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.

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.

At Guthrie & Sons, we provide expert heating services in Poway for homes with heat pumps, furnaces, or ductless heating systems.

Getting the right heat starts with the right system.

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.

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.
