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

It’s not customary to tip HVAC technicians, and most professionals won’t expect it. However, it’s a nice way of showing your appreciation for the work they do, especially if they come out in inclement weather or on a weekend or holiday to fix an emergency issue if your heat or AC goes out in extreme temperatures. A good tip would be between 10% to 20% of the total bill, depending on how above and beyond the tech goes for your repair and on the total cost of your HVAC repair or service. For something like a routine tune-up or scheduled maintenance, tips aren’t expected.

An AC inspection costs anywhere from $75 to $200, while a full HVAC system inspection that includes your furnace ranges from $200 to $450. While there's a cost to a home AC inspection, it can save you hundreds or thousands in the long run by catching problems, avoiding breaks, and saving you money on your utility bills.

While Freon is mostly odorless, a Freon leak will produce a faint chloroform-like smell. Some people find that Freon's odor has a subtle sweetness to it. Some telltale signs of a Freon leak beyond odor include ice crystals on your evaporator coil, bubbling sounds, and hissing noises.  

Yes, a dirty evaporator coil can freeze up. Dirty evaporator coils can’t absorb or transfer heat properly. The dirt and grime restrict airflow, which is needed to move heat throughout the system properly. Your air conditioning unit could freeze over, or it can cause your heat pump to freeze.

If your HVAC system's capacity doesn't match the required CFM (Cubic Feet per Minute), imbalances can occur. An undersized system struggles to maintain desired temperatures, leading to discomfort. An oversized system might short-cycle, wasting energy and causing temperature fluctuations. Properly matching capacity to CFM ensures efficient and consistent heating, cooling, and home ventilation system performance.
