Frequently Asked Questions

​Great question! Even if your system seems to be running smoothly, routine maintenance is key to keeping it that way. We recommend scheduling maintenance twice a year to help ensure your system remains reliable, efficient, and ready when you need it most.

Our certified technicians don’t just give your system a quick once-over — we perform a thorough inspection to catch small issues before they turn into costly breakdowns, especially during peak seasons when you depend on your comfort the most.
Think of it like an oil change for your car: regular care now helps prevent major repairs later. Want to know what we check during a tune-up? Visit our blog for a deeper look into the specific maintenance items we cover.

During the summer months, one of the leading causes of HVAC breakdowns is a clogged condensate drain line. That’s why every preventative maintenance visit we perform includes a thorough drain line cleaning—keeping your system running smoothly and helping you stay cool when it matters most.

While HVAC systems are built to last, the component we replace most frequently is the capacitor. This small but essential device—roughly the size of a baseball—stores energy and delivers a quick surge of power to get your air conditioner running when the thermostat calls for cooling.
In Florida’s extreme heat, the capacitor is under constant stress. Over time, the dielectric grease inside can dry out, leading to failure. That’s why regular maintenance is key to catching early signs of wear and preventing unexpected breakdowns.

A good rule of thumb: if the cost of repairs approaches 30% of the price of a new system, it’s often more cost-effective to replace. Another key indicator? If your utility bills have significantly increased, your current system may be losing efficiency and costing you more in the long run.
Our team is always here to help you weigh your options with honest recommendations tailored to your comfort, budget, and long-term savings.

Indoor Air Quality (IAQ) refers to the condition of the air within and around buildings—particularly as it relates to the health, comfort, and well-being of occupants. It encompasses various factors including humidity, ventilation, particulate matter, airborne contaminants, and temperature control. Poor indoor air quality can lead to respiratory issues, allergies, fatigue, and more serious health conditions over time.
In regions like Florida—high humidity levels and warm temperatures can amplify indoor air quality challenges, making it crucial to implement proactive solutions

If your system is over 10–15 years old, requires frequent repairs, or struggles to keep your home comfortable, it might be time for an upgrade.

The best system depends on your home’s size, layout, insulation, and your comfort preferences. Our team provides a free consultation to help you select the most efficient and cost-effective option for your needs.

While you can change filters and clean vents, professional maintenance is essential for inspecting electrical components, refrigerant levels, and ensuring safe, optimal operation.

2. Site Survey and Home Heat Load Calculations

This may be one of the more important stages of the process. All homes are unique in their own way. We put time into ensuring we select the right equipment for your home and that comes from sizing for the right unit. We measure the exterior of the home to include windows, doors, and overhangs as well as note the construction details of your home to confirm make sure the equipment will properly cool and heat the space…we call this conducting a “load calculation” which is recommended whenever installing a new system. We also include all the materials needed to complete the installation and ensure the installation is beyond national building codes and manufacturers’ specifications.

Commercial HVAC systems differ from residential systems in that they consist of many interconnected systems. These systems provide the entirety of a building with heating, cooling, and ventilation.

​The total cost of a commercial HVAC system, including parts and service, can range greatly depending on the equipment needed and the overall size of the system. Commercial HVAC installation may cost anywhere from $7000 to $30000 on average.

Various factors will determine the lifespan of the average commercial HVAC system, such as the quality of the components and how much maintenance it receives. Typically, a commercial HVAC system will have a lifespan of 10 to 15 years.
