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

Yes. It's not just AC filters that get dirty. Ducts can accumulate dust and dirt quickly. Insects and animals can also get into duct systems, creating many problems. Dirt build-up and unwanted guests can constrict the airflow and cause rooms not to cool evenly. You might also see higher energy bills because they're not working as efficiently.

Yes, it’s normal for an AC to drip water. In fact, it’s part of the dehumidifying process that takes place inside your AC unit as the condensation trickles down into the drain pan. However, it isn’t normal for your AC to sound like it’s running water or have large puddles around it. If that happens, you can try the solutions listed above or call an AC repair pro.

To extend your HVAC system’s lifespan, it’s crucial to keep up with maintenance. This includes changing filters and thermostat batteries, keeping the outside unit clean and clear of clutter, and lubricating moving parts. Watch out for leaks, mold buildup, and blockages to ensure your unit stays in good working order. Spotting these issues early can be the difference between a simple, wallet-friendly repair and an expensive replacement.

A new HVAC system combines components to control indoor temperature and air quality. Features include a furnace or heat pump and an air conditioner or evaporator coil, depending on the climate requirements. It also involves a network of ductwork for air distribution, a thermostat for temperature regulation, and electrical connections. Air purifiers or humidifiers can be integrated to improve indoor air quality.

The difference between a home surge protector and an HVAC surge protector is that an HVAC surge protector is designed to protect the components inside your HVAC unit while a home surge protector is installed near appliances and meant to protect your entire home. There are three tiers of whole-house surge protectors, and they are more expensive to install than HVAC surge protectors.
