Hello, My Name is Johnathan Steele, Owner Operator of Show-Me Comfort Heating and Air Conditioning. I started my company with the intent to help and show transparency to my customers and to educate them to the best of my abilities on the system that keeps their Home Comfortable. Most Companies will come in to a house fix the issue then leave… That’s where we try and separate ourselves by finding the culprit, educating our customers on why it happened and how to prevent future problems. \n\nWe at Show-Me Comfort Heating and Air Conditioning take pride in our work, and if we wouldn’t do it in our house we wouldn’t do it to yours.

Heating and Air Conditioning questions, answered by experts

AC evaporator coils should be cleaned at least once per year to keep your unit in good condition. For optimal performance, consider cleaning them twice a year—once before and once after the main cooling season. More frequent cleanings may be necessary for older systems, units with performance issues, or those in climates with high levels of humidity, dust, and dirt.

DIY is possible for basic cleaning. Professional services handle advanced maintenance like recharging the refrigerant.

Split systems are the most common type of HVAC system. Split systems have two main units: an indoor one and an outdoor one. These units work together to pull in air, heat or cool it, and distribute it throughout your home. Other popular types of HVAC systems include hybrid systems and packaged heating and air systems.

Not if you have a standard unit. Because portable AC units actually work to dehumidify the room, you’ll likely need to drain the unit from time to time—but you won’t have to put water into it. There is, however, another type of air conditioner called a swamp cooler that requires water to operate. If you have a swamp cooler, you may need to fill a reservoir with water and potentially ice. But a swamp cooler is different from a standard portable AC unit.

The cost to replace an AC unit averages around $5,900, with a typical range between $3,900 and $8,020. The final price depends on several factors, including the type and size of the air conditioner, its efficiency rating, your geographic region, and labor costs for installation. Smaller units like portable and window ACs are much less expensive, costing between $90 and $550, compared to central or ductless systems. If your current unit is less than 10 years old, repairing it may be more cost-effective than a full replacement.
