Why HVAC Maintenance Matters‒And What You Can Do for Your Heating and Cooling Systems

In a city like Chula Vista—where summers can bring dry heat and winters deliver cool ocean breezes—your HVAC system plays a year-round role in keeping your indoor climate stable.

Financing Options and Other Great Ways to Save on Repairs and New Equipment Costs

We know that needing a major HVAC repair—or finding out you need a full system replacement—can catch you off guard. Not everyone has savings set aside for a new air conditioner or heater, and that’s okay. At Guthrie & Sons, we don’t believe your comfort should be out of reach just because the timing isn’t ideal.

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.

Help With Rebates and Energy Incentives

Many energy-efficient systems qualify for local rebates or federal tax credits. We’ll guide you through what’s available and help handle the details so you can get the savings you’re entitled to.

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.

Air Purifier Repair

If your system stops filtering properly or the airflow drops off, our air purifier repair service will find the problem fast. We replace filters, fix connection issues, and test overall performance so your air stays clean and consistent.

CO Detector Installation

We offer CO detector installation services to help protect your family from carbon monoxide leaks. Our team installs reliable detectors in key areas of your home and makes sure they’re wired or powered correctly for 24/7 monitoring.

Dehumidifier Installation

Chula Vista’s coastal climate can trap moisture indoors. With a whole-house dehumidifier installation, we reduce excess humidity that leads to stuffy air and mold. We size and install systems based on your home’s layout and humidity levels.

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.

Duct Sealing

Leaky ducts not only waste energy but also let dust and pollutants into your living space. With our HVAC duct sealing services, we locate hidden leaks and seal them tightly—improving both air quality and system efficiency.

Media Air Cleaner Installation

Our media air cleaner installation adds another layer of defense against microscopic particles. These high-efficiency filters trap dust, smoke, and even viruses—ideal for homes that want more filtration without sacrificing airflow.

Thermostat Installation

With our smart thermostat installation, you can control temperature, humidity, and system performance from your phone. We install and program units for energy savings and better comfort throughout your home.

Thermostat Repair

If your thermostat doesn’t respond, misreads temperature, or constantly disconnects, our thermostat repair services will restore it. We test wiring, replace sensors, and re-sync settings for consistent control.

Thermostat Replacement

When your old thermostat is old or broken, a thermostat replacement service is the answer. We’ll help you choose a smart, programmable model that boosts both energy efficiency and convenience in your daily life.

UV Air Cleaner Installation

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. At Guthrie & Sons, we install top-quality systems designed to reduce your utility costs without sacrificing comfort. Reach out to get a free estimate for your heat pump water heater installation in Chula Vista.

Solar Services in Chula Vista, CA

Chula Vista sees sunshine nearly year-round, making it an ideal place to invest in solar. With our solar panel installation services, you can turn those sunny days into serious energy savings.

We install premium solar panels at the right angle and placement to maximize output and long-term performance. Some of the top benefits of going solar include:

  • Lower utility bills every month
  • Smaller environmental footprint
  • Increased property value
  • Long-term equipment warranties

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.

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.

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.

Most HVAC systems last 10 to 15 years with proper care. Regular tune-ups can extend that life and help you avoid early replacement.

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.

We could tell you how much we care about doing the job right—but we think our customers say it best.

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.

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.

Got recommended this company by my boss who had a whole mini split system installed in his house. Was able to schedule a service appt same week. On morning of service Daniel W. shows up, listens to all of my concerns, and gets right to work. Daniel was able to investigate the problem, took his time making sure he's eliminated all other possible issues before coming up with a recommendation to my original proposal. Fixes up the issue then checks to see if it is working properly. Not only that, he stays with me few more minutes and addresses all the questions I had for him regarding the system, as a whole. Absolutely amazing.I'll be calling back to schedule maintenance services with them going forward. They won me as a customer.

Zach was very knowledgeable and flexible. He did not push us to purchase a new furnace and instead came up with a plant to continue monitor the furnace and air condition. The inspection was good and he replaced a battery. Looking forward to work with him in the future
