Get More Life Out of Your Heating System By Scheduling Maintenance With Us

Most people don’t think about their heating system until it gives them a reason to. By then, the house is cold and the problem usually costs more than it should have. Regular heating maintenance helps catch those issues earlier—when they’re smaller, easier to fix, and less disruptive. It’s about keeping your system in good shape so it’s ready when cooler weather shows up, not scrambling when it doesn’t.

Our USA Membership Plan is built for exactly that. We schedule your yearly tune-up, remind you when it’s time, and make sure you get priority if you ever need service. Members also receive discounted repairs and lower service fees. It’s an easy way to stay ahead of heating problems and keep your home comfortable without the last-minute stress.

Heat pumps are a popular choice in North Park because they handle both heating and cooling without taking up much space or driving up energy bills. One system does the work of two, which makes them a good fit for many homes in the area.

At Guthrie & Sons, we provide full heat pump services in North Park, including installation, maintenance, repair, and replacement. Our technicians have extensive experience with heat pump systems and work on all makes and models.

A heat pump installation in North Park starts with getting the size right. We look at your home’s layout, insulation, ductwork, and airflow before recommending a system. When a heat pump is installed correctly, it keeps your home comfortable year-round without constantly running or wasting energy.

Since heat pumps run in both summer and winter, regular heat pump maintenance in North Park is important. During a tune-up, we clean coils, check refrigerant levels, inspect electrical connections, test the reversing valve, and make sure airflow is where it should be. This helps reduce wear on the system and keeps efficiency from slipping over time.

If your system struggles to keep temperatures steady, turns on and off frequently, or starts making unfamiliar noises, it may be time for a heat pump repair in North Park. Common issues include airflow restrictions, refrigerant problems, sensor issues, or electrical wear. We inspect the full system, explain what’s causing the problem, and walk through repair options before moving forward.

When repairs start adding up or performance drops, a heat pump replacement in North Park may make more sense. Most heat pumps last about 10 to 15 years, depending on use and maintenance. When replacement is needed, we remove the old unit, check existing line sets and electrical connections, and install the new system to manufacturer standards so it’s ready to run properly from day one.

Furnace Services

Furnace Services

Many North Park homes rely on furnaces, especially during those cooler nights when the temperature drops fast after sunset. From original Craftsman and bungalow homes to updated remodels with newer systems, furnaces remain a dependable way to heat the whole house quickly and evenly.

Guthrie & Sons provides furnace services in North Park for both gas and electric systems. Whether your furnace needs repair, routine maintenance, or it’s time to plan for a replacement, we’ll help you sort it out and get your home feeling comfortable again.

Installing a furnace in a North Park home isn’t one-size-fits-all. Some houses have original ductwork, others have additions or remodels that change how air flows. During your North Park furnace installation, we design the system around those details so heat reaches every room without short cycling or hot and cold spots.

Furnaces don’t need constant attention, but they do need to be checked regularly. Our furnace maintenance in North Park focuses on safety and performance. We clean components that collect dust, replace filters, test ignition and safety controls, and make sure the system is operating the way it should before colder weather sets in.

If the house isn’t warming up, the furnace sounds different than usual, or airflow feels weak at the vents, something isn’t right. Our furnace repair in North Park covers common problems like ignition failures, worn parts, airflow issues, and electrical faults. We inspect the system, find the cause of the problem, and fix it so your heat works again.

There’s a point where repairs stop being practical. If your furnace needs frequent service, struggles to keep the house warm, or is near the end of its life, replacement may be the better option. Most furnaces last around 15 to 20 years, depending on how they’re used and maintained. When you need a furnace replacement in North Park, we’ll help you choose the right system and install it properly.

Ductless Mini Split Services

Ductless Mini Split Services

Ductless mini splits are a common solution in North Park when a home doesn’t have ductwork or when certain rooms just never feel right with the main system. They’re especially useful in older homes, remodels, and spaces added long after the original build.

Thinking about adding comfort to a garage conversion, ADU, or back room? Or need service for a ductless system you already have? We provide complete ductless mini split services in North Park to help keep every part of your home comfortable.

A ductless mini split installation in North Park adds heating and cooling without tearing into walls or running ducts. Each indoor unit connects to an outdoor system through a small line set that carries refrigerant and power. We regularly install ductless systems in converted garages, ADUs, additions, older rooms without vents, upstairs bedrooms, and home offices. Systems can be set up as single-zone for one space or multi-zone to control several rooms independently.

Our ductless mini split maintenance in North Park keeps the system clean and responsive. Filters collect dust, drain lines can clog, and coils pick up debris over time. During service, we clean those components, check refrigerant levels, inspect electrical connections, and confirm the system is responding properly to controls. Regular maintenance helps keep temperatures consistent and prevents the system from working harder than it needs to.

When a ductless system has been running for years, wear starts to show. You might notice uneven temperatures, more noise, or frequent adjustments just to stay comfortable. At that point, a ductless mini split replacement in North Park can make a big difference. Modern systems are more efficient, quieter, and better suited for today’s living spaces.

