Real reviews from customers across Metro Vancouver, covering heating, cooling, boiler and maintenance work.
“We live in Cyprus and have a rented commercial property in Vancouver. We had an issue with the VRF system two nights ago and called Vanheat Services for urgent help. Their crew showed up the very next day and fixed the rooftop unit very quickly. The price was also very reasonable. The Vanheat technicians were professional, reliable, and knowledgeable. We highly recommend Vanheat Services for commercial and strata properties.”
“VanHeat Services recently completed maintenance on four systems at our home: the AC, air handler, tankless water heater, and HRV. Shaun was very knowledgeable, professional, and thorough… VanHeat Services is now our go-to company for maintaining the heating, cooling, and ventilation systems in our home.”
“…the inspection was thorough enough to actually find another issue with the boiler system, which is required to keep the house warm in winter. Both issues were fixed within a few hours… I highly recommend this company if you are looking for quick service appointment and affordable price for parts or replacement.”
“Technician was prompt, professional and friendly. Cost for annual servicing of our furnace and tankless water heater was reasonable. We will definitely be calling them again next year.”
“Sean was amazing! Communicated all aspects of work. Thank you”

Signs Your Ducts May Need Repair
Duct problems often show up as comfort and airflow issues before anyone sees the ducts themselves.
Rooms That Never Feel Right
Some rooms stay colder in winter or warmer in summer than the rest of the home, even with the system running normally.
Weak Airflow at Some Registers
Vents that barely move air while others work well can point to a disconnected, crushed, restricted or poorly connected duct run.
Whistling or Rattling
Whistling at registers or rattling in duct runs can come from gaps, loose sections or restrictions.
Visible Damage
Disconnected, sagging, crushed or torn ducts in a basement, crawlspace, attic or garage, or ducts damaged during a renovation.
Condensation or Damaged Insulation
Sweating ducts or torn insulation on ducts in unconditioned spaces, especially during cooling season.
Rising Bills or a Struggling System
A system that runs longer than it used to can be one sign of a duct problem, among other possible causes.

Airflow Problem Diagnosis
Finding why a room gets weak airflow, whether from a disconnected, crushed, restricted or poorly connected duct run, a closed damper or a blocked return.
Duct Repair or Duct Cleaning?
They solve different problems. Repair and sealing fix leaks, gaps and damage that keep air from reaching your rooms. Cleaning removes debris from inside the ducts. The U.S. Environmental Protection Agency does not recommend routine duct cleaning, but suggests considering it when there is substantial visible mould growth inside hard-surface ducts or on other parts of the heating and cooling system, ducts infested with rodents or insects, or ducts clogged with excessive dust and debris. If you are not sure which you need, we start with an inspection.
Older Ductwork and Asbestos in BC
Homes built before 1990 are more likely to contain asbestos, and HealthLinkBC (File 32, Asbestos in Your Home) lists the insulation wrapped around furnace ducts and pipes as one place it can be found. You cannot always tell by looking, so suspect material should not be disturbed until a qualified professional has collected and tested a sample. Duct work near suspect material waits until it has been tested and, if needed, removed by a qualified asbestos abatement contractor.
Air Duct Repair Across Metro Vancouver
Serving homes, strata and commercial buildings across Metro Vancouver, the Lower Mainland and Squamish.
How Duct Repair Works
From inspection to the final airflow check.
1. Inspection
We inspect accessible duct runs, joints, boots and insulation, and check airflow at the registers to find where the problems are.
2. Written Quote
You receive a written quote for the recommended repairs, sealing or replacement before any work begins. Approved work is billed at the quoted price unless additional work is identified and separately authorized.
3. Repair and Sealing
Damaged sections are repaired or replaced, loose joints are reconnected and secured, and leaking connections are sealed.
4. Airflow Check
We run the system and check airflow at the affected registers, and walk you through what was done.
Properties We Work On
Duct work for residential, strata and commercial properties.
Homes and Townhouses
Duct repair, sealing and replacement in basements, crawlspaces, attics and finished ceilings, including older homes and homes after renovations.
Strata Suites
Work inside individual suites and townhouses with suite-level heating systems, coordinated with the owner and strata council.
Commercial Buildings
Ductwork inspection, repair and changes as part of commercial HVAC service and replacement projects, quoted after a site assessment. See commercial HVAC; commercial duct cleaning is a separate service.
Air Duct Repair Cost in Vancouver
Duct work varies too much from home to home for a fixed price. Cost depends on how many joints or sections need work, the length of the runs, and whether the ducts are reachable in a basement or crawlspace or hidden behind finished ceilings and walls. Duct repair and sealing are quoted in writing after an on-site assessment, before work begins. Ductwork for a new furnace or heat pump is included in the installation quote, which follows a free in-home estimate. Commercial and strata projects are quoted after a site assessment.
Air Duct Repair Vancouver: FAQ
How much does air duct repair cost in Vancouver?
It depends on what the inspection finds: how many joints or sections need work, where the ducts run, and whether they are accessible in a basement, crawlspace, attic or ceiling. Duct repair and sealing are quoted in writing after an on-site assessment and before work begins. Duct replacement as part of a new furnace or heat pump installation is quoted in writing after a free in-home estimate, and commercial work after a site assessment.
Should I repair, seal or replace my ductwork?
Disconnected joints, crushed or torn sections and leaking connections can usually be repaired and sealed. Replacement makes more sense when large sections are damaged, the ducts are badly deteriorated, or the existing layout cannot deliver the airflow a new furnace or heat pump needs. We recommend an approach after inspecting the system.
Does sealing air ducts make a difference?
Sealing leaking joints and connections helps more of the heated or cooled air reach the rooms it is meant for, which can improve airflow and comfort. How much difference it makes depends on how leaky the ducts are and whether they run through unheated spaces such as crawlspaces, attics or garages.
Is duct repair the same as duct cleaning?
No. Duct repair and sealing fix leaks, gaps and damage that affect airflow. Duct cleaning removes debris from inside the ducts. The U.S. Environmental Protection Agency does not recommend routine duct cleaning, but suggests considering it when there is substantial visible mould growth inside hard-surface ducts or on other parts of the heating and cooling system, ducts infested with rodents or insects, or ducts clogged with excessive dust and debris. See our duct cleaning page for that service.
Can you change or replace ductwork when installing a new furnace or heat pump?
Yes. A new furnace or central heat pump needs ductwork that can move the right amount of air. During the in-home estimate we check the existing ducts, and any repairs, modifications or replacement sections needed are included in the written quote for the installation.
Do I need a permit for duct replacement?
It depends on the municipality and the scope of the work. Minor duct repairs and sealing may not need a permit, while larger duct alterations or replacements, especially those done as part of a new heating or cooling system, may fall under the permits for that work. We confirm the applicable permits before work begins.
Could my old ductwork contain asbestos?
It is possible in older homes. HealthLinkBC notes that homes built before 1990 are more likely to contain asbestos, including in insulation wrapped around furnace ducts or pipes. You cannot always tell by looking: do not disturb suspect material, and have a qualified professional collect and test a sample. Duct work near suspect material waits until it has been tested and, if needed, removed by a qualified asbestos abatement contractor.
Do you work on ducts in strata and commercial buildings?
Yes. We work on ductwork in homes, townhouses and strata suites, and on ductwork as part of commercial HVAC service and replacement projects. Commercial and strata projects are quoted in writing after a site assessment, coordinated with the property manager or strata council. Commercial duct cleaning is a separate service.
Rooms Too Hot, Too Cold or Too Quiet at the Vent?
Book a duct assessment. We find the leaks, gaps and damaged sections, and give you a written quote before any work begins.
