Commercial Heating System Installation

Whether your business needs a single heating system replaced or you need multiple heating system replacements, our certified technicians have you covered. 

Heating Systems We Offer

Whether you’re looking for a traditional split system, a high-efficiency heat pump system, an “all-in-one” package unit, or a mini split system with individual climate control, Guthrie & Sons has a heating solution for you. View our heating systems below.


A traditional heating and air system consists of one indoor unit, which is your furnace or heater, and one outdoor unit, your air conditioning condenser. 

Heat Pump Systems

Heat pump systems are becoming increasingly popular. Considering most San Diego homes now have solar, a heat pump system is the perfect solution as it can run on electricity, not natural gas.


Package units are an “all-in-one” solution where the heating and cooling elements are combined into one single unit. Ideal for when you want to save interior space as no furnace is needed. 

Mini Split Systems

Depending on your home, you may not be able to install ductwork which is necessary for directing airflow. With mini splits, you can install a unit in any room, allowing you to individually control the temperature.

The prompt only allowed me to choose one option. But the whole team was professional, helpful, on time, and provided me with all the information I needed on the quality products that were installed.

I’ve been with Guthrie & Sons since 2008. They installed my new unit and have serviced it twice a year ever since. Something has changed and not for the better. Most notable in communication. After a service visit I received several quotes for further work, mind you no call made during the visit to notify me of these items. New quotes also include a $95 visit fee! If I’m already paying for the initial visit why would you leave without speaking to me if more work was recommended? I called the number on the email that specifically said “if you have questions”. Needless to say the person who answered “Amy” couldn’t provide one single thing of information regarding my visit and I have to speak to the technician. She was politely dismissive and just kept referring me to the technician. This isn’t the level of service I’ve had in the past and not sure I can stay if this is the new standard.

They offered a very competitive price for a much higher SEER unit and they were efficient, clean and informative completing the removal and install of the new unit in one day. I am also very happy with the Bosh unit they recommended and installed.
