Heating and Cooling Services in Poway, CA

In Poway, HVAC systems work hard for most of the year—especially during dry, sunny summers and crisp, cool winter nights. With up to 9 months of active usage, reliable heating and cooling isn’t optional—it’s essential. Whether you’re trying to beat the heat or stay warm indoors, Guthrie & Sons provides heating and air conditioning services in Poway designed to keep your indoor climate control on point year-round.

Air Conditioning Services

With dry inland heat and long cooling seasons, central air conditioners are a popular choice for homes in Poway. But dust buildup, long run times, and system age can shorten the life of your AC. That’s why we offer complete air conditioning services in Poway—from expert installs to dependable repairs and preventive maintenance.

Air Conditioning Installation

Every home is different, so we don’t believe in one-size-fits-all air conditioning installation. We help you choose an air conditioner that matches your home’s size, layout, and energy goals. Our team installs top-rated cooling systems with precision for long-term performance.

Air Conditioning Maintenance

Preventive air conditioning maintenance helps you avoid major breakdowns when you need your system most. Our thorough service includes coil cleaning, filter changes, and checking for any cooling system wear or airflow issues.

Air Conditioning Repair

Warm air, weak airflow, or strange noises? These are signs you may need air conditioning repair. We quickly pinpoint issues—whether it’s a faulty sensor, clogged filter, or refrigerant problem—and get your cool air back without unnecessary delays.

Air Conditioning Replacement

Older air conditioning units lose efficiency and drive up your energy bills. If your system is 10+ years old or breaks down frequently, we recommend a full air conditioning replacement. We’ll help you pick a cooling solution that improves comfort and lowers operating costs.

Mini Split Services

A ductless mini split is a flexible heating and cooling system that uses an outdoor unit and one or more indoor air handlers to provide targeted temperature control. You can choose from cooling-only systems or heat pump mini splits that both heat and cool. They're efficient, easy to control, and don’t require ductwork. At Guthrie & Sons, we offer full ductless mini split services in Poway, including installation, maintenance, repair, and replacement.

Mini Split Installation

Our mini split installation service is perfect for spaces like garages, additions, or any room without ducts. We install both single-zone and multi-zone units for custom indoor climate control. Enjoy quiet operation, zoning flexibility, and reliable home cooling or home heating year-round.

Mini Split Maintenance

Regular mini split maintenance is key to keeping your system running at peak efficiency. We clean filters, check refrigerant levels, flush drain lines, and inspect electrical connections. Twice-a-year tune-ups help extend the lifespan of your heating and cooling system.

Mini Split Repair

Is your system making strange noises, not responding to the remote, or dripping water? Our mini split repair service handles common issues like faulty sensors, clogged filters, and communication errors. We diagnose the problem fast and restore your heating and cooling.

Mini Split Replacement

If your system is over 12 years old or can’t keep up with your temperature regulation needs, it might be time for a mini split replacement. We’ll evaluate your space, recommend energy-efficient options, and install a new ductless cooling or heat pump unit.

Heat Pump Services

Heat pumps are a smart, all-in-one solution for heating and cooling your home. Instead of creating heat, they transfer heat energy, moving warmth out of your house to cool it and pulling warmth in to heat it. At Guthrie & Sons, we provide full heat pump services in Poway, including installation, maintenance, repair, and replacement. If you're ready to ditch the gas furnace or old AC, take advantage of rebates and tax credits and make the switch to a heat pump system today.

Heat Pump Installation

Our heat pump installation services start with a load calculation to size your system correctly. We install both air-source and ductless heat pumps, integrating them with your existing HVAC system or setting up a brand-new one. You’ll get year-round comfort and better temperature control without relying on gas.

Heat Pump Maintenance

Twice-a-year heat pump maintenance helps prevent breakdowns and keeps your system energy-efficient. Our tune-ups include checking the reversing valve, cleaning indoor and outdoor coils, testing refrigerant levels, and verifying that your climate control system switches modes smoothly from heat to cool.

Heat Pump Repair

If your system won’t switch modes, makes strange noises, or your home isn’t holding temperature, you might need heat pump repair. We diagnose compressor issues, fix sensor malfunctions, and resolve air handler problems quickly.

Heat Pump Replacement

Older units lose efficiency and may no longer qualify for energy efficiency rebates. If repairs are stacking up, our heat pump replacement service helps you upgrade to a more efficient model. We’ll walk you through the process, remove the old unit, and install a reliable, modern system designed to lower bills and improve comfort.

