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

Anthony was very professional and communicative. He was easy to work with in setting up my hear pump installation project. I really appreciated the fact that he wasn't pushing a "hard sell" as some representatives from other companies did. When I had questions an needed quote options he was super-responsive and helpful. Great experience!When Carson, Isaiah, and Israel came your to perform the work, they were punctual, friendly, and respectful. When I expressed concerns or had questions, they addressed them immediately and effectively. Their work was outstanding, the job looks great and the system works well. I have already recommended Guthrie & Sons to other people.Thanks, again, for everything.

We’ve worked with a few Heating and Air company’s in the past at this was far and away the best we’ve worked with. The technician was very professional and friendly, quick with the work but took his time to explain and answer questions. Reasonable pricing and was impress how organized the whole process was. Hands down the best experience with any company in this field!

Good Service. Zach has been here before and we are grateful for his exceptional customer service! He ensures that every piece of equipment is thoroughly checked in the attic and working. Zach wiped down the access door and it is spotless. I appreciate his friendliness and superior service!

The removal of the old direct Heating and ducting went without a hitch. The installation of the new air conditioning and heating unit went very smoothly and I was impressed with every one of the workers. They were friendly and very knowledgeable. They were well equipped to deal with any process problems. I give five stars for this group.As part of the installation contract, Guthrie and Sons sent a worker named Wayne to replace the filter and check our air conditioning condenser. He was friendly and knowledgeable and even slipped on the covers over his shoes as he came through the house. The work was performed very quickly. Another five star performance by Guthrie and Sons.Zack visited today for yearly maintenance. Filter changed out and the unit is working optimally. We'll done.Daniel, this morning, replaced the filter and verified the furnace is in working order and providing proper heat throughout our home. Another skilled and friendly 5 star visit.

Your technician, Jonathan Santana was awesome. My husband was not home and Jonathan was very understanding. Even though there was a mix up with the service connection from Rheem, Jonathan assisted without hesitation. His help made my follow up conversation with Rheem much more productive. Please thank Jonathan for me.Best regards, Lisa
