Stories From Neighbors Across Waterloo Region

We measure our success by the comfort and peace of mind of our customers. Here is what real homeowners say about working with ON TIME.

AC Repair

"Our central air conditioner completely died during a 35°C heatwave on a Sunday afternoon. We called ON TIME and a technician was at our door within 45 minutes. He diagnosed a blown capacitor, replaced it from his stocked truck, and had ice-cold air flowing in under an hour. Fair pricing and zero emergency gouging!"

David & Sarah Becker
Kitchener (Eastwood Area)
Furnace Install

"We replaced our 22-year-old furnace with a two-stage variable speed unit. The ON TIME team did proper heat loss calculations, laid down floor runners everywhere, and helped us claim our energy efficiency rebates. Our heating bills dropped by over 30% this winter!"

RM
Robert MacIntyre
Waterloo (Laurelwood)
Drain & Plumbing

"Our basement floor drain started overflowing with sewer water at 9 PM on a holiday weekend. ON TIME dispatched a master plumber who snaked the mainline, ran a fiber-optic camera to show us the tree root intrusion, and hydro-jetted the entire pipe clear. Absolute lifesavers!"

EL
Elena & Marco Rossi
Cambridge (Galt Area)
Heat Pump

"We added a cold-climate heat pump with 3 multi-split indoor heads for our second floor bedrooms. The install was super neat with concealed line-hide conduits and zero mess. The bedrooms are now perfectly temperature balanced year-round and whisper quiet."

Karen Chen
Guelph (South End)
Gas Fitting

"We had ON TIME run a natural gas line out to our back patio for our BBQ and fire table, plus hook up a new gas range in our renovated kitchen. TSSA pressure tagged, clean black iron piping, and completed on the exact day promised. 10/10 service."

Jason Tremblay
Kitchener (Doon South)
Air Quality

"Both of our children suffer from dust and seasonal pollen allergies. ON TIME installed a whole-house HEPA bypass filter and steam humidifier directly onto our ductwork. The difference in indoor air freshness and sleep quality has been incredible!"

AS
Anita & Sunil Sharma
Waterloo (Beechwood)
Geothermal

"Finding technicians who actually understand ground-source geothermal systems is very hard. ON TIME came out with a purge cart, flushed our ground loop, checked glycol levels, and optimized our compressor staging. Top notch engineering expertise."

GH
Gordon Harrison
St. Jacobs Rural Area
Renovations

"We finished our basement and needed a 3-piece bathroom rough-in cut into the concrete slab plus ductwork relocated. ON TIME passed the city plumbing inspection on the first try with zero revisions. Clean, polite, and totally professional."

Maintenance

"We have been on their annual maintenance protection plan for 4 years now. They service our AC in May and our furnace in October. Punctual, honest, never push unneeded parts, and our equipment runs flawlessly. Highly recommended company!"
