When your heat goes out in January or your AC quits in July, you need a contractor who picks up the phone and shows up on time. Davco Heating & Cooling has been doing exactly that for Shelby Township homeowners and Macomb County businesses since 2011. We handle everything from a furnace that won't fire to a full system replacement, and we do it with transparent pricing with no hidden fees on any HVAC job. Furnace fixed. AC humming. Home comfortable again.
Whether you own a single-family home, manage a rental property, or run a commercial building, we are ready to help. Same-day availability means you are not waiting a week to get a technician out. Call (586) 789-9445 for a quote or to schedule service.
For residential and commercial HVAC work alike, we cover the full range of heating and cooling needs that come up across every season. One call gets you access to a team that handles it all.
Our services include:
We work with homeowners, landlords, property managers, and business owners across the area. Give us a ring and we'll take care of it.
If you're not sure your system can keep up, do not wait until it stops working entirely. A struggling air conditioner usually shows signs before it fails completely, and catching the problem early saves time, money, and a miserable few days without cooling.
When we come out for an AC service call, we diagnose the full system. That means checking refrigerant levels and testing for leaks, inspecting the condenser and compressor, examining the evaporator coil, and tracing any airflow or uneven-temperature issues back to the source. If the fix is straightforward, we handle it that visit. If the system is older or the repair cost no longer makes sense, we will walk you through replacement options honestly.
For new installations and full system replacements, we handle central air installation from start to finish. Work is performed by qualified HVAC technicians, and we deliver code-compliant HVAC work on every job. Call us and we'll walk you through your options.
Before a small issue turns into a full breakdown, it pays to have a technician take a look. A furnace that cycles too often, blows lukewarm air, or makes unfamiliar sounds is telling you something. In a Michigan winter, ignoring it is not an option.
On a heating service call, our technicians check the heat exchanger, burners, igniter, blower motor, and airflow throughout the system. We diagnose the problem and give you a straight answer on whether a repair makes sense or whether replacement is the smarter move. If the furnace is aging out or the repair cost approaches the value of the unit, we will tell you that directly.
For furnace replacement and new installation, we handle the full job. Same-day availability means that if you wake up to no heat, we can often get a technician out the same day. Emergency furnace repair is available when you need it most. We'll get the job done and the system running.
Michigan winters are long, sub-freezing, and hard on heating systems. The area also deals with the dry indoor air that comes with months of forced-air heat running around the clock. The three services below come up constantly in this part of the state, and we have built real experience around each one.
Shelby Township winters push heating systems to their limits. When a furnace fails in February, it is not an inconvenience, it is an emergency. On a repair call, our technicians trace the problem to the source, whether that is a faulty igniter, a failing heat exchanger, a blower issue, or a control board problem. We explain what we find and what it will cost before any work begins.
When a system is beyond repair or simply too old to run efficiently, replacement is the right call. We handle new furnace installation from equipment selection through final startup, with work performed by qualified HVAC technicians every step of the way.
Modern cold-climate heat pumps are rated to operate efficiently down to roughly -15 degrees Fahrenheit, which makes them a genuinely viable option in Michigan now. A heat pump handles both heating and cooling in a single system, which means one piece of equipment covers your home year-round.
We install central heat pump systems as well as mini-split and ductless setups for homes without existing ductwork or for room-by-room comfort control. If you are replacing an aging furnace or central AC and want to explore a heat pump as the upgrade, we will walk you through what makes sense for your home and your budget. Energy efficiency incentives have made cold-climate heat pumps a fast-growing option across Macomb County, and we can help you understand what is available.
Forced-air heating pulls moisture out of the air, and Michigan winters are already dry. The result is cracked wood trim, static electricity, dry skin, and air that simply feels uncomfortable even at the right temperature. A whole-home humidifier integrates directly with your HVAC system and maintains consistent humidity levels throughout the house automatically.
Installation involves connecting the humidifier to the furnace or air handler and tying it into the existing ductwork and water supply. It is a straightforward upgrade that makes a noticeable difference in comfort and indoor air quality from the first week of operation.
For homeowners and property managers who want it done right, the supporting systems matter just as much as the main equipment. A smart thermostat that is not wired correctly or ductwork that leaks conditioned air into the attic will undercut even the best furnace or AC unit.
We install programmable and smart thermostats, including whole-home zoning and comfort-control setups. If your thermostat is not responding correctly or you want to upgrade to a system you can control remotely, we handle the full installation.
Leaking or poorly sealed ductwork is one of the most common sources of high energy bills and uneven temperatures. We inspect, repair, and seal ductwork to get conditioned air where it belongs. We also handle full ductwork replacement when the existing system is beyond patching.
For indoor air quality, we install whole-home air filtration systems, air purifiers, and air scrubbers that work with your existing HVAC equipment. We protect your floors and finishes while we work, and we leave the space clean when the job is done. Call us and we'll walk you through your options.
