Pro Tips & Resources

Most HVAC systems last 12–20 years, depending on the type of equipment, quality of installation, how well it's maintained, and how hard it works. Gas furnaces often last 15–20 years, heat pumps average 12–15 years, central AC systems typically last 12–15 years, and ductless mini-splits can range from 12–20 years. Regular seasonal maintenance plays a big role in reaching the higher end of those ranges.

A good rule of thumb: if your system is over 12–15 years old, requires frequent repairs, or the repair cost is 30–50% of a new system's price, replacement may make more financial sense. Newer high-efficiency systems can also lower monthly energy bills, which helps offset the investment over time. Learn More

Installation costs depend on several factors, including system size, efficiency level, equipment type (furnace, heat pump, ductless, etc.), ductwork condition, electrical upgrades, and overall system design. Every East Nashville home is different, which is why on-site evaluations are so important for accurate pricing.

Indoor air can contain dust, pollen, pet dander, mold spores, and other irritants. Poor air quality may contribute to allergy symptoms, asthma flare-ups, headaches, fatigue, and respiratory discomfort. Proper filtration, humidity control, and airflow design can significantly improve comfort and overall well-being. Learn More

Your ductwork is the delivery system for heated and cooled air. If ducts are undersized, poorly sealed, damaged, or improperly routed, you can experience uneven temperatures, higher energy bills, and reduced indoor air quality. Even the best HVAC equipment won't perform properly without well-designed, properly installed ductwork. Learn More

For most homes, replacing your air filter every 30 days is a safe general guideline. However, if you have pets, allergies, construction nearby, or live in a dusty area, you may need to change it more frequently. The best practice is to check it monthly. If it looks dirty, swap it out.

There isn't a one-size-fits-all answer. Proper sizing depends on square footage, insulation levels, window placement, ceiling height, attic ventilation, and more. A system that's too large can cause humidity and comfort issues. One that's too small may run constantly, driving up energy bills. A professional load calculation is the only accurate way to determine the right size. Learn More

In most cases, yes. Heating and cooling systems are designed to work as matched pairs. Mixing old and new components can reduce efficiency, affect performance, and potentially limit warranty coverage. Replacing both at the same time usually ensures better reliability and long-term savings.

Covering your unit can keep debris out, but it's not necessary. If you do cover it, make sure it's turned off and cannot accidentally run while covered. Never operate the system with a cover in place. Many homeowners prefer a breathable top cover to a fully wrapped unit. The best answer here is NO, don't cover your unit.

R-22 refrigerant has been phased out due to environmental regulations. As a result, it's becoming more expensive and harder to find. If your system still uses R-22, future repairs will be costly. Upgrading to a newer system that uses modern refrigerant can improve efficiency and reduce long-term headaches.

An AC system can freeze due to low refrigerant levels, restricted airflow, dirty coils, or blower motor problems. When airflow or refrigerant pressures aren't correct, moisture can freeze on the coil and block proper operation. Frozen systems require professional diagnosis to identify and fix the root cause.

Most systems should be inspected and serviced at least twice per year. Many homeowners choose maintenance visits, once for the cooling season and once for the heating season. Regular tune-ups help prevent breakdowns, improve efficiency, and extend system lifespan. Learn More

Popping noises often occur when ductwork expands and contracts with temperature changes or when ducts are undersized for the airflow. A professional evaluation can determine whether adjustments or modifications are needed.

A zoning system divides your home into separate areas that can be controlled with different thermostats. This allows you to direct heating or cooling where it's needed most, improving comfort and reducing energy waste. Zoning can be especially helpful in multi-story homes or houses with areas that heat or cool unevenly.

Improving indoor air starts with basics like changing filters regularly and keeping vents clean. For more advanced solutions, options include whole-house media filters, air purifiers, and humidity control. Better air quality can reduce allergens and improve overall comfort. Learn More

Check the equipment label for the manufacturer's date and model number. Many systems come with a manufacturer's warranty, often up to 10 years for parts if registered. A licensed HVAC company can help verify warranty status using the serial number.

Regular maintenance, timely filter changes, keeping outdoor units clear of debris, and addressing small issues early all help extend system life. Proper installation and correct system sizing also play a major role in long-term performance.
