Dierkes Heating & Air has been the locally owned heating and cooling contractor Coon Rapids and Anoka County have counted on since 2013. Over more than a decade, we have worked on homes, rental properties, and commercial buildings across the area, handling everything from a furnace that quit on a January morning to a full system replacement in the middle of July. We are personally accountable for every job we take on, and when you call, you reach someone who knows this area and cares about the work. Call us today at (612) 665-9289 to request a quote or schedule a service call.
For residential and commercial HVAC work alike, we handle the full range of heating and cooling needs that come up in this part of Minnesota. Whether you need a quick repair or a complete system overhaul, our team is equipped to get the job done right. Here is what we do:
We work with homeowners, landlords, property managers, and business owners throughout Coon Rapids and the surrounding communities. The goal is always the same: comfortable air, reliable equipment, and no surprises on the bill.
Don't let a small problem turn into a no-cool afternoon when the temperature climbs into the nineties. If your air conditioner has stopped working, is blowing warm air, or is struggling to keep up with the heat, our technicians will diagnose the issue and explain exactly what is going on before any work begins. Common calls include refrigerant leaks, compressor problems, condenser coil issues, and evaporator coil buildup. We also handle airflow problems and uneven temperatures throughout the home, which often trace back to the air handler, the coil, or the ductwork rather than the unit itself.
When a repair no longer makes sense, we handle full central air installation and replacement as well. We will walk you through your options, size the system correctly for your home, and complete the installation with qualified HVAC technicians on the job. We protect your floors and finishes while we work, and we leave the space clean when we are done.
Anoka County winters are not forgiving, and a furnace that fails in February is not a problem you want to troubleshoot on your own. We repair gas furnaces of all makes and models, including systems that will not turn on, furnaces blowing cold air, burners that will not ignite, and heat exchangers showing signs of wear. Our technicians will get to the root of the problem and give you straight answers about your furnace, AC, and ductwork, no surprises.
Annual fall tune-ups are one of the most practical things a homeowner in this climate can do. A well-maintained furnace runs more efficiently, lasts longer, and is far less likely to leave you without heat when temperatures drop below zero. When a furnace has reached the end of its useful life, we handle full replacement and installation, helping you choose a system that fits your home and your budget. Pick up the phone and we'll handle the system.
Heat pumps have become a strong option for Minnesota homeowners, especially the cold-climate models designed to perform efficiently even when temperatures fall well below freezing. We install, service, and repair heat pump systems throughout the Coon Rapids area, including diagnosing systems that are not heating or cooling properly, refrigerant issues, and defrost cycle problems. If you are considering a heat pump for the first time, we can walk you through what to expect in a Minnesota winter and whether the technology is a good fit for your home.
Mini-split and ductless systems are an excellent solution for home additions, older homes without existing ductwork, or any space that the central system does not reach well. We handle ductless installation and repair for both single-zone and multi-zone setups. Reach out and we'll start at the unit.
Leaking or damaged ductwork is one of the most common reasons a home feels uncomfortable even when the HVAC equipment is running fine. If certain rooms are too warm or too cold, or if your energy bills seem higher than they should be, the duct system is often the place to start. We repair, seal, and replace ductwork throughout the home, improving airflow and helping the system run the way it was designed to.
A thermostat that is not reading temperatures accurately, failing to hold a schedule, or simply past its useful life can make the whole system feel unreliable. We install programmable thermostats and smart controls, including Nest and Ecobee models, and we make sure the new control is wired and configured correctly before we leave. It is a straightforward upgrade that often makes a noticeable difference in day-to-day comfort.
Minnesota winters mean months of closed windows and recirculated indoor air. Whole-home air purifiers and upgraded filtration systems help remove dust, allergens, and other particles that build up over a heating season. We also install whole-home humidifiers, which are particularly valuable in this climate. Dry winter air is hard on wood floors, furniture, and the people living in the home, and a properly sized humidifier makes a real difference in how comfortable the space feels.
Whether it's a one-time repair or a full system replacement, we understand that some calls cannot wait. A furnace that goes out overnight, an air conditioner that stops working on the hottest day of the year, a system that is short-cycling or making sounds it never made before: these are situations where you need someone available and ready to respond. We offer same-day service options and after-hours availability for HVAC emergencies throughout Coon Rapids and the surrounding area.
When you call with an emergency, we will get a technician to you as quickly as possible. We diagnose the problem, explain what we found, and give you a clear picture of what it will take to fix it before work begins. No pressure and no gimmicks, just reliable comfort.