Heat Pump Water Heater Services

Heat Pump Water Heater Services

Heat pump water heaters warm water by using heat already in the air around them instead of creating heat on their own. Because they use less energy to do the job, they can help lower monthly utility costs and reduce strain on the system. Our heat pump water heater services in North Park help you make the most of that efficiency and feel confident about upgrading.

A heat pump water heater installation in North Park can noticeably reduce how much energy your home uses for hot water, which is often one of the biggest monthly expenses. We install high-efficiency systems like the ProTerra Hybrid Electric heat pump water heater and handle the full process, from removing the old unit to setting up the new one. If you’re ready to upgrade, we’ll explain your options clearly and take care of everything.

Heating System Services

Heating System Services

North Park nights and mornings can be in the 40s and 50s during the winter months, and older homes can lose heat faster than people expect.

Our North Park heating services take care of everything behind the scenes so you don’t have to think about it. When your heat works the way it should, you get to focus on enjoying a warm, comfortable home instead of worrying about what’s going on with your system.

A new heating installation in North Park often means working around older construction, partial ductwork, or additions added decades later. Some homes were built before central heating was common, while others have been remodeled piece by piece over time. We look closely at how your home is laid out today, where heat is needed most, and how air can move through the space. From there, we install a system that heats evenly.

Heating maintenance in North Park is best done in the fall, before you really start relying on the system. Older systems especially benefit from a yearly check to make sure burners, electrical components, and safety controls are working properly. Regular maintenance helps prevent no-heat calls during cold spells and keeps systems running more reliably through the winter. Our maintenance plan helps keep this from slipping through the cracks year after year.

If your heat isn’t working, the last thing you should be doing is running space heaters or bundling up inside your own home. Heating problems often start once the system is running night after night—things like burners not lighting, weak airflow, strange smells, or the system shutting off when it shouldn’t. When you call us for your North Park heating repair, we show up quickly, figure out what’s going on, and fix the issue.

Replacing a heating system usually brings immediate relief. Rooms warm up faster, temperatures feel even, and you’re no longer wondering if the system will make it through the night. Your North Park heating replacement is also a chance to fix long-standing comfort issues caused by older layouts or outdated equipment. 

HVAC System Services

HVAC System Services

Guthrie & Sons is a full-service heating and air conditioning company that works on all major HVAC brands. Our HVAC services in North Park cover everything from brand-new systems to equipment that’s been running for years and just needs the right care.

From classic single-family homes to apartments, condos, and townhomes, we help keep North Park homes comfortable year-round with heating and cooling services that fit how you live.

Installing a new HVAC system is a good time to think about how you want your home to heat and cool—not just now, but long term. During your North Park HVAC installation, we can install a traditional setup like a furnace and air conditioner, or help you decide if a heat pump or ductless mini splits make more sense for your space. Some North Park homes do best with one system, while others benefit from a combination, like adding a mini split to an addition or an upstairs room.

Most homes benefit from having heating and cooling maintenance done once or twice a year. Systems that receive regular maintenance tend to last 3 to 5 years longer than systems that don’t. Routine maintenance can also improve efficiency by 10–15% and reduce the likelihood of unexpected breakdowns by nearly 40%. Keeping up with your North Park HVAC maintenance helps your system run the way it was designed to and lowers the chances of problems showing up.

When your heating or cooling system isn’t working, waiting it out can make things worse. Small problems won’t stay small for long. We offer emergency HVAC repair in North Park so you’re not stuck dealing with an uncomfortable home. Getting repairs done sooner usually means less damage, less downtime, and a faster return to normal.

An HVAC replacement in North Park doesn’t always mean installing the same system again. Some people stick with a furnace and AC, while others choose to upgrade to a heat pump for better efficiency. In some cases, adding a ductless mini split to a specific area—like an addition or upstairs room—makes the most sense. We help you compare options and handle the full replacement so your new system fits your home and your comfort needs.

As a Daikin Pro Elite Contractor, we offer HVAC system monitoring in North Park to keep track of how your system is performing. This technology monitors operation and alerts us if something isn’t working as it should. When service is needed, we already have the system data, which helps make service visits quicker and more accurate.

Frequently Asked Questions

The $5,000 rule is a quick way to think through a repair-versus-replace decision. You take the age of your system and multiply it by the estimated repair cost. If that number is under $5,000, repairing often makes sense. If it’s over $5,000, replacement may be the better long-term move. It’s not a hard rule—just a helpful starting point when weighing your options.

Most heating service calls start around $100, depending on the system and what’s going on. That covers a technician coming out, checking the system, and figuring out why it’s not working right. 

When your heat isn’t working, you want a licensed heating contractor. Heating systems involve gas, electricity, and safety controls, and those aren’t things to experiment with during DIY heating repairs. A trained technician knows what to look for, how to fix it safely, and how to make sure everything is running the way it should afterward.

If your heater is newer and the issue is fairly simple, repairing it usually makes sense. If it’s older, needs repairs often, or just isn’t keeping your home comfortable anymore, replacement can be the better move. We’ll look at the full picture and help you decide without pressure.

