HVAC Myths

Alpine Heating and Cooling • August 19, 2020

Most people use HVAC systems to heat and cool their homes throughout the year. Most people don’t fully understand how these units operate, which can lead to some avoidable issues. Listed below are 3 common myths you’ve probably heard.

 

Myth: Lowering the Thermostat Cools Your Home Faster

While lowering the thermostat will help your home reach a cooler temperature, it won't happen quickly. Air conditioners run at one speed, and lowering the thermostat a few degrees at once won't change its cooling capacity. Instead, it will cause the unit to run for an extended period, which can make it overheat and put unnecessary stress on its parts. Additionally, if you lower the thermostat beyond your typical comfort zone it can lead to a lot of wasted energy.

 

Myth: Leaving the Thermostat at a Set Temperature Saves Money

Many homeowners incorrectly believe that if they set the thermostat and never change it, they can save money on their electric bill. Because the outside temperature affects the inside of your home, never moving the thermostat can cause the HVAC system to run continuously or not enough. To avoid either extreme install a programmable thermostat that ensures the temperature automatically changes throughout the day to save energy and keep your home comfortable.

 

Myth: Maintenance Is Only Needed When You Notice a Problem

Regular HVAC maintenance is essential for preventing problems before they happen. Ideally, before you turn on your air conditioner or furnace each season you should have a contractor clean and inspect it. This allows them to look for worn parts and replace them before they break, which could otherwise cause your system to run inefficiently or have a complete breakdown.

If you’ve heard people talking about “new refrigerant rules” for air conditioners and heat pumps, you’re not alone. Homeowners are wondering if their current AC system is suddenly outdated or impossible to repair. The simple answer is no — you do not need to replace your air conditioner just because refrigerant rules have changed. What Changed With HVAC Refrigerants? The HVAC industry is moving away from higher-GWP refrigerants, including R-410A, and toward newer refrigerants with lower environmental impact. Under the EPA’s refrigerant transition rules, many new residential air conditioners and heat pumps manufactured after January 1, 2025 must use lower-GWP refrigerants. Existing systems can still be serviced, and parts used to repair existing systems are not subject to the same restrictions as new equipment. For homeowners, that means your current air conditioner or heat pump does not automatically need replaced. Can My Current AC Still Be Repaired? Yes. If your system uses R-410A, it can still be serviced. The bigger question is whether a repair makes financial sense. As older refrigerants become less common over time, certain repairs — especially refrigerant leak repairs — may become more expensive. That does not mean every older system should be replaced, but it does make the repair-versus-replace decision more important. When Should You Consider Replacing Your AC? You may want to consider replacement if: -Your system is over 10–15 years old -You are facing a major repair -Your AC has a refrigerant leak -Your energy bills keep climbing -Your home has uneven temperatures -Your system uses older equipment that is no longer under warranty If your system is newer, running well, and only needs a minor repair, replacement may not be necessary. Don’t Panic — Get Honest Advice The new refrigerant rules are a real change in the HVAC industry, but they should not be used to scare homeowners into replacing equipment before they need to. At Alpine Heating, Cooling, Plumbing & Refrigeration, we help homeowners understand their options clearly.
