We know that needing a major HVAC repair—or finding out you need a full system replacement—can catch you off guard.

Our team is here to help you find a solution that fits your budget. From flexible financing plans to helping you take advantage of available rebates and tax credits, we’ll walk you through the options and make the process simple.
HVAC Financing That Works for You
Whether you’re installing a brand-new cooling system, upgrading a furnace, or switching to ductless, we can help you get the equipment you need now and pay over time.

Heating and Cooling Services in Chula Vista, CA
Summers here are warm and dry, and while winters are mild, coastal evenings can cool off quickly. If you’re running the AC all day or flipping on the heat at night, your system needs to be ready.

Whether you’re installing central air for the first time or need help with maintenance or repairs, Guthrie & Sons has the air conditioning services in Chula Vista, CA, that keep your home cool. We install, service, maintain, and replace central air conditioning systems across the local area.
Air Conditioning Installation
A proper central air conditioning installation starts with understanding your home’s airflow and layout. We perform detailed load calculations, inspect existing ductwork, and recommend energy-efficient systems that won’t just cool your house—they’ll cool it evenly, quietly, and affordably.
Air Conditioning Maintenance
Maintenance is the difference between reliable comfort and a mid-summer breakdown. We provide full-service central air conditioning maintenance, including deep coil cleanings, drainage checks to prevent leaks, and airflow testing to catch duct issues early.
Air Conditioning Repair
When a central AC unit starts short cycling, rattling, or losing its cooling power, we don’t guess—we diagnose. Our air conditioning repair process includes testing refrigerant levels, inspecting capacitors and contactors, and checking pressure across coils and valves. We come prepared to solve the problem on the spot so you can get back to a cool home fast.
Air Conditioning Replacement
Sometimes, the smartest fix is a full upgrade. If your system needs constant repairs, uses outdated refrigerant, or can’t meet today’s energy standards, we offer central air conditioning replacement with newer, high-efficiency models that qualify for rebates. We remove your old system, install the new one, and ensure it’s calibrated for comfort from day one.
Mini Split Services
You’ve probably seen a ductless mini split system in a home or business before. These systems are sleek, compact, and ideal for zoned heating and cooling in buildings where ductwork isn’t wanted or practical. At Guthrie & Sons, we provide expert ductless mini split services in Chula Vista, from installation to replacement.
Mini Split Installation
Installing a ductless mini split requires the right planning and placement. We mount indoor air handlers on walls or ceilings where they’ll deliver targeted comfort—often in spaces like garages, guest suites, or add-ons where ducts don’t reach. We’ll help you pick a model that fits your needs and make sure everything is set up for long-term performance.
Mini Split Maintenance
Mini splits in Chula Vista need regular upkeep due to coastal air and long cooling seasons. We recommend bi-annual service to clean washable filters, flush the condensate line, inspect electrical components, and check refrigerant pressure. Our ductless mini split maintenance helps prevent moisture buildup, airflow problems, and unexpected shutdowns.
Mini Split Repair
If your mini split is leaking, making clicking sounds, or flashing an error code, our ductless mini split repair service can help. We identify the source—whether it’s a failed sensor, blocked drain line, or low refrigerant—and fix it fast.
Mini Split Replacement
When repairs become too frequent or the system just doesn’t keep up, a ductless mini split replacement is often the better investment. We’ll inspect your current setup, explain your options, and install a modern, high-efficiency model that’s better suited to your space.
Heat Pump Services
Heating and cooling don’t always require a heat source or coolant. Heat pumps move heat from inside your home to the outside for cooling and vice versa for heating. These energy-efficient systems replace the need for a furnace and air conditioner.
Guthrie & Sons offers full-service heat pump services in Chula Vista, including expert installation, reliable repairs, scheduled maintenance, and energy-saving replacements.
Heat Pump Installation
We install heat pumps in homes of all sizes, whether it’s a retrofit or part of a new build. Our heat pump installation service includes load calculations, thermostat integration, and full system testing to ensure balanced airflow and efficient year-round performance.
Heat Pump Maintenance
With year-round use, heat pumps in Chula Vista benefit from twice-annual tune-ups. Our heat pump maintenance includes checking reversing valves, defrost controls, and refrigerant levels, plus coil cleaning and motor lubrication to extend system life and improve efficiency.
Heat Pump Repair
Unusual noises, uneven temperatures, or short cycling can all signal a need for heat pump repair. We troubleshoot fast and fix problems like compressor failure, sensor errors, or defrost issues to restore comfort without delay.
Heat Pump Replacement
If your system is outdated or no longer efficient, our heat pump replacement service makes upgrading easy. We remove the old unit, help you select an ENERGY STAR®-rated model, and expertly install it to lower utility bills and boost comfort.
HVAC Services
Your HVAC system does more than just control the temperature—it helps maintain air quality, control humidity, and balance airflow throughout your home. Whether you rely on a heat pump, a central air conditioner, or a combined heating and cooling setup, Guthrie & Sons delivers complete HVAC services in Chula Vista tailored to our region’s coastal conditions.
HVAC Installation
Installing a new HVAC system starts with understanding your home’s layout, insulation, and ventilation. We design systems that support balanced indoor climate control, size equipment for optimal SEER ratings, and install every component—including ductwork, thermostats, and zoning controls—with expert precision.
HVAC Maintenance
Twice-yearly HVAC maintenance helps prevent common issues like clogged filters, poor airflow, and electrical failure. Our service includes a full inspection, coil cleaning, airflow testing, and checking all safety and control systems—perfect for homes facing salt air and long AC seasons like in Chula Vista.
HVAC Repair
When your HVAC system makes loud noises, creates hot and cold spots, or suddenly stops working, we’re on it. Our HVAC repair service includes pinpoint diagnostics, replacement of worn parts, and real-time performance testing so your home gets back to being comfortable quickly and reliably.
HVAC Replacement
If your energy bills are creeping up or your HVAC system is more than 12–15 years old, it may be time to consider an HVAC replacement. We remove outdated units, evaluate your home’s needs, and install newer, energy-efficient models that deliver better performance with lower monthly costs.
Heating Services
Even in a mild climate like Chula Vista, there are plenty of chilly mornings and breezy nights when a dependable heating system makes all the difference. At Guthrie & Sons, we provide heating services in Chula Vista for every type of home setup—whether you rely on a traditional gas furnace, ductless system, or heat pump.
Heating Installation
A good heating installation begins with choosing the right system for your home’s layout and usage patterns. We’ll assess everything from insulation levels to room size and ventilation flow to recommend a heating unit—whether it’s a furnace, heat pump, or ductless system—that’s energy-efficient and properly sized for your space.
Heating Maintenance
Heating maintenance isn’t just about tuning things up—it’s about protecting your investment. Our detailed inspections include airflow testing, control calibration, and cleaning out buildup that naturally collects in Southern California homes. With annual heating maintenance, you’ll avoid emergency breakdowns and enjoy quieter, more efficient operation when chilly nights set in.
Heating Repair
Heating repair calls often start with one of three signs: no warm air, strange noises, or a system that just won’t respond. When that happens, our technicians come equipped to diagnose the issue quickly. From worn-out sensors to airflow obstructions, we get to the root of the problem fast and get your system running again.
Heating Replacement
Sometimes, the clearest sign you need a heating replacement isn’t a breakdown—it’s rising utility bills, uneven temperatures, or a system that just can’t keep up with cooler nights. We’ll assess your current setup and help you transition to a more efficient model that aligns with your energy goals and comfort needs.
Furnace Services
When the temperature drops in Chula Vista, even a little warmth goes a long way. While our coastal climate is mild, crisp mornings and chilly evenings make a dependable furnace feel like a luxury. At Guthrie & Sons, we offer professional furnace services in Chula Vista at a price that fits your budget.
Furnace Installation
Choosing between a gas or electric furnace? We’ll help you weigh the pros and cons. Gas furnaces heat faster and tend to be more cost-effective over time, while electric models offer cleaner operation and are easier to install in homes without natural gas.
Furnace Maintenance
With California’s moderate winters, we recommend furnace maintenance once a year—usually in early fall. Our service includes inspecting the burner assembly, tightening loose electrical connections, replacing dirty filters, and verifying that the thermostat communicates with your system properly. Routine care like this helps reduce wear and keeps heating costs low.
Furnace Repair
Common furnace problems in Chula Vista include pilot light issues, faulty ignition systems, and airflow restrictions caused by dirty filters or worn blower components. Our furnace repair service addresses these issues head-on with accurate diagnostics and quick fixes—so you’re never left shivering when the temperature drops.
Furnace Replacement
When you need to replace your furnace, we’ll assess the condition of your current unit, walk you through energy-efficient upgrade options, and install a new system that’s built to perform. By staying on top of maintenance, we can help you anticipate when a furnace replacement is needed—so you’re never caught off guard.
Indoor Air Quality Services in Chula Vista, CA
Even in coastal Chula Vista, where ocean breezes help keep things fresh outdoors, the air inside your home can tell a different story. Everyday living adds dust, dander, pollen, and even humidity to your indoor space. Many factors impact how healthy your indoor air really is.
That’s why Guthrie & Sons offers a wide range of indoor air quality services in Chula Vista that give you better control over your home’s climate.
Air Purifier Installation
A whole-home air purifier installation connects directly to your HVAC system to capture airborne particles before they circulate. These systems reduce allergens, bacteria, and odors—making them a great choice for families with allergies, pets, or anyone sensitive to poor air quality.

