System Sizing


System Sizing in San Diego, California

When shopping what size HVAC unit you should buy, what matters the most is what size house you have and what your desired temperature range is that you want to maintain throughout. Knowing how many BTUs are required for your home will allow you to make the best decision what size HVAC system you should purchase.


There are two types of HVAC systems, single stage and two-stage. Single stage units are what you want for your home if your desired temperature does not go far above what the normal setting is set to during summer or winter. Two-stage units are what you should get if there are times where the temperature gets much hotter or cooler than this baseline temperature.


At SonRise Mechanical we will determine the proper system size for you through manual calculation or square footage measurements and recommend the best option.