Guthrie & Sons has always been super professional and knowledgeable about our system. They did the install a few years ago and have continued to maintain it for us. This year we noticed that our system wasn't performing as well, so when Wayne came out, he noticed a likely leak and was back 2 days later to find and fix it. He was quick, professional, and just extremely nice! 100% recommend.

Called one of the "big guys" in town and the estimate to do what needed to be done to diagnose my problem was nearly 1/2 the cost of the system when I purchased it and had it installed 5.5 years ago, I found Guthrie & Sons and they came out the same day and did the same work for 1/4 the price I was quoted for the same exact work! Daniel was friendly, honest and quickly got my system working as expected. I even purchased the service plan so I don't have future problems. I highly recommend these guys, they were awesome, don't get ripped off call Guthrie & Sons!!!

Matt and Bryan are truly the A-Team! Their teamwork was outstanding and the workmanship was meticulous. The air handler was carefully installed, wiring neatly secured, plenum perfectly fitted, and the condenser precisely positioned and leveled for proper clearance and vibration control. The line set was pressure-tested and vacuumed as well. They also left the work area clean and neat.

Please congratulate them for a job well done!

After dealing with several HVAC companies, Guthrie & Sons clearly stood out as the most ethical, honest, and reliable. From the very beginning, their approach felt transparent and genuinely focused on what was best for us—not on upselling or unnecessary replacements.

We worked with Vlad T., who had previously been out to our home and saved us tens of thousands of dollars by getting our existing AC unit up and running when other companies were pushing for a full replacement. That experience alone earned our trust.

Now that we’re finally ready to purchase new units, there was no question that Guthrie & Sons was the only company we would consider, and Vlad was the obvious choice. He was extremely professional, punctual, and exceptionally knowledgeable, taking the time to explain options clearly and thoroughly. His expertise and honesty made the entire process straightforward and stress-free.

If you’re looking for an HVAC company you can truly trust—one that values integrity, quality workmanship, and customer service—I cannot recommend Guthrie & Sons and Vlad T. highly enough. This is how service should be done.

The layout of my condo made installing splits challenging, and before I met with Guthrie and Sons, three companies either told me that it couldn't be done. Vlad studied my apartment until he found a way to install with minimal openings in the walls and without a second condenser. Mallory, who works in the office, always followed through and advised me when I ran into a hiccup and needed detailed plans for the city. My HOA appreciated Guthrie and Sons' thoroughness and was so impressed with the design, that another resident who had been wanting splits for years, decided to install splits at the same time. The team that came in was knowledgeable, professional, and hard working. They finished a day ahead of time. I'm thrilled with the way everything looks and works.

I’ve been using Guthrie & Sons for over 15 years. They installed my whole AC system and maintained it all those years and never had an issue. Well it was time for an upgrade and they’ve recently installed my second system. The team 15 years ago and the team this time around were both amazing, professional and clean. I can’t recommend them enough Matt, Ben, Christian and Bryan get 10 stars. They are a bit pricier but worth the investment when you have peace of mind and almost two decades of great service and no issues.

I have a maintenance plan for my heat pump and air conditioner which Guthrie & Sons installed two years ago. I am very happy with my system as well as the maintenance plan. Wayne, one of their excellent technicians, just completed the Fall service and now the system is ready for winter use. He is knowledgeable and has been able to answer any questions I have about my system. In addition, the office at Guthrie & Sons is very responsive and follows through on any questions and concerns within 24 hours if not immediately. Great service from a great company.

We recently had our A/C replaced by Guthrie & Sons, and I cannot recommend them highly enough. After getting five different bids, Guthrie & Sons stood out immediately—not just on price, but on expertise and professionalism. They even brought their engineers out to ensure the work could be done the right way, which gave us tremendous peace of mind.

From start to finish, their team was outstanding. They worked incredibly hard, treated our home with respect, and left everything spotless—truly the cleanest job site I’ve ever seen after a major project. The installation itself was seamless, and the quality of their work shows in every detail.

If you’re looking for a company that combines deep knowledge, excellent craftsmanship, and genuine care for their customers, Guthrie & Sons is it. Absolutely five stars across the board!

We had a wonderful experience with Guthrie and Sons. Anthony was our estimator and he did a very thorough job of explaining all of our options! Matthew, Bryan, and Isaiah were our installers and they were very efficient, capable, and personable. Our home did not have an existing HVAC system so they had to build the whole thing in an older house that had undergone several additions. We were up and running in just three days. They left the worksite clean at the end of each day. We highly recommend Guthrie and Sons!

Kareen did an outstanding job with our HVAC system. From start to finish, he demonstrated professionalism, patience, and a strong commitment to getting the job done right. Even when faced with several unexpected challenges, he handled each one with skill and determination, never compromising on the quality of his work.

What really stood out was his problem-solving ability and willingness to go the extra mile to ensure everything was operating as it should. He communicated clearly throughout the process, kept us updated, and made sure we felt confident in the work being done.

It’s not often you come across someone who combines technical expertise with such a strong work ethic and positive attitude. We’re very grateful for his efforts and would highly recommend Kareen to anyone needing reliable HVAC service.
