Davco Heating & Cooling has been serving Shelby Township and the surrounding Macomb County area since 2011. That is roughly 15 years of showing up on time, diagnosing problems accurately, and getting heating and cooling systems running again for homeowners and businesses across the region. We handle the full range of HVAC work, from same-day emergency repairs to complete system installations, and we do it with the kind of straightforward approach you would expect from a locally rooted company that has built its reputation one job at a time. Call us and we'll walk you through your options.
For residential and commercial HVAC work alike, we cover everything a home or business needs to stay comfortable through every season. That means AC repair and service, furnace repair and installation, heat pump service, full HVAC system replacement, thermostat and smart-control installation, ductwork repair and sealing, indoor air quality and air filtration, and seasonal maintenance and tune-ups. Whether you are dealing with a system that stopped working overnight or planning a full replacement before the next heating season, we have the experience to handle it.
Our technicians diagnose the actual problem first, whether that is a refrigerant leak, an airflow issue causing uneven temperatures, a failing compressor, or a blower motor that is struggling to keep up. We also install and service mini-split and ductless systems for homes and commercial spaces that need flexible, targeted comfort without running new ductwork. With transparent pricing with no hidden fees on any HVAC job, you will know what the work involves and what it costs before anything gets started. We'll get the job done and the system running.
Before a small issue turns into a full breakdown, it pays to have your furnace looked at by someone who knows what they are doing. Macomb County winters are cold, sustained, and unforgiving. A furnace that struggles in October has a way of becoming a no-heat emergency in January, and that is not a situation anyone wants to be in when temperatures drop below freezing.
We handle everything on the furnace side: furnace not heating, furnace tune-up and maintenance, furnace inspection, new furnace installation, and furnace replacement when a system has reached the end of its useful life. Same-day furnace repair is available when the situation calls for it. Our qualified HVAC technicians diagnose the problem before recommending repair or replacement, so you get an honest answer rather than an automatic upsell. The work is code-compliant HVAC work on every job, done right the first time and built to last through the seasons ahead.
Furnace fixed. AC humming. Home comfortable again.
Give us a ring and we'll take care of it.
If you're not sure your system can keep up, Shelby Township summers give it a real test. The heat here comes with humidity, and when an air conditioner starts blowing warm air or stops cooling altogether, it stops being an inconvenience and starts being a genuine problem. We take AC calls seriously because we know what a failed system means on a hot August afternoon.
We repair and service all types of central air systems: AC not working, AC blowing warm air, uneven cooling throughout the house, and units that run constantly without reaching the set temperature. Our technicians clean evaporator coils, service condensers and compressors, and check refrigerant levels as part of a thorough diagnostic process. We also handle full air conditioner replacement and new central air installation when a system is too far gone to repair economically. On older units, energy efficiency is often reason enough to consider replacement, and we will give you a straight answer on whether repair or replacement makes more sense for your situation. Emergency and same-day AC repair are available when you need help fast.
For homeowners and property managers who want it done right, heat pumps and ductless systems offer a practical and efficient option for a lot of situations in Macomb County. They perform well during the shoulder seasons, handle additions and sunrooms that lack existing ductwork, and give you independent temperature control in spaces that need it.
We install, repair, and service heat pumps and mini-split systems throughout the area. That covers heat pump repair, heat pump not working, heat pump replacement, new heat pump installation, heat pump tune-up, emergency heat pump repair, mini-split installation, mini-split repair, and ductless AC installation. If you are considering a heat pump for a new installation or replacing an aging system, we can walk you through what makes sense for your home or property.
The work we do is only as good as the people doing it. Every job is handled by trained HVAC technicians who have worked through the full range of residential and commercial heating and cooling situations this area throws at them. That means familiarity with the equipment, the local building requirements, and the kind of problems that show up in Michigan homes after years of hard winters and humid summers.
We take the job seriously from the moment we arrive. We protect your floors and finishes while we work, we clean up after ourselves, and we do not leave until the system is running and you understand what was done. There are no rushed walkthroughs or vague explanations. If something needs to be said about the condition of the system or what to watch for down the road, we say it plainly.
A well-functioning HVAC system depends on more than just the furnace or air conditioner at its center. Leaking ductwork wastes heat in winter and cool air in summer, driving up energy costs while making it harder to keep the house at a consistent temperature. We handle duct sealing, air duct repair, and ductwork replacement for homes and commercial spaces where the distribution side of the system is letting the rest of it down.
