HVAC repair that looks at the whole system
Your furnace and your air conditioner are not two separate machines. In most homes they share one blower, one filter, one thermostat and one set of ducts. So "the AC is not cooling" can start at the furnace, and a house that heats unevenly may have nothing wrong with the furnace at all. Maverick Heating and Cooling has handled heating and cooling repair across Oakland County for 7 years, and every call starts with working out where the fault really is.
We are a family-owned business with a crew of four. We arrive when we said we would, we test before we guess, and we explain what failed, your options and what each one costs before any repair starts. If the fix is a filter or a thermostat setting, we will tell you. Every repair is backed by our 100% satisfaction guarantee.
What to watch for
Not sure which part is the problem? Start here
These symptoms could come from several places in the system. Here is what each one usually points to.
Nothing runs and the thermostat is blank
Often it is dead batteries. If not, a safety switch on the drain may have cut the power to stop an overflow, or a small fuse on the control board has blown. The equipment itself may be fine.
Air comes out, but not hot or cold
The blower is working and the part that heats or cools is not. In winter that points to ignition or a safety shutting the burners off. In summer it usually points to the outdoor unit.
One room is always hotter or colder
This is rarely the furnace or the air conditioner. Look to the ducts: a run that has come apart, a crushed flexible duct, a closed damper or too little return air from that room.
Water on the floor by the furnace
In summer, the cooling coil above the furnace makes water and a blocked drain sends it onto the floor. In winter, a high-efficiency furnace makes water of its own. Either way it is a drain problem first.
System keeps turning on and off
Short cycling happens in both seasons, and the shared cause is usually airflow: a clogged filter, blocked returns or a dirty coil. A thermostat in a bad spot can also do it.
Weak air from every vent
When every room is weak, suspect what they all share: the filter, the blower motor or its capacitor, a coil packed with dust, or in summer a coil frozen into a block of ice.
What we do
Heating and cooling problems we repair in Oakland County
We work on most makes and models. These are the faults that sit between the furnace and the air conditioner, where they are easy to miss.
Thermostats and control wiring
Blank screens, wrong readings, a system that ignores the setting. We test the thermostat, its wiring and the fuse that protects them before blaming the equipment.
Blower motors and capacitors
One blower moves the air for both heating and cooling, so when it fails you lose both. We test the motor, its capacitor and the control that runs it.
Airflow restrictions
Clogged filters, dirty indoor coils, blocked returns and closed dampers. Low airflow overheats a furnace in winter and freezes a cooling coil in summer.
Duct leaks and loose connections
Ducts that have separated, joints that leak into the attic or basement and flexible runs that are kinked. We find where the air is going and fix it.
Drains, pumps and float switches
Clogged condensate lines, failed pumps and the safety switches that shut the system down when water backs up. Cleared, tested and put back in service.
Electrical and control faults
Tripped breakers, burnt contactors, loose connections and failed control boards. We read the fault codes, then test to confirm which part actually failed.
Heating problem or cooling problem? Where to go next
If you already know which side has quit, these pages go deeper. No heat, cold air from the vents or a furnace that lights and shuts off: read furnace repair. Warm air in summer, ice on the lines or an outdoor unit that hums but will not start: that is air conditioner repair. We do not work on boilers or radiators.
Some systems do both jobs with one piece of equipment. If yours heats and cools with an outdoor unit that runs all year, start with heat pump service. If you have wall-mounted units and no ducts, see ductless mini-split repair. And if you cannot tell, that is fine. You only need one HVAC contractor for all of it. Call 248-930-2080, describe what the system is doing, and we will take it from there.
When to stop and make a different call first
If you smell gas, leave the house right away and do not flip switches or look for the leak. Call 911 and your gas utility from outside. If a carbon monoxide alarm sounds, get everyone outside into fresh air and call 911. If a breaker keeps tripping, leave it off. Once the house is safe to go back into, call us and we will find the cause.
