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

HVAC companies may charge an hourly rate or a flat fee. Hourly rates typically range from $100 to $250 per hour, with an average around $175. Some contractors charge a flat fee for specific services, such as an inspection, which can cost between $150 and $500. The total cost of an HVAC service is influenced by several factors, including: the urgency of the service (emergency repairs after hours or on holidays cost more), the time of year, the type, size, and brand of your HVAC system, the specific repair needed, and whether you have a service contract.

While all portable AC units will collect moisture as part of their cooling and dehumidifying process, whether and how often you need to drain them depends on what kind of unit you have and the natural humidity levels where you live. For example, if you live in a very dry area and have a self-evaporating unit, you may not need to drain your portable AC very often at all. Some units may automatically drain collected moisture out the window through their exhaust vent.

No, it's not advisable to only replace the outside AC unit connected to your system. AC units are designed to work as a cohesive system, and older units work differently than newer units. Therefore, replacing only one component can lead to incompatibilities that affect the system’s performance. Replacing one component can void your warranty, costing you money for repairs.

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

Yes, HVAC zoning is generally considered worth the investment by both experts and homeowners. Zoned systems offer significant benefits in convenience, efficiency, and comfort by allowing you to set different temperatures for various rooms or 'zones' in your house. This ability to heat and cool only the spaces you're using leads to energy savings and lower utility bills. Zoned systems are especially effective in multi-level homes that experience temperature fluctuations, but even smaller homes can benefit from the ability to adjust temperatures more quickly. While the up-front installation cost can be high, many find it's a worthwhile long-term investment, particularly for those who plan to stay in their home for a while.
