"Service was very professional from Angel and Luis. Got the AC unit tuned up and checked it. Cleaned the ac unit and it needed to be leveled out got it all leveled out in no time. We have used this company the last few years and will have them back out in the fall to check out the furnance. Eric and his employees are very professional in every aspect and knowledgeable"

"They spared me the immediate need to replace a furnace on Christmas Eve by making a simple and cost-effective repair. This was after other HVAC professionals had looked the equipment over and declared it unfixable. Not only did they come out on the eve of a major holiday but they were courteous, professional and did the exact opposite of an upsell. Exactly the kind of people with whom I like to do business and that I like to recommend to others. If not for David, we would have had a very cold and/or unexpectedly costly Christmas."

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!

Heating and Air Conditioning FAQs, answered by experts

The standard HVAC warranty is around five years. Still, many brands offer an extension to 10 years if you register the product within a specific timeframe, typically 60 to 90 days post-purchase or HVAC installation. Over the past decade, warranty periods have substantially increased, shifting from 3-5 years in the 90s to the now-prevalent 10+ year warranties. Both warranty types cover parts failing due to manufacturer defects, incurring no additional costs. Some manufacturers provide extended warranties surpassing the usual 15- to 20-year window, though these often involve extra fees. 

If the air coming from your AC unit is cool but never quite cold, there are a few reasons this might be happening. For starters, it could signal that your refrigerant levels are low. If there are no other indications of this particular issue, like hissing noises or frozen refrigerant lines, anything from dirty filters to damaged condenser or evaporator coils could be responsible for the problem.

Deciding whether to replace just the AC coil or the entire system depends on the age of your unit and the overall cost. Replacing a coil is less expensive than a full system replacement, but it can still be a pricey repair. If your HVAC system is relatively new and still under warranty, or if the replacement cost is significantly lower than a new system, replacing the coil can be a worthwhile investment that restores efficiency and extends the unit's life. However, for older systems (nearing the end of their 10-15 year lifespan) or those with extensive damage, it is often more cost-effective to replace the entire AC unit. Mismatched coils in an older system can lead to inefficiency and future breakdowns, so a full replacement ensures optimal performance and avoids further costly repairs.

There are a few ways to determine if a vent is open or closed. You can inspect the vent and examine the position of the fins. If there are spaces between them, the vent is open. If the fins are flat and touching, the vent is closed. You can also stand under the vent when the system is running to see if you feel air flowing through it.

The higher the BTU rating an air conditioner has, the more effective it can be at cooling your space. It will cool off your room faster in the short term. However, over the long term, if the unit has too many BTUs for the space, it can wear down the unit faster and shorten its life span.