What to check before you call an HVAC technician
Plenty of service calls end at one of these. All of them are safe for a homeowner and none needs a tool. Mention what you tried when you call, because it shortens the diagnosis. Stop there, though. Refrigerant, gas valves, venting and anything behind an electrical panel are not do-it-yourself jobs.
- Thermostat set to HEAT or COOL, not OFF, with the fan on AUTO and fresh batteries
- The filter, since a clogged one can shut down a furnace or freeze an air conditioner
- Breakers for the furnace and the outdoor unit, and the furnace switch. Reset a tripped breaker once, no more
- Supply vents and return grilles open and clear of rugs, furniture and curtains
- The outdoor unit clear of leaves, snow and anything stacked against it
- Ice on the copper lines: switch cooling off and set the fan to ON until it thaws
How we diagnose an HVAC problem
We work from the things everything shares to the things only one side uses. First, is the thermostat asking for heat or cooling, and is that signal reaching the equipment? Then, is air moving the way it should through the filter, blower, coil and ducts? Only after that do we test the parts that make the heat or the cold. That order rules out the simple causes before anyone talks about expensive parts.
It also keeps the same repair from being done twice. A cooling coil that keeps icing over or a furnace safety switch that keeps tripping is usually a symptom. Something upstream, most often poor airflow, is behind it. We repair what failed and tell you what caused it, so you can deal with that too.
Repair or replace the whole system?
Most of what we find is repairable. On equipment that is still fairly young and has been reliable, fixing it is the sensible choice. Furnaces typically last 15 to 20 years, and air conditioners often somewhat less. A widely used rule of thumb: once a single repair would cost more than half the price of new equipment, replacement deserves a hard look.
Age alone is not a reason to replace anything. What matters is the pattern: several repairs in a couple of years, or an older air conditioner that runs on R-22, a refrigerant no longer made or imported in this country. We give you the repair price and our honest opinion, and the decision stays with you.

Why is my HVAC system not working?
Most often it is something small that the heating and cooling sides share: a thermostat with dead batteries or the wrong setting, a clogged filter, a tripped breaker or a drain safety switch that has shut the system off. Check those four first. If they are all fine, the fault is likely inside the equipment, such as an igniter, a capacitor, a motor or a control board, and it takes testing to pin down.
How do I know if my thermostat is the problem?
A blank screen, a room temperature that is clearly wrong or a system that ignores a changed setting all point to the thermostat. Replace the batteries and make sure it is set to HEAT or COOL. If the screen stays blank with new batteries, the thermostat may not be getting power from the furnace, which is a different fault. We test both ends before replacing anything.
Why is one room hotter or colder than the rest of the house?
It is usually the ductwork, not the equipment. The duct run to that room may have come loose, be crushed or leak along the way, or the room may not have enough return air. Rooms over a garage or at the end of a long run are the usual suspects. Closing vents elsewhere to push more air there tends to backfire, because it raises pressure in the ducts and makes leaks worse.
How much does HVAC repair cost in Oakland County?
It depends on which part failed and how hard it is to reach. Clearing a drain or replacing a capacitor is a small job. A blower motor, a control board or a refrigerant leak costs more. Nobody can give an honest number without seeing the system. What we can tell you is the order: we diagnose it, explain it and give you the price before the repair starts. Call 248-930-2080.
Why is my HVAC system so loud?
The kind of noise tells you a lot. Squealing or grinding usually comes from a motor or its bearings. Rattling is often a loose panel or duct. A loud hum or buzz from the outdoor unit suggests an electrical part that is struggling. Whistling at the vents often means the system is short of air. A new noise is worth a call before the part fails completely.
What if my heating or cooling fails in dangerous weather?
Call 248-930-2080 and tell us what is happening, including the temperature in the house and whether anyone there is very young, elderly or unwell. We will tell you honestly how soon we can be there. Our page on emergency HVAC repair covers what to do in the meantime.
