"Everttime my furnace would kick on a foul oder would circulate through my home, which I identified as a dead mouse. I inspected and vacumed ,to the extent I was able, each register. I was unable to locate a decaying carcus. My heating and A/C service referred me to Ernest Airduct & Dryer Vent. I hired them to clean and sanitize my duct work throughout my home. I am very pleased to report, that the order is gone. Both their customer sevice and job skill was excellent."

"Our overall experience with Honest Abes for our HVAC replacement went quite well. Equipment, techs, timing was all 5 star. My 4 star rating is for the contractor not providing the manufacturers warranty info. Honest Abes provided thier warranty but l wanted all the warranty info. I went to Goodmans site, entered all serial numbers and received all my data related to our HVAC system. It even list the built date of each item. If Honest Abes starts leaving the manufacturers warratny with their installs, l believe most customers would be more satisfied."

"Tuesday, February 7, 2023, CW (Charles Waterman) of Commercial Home Services In Camdenton Missouri, installed a new thermostat for the furnace in my house in Eldon Missouri. After he had left the thermostat wasnâ t working correctly, so I called him the next day to see if he could return and take a look at it. Over the next few days I contacted him several times. Apparently he had a very busy week, but first thing Monday morning February 13, 2023 he called me back and said that he would go by the house that morning and take a look at the thermostat. He found the thermostat was working but the furnace had several problems which he informed me would be fairly expensive to repair. I have decided to replace the furnace which is over 30 years old with a heat pump. Charles has been courteous and very helpful. I appreciate what heâ s done for us and would recommend him."

Heating and Air Conditioning FAQs, answered by experts

You should use a breathable, weather-resistant cover with ventilation. It can be a top cover or a full cover that has mesh to allow airflow. A full, non-breathable cover can cause moisture to build up, leading to rust, frozen parts, and corrosion. A full cover also attracts unwanted critters, such as mice, that can damage the wiring and your unit. If you need to protect your AC unit from falling icicles, choose a sturdy top cover or piece of wood that prevents icicles from damaging your unit.

This depends on the extent of the freezing. Some ACs only need an hour or two to thaw out, but others may need a full day to completely unfreeze. Once you turn off the system to let it unfreeze, check it periodically to make sure the drain pan doesn’t overflow. When you turn the system back on, keep an eye on it to ensure it doesn’t start freezing again.

Aside from needing HVAC repair, there are times when you may need to replace your unit. HVAC replacement costs $5,000 to $12,500. Here are some telltale signs that your HVAC unit is going bad:

  • Your unit is 10 years or older.

  • Your home is very humid.

  • The unit keeps cycling without producing cool air.

  • You need to repair the unit frequently.

Traditional central air conditioning systems require ductwork to circulate air throughout the home. Alternatively, you can add air conditioning with a mini-split ductless air conditioning system, which can be just as energy efficient as a central air conditioner. This type of system consists of two units–an outside unit that holds the compressor and condenser and an indoor unit that holds an air-handler. With multi-zone ductless systems, there are multiple indoor air handlers tied to a single outdoor compressor/condenser, allowing the system to cool multiple rooms.

Yes. Your air supply should be balanced. The return and supply ducts need to maintain that balance, and this only occurs because an equal amount of air should be entering and leaving your HVAC system. Changes in pressure, extreme weather, and blocking vents with furniture or your stuff can make the air supply unbalanced and cause your home to get too cold or hot.
