"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

As a general rule, you should have your HVAC system professionally serviced at least once a year, though it's best to follow the manufacturer's specific recommendations. Many experts suggest twice-yearly maintenance: once in the spring for the cooling system and once in the fall for the heating system. This is especially recommended for older units, systems with recurring issues, or heat pumps that provide both heating and cooling. Regular service, which can cost between $100 and $550, keeps the system running efficiently, helps prevent costly future repairs, and saves money on utility bills.

Evaporator coils in an HVAC system typically last between 10 and 15 years, which is roughly the same lifespan as the entire AC unit. The longevity of the coils can be affected by usage frequency, environmental conditions, and how well they are maintained. Regular maintenance, such as cleaning and inspections, can extend their durability. If the evaporator coil fails in an older air conditioner, it may be more cost-effective to replace the whole unit rather than just the coil.

Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.

To diagnose a bad HVAC or AC damper, assess the airflow from your vents. For a manual damper, close it, run your system, and check for airflow. If air is still coming through the vents, the damper is likely faulty and needs repair or replacement. For an automatic damper, turn on your HVAC system and monitor the airflow and room temperature. Signs of a problem include low airflow, a room that won't maintain its set temperature, or a drafty feeling. If you suspect a faulty automatic damper, you may need to hire a professional for repairs.

Yes, it’s important to turn off your AC sometimes to give it a break and prevent it from freezing up. If your AC runs all the time, your system’s parts will wear down quicker, which may mean that you need to replace it sooner. Plus, using your AC constantly uses more electricity and leads to higher energy bills.
