Certifications That Matter

Signs It’s Time to Replace Your AC System

The repair-versus-replace question is what most Covington homeowners are working through before they ever call an HVAC company. There’s no universal answer, but a few patterns consistently point toward replacement.

System age: A unit 10 to 15 years old is approaching or past its typical service life, even with good maintenance.
Recurring breakdowns: A system that needs a repair every season has lost its reliability.
Rising utility bills: Aging equipment loses efficiency and draws more electricity to deliver the same cooling output.
The 50% rule: If a repair estimate approaches half the cost of a new system on a unit over 10 years old, replacement is typically the stronger investment.
R-22 refrigerant dependency: R-22 is no longer produced or imported into the United States. Systems that depend on it face a shrinking refrigerant supply and rising service costs with every repair.

Our NATE-certified technicians can inspect your existing system, walk you through the repair-versus-replace picture honestly, and provide a free estimate if a new system makes sense. That conversation is straightforward and no-pressure, because it should be.

Selecting the Right AC System for Covington’s Climate

Covington’s Northshore location means sustained heat and humidity for most of the year. Proximity to Lake Pontchartrain amplifies that humidity, placing heavier demand on cooling equipment than drier climates do. Picking the right system for this environment involves more than matching square footage to a tonnage number.

Proper Sizing

A correctly sized system accounts for square footage, ceiling height, insulation, window placement, and local climate conditions. An undersized unit runs constantly without reaching setpoint. An oversized unit short-cycles, shutting off before it removes moisture from the air. Both outcomes are uncomfortable and hard on equipment.

SEER Ratings & Operating Costs

SEER (Seasonal Energy Efficiency Ratio) measures how efficiently a system converts electricity into cooling output. Higher SEER ratings can mean lower monthly operating costs for the same amount of cooling, which adds up when the system runs eight or nine months a year.

Variable-Speed Systems in High-Humidity Climates

Variable-speed systems modulate output to match demand rather than running at full capacity until they shut off. In Covington’s climate, that distinction matters for humidity control: longer low-speed cycles can move more air across the coil and remove more moisture from indoor air. Our Trane Variable Speed certification means we can assess whether this type of system is the right fit for a given home and install it correctly when it is. In St. Tammany Parish, dehumidification performance belongs alongside cooling capacity as a criterion when choosing air conditioning replacement equipment.

Protecting Your Investment After Installation

A new system’s manufacturer warranty is only as strong as the maintenance record behind it. Many manufacturers require documented annual maintenance to keep coverage valid, and equipment registration is typically the first step in that process. Nu-Air Heating & Cooling, LLC has an equipment registration page to help homeowners complete that step after installation.

Our maintenance plans are tailored to different systems and budgets. Scheduled service lets our technicians catch minor issues before they become costly repairs while helping maintain the warranty coverage you paid for intact.

Hear From Our HappY Customers

The crew was polite, clean and well presented.
“They are extremely professional and knowledgeable. I was very impressed with their extensive knowledge of the unit, product and professional standards. The crew was polite, clean and well presented. They were even the lowest quote but provided thorough knowledge that exceeded their competition.”

Denise
Edgar is truly a dedicated and rare find.
“Finally, after 4 years of dealing with incompetent air conditioner repairmen I have found a truly knowledgeable technician in Edgar Mejia, owner of Nu-Air Air Conditioning Repair.”

George H.
Trustworthy and the only call I would make.
“Edgar was quick to respond and provided us with options on a new system which were more competituve than the quotes we received. In 36 hours we were financed and cool with a system with the system we wanted for AC and heat.”

Samantha
Great service, professional, and prompt.
“Fixed my air conditioner after hours in a timely manner. I would recommend them to everyone!”

Chuck S.
Stands out from the rest.
“My AC went out on a Thursday night in the middle of the summer and after calling several HVAC companies who couldn't get to me until the following Monday, I called Nu-Air. Nu-Air arrived within a couple of hours and diagnosed my problem. Edgar walked me through my options and had estimates to me the same evening. Edgar located equipment at the distributor, picked it up, and worked late into the night to give my wife and I relief from the summer heat. I had my new AC system installed and the house cool before the other companies could even make it out to assess the situation. Nu-Air truly stands out in a world where customer service has mostly been lost.”

Kevin
He has been taking care of my family's heating and cooling needs for years.
“Edgar is fantastic! He has been taking care of my family's heating and cooling needs for years. I am not an easy customer, as I am very particular with how I expect things to be done. Edgar continues to exceed my expectations! Today he performed the seasonal maintenance for both the upstairs and downstairs units. In addition, he installed the REME-HALO Advanced Environmental Air Treatment System on both units. Edgar recommended this to us, as we have two dogs, two cats, and a rabbit (a lot of paws per square inch in our CBD residence)... The installation was very clean and seamless. The condo already smells better/cleaner (no pet odor at all), and my son's allergies seem much better (no sneezing, no coughing)... Edgar even took the time to register the purchase with the manufacturer to satisfy the warranty requirements. That is service above and beyond! Extremely profession, knows his craft, and always honest... Please do not hesitate to message me, should you require more detailed information. I highly recommend NU-Air Heating and Cooling!”

Michael B.
They are reliable, the work was done when promised and they cleaned up the work area.
“Edgar and crew installed a new electric panel at my house, they also moved a/c return and a few other things. They are reliable, the work was done when promised and they cleaned up the work area and even swept my floor. Thanks for the great work.”

Lorena
I tried 5 different HVAC contractors over 24 years in this house but in the future I will call Edgar Mejia first.
“I am a meticulous DIY handyman myself and I was completely satisfied with the work that Edgar did for me. He replaced the evaporator coil, transition, plenum box and first 25 ft of duct for the ground floor system. He also lined (and sealed) the return air passage. While he made several work scope additions during the job, Edgar made no attempt to increase the agreed upon price. Edgar approached my project as if he was working on his own system. I highly recommend this HVAC contractor.”

Marvin
Customer for life...thank you.
“A friend recommended Edgar to me, couldn't do another year without air conditioning. He worked around my hours gave me different options. Very knowledgeable and professional explained everything to me. I decided to replace old system best decision I made!! I would highly recommend him to anyone if you want fast and wonderful service! Customer for life...thank you.”