Call in the morning. Comfortable by afternoon. Follow-up when you need it.
Property managers trust us to keep their buildings comfortable through every season. We work with office buildings, retail spaces, multi-unit properties, and other commercial facilities throughout Anoka County, handling repairs, system replacements, and scheduled maintenance. Commercial HVAC equipment runs harder and longer than residential systems, and keeping it well-maintained protects the investment and keeps tenants and customers comfortable.
We are familiar with the demands of managing a commercial property and the need for fast, reliable service with minimal disruption to the business. We make the repair and leave the home tidy.
Booking an HVAC service call is simple, and a seasonal tune-up is one of the best ways to stay ahead of problems before they become expensive repairs. A spring AC tune-up covers the condenser, the coil, refrigerant levels, electrical connections, and airflow through the system. A fall furnace tune-up covers the heat exchanger, burners, ignition system, filter, and overall safety of the unit. Both visits are straightforward and typically completed in a single appointment.
In a climate with hard winters and warm summers, the equipment runs at full capacity for months at a time. Regular maintenance extends the life of the system, keeps it running efficiently, and gives you confidence heading into the season. If the technician spots something that could become a problem, you will hear about it clearly and honestly, with no pressure to make a decision on the spot.
When you call us for an estimate, you will get a clear explanation of what the work involves and what it will cost. We treat your home the way we'd want ours treated, and that means no hidden fees, no vague answers, and no pressure to approve work before you are ready. We are happy to walk through the options with you, explain what we recommend and why, and let you make the decision that makes sense for your situation.
Honest quotes. Code-compliant work. Reliable comfort.
Scheduling is straightforward from start to finish.
That is the whole process. No surprises, no runaround, just the work done right.
We are not satisfied until the system is running the way it should and you feel good about the service you received. If something is not right after we leave, call us. We will come back and make it right. That is not a policy statement; it is simply how we operate. Every job we take on reflects on us personally, and we take that seriously.
We are based in Coon Rapids and serve customers throughout Anoka County and the northwest metro. Our regular service area includes Blaine, Andover, Anoka, Champlin, Ham Lake, and Brooklyn Park, along with the communities in between. If you are nearby and need HVAC service, give us a call. We know the area well and can typically get to you quickly.
We have been doing this work since 2013, which puts us past the ten-year mark in this area. Over that time we have worked on homes, rental properties, and commercial buildings throughout Coon Rapids and the surrounding communities. The business has grown the way a local company grows: one job at a time, one neighbor at a time.
Yes. If something is not right after we leave, call us and we will come back and make it right. We are personally accountable for every job we take on, and that accountability does not end when we pull out of the driveway. Every job we do reflects on us directly, and we take that seriously.
We are available every day from 9:00 AM to 10:00 PM, including weekends. Heating and cooling emergencies do not follow a business-hours schedule, and we make ourselves reachable during that extended window for urgent no-heat and no-cool situations throughout the Coon Rapids area.
When you call, you reach someone who is part of the same local community you are in, not a distant office. When a technician arrives, it is someone who takes the work seriously and knows that a good reputation in Anoka County is built job by job. We are a locally owned operation, and the people you talk to are the people responsible for the outcome.
We work with homeowners, landlords, property managers, and small commercial clients throughout Coon Rapids and the surrounding area. Residential work is our core, but we understand what a property manager needs: clear communication, reliable scheduling, and work that does not require a follow-up call. Whatever the customer type, the standard of care is the same.
We start every visit with a thorough inspection and diagnosis before recommending anything. We explain what we found, what caused it, and what the repair involves, and we get your approval before starting work. We do not recommend services you do not need, and we will tell you plainly if a repair is straightforward or if there is something more significant going on.
Dierkes Heating & Air is ready to help with any heating or cooling need, from a simple repair to a full system installation. We serve homeowners, property managers, and commercial clients throughout Coon Rapids and the surrounding communities. Call (612) 665-9289 today to request a quote or schedule your service call.

How do I know whether to repair my furnace or replace it?
The decision comes down to the age of the equipment, the cost of the repair, and how efficiently the system has been running. A furnace that is more than 15 to 18 years old and needs a significant repair is often a better candidate for replacement than continued service. We give you straight answers about what the repair involves and what a replacement would cost, with no pressure either way. If repair makes sense, we say so. If the numbers point toward replacement, we walk through the options clearly so you can decide what fits your home and budget.
What causes a system to stop heating or cooling entirely?
