Stage detailsWhy choose us
We understand your concerns — and have answers
What are you paying $10-20K for?
You pay for a clear scope, proven equipment, and a detailed specification without unnecessary extras.
More details
Why it matters
Fear: I'll be deceived without knowing it
Can't distinguish brands, systems, configurations. Afraid of being sold unnecessary extras. Can't verify the solution myself.
How we solve it:
We explain each system element in simple terms. Show alternatives and analogues. Provide detailed specifications with explanations.
What happens if you choose the wrong system?
The right decision is made before renovation: we design the system in advance and align it with every contractor.
More details
Why it matters
Fear: this is a 10-15 year decision, and I'm not confident
Ventilation is built into the house. Rework = destroy the renovation. System replacement is almost impossible.
How we solve it:
We design the system before renovation starts. Coordinate with your designer and builders. Reserve technical options for future changes.
Why is the effect of ventilation not always obvious right away?
The effect shows up through sleep, comfort, and the absence of stuffiness, and we explain it with numbers and real cases.
More details
Why it matters
Fear: what if I don't feel the difference
Air is not a 'visible' product. Hard to feel the difference immediately. Effect is explained with numbers, not sensations.
How we solve it:
We show real cases with reviews. Explain what will change: sleep, no stuffiness, less dust. Guarantee results in the contract.
How will the solution affect your family's health and comfort?
We shape the system around noise, humidity, and living patterns so comfort supports your family’s health.
More details
Why it matters
Fear: I'll make a decision that everyone will pay for
Kids, sleep, allergies, humidity. Fear of making it worse (noise, drafts, cold). Fear of hidden problems in 1-2 years.
How we solve it:
We design considering noise and comfort. Use proven equipment. Provide warranty on work and equipment.
What happens if the system breaks?
Ventall has in-house service, warranty, and maintenance agreements, so the client is not left alone with the system.
More details
Why it matters
Fear: I'll be left alone with the problem
Who will service it? Will the company disappear? Dependence on one contractor.
How we solve it:
9 years in the market, 1000+ systems. Own service department. Maintenance contract with fixed terms.
What does the system consist of?
A typical system includes a ventilation unit, ductwork, grilles, air conditioning, and automation depending on the project.
What the system includes
Ventilation unit
Heart of the system — provides fresh air supply and exhaust. Often with heat recovery for savings.
Ductwork
Galvanized ducts through which air moves between the unit and rooms. Sealed connections.
Grilles and diffusers
Visible interior elements — air enters/exits through them. Can be adjustable.
Air conditioner
Air cooling/heating. Ducted (concealed) or wall-mounted (visible) — depends on the project.
Automation
System control: CO₂ sensors, humidity, timers, WiFi remote. Comfort without extra actions.
