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

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

I had a very good experience with them installing a heat pump to complement our gas furnace. Vlad, the project manager, did the initial site review and inspected the existing setup in detail. He made sure that all our concerns about the project as well as about the current system were addressed (we did not have an AC before so it was a more complicated install). Price was comparable to other quotes we got -- but the proposed systems were closer to what we actually wanted. We even got a post-season promotion so the choice was easy.Kareem and his install crew were also great -- he told me in detail what they were going to do and answered all my questions about where and how things are going to go. They were working hard all day to finish the project and making sure everything was cleaned up at the end.Highly recommend!
