Myth: turn it way down and the house cools faster

It does not. An air conditioner has one speed, and setting it to 65 does not make it reach 75 any quicker. All it does is overshoot, so the system runs longer than it needed to and the house ends up colder than you wanted.

This one is worth knowing because it costs money in both directions: you pay to overcool, and then you pay again when the house has to come back up.

Myth: shutting it off all day saves the most

This is the one that surprises people. Turning the system completely off while you are out, then dropping the thermostat far down when you get home, is not a saving in a Houston summer.

Two things go wrong. The house does not just get warm, it takes on moisture all day. Now the system has to remove the heat and everything the humidity brought in, which takes far longer and works the equipment far harder than simply holding a steady setting would have.

And that hard cycling is not free. Systems that get pushed from a large gap every single afternoon wear out measurably faster than systems that hold a steady temperature. You save a little on the bill and pay for it in years off the equipment.

Setting back a few degrees while you are out is sensible. Turning it off is not.

Myth: a bigger unit is a better unit

Oversizing is one of the most common mistakes in HVAC, and it feels like the safe choice, which is why it keeps happening.

An oversized system cools the air quickly, hits the target, and shuts off. It never runs long enough to pull real moisture out, because dehumidification happens over time and not at the moment the temperature is reached. The result is a house that is cold and clammy at once, with the system short cycling on and off all day.

Short cycling is also the fastest way to wear out a compressor. This is why a load calculation matters more than a rule of thumb, and why an honest contractor sometimes quotes you a smaller system than the one you are replacing.

Myth: closing vents in unused rooms saves money

Your system was designed to push a specific volume of air through a specific amount of duct. Closing vents does not reduce what it produces, it just raises the pressure in the ducts, which increases leakage and strains the blower.

The actual way to stop conditioning rooms nobody is in is zoning, which shuts off airflow at the source and tells the system to produce less, rather than forcing the same air through a smaller opening.

Myth: you only need maintenance when something is wrong

By the time you notice a problem, the part that caused it has usually been under stress for a while. A dirty coil does not announce itself, it just quietly raises your bill and your run times for months.

The gap between a system that reaches twelve to fifteen years and one that dies at eight is almost entirely maintenance. It is the cheapest thing on this page and the one people skip first.

Myth: humidity is just a summer annoyance

In Houston, humidity is the comfort problem, and treating it as cosmetic is what leads people to overcool. If the house reads a comfortable number and still feels awful, more cooling is not the answer. Humidity control is.

Handled properly, most households end up raising the thermostat two or three degrees and feeling better, which is where the real saving on the bill comes from.

What actually lowers the bill

• A steady setting rather than big daily swings
• Correct sizing, confirmed by a load calculation and not by matching the old unit
• Humidity under control, so comfort arrives at a higher temperature
• Ductwork that is sealed and correctly sized
• Filters changed on schedule
• Zoning, so you stop paying to condition empty rooms
• Rebates you qualify for and may not know about

Why Are Refrigerant Regulations Changing?

The move to phase out traditional refrigerants like R-410A stems from growing environmental concerns. These refrigerants, widely used in air conditioners and heat pumps, are potent greenhouse gases that contribute significantly to climate change when leaked into the atmosphere.

To combat these effects, the Environmental Protection Agency (EPA) is aligning with the Kigali Amendment to the Montreal Protocol, which mandates the phasedown of hydrofluorocarbons (HFCs) with high Global Warming Potential (GWP). This shift encourages the adoption of eco-friendly refrigerants with much lower GWP levels.

What Refrigerants Are Being Phased Out?

R-410A, the standard refrigerant for residential and commercial HVAC systems, is the primary target of this transition. Its GWP of approximately 2,088 makes it a significant contributor to global warming.

Starting in 2025, HVAC systems using R-410A will no longer be produced in the U.S., and the supply of R-410A refrigerant will be sharply reduced. While existing systems can still be serviced, maintenance costs are expected to rise as the refrigerant becomes scarcer. However, R-410A is anticipated to remain available for at least the next decade, much like R-22, which remains accessible years after its phasedown began in 2010.

What’s Replacing R-410A?

New refrigerants such as R-32 and R-454B are leading the way as low-GWP alternatives. R-32 has a GWP of 675, while R-454B has an even lower GWP of around 466. Manufacturers are already adapting their equipment to use these eco-friendlier refrigerants.

It’s important to note that not all brands will adopt the same refrigerant, meaning HVAC technicians will need to handle multiple refrigerant types.

How the Changes Impact the HVAC Industry

The switch to low-GWP refrigerants will bring substantial changes:

• Manufacturers are redesigning HVAC systems to comply with new standards.
• Technicians must undergo specialized training and certification for handling these refrigerants safely.
• Consumers may see an increase in equipment costs due to added safety features and system compatibility.

What Homeowners and Businesses Should Do

While there’s no need for immediate action, planning ahead is key. Here’s how you can prepare:

1. Upgrade Before 2025
   If your current HVAC system is nearing the end of its lifespan, consider replacing it with a new R-410A system before 2025. These systems are expected to be more cost-effective compared to the newer, low-GWP models, which may cost an additional $2,000–$3,000.
2. Plan for Low-GWP Systems
   If upgrading now isn’t feasible, plan for a system using R-32 or R-454B refrigerants. These systems align with long-term environmental goals and may save on maintenance costs as R-410A prices rise.
3. Prepare for Increased Maintenance Costs
   If you keep your current system, anticipate higher costs for R-410A refrigerant and budget accordingly.
4. Stay Informed
   Keep up with industry updates to ensure you’re ready to make informed decisions about your HVAC needs.

Conclusion

The refrigerant transition in 2025 is a necessary step towards reducing the environmental impact of HVAC systems. While this shift may involve added costs and adjustments, it’s an opportunity to invest in a more sustainable future. By understanding the changes and planning ahead, you can ensure your home or business remains comfortable and energy-efficient for years to come.
