"I must say I was blown away by the difference this service made to my home and family. It’s a night and day difference in our home now in regards to our air quality. We did this 5 years ago and had little difference in results. This time around we contacted Kevin because a friend referred him and they where on time, professional and respectful of our space. His knowledge and attention to detail alone made me feel comfortable and now the results reflect that. He’s my go to go guy from now on for me, my family and friends. Best decision ever!!"

"Calvin is everything his reviews claim that he is: polite, informative, on time, honest and reasonably priced. He didn’t try to upsell us with a 5 ton AC coil and TXV like that other company we have been using. Instead he informed us that what he was replacing was a 3 ton unit and replacing the coil with the same capacity would be adequate. That saved us at least $1,000! Will we be calling him for our future HVAC maintenance and repairs? Yes!"

Heating and Air Conditioning FAQs, answered by experts

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 several steps you can take to prevent your AC drain from clogging. This includes cleaning the drain line at least every three months, changing the filter every one to three months, and getting your AC serviced annually. Also, if any problems arise with your AC, hire an HVAC technician to deal with them ASAP.

If your home has an existing forced-air heat system, you can add a central air conditioner to it. An HVAC technician can retrofit your forced-air heating system by installing an evaporator coil onto the furnace plenum, the box next to the furnace that draws in air. Once installed, the air conditioning coils use the furnace’s blower to circulate the air.

No, a furnace is not the same thing as an AC, or air conditioner, but these are both parts of an HVAC system. They both use air ducts to transport cool or hot air around your home to achieve a comfortable temperature set by your thermostat. An AC runs on electricity, while a furnace can use different fuel sources.

If you’re trying to buy a new AC unit, there are a few crucial factors to consider. Look at the cooling capacity, the available warranty, the energy efficiency, and the type of unit. A ductless unit will cost more up front but may be a more viable option if you don’t already have ductwork. Additionally, a unit with better energy efficiency will cost less to run overall, saving you money on your monthly energy bill.
