Expert Air Conditioning Services in San Diego, CA

San Diego County is known for its pleasant climate, with moderate to high humidity levels the closer you get to the coast. While we enjoy mostly ideal weather, maintaining your AC is essential to ensure year-round comfort. Air conditioning regulates indoor temperature, humidity, air quality, and air circulation, all vital components to whole-home HVAC.

Guthrie & Sons Heating, Air & Solar provides top-rated AC repair, installation, and maintenance in San Ysidro and Oceanside. Our NATE-certified technicians deliver consistent care, including free estimates on AC replacements.

Trust the local experts in cooling and heating. If your home needs an emergency AC repair or a cooling installation, contact us to schedule an appointment.

Air Conditioning Repair

Even with proper maintenance, air conditioners may face unexpected breakdowns or worn-out components from frequent use.

Our comprehensive AC repairs address common air conditioning issues like short-cycling, noisy operation, refrigerant leaks, or clogged air filters. If you notice any of these signs, schedule a professional repair immediately:

  • Higher energy bills: If your thermostat settings haven’t changed but you can’t say the same about your utility bills, you may have an inefficiency that needs inspection.
  • Uneven temperatures: Hot spots or cold drafts often signal a problem with your ductwork or ventilation.
  • No cool air: If your AC isn’t producing cool air, a faulty compressor or low refrigerant levels may be to blame.
  • Strange sounds or smells: Grinding, squealing, or burnt, plasticky odors require immediate attention.

Air Conditioning Installation & Replacement

We offer various cooling solutions to suit various capacities and budgets. Whether you need a new air conditioner installed or an older system replaced, we’ve got you covered. Our thorough installation process includes a home assessment, assistance in selecting a new unit, removing old equipment, and completing system replacement.

We’ll help you choose the right AC from our full-service options:

  • Central AC: Central air conditioning evenly distributes cooled air throughout your home via ventilation and ductwork.
  • Ductless mini-splits: Ductless systems provide targeted, zoned cooling while taking up minimal space and using less energy.
  • Heat pumps: This energy-efficient alternative is popular in San Diego because of its dual heating/cooling function.

Air Conditioning Maintenance

Prioritizing AC maintenance will prevent costly repairs and combat the effects of wear and tear, especially in units that are 15 years or older. We recommend homeowners schedule an AC tune-up in the late winter or early spring, right before the warmest months when you’ll rely on your AC the most.

Our AC maintenance prolongs the lifespan of your system with critical maintenance tasks like:

  • Outdoor coil cleaning
  • Drain line testing
  • Thermostat operation check
  • Refrigerant level check
  • Discharge pressure inspection

A huge shout out to Zach Mendoza and Guthrie & Sons! I called Guthrie yesterday when our heat failed to work. They were able to arrange an appointment for this afternoon. Zach arrived on time, diagnosed the issue and quickly resolved the problem. He is very friendly, courteous, and knowledgeable. I highly recommend him and his company.

This review pertains to the process in receiving a quote for a HVAC system for a residential dwelling. We welcomed Anthony A. to discuss the potential renewal of our HVAC system. We were in the phase where one seeks different quotes and gain a better understanding of the various options available. Anthony was articulate, explained the options with the pro’s and con’s of each option. He was very professional and personable in getting to know our needs.We will certainly keep his proposal in consideration when we make our decision.Lastly, the appointment process was seem less and punctual.

I've had an ongoing issue with my HVAC not working properly. Two other professionals came by and said I needed expensive upgrades, without fixing the issue. Zach Mendoza from Guthrie & Sons finally fixed the issue. He was polite, knowledgeable and able to fix the issue within minutes without trying to up-sell me. I have confidence that they can do the job.

The time came for us to replace our 20+ year old AC and heater and the overwhelming search for the right company to hire began. I met with 8 companies and after meeting Vlad I just knew I had found the company to hire. Vlad was professional and honest. He never tried to upsell us and was very thorough in explaining all of our options. He simply explained the pros and cons of each system and left the decision to us. The one thing I learned after doing all of my HVAC research is not to focus on the price although G&S was the very competitive. But instead focus on the company you feel will do the best installation. The way G&S provided a detailed interactive proposal breaking down all the work that will be done really put my mind at ease. We have our install scheduled for next week so that will be the true test. I will be updating this review after the installation is done but I can say that I feel very confident they will go above and beyond to ensure the job is done right!

We decided to get central air conditioning after the last 2 summers. After getting quotes from 3 HVAC companies, we decided on G&S. They installed our heater a couple of years ago and did a great job. This time was no different. They showed up promptly, took care to cover the floors, and got right to work. There were 3 installers; Blake, Adam, and Luke ( I think I got the names right!) They each had a job to do and went about it very professionally and with great attitudes. They finished and cleaned up. It was a great experience. I recommend giving G&S a try when looking for heating or AC.