The thermostat is the control center of the whole system, and a faulty or outdated one can cause all kinds of comfort and efficiency problems. We install thermostats and smart thermostat systems, including programmable and Wi-Fi-connected controls that give you better management of your home's temperature without unnecessary energy use.
Indoor air quality matters especially during Michigan's cold months, when homes are sealed tight and the same air circulates for weeks at a time. We install whole-home air filtration systems, air purifiers, air scrubbers, and whole-house humidifiers that make a real difference in how the air inside your home feels and performs. Hire us and you're hiring a neighbor who knows your home.
For residential and commercial HVAC work alike, we bring the same reliability and straightforward approach to office buildings, retail spaces, and light commercial properties throughout Shelby Township and Macomb County. Commercial clients need minimal downtime and a technician who shows up when scheduled and gets the system back online without unnecessary delays.
We handle commercial HVAC repair, commercial AC repair, commercial heating repair, commercial HVAC maintenance, commercial HVAC installation and replacement, and rooftop unit repair and service. Qualified technicians on the job means the work gets done correctly and to code, whether it is a routine maintenance visit or an emergency repair during business hours.
Booking an HVAC service call is simple, and when the situation is urgent, we make it even easier. A no-heat call in January or a no-cool call in August is not a wait-until-Monday situation in this part of Michigan. We are available around the clock for emergency HVAC service because the climate here does not take weekends off.
We pick up the phone, we give you a straight answer on timing, and we show up. Emergency furnace repair, emergency AC repair, emergency heat pump repair, and same-day HVAC service are all available when you need help fast. We keep our schedules organized so that urgent calls get the response they deserve, and we will always let you know what to expect before we arrive.
Not the biggest outfit in town. Just the most reliable. Always on time.
One of the most common frustrations people have with HVAC service is not knowing what something will cost until after the work is done. We do not operate that way. Before any work begins, we explain what the job involves, what it will cost, and whether there are options worth considering. That applies to everything from a diagnostic service call to a full system replacement.
Whether you are asking about furnace repair cost, AC repair cost, heat pump installation cost, or the cost of replacing an aging central air system, we give you a real answer based on your actual situation. Call for a quote or to schedule a service call, and we will walk you through the pricing before a single tool comes out of the bag.
We are based in Shelby Township and serve the broader Macomb County region. That includes Sterling Heights, Utica, Romeo, Washington Township, Chesterfield Township, Clinton Township, Troy, and Macomb Township, along with the communities in between.
This area demands a reliable HVAC system year-round. Cold winters, humid summers, and the shoulder seasons in between put real stress on heating and cooling equipment. We know the local climate, the local housing stock, and the kinds of problems that come up repeatedly in homes and businesses across the county.
We have been serving Shelby Township and the surrounding Macomb County communities since 2011, which puts us at roughly 15 years in business. Over that time we have built our reputation one job at a time, working with homeowners, landlords, and commercial clients across the region.
Our home base is Shelby Township, and we regularly serve Sterling Heights, Utica, Romeo, Washington Township, Chesterfield Township, Clinton Township, Troy, Macomb Township, and the communities in between. If you are in Macomb County or the surrounding metro area and are not sure whether we reach you, call (586) 789-9445 and we will confirm.
Our technicians are trained HVAC professionals who have worked through the full range of heating and cooling situations this region produces, from no-heat emergencies in deep Michigan winters to AC failures during summer heat. They diagnose accurately, explain clearly, and do not leave until the system is running and you understand what was done.
We stand behind the work we do. If something is not right after a repair or installation, call us and we will make it right. We take every job seriously regardless of size, and our reputation in this community over 15 years reflects that commitment.
We keep our schedules organized and communicate arrival windows clearly when you book. If something changes on our end, we let you know before the appointment window closes. Showing up when we say we will is a basic part of how we operate, not an exception.
It means the people answering the phone and showing up at the door are part of the same community you live in. We are accountable to our neighbors in a way that matters to us personally. When you call, you reach someone who knows Macomb County and the kinds of homes and systems common here.
We coordinate that when you call and schedule accordingly. For properties with multiple systems or for commercial clients who need several units serviced in one visit, we plan the appointment to give the job the time it requires. We do not rush through a multi-system visit to fit an unrealistic window.

