Gas smell, burning smell or no heat?

Heating and cooling guides

  • HVAC

    Heat pump or gas furnace for a Middle Tennessee home?

    Both work in Middle Tennessee, and what the house already has usually decides it. A heat pump heats and cools with one system and runs efficiently through most of the winter, with backup heat for the coldest nights. A gas furnace's output doesn't drop in the cold, but it needs gas service and a separate unit for cooling.

  • HVAC

    What does "emergency heat" mean on a heat pump thermostat?

    Emergency heat is a thermostat setting that shuts off your heat pump's outdoor unit and heats the house with backup heat alone, usually electric heat strips or a gas furnace. It's mainly for when the heat pump itself isn't working. Heat strips cost more to run than a working heat pump, so switch back once it's repaired.

  • HVAC

    Why is my AC running but not cooling?

    The usual causes are a clogged air filter, a thermostat set wrong, an outdoor unit that has stopped, a frozen indoor coil or low refrigerant. Check the thermostat, the filter and whether the outdoor unit is running, including its breaker. If they all look right and the house still won't cool, call an HVAC technician.

Heating and cooling questions

Who does the HVAC work?

HVAC work is done by licensed and insured techs. One call covers plumbing, heating and air, and electrical.

Do you install ductless mini-splits?

Yes. A mini-split heats and cools a room or zone without ductwork, which suits additions, garages, bonus rooms and older homes without ducts. We'll look at the space and give you a firm price before any work starts.

What is a package unit, and do you install them?

Yes, we install package units. A package unit puts the heating and cooling equipment in one cabinet outside, instead of splitting it between an outdoor unit and an indoor unit. They're common where there's no room inside for equipment, and on many commercial roofs.

My AC stopped cooling. What should I check first?

Make sure the thermostat is set to cool and below the room temperature, check the breakers for the indoor and outdoor units, and look at the air filter. If you see ice on the copper lines (the line set) or the indoor unit, turn cooling off and run the fan only so it can thaw. Then call or text (615) 426-9344.

The heat went out in a freeze. What should I do?

Check that the thermostat is set to heat and that the furnace switch and breaker are on. To protect your pipes, open the cabinet doors under sinks on outside walls and let those faucets drip. Never heat the house with an oven, stove or grill. Then call or text (615) 426-9344. We work Monday to Friday, 8 a.m. to 5 p.m.

How often should heating and cooling be serviced?

Once a year for each system is a common rule: cooling in spring and heating in fall. A heat pump does both jobs, so it often gets checked twice a year. Change or clean the filter every 1 to 3 months, depending on the filter and your home.

Do you do HVAC for new construction and renovations?

Yes. HVAC rough-in and trim-out for new homes, additions and remodels, coordinated with the plumbing and electrical. See new construction for builders and plumbing, HVAC and electrical for renovations.

Is the diagnostic visit free for heating and cooling?

Yes. We come look, find the cause and explain it in plain words, and you'll get a firm price before any work starts.

Work that holds.
