Trusted Heating Installation & Replacement

Our heating replacement process involves removing the old unit, reviewing your system options with you, and installing the new heater properly. If you’re not sure which heating system you want, we can help you choose between:

  • Heat pumps: These are a popular choice in San Diego because of their ability to both heat and cool a home.
  • Split systems: These systems have the AC unit outside and the heating unit inside, both connected to your thermostat.
  • Mini-split systems: These are smaller versions of split systems designed for small homes or single rooms.
  • Packaged units: This large unit houses an AC unit and a heater in one space.

Benefits of Installing a New Heating System

Installing a new heating system in your home can be beneficial in many ways. Here are a few perks:

  • You’ll save money on energy bills: A new heating system will be more energy-efficient, meaning it will likely cost you less to run each month.
  • You can get rebates for being eco-friendly: There are various rebates available for new heating equipment installations, and we can help you find the ones you’re eligible for.
  • You’ll avoid constant repairs: A new heating system means you won’t have to deal with constantly repairing your old one.
  • You’ll have a more comfortable home: A new heating system will heat your home more evenly.

Heating Systems We Offer

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

Split
Systems

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

Package
Units

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.

Heating Installation FAQs

Do I need a heating system in San Diego's mild climate?

While the weather doesn’t get as cold as in other parts of the country, having a heater is still recommended. Heaters can help balance the humidity in your home and keep it at a comfortable temperature, especially at night when it’s coldest.

Heat pumps are a popular choice for San Diego homes due to their energy efficiency and size. However, the type of heater you need depends on your home’s size, available space, and other factors.

Yes, installing a new energy-efficient HVAC system can potentially qualify you for various state and federal rebates.

Great experience from my first inquiry setting up a consult, the actual consult, install, and completion. I am completely satisfied with the work performed. I had my 45 year old furnace replaced and AC installed. I will continue to be a G&S customer in the years to come due to the professionalism, customer service, and genuine warmth I experienced. Thank you so much for making the whole process seamless!

Vlad is very easy to work with as he is very straight forward. He worked with me a little on the final quote which I appreciated and seems to understand the space saving features I required. The work still needs to be done and the condo approval process needs to begin but I feel very comfortable.

he double checked everything and discovered that the recent tenting closed the vent on the roof which he then fixed. He is one of the very few service guys who actually services a product w/o trying to sell you something. good man.

Really appreciate our 2 technicians from Guthrie & Sons, Air and Solar! My parents have been served by the company for over 20 years and Guthrie continue to impress with their outstanding understandings of our HVAC system and ability to refresh, repair or replace items to keep system in top shape even though its an older system. Their service contracts are reasonably priced and I know we will get excellent value for the cost. Thank you!

Having trouble with the remote and to operate our mini split cassette unit. Within 5min Mario had the unit up and running as well as how the unit with remote works efficiently. Mario also went to bat for us to have the condenser mounted on the Guest House rather than in the dirt inches away from our brow ditch.Thanks Mario
