A Healthy Home Begins With Clean Carpets. Protect your family and investment with clean carpets. Nothing cleans more thoroughly than our patented and green ZEROREZ® cleaning system. • Carpet stays cleaner longer: Harsh detergents leave behind residue, which attracts dirt. Because we never use soap, nothing but clean is left behind after our non-toxic water-based agent is applied. • Old traffic lanes and spots are far less likely to reappear: Our process will not penetrate the carpet backing. Stains are pulled from the padding back into the carpet fibers through a wicking action. • Carpets aren't soaked during cleaning: No soaking cuts down drying times. • Highly trained, uniformed, full-time technicians: We are professionals. Our respectful techs will be a pleasure to have in your home. Trust our ZEROREZ® experts to clean carpets like no one else in the Kansas City area -- our patented process assures it! No residue means carpets stay cleaner longer.

"They were outstanding in every way!! They temp loaned a window unit until they could install the new one and waited a week after installation before charging. When I asked them why they waited for payment, they said it was because they wanted to make sure everything was installed correctly and there was nothing wrong with the AC unit itself. I wish more businesses were like Alliance Heating and Cooling and also wish they were in more states!"

Heating and Air Conditioning FAQs, answered by experts

The $5,000 rule for HVAC systems helps homeowners decide whether to repair or replace an AC or furnace. Take the quote for the HVAC repair cost and multiply that by the age of the HVAC system. If the total is higher than $5,000, it’s more cost-effective to replace the system. If the total is lower than $5,000, consider repairing the system.

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.

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.

No, heat pump maintenance needs are very similar to air conditioners, including keeping outdoor units clean, changing filters regularly, and occasionally scheduling a refrigerant check to see if any has leaked out. Heat pumps typically switch automatically between heating and cooling, so you don’t need to worry about manually changing them every season. However, since they are always on call, they can develop wear and tear faster than an air conditioner.

No, it’s not normal for AC vents to drip condensation. A sweating AC vent is a sign of something wrong and can lead to issues like air duct rust or mold growth. Your HVAC unit might not be working efficiently because of a dirty filter or clogged ducts. Alternatively, your ductwork might not have adequate insulation, which allows the cool air in the ducts to meet the humid air outside, causing condensation.