Dehumidifier Repair
From faulty drain pumps to inconsistent moisture readings, our dehumidifier repair services get your system back on track. We inspect internal parts, calibrate sensors, and ensure your space stays dry and balanced.

A UV air cleaner installation targets airborne germs and mold that filters can’t catch. These systems use ultraviolet light inside your HVAC system to neutralize pathogens before they enter your living space.
UV Light Installation
We provide HVAC UV light installation near coils and ductwork to keep your system cleaner and air healthier. It’s a proactive way to reduce biofilm, mold growth, and maintenance costs long-term.
Heat Pump Water Heater Services in Chula Vista, CA
Every home needs reliable hot water, but running a traditional water heater can quickly drive up your energy bills. That’s where heat pump water heaters shine. These systems pull heat from the air around them to warm your water, making them much more energy-efficient than models that rely solely on gas or electric heating elements.
With our local weather, heat pump water heaters perform especially well—delivering dependable hot water while using far less energy.

Frequently Asked Questions
What else should I look for when buying a mini split?
Pay attention to the SEER (Seasonal Energy Efficiency Ratio) rating, noise level, and how many zones the system supports. We’ll help you choose one that fits your space, comfort goals, and energy efficiency needs.
How do I know if my heater is bad?
If it’s blowing cool air, making loud noises, or your energy bills are rising unexpectedly, something’s off. We can inspect it and let you know if a repair or replacement makes more sense.
Why get a maintenance plan for your HVAC system?
A maintenance plan keeps your system running efficiently and helps prevent surprise breakdowns. You’ll also get priority service and savings on repairs throughout the year.
How many years should an HVAC system last?
Most HVAC systems last 10 to 15 years with proper care. Regular tune-ups can extend that life and help you avoid early replacement.
What is the best heating and cooling system for a small house?
Ductless mini splits or high-efficiency heat pumps are great options for small homes. They offer zoned comfort and lower energy use and don’t require bulky ductwork.
