To tell if your HVAC air filter needs replacing, perform a visual inspection: remove the filter and hold it up to a bright light. If the light cannot pass through, or if it looks dark gray and clogged with dust, hair, and debris, it should be changed.
The $5,000 rule is a guideline to help homeowners decide whether to repair or replace their HVAC system. You multiply the age of your unit by the cost of the needed repair. If that number exceeds $5,000, replacing your HVAC system is often more cost-effective.
Air purifiers do not dry out the air—they are designed to remove pollutants, not moisture. If you experience dryness, it's likely due to environmental factors like heating systems or low outdoor humidity.
Goodman furnace filter sizes vary widely depending on the specific model and the type of air handler or media cabinet installed. Because sizes are tailored to your system's setup, there is no single "standard" size.
Yes, an air filter can absolutely cause an engine misfire. If the filter is severely clogged or installed improperly, it disrupts the proper air-to-fuel ratio in your engine, which can lead to incomplete combustion and fouled spark plugs.
No, you should not use WD-40 to oil an air filter. It is primarily a penetrating solvent and water displacer, not an air filter oil. Using it will leave your filter dry, fail to trap dirt effectively, and could potentially damage foam materials.

Which HVAC Brands Last the Longest?
The term "Goodman lawsuit" usually refers to the ongoing litigation involving the bankruptcy of the telecom company Goodman Networks and FedEx, or the historical class-action and federal cases regarding defective HVAC evaporator coils manufactured by Goodman Global.

Here are five clear signs your home air is too dry—and what helps.
Standard air purifiers do not add, remove, or significantly affect humidity. They are designed to circulate and filter indoor air. If the air feels dry while running one, it is usually because the airflow creates a cooling sensation on the skin, similar to sitting near a fan.
Key Takeaways. A dirty filter can make you sick, worsening allergies, asthma, and even causing musty odors that signal mold. Replacing a clogged filter can cut HVAC energy use. A “black” filter may harbor mold that sends spores back into rooms.
The "two-foot rule" in HVAC is a duct design and installation guideline that requires a minimum of 24 inches of straight, uninterrupted space between branch take-offs (where air taps off the main trunk). It is also applied to spacing branches away from end caps, transitions, and the main plenum.
Many Amish homes are built with plenty of windows to help circulate the air and bring in the cooler overnight temperatures. They open the windows on the top floors to help the heat escape while the family retreats to the lower grounds within their homes for comfort.
The life expectancy of an HVAC system typically ranges from 15 to 25 years, depending on factors like usage, maintenance, and system type. Regular maintenance, such as cleaning filters, checking refrigerant levels, and ensuring proper ventilation, can extend the system's longevity.
Understanding Goodman's Manufacturing Origins
While some components and certain product lines are manufactured in China, Goodman's primary manufacturing hub remains in Houston, Texas, where the company has been producing HVAC equipment since 1982.
When looking for the "world no. 1 AC," it largely comes down to whether you mean by global sales volume or by premium features and reliability.

A Goodman furnace typically lasts 15 to 20 years. However, achieving the upper end of this lifespan—and potentially stretching it toward 25 years—heavily depends on regular maintenance, a quality installation, and your local climate.
The top three HVAC brands, consistently rated highest for reliability, efficiency, and smart technology by industry experts and consumer reviews, are Trane, Carrier, and Lennox.
Yes, R-32 is generally considered better than R-410A due to its higher energy efficiency, lower global warming impact, and use of a single compound. However, because it is mildly flammable (A2L classification), it requires dedicated HVAC systems rather than a direct replacement.
The best air filter brand depends on whether you need a whole-house HVAC filter or a portable standalone air purifier. Filtrete is the top overall brand for home HVAC systems, while Levoit and Alen lead the market for standalone HEPA air purifiers.
Cleaning an engine air filter with Dawn dish soap is a highly effective and affordable method. Dawn is a fantastic degreaser that safely cuts through dirt, oil, and grime without damaging cotton, synthetic, or foam filter elements.
Yes, a dirty air filter can absolutely make you sick. As filters fill with dust, pet dander, pollen, and mold, they lose efficiency and begin releasing these trapped contaminants directly into your home's air supply, triggering respiratory issues and allergic reactions.
