Frequently Asked Questions

How important is it to get the right size of heating and cooling equipment?

Sizing HVAC equipment is very important from the standpoints of both comfort and energy use. Heating and cooling equipment that is over-capacity will not run as frequently or as long as it does run. In both cases, this may mean poor humidity control. It could also result in temperature variations or noticeable cycling. Over-capacity equipment will not be as energy efficient as properly matched capacity either. On the other hand, undersized equipment will result in a loss of comfort during temperature extremes.

What size HVAC system should I have?

Determining the ideal size of an HVAC system for your home isn’t a one-size-fits-all process. Depending on your home’s construction, one ton of air conditioning can effectively cool anywhere between 300 to 800 square feet. To ensure your system is properly sized to heat or cool your home efficiently—without being larger than necessary—you’ll need an expert evaluation. At National Refrigeration LLC, our licensed professionals offer free, detailed in-home energy assessments to recommend systems that perfectly match your home’s requirements and budget.

How do I know if my AC unit is big enough?

Bigger isn’t always better; what truly matters is performance and efficiency. Before purchasing a new HVAC system, it’s essential to ensure it’s properly sized to meet your specific needs and budget. At National Refrigeration LLC, our specialists will conduct a comprehensive assessment of your home and comfort requirements to determine the ideal system size and make the best recommendation for your situation.

Is a system with more capacity better?

No, a larger heating system with more capacity doesn’t equal better comfort—it actually delivers less and costs more to operate. Air conditioners are least efficient when they first turn on, and a system that’s too large will run in short, frequent cycles, reducing efficiency. Additionally, air conditioners remove humidity only while running, so shorter cycles won’t effectively dehumidify your home. Ensuring the right system size is crucial for both comfort and efficiency, and that’s where National Refrigeration LLC can help with expert guidance.

Mathew Tovar

I’m thrilled with my recent experience with National Refrigeration where I had a 10 Gallon LP Propane water heater installed. This unit is simply phenomenal, delivering ample hot water while running smoothly and efficiently. I would like to extend my gratitude to Jose Luna who was instrumental throughout this process.

Lucio Pena

I honestly can’t put into words explaining how much these people took care of my HVAC needs/problems. After dealing with other companies that were overcharging and providing terrible work, I found National Refrigeration. They provided me the best price I could find and sent out some of the best technicians for the job.
