Questions and Answers

My Ecobee thermostat is showing an E1 alert. What does that mean?

An Ecobee E1 alert indicates the thermostat has lost communication with your HVAC equipment. In Old Jefferson, this is often a precursor to a system shutdown. The first step is to check the furnace or air handler circuit breaker and the 3-amp fuse on the control board. If these are intact, the alert typically points to a failing control board, a stuck safety switch, or a compromised low-voltage wire connection—common issues in older systems that a technician can diagnose and resolve.

Why does my AC struggle when it's above 93 degrees?

Your system was designed with a 93°F outdoor temperature as its rated capacity limit, based on local engineering standards. On days that exceed this, which are common, the system must run continuously to approach the setpoint, and indoor humidity control suffers. Modern systems using R-454B refrigerant maintain better capacity and efficiency in this extreme heat compared to older refrigerants. Proper sizing through a Manual J load calculation is critical to minimize this performance gap.

With spring pollen and ozone alerts, can my ducts handle a better air filter?

Upgrading filtration is wise for April pollen peaks and our area's ozone risk. However, your existing insulated flex duct has limitations; installing a standard 1-inch MERV-13 filter often creates excessive static pressure, reducing airflow and efficiency. The solution is a 4- or 5-inch deep-media cabinet filter, which provides superior particulate capture with lower air resistance. This maintains proper system operation while significantly improving indoor air quality.

What should I know about permits and the new refrigerants for a replacement?

Any system replacement in Jefferson Parish requires a permit from the Department of Inspection and Code Enforcement, which ensures the installation meets current mechanical and electrical codes. Since 2025, most new systems use A2L refrigerants like R-454B, which are mildly flammable. This mandates specific safety standards for installation, including leak detectors, revised clearance distances, and specialized technician certification. Using a licensed contractor guarantees compliance with these 2026 safety protocols.

My Old Jefferson system is from the late 80s. Is it really time to replace it?

A system from 1989 is now 37 years old, which is well beyond its expected service life. Units of this age in Old Jefferson are particularly prone to coastal salt-air coil corrosion, which silently degrades efficiency and leads to refrigerant leaks. The original R-22 refrigerant is also phased out, making repairs costly with obsolete parts. Proactive replacement now avoids a mid-summer failure and allows you to upgrade to modern, efficient, and safer refrigerant standards.

Our AC quit on a hot afternoon in Old Jefferson. How fast can a technician get here?

A no-cool call is treated as a priority. From our service hub near the Ochsner Medical Center, we dispatch directly via Jefferson Highway (LA-18), which provides efficient access throughout Old Jefferson. This routing typically results in a technician arriving at your home within 15 to 25 minutes. We recommend turning the system off at the thermostat to prevent compressor damage until we can diagnose the issue.

What does the new 14.3 SEER2 minimum mean for my utility bill?

The 14.3 SEER2 mandate effective in 2025 sets a new baseline for efficiency, measuring performance under more realistic static pressure conditions. For a typical 3.5-ton system in Old Jefferson, upgrading from a 10 SEER unit to a 16 SEER2 model can save roughly 30% on cooling costs at the local rate of $0.11 per kWh. The federal Inflation Reduction Act rebates, with an $8,000 cap, can significantly offset the cost of a qualifying high-efficiency heat pump system, improving the payback period.

I have gas heat. Should I consider a heat pump for my Old Jefferson home?

A modern cold-climate heat pump is a viable primary heat source here, as it operates efficiently down to our winter lows. The economic case is strong when you factor in the IRA rebates and Entergy Louisiana's HVAC Efficiency Program, which offers up to $600. To maximize savings, pair the heat pump with a smart thermostat that uses utility peak hour pricing data (typically 2 PM to 7 PM) to precool your home, shifting electrical load and reducing operating costs.
