"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

If your home has an existing forced-air heat system, you can add a central air conditioner to it. An HVAC technician can retrofit your forced-air heating system by installing an evaporator coil onto the furnace plenum, the box next to the furnace that draws in air. Once installed, the air conditioning coils use the furnace’s blower to circulate the air.

Yes, a frozen AC unit can affect your indoor air quality since the reduced airflow won't be as effective at removing air pollutants, like dust and other allergens. Additionally, ice around the unit can create excess moisture, leading to mold and mildew that can damage your home if you don’t catch it early.

The cost to add Freon to an AC ranges from $100 to $350. It can increase up to $600 for large AC units requiring much more coolant. The cost also depends on how much refrigerant your unit needs. If only a small amount of Freon leaked out, your cost would be on the lower side. A complete replacement of all the required refrigerant can get expensive.

If you know how to identify supply and return ducts, you’ll find that only the supply ducts will have dampers. Although your return ducts can have dampers, it’s not common. If you have one return duct that is pulling in too much air, adding a damper to it can help with overall system performance. However, dampers on return ducts are not a necessary addition for most homes.

Air conditioners can stop working in the middle of the night for many reasons. Your local power grid might shut down late at night. Power surges can also trip your breakers if too much power is being used in the area at the time. If your AC is connected to a digital thermostat, it gets naturally cooler at night, so the outdoor temperature might dip below the automated setting to turn the cooling system off.
