"They replaced a capacitor for $175 and put in 3 lbs of R22 at $75/lb with a sealant that cost $275. Then they cleaned the outside hot coil for $ 100. The total bill including the $39 Angie's list coupon deal I purchased from came to $814. Work was done 6/27/2018 and AC is working well."

"He was on time first of all, no 4 hour window crap he said "I'll be there at 10.00" and he was there at that time. While he was repairing the furnace I asked him several questions about the unit which he answered in a polite, professional and friendly manner. He made several suggstions on what types of units gave the best and most reliable service and what he would charge to install them. My father is a HVAC tech so we called and asked for his estimate on the part and service and the price we got was for parts and service was 30% BELOW his estimate. This was an all around excellent experience, It's Aire Central all the way from now on !!"

"Our heat was not working.  I called Moncrief and then sent someone out the next day.  There was a charge for them to come out (I want to say it was around $80).  They determined the control switch board needed to be replaced.  They did not have the control board for my unit, so they had to order it.  They said it would take a couple days.  They called a couple days later and said they had the part and we scheduled an appointment for the next day.  They installed the part and the heat was working again.
A few weeks later I turned on the air conditioning because the house was very hot.  I heard a loud rumbling that sounded like thunder.  It was coming from the air conditioning unit.  When I turned the A/C off, the rumbling stopped.  I called Moncrief and told them of the problem and they scheduled someone to come look at it the same day.  The guy determined that that the control switch board had not been calibrated, so he calibrated it to our unit.  There was no charge for this.
Everyone I interacted with was very friendly and helpful.  All appointments were set up very quickly.  I plan to use Moncrief again.

"Cesar came out to help when my AC wasn’t cooling properly, and he quickly diagnosed the problem. He found a faulty part that was causing the issue and repaired it, getting the system back to cooling normally. Cesar was professional, knowledgeable, and explained what needed to be done throughout the service. I had a great experience with Climate Heroes and was very happy with the service!"

Air Conditioning FAQs, answered by experts

When an evaporator coil becomes faulty, it can result in various problems within your HVAC system. These problems could include reduced cooling or heating capabilities due to ice formation and obstructed airflow, along with increased energy consumption and higher bills. Additionally, a damaged coil may lead to refrigerant leaks, which are environmentally harmful and decrease overall system efficiency.

Ultimately, if not addressed right away, a bad evaporator coil can even lead to a complete failure of your HVAC system. That’s why timely repair or replacement is crucial to maintaining your family’s comfort and your HVAC’s efficiency.

Dirty filters are almost always the cause of poor airflow, so they should be regularly cleaned and then replaced as needed. The fan blades can also get dirty, so they should be cleaned when the unit is turned off. Make sure that the outdoor area around the back of the unit is unobstructed. Trees, shrubs, trash, and other objects could be too close to your unit.

As a general rule, you should have your HVAC system professionally serviced at least once a year, though it's best to follow the manufacturer's specific recommendations. Many experts suggest twice-yearly maintenance: once in the spring for the cooling system and once in the fall for the heating system. This is especially recommended for older units, systems with recurring issues, or heat pumps that provide both heating and cooling. Regular service, which can cost between $100 and $550, keeps the system running efficiently, helps prevent costly future repairs, and saves money on utility bills.

If you don't clean your AC evaporator coils, dirt and debris will build up, which impairs the system's ability to transfer heat. This forces the unit to work harder, leading to inefficient performance, higher energy bills, and frequent breakdowns. Over time, neglected coils can corrode, which may cause refrigerant leaks, or develop mold, ice buildup, and a clogged condensate drain, resulting in poor air quality and an uncomfortable home.

The simplest indicator is how long it’s been since your last tune-up. You should schedule an annual AC tune-up each spring. Beyond that, there are multiple signs that your AC needs a quick check by a professional. These issues include higher-than-average energy bills, decreased air flow from vents, higher indoor temperatures, and an air conditioning unit that stays on all the time or frequently turns on and off.
