We would become Ottawa’s most reliable contractors that could fix any furnace, boiler, water heater, or air conditioning system, and we would do it better than anybody else because of our absolute commitment to excellence.

New Customers See The Difference Right Away

Ottawa residents report having some problems with heating and air conditioning contractors, including:

Customers LOVE Our Transparent Pricing Options!

There are always multiple ways of fixing any heating or cooling system, ranging from “Band-Aid” fixes to full scale, “get your system performing like new” services — But most heating and air conditioning services act like there is just one EXPENSIVE fix, and they use pressure and even fear to get you to pay.

Ottawa Homeowners will NEVER have that kind of experience with J. D. Swallow.

 Trustindex verifies that the original source of the review is Google. JD Swallow installed a new gas-fired hot water heater for us. Andrew G. and Kevin F. were on time, friendly, and professional. They were careful to lay down mats to protect the floors as they moved the old water heater out and the new one in. They tidied as they worked, and the area was spotless upon completion of the installation. Another job well done by JD Swallow Heating & Cooling!

 Trustindex verifies that the original source of the review is Google. I recently contracted JD Swalllow to replace my leaky combi-core hot water heater. JDS were up front about their process and their pricing was very competitive which made my decision to hire them very easy (plus, they came highly recommended).  Thank you to the team - Jeremy, Germane, Jithin and Alex - for making the best of  returning my old tank and then installing the new one in a very tight space. And thank you to André as well who returned the next day to finalize a few things requiring his expertise. He also provided me with a lot of information on extending the life of my new HWH. I will keep using JD Swallow in the future and recommend them to anyone who asks.

 Trustindex verifies that the original source of the review is Google. Technicians that arrived were extremely professional and friendly.  They worked efficiently throughout the house and were very respectful of the areas they were working in.  What was even more impressive, was the way they interacted with my two dogs.  Would highly recommend!
