Super Helpful

I, of course waited until the last minute to schedule a furnace tune up in the fall of 2015. I had the day off and their schedule was full. But without hesitation they carved some time in their schedule and fit me in without even asking. The service I received was over the top friendly and helpful. When they were just about to leave they even handed me a pamphlet with small business owners they trust in our community. I have even had the opportunity to contact one of those on the list and again…super helpful.

Very nice and helpful!

Red Line always has our back. When we call, which can be frequent due to owning several properties, they always get us on the schedule quickly, treat us with respect and seem to be more reasonably priced than their competition.

Installer was on time and was careful to put down tarps on the carpet.

Steve is a good representative of your company as he does his job well and is very nice to customers.

Professional Company- Affordable Prices

RED LINE Heating & Cooling is a professional company; they were the only ones around that had a specific product I needed for my furnace. They provided me with a accurate quote and serviced me within a reasonable time frame. RED LINE Heating & Cooling technicians’ were neat, timely, knowledgeable and friendly. In comparison to other companies in the area RED LINE Heating & Cooling were very affordable – other businesses’ costs or prices are doubled of what RED LINE Heating & Cooling are offering!

Good workers, solved my issues.

Red Line Heating & Cooling came back three times for some minor things that were happening with my furnace. The third time they came back they figured out that there was a lot of debris in the motor of the furnace.

They ended up taking apart the motor and cleaned it all out and put it back together and I haven’t had any issues since.

I had them come in twice previously, once to replace a coupling on the water heater and another time to replace the water heater all together. They are polite and courteous and pretty knowledgeable.

Solid AC and heating service.

We have had Red Line Heating & Cooling out to our home 3 times in the 3 years, once for the furnace, once on the air conditioner and once to work on both.

My only thing is when they first come to the door they don’t seem very friendly but they obviously do great work and very polite and professional. We have been happy with the work we received so far.

Great service and workers.

We bought a house that was built in the 1960’s and it had had one other furnace besides the original so we had Red Line Heating & Cooling install a new furnace. They did a great job, they didn’t scratch anything or damage anything and the got the work done and they even came for a yearly checkup for maintenance on the unit. The workers who came were very polite and friendly, service couldn’t have been better.

Great service and maintenance.

I have been very pleased with Red Line Heating and Cooling. I got both my air conditioner and furnace from them and they also proved my maintenance and check ups. They have been nothing but polite kind and courteous while I have had them. I would definitely recommend them to other people. Very good company.