Booking an HVAC service call is simple, and a seasonal tune-up is one of the best calls you can make before the heavy-use months arrive. A spring AC tune-up gets your cooling system ready before the heat hits. A fall furnace tune-up catches problems before the first cold snap.
During a maintenance visit, we inspect and clean the key components, test system operation, check refrigerant levels, verify airflow, and flag anything that looks like it could become a problem. Catching a worn part or a dirty burner in October is far less disruptive than dealing with a breakdown in January.
Regular maintenance extends system life, keeps efficiency up, and gives you confidence heading into each season. Call (586) 789-9445 to schedule a tune-up and get ahead of the next season. We'll get the job done and the system running.
A heating or cooling system that goes down does not wait for business hours. When you have no heat on a cold Michigan night or no AC during a summer stretch, you need a technician available now, not in three days.
We offer same-day and urgent service for heating and cooling emergencies. When you call, you reach someone who can get a qualified technician dispatched quickly. We will tell you what to expect on arrival and give you a straight answer on the repair before any work begins.
If your furnace stops working, your AC shuts down, or your system is showing signs of a serious problem, call (586) 789-9445 right away. Furnace fixed. AC humming. Home comfortable again.
Property managers, office building owners, and retail operators need HVAC work handled quickly and done right the first time. A system failure in a commercial space affects employees, customers, and operations, and it cannot sit unresolved for days.
We handle commercial AC repair, commercial heating repair, full commercial system installation and replacement, and scheduled commercial maintenance. Our technicians approach commercial work with the same thoroughness as residential, and we communicate clearly with property managers and building owners throughout the job.
For commercial buildings of all sizes in and around Macomb County, we are available for both urgent repairs and planned service. Give us a ring and we'll take care of it.
Booking an HVAC service call is simple when you know who you are calling. We have been serving Shelby Township and the surrounding communities since 2011, and this area is home. The same people who answer the phone are the ones who show up at the door.
Hire us and you're hiring a neighbor who knows your home. We take that seriously. We show up on time, we explain what we find, and we stand behind the work. Transparent pricing with no hidden fees on any HVAC job means you know what you are paying before we start. No surprises on the invoice.
We are proud of the reputation we have built over the past 15 years, and we work to earn it on every call.
We serve Shelby Township as our home base and regularly work throughout Macomb County and the wider metro area. If you are nearby, we can get to you.
Communities we serve include:
Call (586) 789-9445 to confirm service availability in your area and to schedule a visit.
Weak airflow from the vents, warm air coming out when the AC is running, a furnace that cycles on and off every few minutes, or unusual sounds like banging, rattling, or grinding are all reasons to call. A system that is working harder than it should to hold temperature is often close to a breakdown. The sooner we take a look, the better the chances of a straightforward repair.
Check your thermostat settings and make sure the system is set to the right mode and temperature. If the display is blank or unresponsive, check whether the circuit that feeds the unit has tripped. If none of that restores operation, call (586) 789-9445 and we will get a technician out as quickly as possible, including same-day when the schedule allows.
When you call, we gather the basics about your system and the problem you are seeing, then confirm a time to come out. The technician arrives, inspects the equipment, diagnoses the issue, and walks you through what was found and what the repair involves before any work begins. Once you approve the scope and pricing, we complete the job and make sure the system is running correctly before we leave.
Call us at (586) 789-9445 and describe what you are dealing with, whether that is a repair, a system replacement, or a new installation. We will ask a few questions about your equipment and schedule a time to come out. Pricing is explained before any work starts, with transparent pricing and no hidden fees on any HVAC job.
The main factors are the type of repair or installation needed, the age and condition of the existing equipment, and whether parts need to be sourced for less common systems. On a replacement, equipment size and any ductwork modifications can also affect the total. We explain all of it upfront so there are no surprises when the invoice arrives.
Yes. We handle HVAC repair, maintenance, and installation for office buildings, retail spaces, rental properties, and light commercial buildings throughout Shelby Township and Macomb County. Property managers and building owners can call the same number as residential customers and get the same responsive service.
We work on systems of all ages and configurations, including homes where the original equipment is well past its prime. Older systems sometimes present compatibility challenges when parts are no longer manufactured, and in those cases we give you an honest assessment of whether repair or replacement makes more sense for the long term.
We serve the broader Macomb County area, including Sterling Heights, Utica, Washington Township, Romeo, Macomb Township, Clinton Township, Chesterfield Township, and Troy. If you are in the surrounding region and are not sure whether we cover your location, call (586) 789-9445 and we will confirm availability.
It helps to know the make and model of your equipment if you can find it, a brief description of the problem or symptoms you have noticed, and a sense of how long the issue has been going on. Having that information ready lets us give you a more accurate time estimate and helps the technician arrive prepared.
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 never find a charge on your invoice that was not discussed and approved beforehand.
Davco Heating & Cooling is ready to help with heating and cooling repair, installation, and maintenance for homes and businesses across Shelby Township and Macomb County. Whether you need an emergency furnace repair, a new AC installation, or a seasonal tune-up, we are one call away.

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.
