Professional Heating Load Calculation

If you’ve never purchased a new heating system before, you might not know how important it is to get an accurate heating load calculation before you even begin shopping for new models. After all, knowing how much heating power your system needs is an important part of narrowing down your choices and choosing the right system.

Our team of heating installation professionals use industry standards to assess your home’s heating needs and calculate the heating load accurately. To do this, we consider the square footage of your home, the layout and placement of rooms, the number of windows in your home, and the level of insulation throughout your home.

Complete Heating System Lineup

Once we’ve determined your home’s heating load, we can help you compare and contrast your many heating system options. Whether you want a system with the highest possible heating seasonal performance factor (HSPF) rating, the newest technical features, or the most straightforward integration with a whole-home control system, we’ll zero in on the ideal heating system for you.

We service all makes, models and brands. Want an energy-efficient furnace that will keep your family warm and cozy all winter long? We have just the electric, gas or oil model you need. Prefer a heat pump that can warm you up in the winter and switch over to cooling mode in the summer? We have a range of efficient, high-tech options to consider.

Seeking a packaged system that prioritizes efficiency but can amp up the heating power when necessary? Our heating service technicians can walk you through your options and ensure that you choose the one that best meets your needs. Want to go green with a geothermal heat pump? We’ll help you optimize efficiency and make your household’s carbon footprint as small as possible.

Fast, Easy Heating Installation

After we’ve worked with you to identify the ideal heating system for your home, we’ll walk you through the installation process. Before we begin replacing your old system or installing the new one, you’ll understand the complete project timeline. We’ll streamline as much as possible, as we know you’re eagerly anticipating relaxing in your newly cozy home.

That’s not all, though. Throughout the process, our experienced team of heating technicians will help you view heating installation as a valuable investment for your home rather than just another household expense. Choosing the right furnace, boiler or heat pump means your family will be safe and warm for years to come. The right system may even increase your home’s value.