At Guthrie & Sons, we offer full-service HVAC services in Poway that keep your indoor climate comfortable and efficient year-round. From custom installs to emergency repairs, we specialize in heating and cooling systems that match your lifestyle and home setup.

From air conditioning units to furnaces and smart thermostats, we’ll install a system that’s built to last and perform.

HVAC Maintenance

Routine HVAC maintenance keeps your comfort consistent while reducing wear and tear.

Whether it’s spring tune-ups for your AC or fall service for your furnace, we help prevent problems before they start.

HVAC Repair

When your system struggles to heat and cool evenly or starts making unusual noises, call our team for fast HVAC repair. We diagnose faulty components like capacitors, relays, or blower motors and restore performance with long-lasting fixes. Our goal is to get your heating and cooling back online as quickly as possible.

HVAC Replacement

If your current HVAC system is more than a decade old, inefficient, or costing you too much in repairs, you may be due for an HVAC replacement. We’ll help you select a modern unit that meets your home’s thermal control needs, qualify for rebates, and boost your energy efficiency without overpaying on utilities.

Heating Services

When winter mornings get brisk or coastal nights turn cool, your home needs more than just a blanket. It needs a reliable heating system that keeps every room consistently warm. At Guthrie & Sons, we provide expert heating services in Poway for homes with heat pumps, furnaces, or ductless heating systems.

Heating Installation

Getting the right heat starts with the right system. Our heating installation service takes into account your home’s layout, insulation, and airflow to recommend options like furnaces, heat pumps, or ductless systems. Whether you need a whole new system or just want to replace outdated equipment, we’ll install it cleanly, efficiently, and to code.

Heating Maintenance

Think of heating maintenance as the routine your system needs to stay strong. We fine-tune your heating and cooling equipment for better temperature regulation, check for wear and tear, clean internal components, and make sure everything runs safely. One annual visit can prevent costly issues and keep your energy bills in check.

Heating Repair

When your home doesn’t feel quite right, chances are your heating system is trying to tell you something. Uneven temps, cold air, or strange noises? We’ve seen it all. Our heating repair team is quick to diagnose the problem and get your system back in working order.

Heating Replacement

If your current unit is older, unreliable, or just not heating the way it used to, it may be time for a heating replacement. We help you find the right match for your space and energy goals—whether it’s an advanced heat pump or a modern furnace—so your home stays warm when it counts.

Furnace Services

Poway may not see snow, but those chilly nights and cool mornings still call for a reliable source of heat.

Furnace Maintenance

Even in a mild climate, furnaces need annual attention. Our furnace maintenance service helps reduce wear, extend system life, and optimize your temperature control. We inspect burners, clean components, check safety switches, and make sure your heating system is ready before the first chill hits.

Furnace Repair

Sometimes your furnace doesn’t quit completely—it just makes life uncomfortable. Maybe one room stays cold, the system turns off too soon, or it’s running nonstop without really heating. Our furnace repair service gets to the bottom of those frustrating issues fast.

Furnace Replacement

Most furnaces don’t go out with a bang—they just get less efficient over time. If your energy bills are creeping up or your furnace needs frequent repairs, it might be time for a furnace replacement. We’ll inspect your current system and give you a clear picture of how much longer it can go. When it’s time, we help you upgrade to a new heating system.

Last summer my air conditioner couldn't cool the house in the hottest period of summer. The HVAC team I was working with came in and said the coils were leaking, the unit was 20 years old. I requested quotes from 5 different companies, and the variation of prices was huge. I went with Guthrie and Sons for these reasons:1. Local Company2. Family Owned3. Great presentation, no pressure4. Good products5. Competitive pricingJust installed yesterday, so jury is still out on the system, but installation was thorough and great communication so far!

Carson and Michael were brilliant. The heat pump installation went smoothly, and they are really pleasant and trustworthy fellows. The day after it was installed, I had a plumber at my house. He looked at their work and was impressed. He said it was much cleaner than the way HVAC people usually do it.

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.Updated review: Kareen, Daniel and Michael worked on the AC replacement, relocation of furnace to the attic and replacement of ductwork. Very professional and knowledgeable team in my opinion. Completed the work in a timely and very satisfactory manner.

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.

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.
