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.

First time prospective client of Guthrie and Sons. Very responsive staff in providing updates on my calls. Mario F. came over to check out my existing cooling and heating system and is very thorough and professional in providing necessary information related to repair/upgrades. Pending his quote, my experience with Guthrie and Sons is top notch and most highly recommended.

My experience with Guthrie & Sons has been excellent, and I am pleased to write a very favorable review about it. They replaced three air conditioners and three propane furnaces with new equipment that utilizes heat pump technology. I had met with other companies and I was close to coming to a conclusion, when a friend recommended Guthrie & Sons. He told me that they are hyper focused on customer service from beginning to end.Their customer service started with the on line completion of a basic information form. Shortly after submitting that form, I heard from Zach who scheduled an appointment at my home.I had already met with three other HVAC contractors, and for that reason, I had some basic information about the systems available and how heat pumps work and whether propane furnaces should also be installed. I signed a contract on a Friday. By Wednesday of the next week they had completed the installation. Wow.The installation of one of the furnaces in the attic caused minor damage to the drywall. THEY BROUGHT IT TO MY ATTENTION and told me a drywall contractor would be in touch regarding its repair. Two days later it was repaired.Since installation, the equipment (heat pumps from Bosch) has been working great and I am optimistic about the future. Meanwhile, their pricing, warranty and terms are far superior to their competitors.Since this is an unusually long review and so favorable, let me add this: This is my honest, uncompensated opinion. I have no relationship with anyone at Guthrie & Sons other than the contract we executed.

We recently had Guthrie and Sons install a Mini-Split system in our home. The entire process was handled professionally with no issues occurring at any time. The estimator (Vlad) went through options with us but let us evaluate the best solution for us with zero pressure. The installation team (Matthew and Aaron) showed up on time, reviewed the scope of the job, made sure they understood what we wanted, and then proceeded to complete the installation exactly as discussed. They asked for my input as needed so there were no surprises when the job was completed.They respected my property and made sure everything was left at least as clean was when they arrived. The job was completed on time and as promised and they reviewed the details of the system and its use clearly. I would definitely have Guthrie and Sons do other electrical/HVAC work should the need arise.

I have been in the construction industry in San Diego for over 50 years. I owned my own contracting company for over 40 years. I have seen all levels of customer service in my years. The level of customer service from Guthrie and Son’s is among the best I’ve ever seen and received. Every time I hear anyone asking for a referral for HVAC work I immediately give them your number. When I recommend a company I in essence am putting my name and reputation on the line. I refer them with 100% confidence in the service they will receive. Thank you very much for your legendary service.

We first hired Guthrie and Sons to replace a furnace after comparing proposals from several heating and air companies. They’ve since been back for annual check ups, and today Kareen came to diagnose and resolve an issue with our mini-splits. My experience each time, including today, is that they hire friendly, knowledgeable people who do good work. They’ve never tried to upsell or do anything unnecessary, which is the way it should be. I’d recommend them to anyone who asks.

My AC was not working for seven months. Three other companies tried to fix it with no success. Don’t make the same mistake I did—go straight to Guthrie & Sons! They are absolutely worth every penny.

Jonathon is a great technician. He is very willing to answer any questions and explains things very well. He is very transparent with letting us know cost, finance options, different furnace models and anything else we want to know. I would highly recommend him to anyone looking for furnace repair or replacement.

Guthrie and Sons took on the challenging project of installing an HVAC system at St. George's Serbian Orthodox Church of San Diego, CA. They were the only company among the six we consulted that saw the project through to the end. The members of our congregation are not just happy, but thoroughly satisfied with the heating and air conditioning. The system, split units/floor units with condensers outside, was installed with minimal intrusion onto the church's artwork. Despite the project taking longer than expected due to permit delays, the results were well worth the wait. We highly recommend Guthrie and Sons Heating and Air.

Have been using Guthrie & Sons for several years now and purchase my new HVAC system with them. They do our yearly maintenance and have always been professional, efficient and reliable. Jonathan was the tech that came today and I want to thank him for his great work and great attitude.

Got recommended this company by my boss who had a whole mini split system installed in his house. Was able to schedule a service appt same week. On morning of service Daniel W. shows up, listens to all of my concerns, and gets right to work. Daniel was able to investigate the problem, took his time making sure he's eliminated all other possible issues before coming up with a recommendation to my original proposal. Fixes up the issue then checks to see if it is working properly. Not only that, he stays with me few more minutes and addresses all the questions I had for him regarding the system, as a whole. Absolutely amazing.I'll be calling back to schedule maintenance services with them going forward. They won me as a customer.

Zach was very knowledgeable and flexible. He did not push us to purchase a new furnace and instead came up with a plant to continue monitor the furnace and air condition. The inspection was good and he replaced a battery. Looking forward to work with him in the future

Vlad was very friendly, answered all my questions and gave me information I didn’t know. Would call again for any thing I need.
