oil-fired systems)

Very Important: If you hear an unusual rumbling sound associated with combustion from your gas or oil-fired appliance, call for service immediately. This indicates what could be a serious problem with the burner portion of your appliance. Turn off equipment if necessary. Out of balance blower wheel Noisy refrigerant check valveToday's heating, ventilation and air conditioning units are more energy-efficient than their predecessors. New air conditioning and heating equipment lasts longer than ever. The end of a furnace's or air conditioner’s service life depends on more than just chronological age. Energy-efficiency issues and the price of any necessary repairs versus the cost of upgrading to a new unit all enter into that determination. Furnace Lifespan The average service life of a new furnace is 15 to 20 years. Most furnace parts that fail during that span are replaceable at a cost that makes repair a better call than replacing the entire furnace. The exception is the heat exchanger, a furnace's single most expensive component.