The most common causes are a failed ignition component, a tripped limit switch, a refrigerant issue, a blower motor problem, or a thermostat that has lost communication with the equipment. A clogged filter can also shut a system down by restricting airflow past the point the equipment can handle. When we arrive, we start with a full inspection of the unit and its controls to find the root cause before recommending anything.
How often should I schedule a maintenance tune-up?
Once a year for each season the equipment runs is the standard recommendation: a furnace tune-up in the fall before heating season, and an AC tune-up in the spring before the first hot stretch. If you run a heat pump year-round, an annual inspection covers both functions. Regular tune-ups are the most straightforward way to catch wear early and avoid the repair calls that tend to happen at the worst possible time.
Same-Day and Emergency Availability
We make same-day appointments available for urgent situations and respond to no-heat and no-cool calls every day from 9 AM to 10 PM. A Minnesota winter does not wait, and neither do we.
What does a seasonal tune-up actually cover?
A tune-up visit covers cleaning, a full system inspection, a controls check, airflow measurement, and a look at anything showing early signs of wear. We also use tune-up visits to troubleshoot uneven temperatures and airflow problems that homeowners have been living with but never had addressed. The visit ends with a clear explanation of what we found and what, if anything, needs attention.
Can I stay home while the work is being done, or do I need to be there?
You do not need to be present for routine service or a tune-up, but we do ask that an adult be available at the start of the visit so we can confirm access to the equipment and go over what we find. For larger jobs like system installation or replacement, it is helpful to have someone on-site for the duration. We will let you know what makes sense when you call to schedule.
Why is one room in my home hotter or colder than the rest?
Uneven temperatures usually point to a ductwork problem, a zoning issue, or equipment that was not sized correctly for the home. Leaking or poorly sealed ducts lose conditioned air before it reaches certain rooms, and a duct inspection can identify where the losses are happening. A thermostat or controls issue can also cause uneven distribution. We inspect the full system, not just the unit, to find what is driving the imbalance.
Transparent Upfront Pricing
Every job starts with a clear quote covering parts and labor before any work begins. We explain what is driving the cost so there are no surprises when the work is done.
What do strange noises from my HVAC unit usually mean?
Banging or clanking often points to a loose or failing mechanical component. A high-pitched squeal can indicate a blower motor or belt issue. Clicking at startup or shutdown is sometimes normal, but clicking that continues through operation can signal a controls or ignition problem. Rattling may mean debris in the system or a loose panel. If a noise has started recently or is getting louder, it is worth having a technician take a look before the problem develops further.
Is a cold-climate heat pump actually practical in Minnesota?
Modern cold-climate heat pumps are rated to operate efficiently down to roughly -15 degrees Fahrenheit, which covers the range of temperatures Coon Rapids sees in a typical winter. They work well as a primary heating source in well-insulated homes and as a supplement to an existing system in others. We can walk through whether the equipment makes sense for your specific home, your existing ductwork or lack of it, and your heating setup before you commit to anything.
Clean and Respectful Workmanship
We protect your floors and finishes while we work and leave the space the way we found it. Work performed by qualified HVAC technicians means the job is done right and the home is left tidy.
How does a whole-home humidifier differ from a portable unit?
A whole-home humidifier integrates directly with your existing air handler and delivers controlled humidity to every room through the duct system. A portable unit treats only the space it sits in and requires regular refilling. The whole-home system is calibrated to work with your thermostat or smart control, and once it is set up, it operates automatically without the maintenance that portable units require. Most homeowners notice the difference in comfort within the first few days of heating season.
How do I know if my system has a refrigerant or airflow problem?
Signs of a refrigerant issue include an AC that runs continuously but cannot cool the space, ice forming on the outdoor unit or refrigerant lines, or a noticeable drop in cooling output without an obvious cause. Airflow problems tend to show up as weak output from vents, rooms that take much longer than expected to reach the set temperature, or a system that short-cycles. Both issues get worse the longer they sit, so calling sooner rather than later limits the damage.
How do estimates and pricing work before any work begins?
We provide a clear quote that covers what the job involves, what the parts cost, and what the labor looks like before any work begins. If the technician finds something additional that needs attention, we explain it and get your approval before proceeding. There are no charges added after the fact for work that was not agreed on. The goal is that you understand exactly what you are paying for before we start.
Every home and building is a little different, and the right answer for your system depends on the specifics. Call us at (612) 665-9289 and we will talk through what you are seeing, get you on the schedule, and make sure you have straight answers before any work begins.