How do I know whether to repair or replace my furnace or AC?
The main factors are system age, repair cost, and efficiency. A furnace or AC that is 15 or more years old and facing a repair that costs more than a third to half of what a new system would run is usually a better candidate for replacement. We give you an honest assessment of both options, including what the repair involves and what a comparable new system would cost, so you can make the call with clear information.
What are the signs that my heating or cooling system needs attention soon?
Weak or uneven airflow, a system that cycles on and off more frequently than it used to, warm air coming from the vents when the AC is running, unusual sounds like banging or grinding, or a furnace that struggles to hold temperature on a cold day are all worth a call. Catching a problem early almost always means a simpler repair than waiting until the system stops working entirely.
Why is one room in my house always hotter or colder than the rest?
Uneven temperatures usually point to a ductwork issue, an airflow imbalance, or a zoning problem. Leaking duct sections, a damper that is not operating correctly, or a thermostat that is not reading the space accurately can all cause one area to fall out of range. We inspect the full system to trace the source rather than guessing at the fix.
Transparent Upfront Pricing
We explain the full scope and cost before any work begins. There are no hidden fees on any HVAC job, and nothing shows up on the invoice that was not discussed and approved first.
How often should I schedule maintenance on my HVAC system?
Twice a year is the standard recommendation: a spring tune-up before cooling season and a fall tune-up before heating season. Each visit covers inspection, cleaning, and a check of the components most likely to cause a breakdown. Regular maintenance extends system life and keeps efficiency up, which shows up in your energy bills over time.
What does a seasonal tune-up actually cover?
On a maintenance visit, we inspect and clean the key components, test system operation, verify refrigerant levels, check airflow through the system, and flag anything that looks like it could become a problem before the heavy-use months arrive. The goal is to catch a worn part or a dirty burner in October rather than deal with a breakdown in February.
Is a cold-climate heat pump a realistic option for a Michigan home?
Yes, and it has become a much more practical choice in recent years. Modern cold-climate heat pumps are rated to operate efficiently down to roughly -15 degrees Fahrenheit, which covers even the coldest stretches in Macomb County. A heat pump handles both heating and cooling in a single system, and energy efficiency incentives have made them a fast-growing option for homeowners replacing aging equipment. We can walk you through whether it makes sense for your home and your existing setup.
Same-Day and Emergency Availability
Heating and cooling failures do not wait for business hours. We offer same-day and urgent response for no-heat and no-cool situations across Shelby Township and the surrounding area.
What causes a system to short-cycle, meaning turn on and off too frequently?
Short-cycling has several common causes: an oversized system that heats or cools the space too quickly, a dirty filter restricting airflow, a refrigerant issue, or a failing component like a pressure switch or control board. It puts extra wear on the system and drives up energy use. A diagnostic call usually identifies the cause quickly.
How does leaking ductwork affect my energy bills?
Leaking ducts can send a meaningful share of the conditioned air your system produces into attics, crawl spaces, or wall cavities before it ever reaches a living area. The result is a system that runs longer to hit the set temperature, which raises energy costs and puts more wear on the equipment. Sealing or repairing the ductwork gets that conditioned air back where it belongs.
Code-Compliant Work on Every Job
Every installation and repair we perform meets current code requirements. Work is carried out by qualified HVAC technicians who treat every job, large or small, with the same standard of care.
Do I need to be home when the technician comes out?
Someone should be present who can grant access to the equipment and answer a few questions about what the system has been doing. You do not need to stay in the room during the work, but having someone available to review the findings and approve any repair before we begin is part of how we keep the process straightforward and transparent.
How does pricing work, and will the quote change once work starts?
We give you a clear price before any work begins and we stand behind it. If additional issues are discovered once the system is open, we communicate that before proceeding. You will not find a charge on the invoice that was not discussed and approved beforehand. Transparent pricing with no hidden fees on any HVAC job is something we take seriously on every call.
What should I do if my heat stops working in the middle of the night?
Check the thermostat first to confirm it is set to heat and the temperature is set above the current room temperature. If the display is blank, check whether the circuit feeding the furnace has tripped. If none of that restores operation, call us. We offer same-day and urgent service for heating emergencies, and when you call you reach someone who can get a technician dispatched as quickly as possible.
Every home and every system is a little different, so call us at (586) 789-9445 and we will talk through what you are dealing with and get the right service scheduled.
