Indoor Air Quality & Comfort
Comfort is more than a number on the thermostat. Dust, humidity, uneven temperatures and tired ductwork all change how a house feels, and none of them are solved by turning the system down another degree. Quality Plumbing & Heating Inc. installs and services whole-home filtration, humidifiers, dehumidifiers, thermostats and the equipment around them throughout Indiana.

Whole-Home Filtration
Dust, pollen, mold spores and other common indoor pollutants collect in ductwork and then travel through the house every time the system runs. Portable units only treat the room they sit in. A whole-home filtration system treats the air moving through the entire house, and because it works with the equipment already installed, it also keeps that equipment cleaner. QPH sizes and installs whole-home filtration and services what is already in place, including filter checks during preventative maintenance visits.
- Whole-home filtration that treats every room the system serves.
- Help with dust, pollen and common household odors.
- Filter checks and replacement as part of scheduled maintenance.
- Cleaner air moving through the equipment as well as the house.

Humidity Control
Indiana gives a house both problems in the same year. Summers are humid enough that air that has been cooled still feels heavy, and winters are dry enough to leave static, cracking trim and irritated sinuses. A whole-home humidifier or dehumidifier works with the heating and cooling system rather than beside it, which is what makes it possible to hold the whole house at a comfortable level instead of chasing one room at a time. QPH installs and services both, and will tell you which one your home actually needs.
- Whole-home humidifiers for dry winter air.
- Whole-home dehumidifiers for humid summer months.
- Equipment that works with the existing heating and cooling system.
- Installation and ongoing service from the same team.

Comfort Problems Around the House
Some comfort complaints are not equipment failures at all. Hot and cold spots, rooms that never keep up, weak airflow at a register or a thermostat in the wrong place will make a perfectly good air conditioner or furnace look like the problem. QPH works on the parts of the system between the equipment and the room, including ducts and vents, registers, thermostats and ventilation, so the fix matches the actual cause. Where a room simply cannot be reached by the existing system, a ductless mini split is often the smaller and less invasive answer.
- Hot and cold spots from room to room.
- Ducts, vents and registers that are not delivering air.
- Thermostat placement, setup and replacement.
- Ventilation and airflow troubleshooting.

Frequently Asked Questions
Indoor Air Quality Questions
Filtration installed at the heating and cooling system so it treats the air moving through the whole house, rather than one room at a time.
It is the most direct way to reduce what is circulating through the ductwork, which is where most household dust and odors travel.
Many Indiana homes benefit from both across the year. We will look at the house and tell you which one to start with.
Usually airflow, ducting or thermostat placement rather than the equipment itself. It needs to be diagnosed at the house.
Yes. Thermostats are part of what our technicians install and service.
Filter checks and related equipment are part of what a preventative maintenance visit covers. Ask about a service plan if you would rather have it scheduled automatically.
