Follow the air through your house. We keep every stop comfortable.
Nashville HVAC repairs, installs and tunes heating, cooling, ductwork and air quality for homes and businesses across Middle Tennessee. Tap a station to follow one breath of air around the loop.
You ask for comfort
The thermostat compares the room with your setting and calls for cooling. One that sits in the sun or reads a few degrees off makes the whole system work harder than it should.
The thermostat compares the room with your setting and calls for heat. A drafty spot, a weak battery or an old dial can leave rooms too warm or too cold.
The house breathes in
Air is pulled back through the return grille and across the filter before it reaches the equipment. A clogged filter starves the system of air, which costs comfort and can damage parts.
Air is pulled back through the return grille and across the filter before it reaches the equipment. The same filter protects the furnace and blower, so a dirty one is trouble in winter too.
The blower moves it all
The blower pushes the air across the coil and out into the ducts. When its motor or capacitor weakens, the far rooms feel it first and the system gets louder.

Where the temperature changes
Refrigerant in the indoor coil absorbs heat and moisture from the passing air, so it leaves cooler and drier. A dirty coil, low refrigerant or a clogged drain is where cooling problems often start.
A furnace burns gas in a sealed heat exchanger, or a heat pump coil or electric element adds heat, and the air that passes over it leaves warm. Dirty burners, weak ignition and cracked exchangers are what we look for.
Ducts carry the work
Supply ducts carry the cooled air to every room. When they leak, kink or run through a hot attic without insulation, a share of the work never reaches you.

Registers mix the room
Registers spread the air across the room while the return pulls it back, so the space mixes evenly. Blocked vents and rooms with no return path are classic hot and cold spots.

Heat goes in or out here
The outdoor unit carries the heat the coil collected out of the house and releases it to the outside air. Keep it clear of leaves, grass and clutter so it can breathe.
A heat pump pulls heat from the outdoor air, even on a cold day, and carries it inside. With a furnace and a separate air conditioner, the outdoor unit simply rests in winter.

The house is one system.
A furnace, an air conditioner and a set of ducts do not work alone. We measure the whole loop, so the fix is the cause and not a guess.
We measure first
Airflow, temperature split, static pressure and electrical readings tell us what is wrong, so you pay to fix the cause and not a guess.
The whole system, not one part
Equipment, ducts, filters and controls work as a team. We look at the house around the unit, because that is where comfort is won or lost.
A written plan and price
Equipment, labor, extras and the schedule are spelled out before work starts, so you know exactly what the price includes.
Honest about repair or replace
If a repair makes sense, we say so. If a system is near the end of its life, we show you the numbers and let you decide.
A clean, careful visit
Drop cloths, shoe covers and a tidy truck. We explain what we did, show you the old parts and leave the area cleaner than we found it.
A real person to call
Call or text and a real person answers. Photos of the unit, the model label or the problem help us come prepared.
A measured visit, in a set order.
Eight checks from the filter to the thermostat. Run the clipboard to see what we look at and why each reading matters.
- Filter and airflowWe check the filter and measure airflow across the system.Clean or swap
- Temperature splitThe difference between the air going in and coming out shows how hard the system is working.Typically 15 to 20 degrees
- Static pressureHow hard the blower pushes against the ducts. Too high points to restrictions.Often under 0.5 in. wc
- Coil and drainA dirty coil or a clogged drain line is a common cause of water and warm air.Clear and flowing
- Refrigerant and pressuresReadings are compared with the maker's targets for the day.Within range
- ElectricalAmp draw, capacitors, contactors and wiring connections are tested and tightened.Tested and tight
- Burners and heat exchangerFlame, ignition, venting and the exchanger are inspected before the heating season.Clean flame, clear vent
- Thermostat and settingsCalibration, schedule and batteries are checked against what the house needs.Calibrated
A tune-up is a measured visit, not a quick look. The clipboard is the order we work in, and the readings go in your report so you can compare year to year.
- Readings written in your report, not just said out loud
- Photos of anything we find, so you can see it too
- A plain-English summary and what to watch next year

What HVAC services do you offer?
We repair, install and replace air conditioners, furnaces, heat pumps and ductless mini-splits, and we handle ductwork, indoor air quality, thermostats, tune-ups and commercial systems. Every service has its own page with details, steps and answers.
How do I get a price?
Fill in the form on any page, or call or text 615-431-3789. Photos of the unit and its label help us come prepared. Repairs are priced after a diagnosis, and replacements after a short visit, so the written price covers equipment, labor and extras.
How much does a new HVAC system cost?
It depends on the size, the efficiency, the type of equipment and what the ducts need. Two houses of the same size can price differently. Our Tonnage Finder gives a planning size, and a visit gives you a firm written price with the options side by side.
Should I repair or replace my system?
A repair makes sense when the system is in its middle years and the fix is small compared with a new one. A big repair on an old or failing system is usually money better spent on replacement. We show you both options in writing, and our Life Clock shows where your equipment sits in its typical life.
What size system does my house need?
Size depends on far more than square footage: insulation, windows, sun, ducts and how people use the house. An oversized system cools fast, shuts off early and leaves the air humid. We calculate the load instead of copying the old unit, and our Tonnage Finder gives you a starting range.
How often should I have my system serviced?
Once a year for each system is a good habit: cooling in spring and heating in fall. A tune-up cleans, measures and tests, so small problems are found before they become breakdowns. A maintenance plan puts it on a schedule.
My AC is not cooling. What should I check first?
Check that the thermostat is set to cool and has power, replace a dirty filter, make sure the breaker has not tripped and look for leaves or clutter around the outdoor unit. If the air is still warm, or ice has formed on the lines, turn it off and call us.
Why are some rooms too hot or too cold?
The usual causes are duct leaks, long or undersized runs, missing return air, a hot attic and sun on big windows. A technician can measure airflow and pressure to find the cause. Our Comfort Map shows how these issues change the rooms in a house.
