What we see in Oshawa

  • Older homes near downtown and the south end: small basements, older ductwork, chimneys, and sometimes leftover oil tanks or old boilers. Venting and chimney liners matter when equipment is replaced.
  • Rental homes and duplexes, including near the university: landlords need reliable equipment and quick repairs. We can quote replacements that keep tenants comfortable and maintenance low.
  • Newer north-end homes: builder-original furnaces and ACs reaching replacement age.
Tip: if you’re a landlord, a yearly furnace service and fresh CO alarm batteries are cheap insurance against a winter no-heat call.

I had a very positive experience with Ehsan from Aurora Star Tech. I hired him to perform maintenance and safety inspections on multiple gas furnaces and gas fireplaces, including some older and less common equipment. Ehsan was thorough and spent considerable time on each unit rather than rushing through the job. He cleaned and tested the equipment, took operating measurements, and communicated with me frequently throughout the service. I especially appreciated that he explained what he was checking, shared his findings and readings with me, and showed me how some of the older fireplaces operate. At the end of the visit, he completed an individual written maintenance and inspection report for each units, including key measurements and findings. I really value this kind of documentation for future maintenance. Overall, I found Ehsan knowledgeable, patient, communicative and conscientious. He took the time to do the work properly and to help me understand the condition of the equipment. I would be happy to use Aurora Star Tech again and highly recommend Ehsan and his company.

Ehsan was incredibly helpful in resolving our furnace issue. We thought we had a gas leak, but Ehsan investigated and determined that there fortunately no gas leak in our case. Instead, we had a thermostat signal issue which he resolved. Ehsan was very responsive and accommodating, and we will be using his services moving forward!

Eshan and his partner did a great job installing my AC unit. The installation was clean, efficient, and completed on time. Price stayed exactly as quoted with no hidden fees or surprise charges. I’m happy with the service and would definitely recommend Eshan to anyone looking for reliable HVAC work!

I had a leaky gas pipe behind my gas stove, and Ehsan took care of the repairs very promptly and professionally. He was friendly, knowledgeable, and patiently answered all the questions I had about the repair. Service quote was also very reasonably priced, and I was extremely satisfied with the service I was provided. I would 100% recommend him to anyone looking for a professional technician, and would definitely contact Ehsan again myself for any repairs in the future.
