Very personable and patient!

Both technicians that came to our home were great! They were very personable, and very patient. My mother in-law has a hard time with her English, as it is her second language, but they were both very patient with her, and made sure she understood everything that needed to be done. On their customer service alone I would recommend this company. We live in an old 1980's trailer which made it hard to find parts needed to fix our heating system, but they did all the research they could to try and find the parts needed. I am so glad I decided to call Mainstream Electric and will continue to use their services in the future.

Great seasonal service!

Great seasonal service today on our furnace and air handler/AC unit. Matt Miller did a very courteous and professional job describing all that he was doing and did and made additional recommendations on future service and care. He was very knowledgeable and had great interpersonal skills. We have used Mainstream for other projects as well and have always been satisfied with the work performed. I can say with honesty that they have not always been the cheapest, but they have always been the best. 'Good service is not cheap and cheap service is not good.' If you ever need a plumber, electrician or HVAC specialist, I highly recommend Mainstream.

Knowledgeable, fast and efficient!

Norm and Adam were knowledgeable, fast and efficient when installing my new furnace. They had answers to all of my questions and explained everything they were doing. I would recommend Mainstream Electric to anyone needing help with their heating. They even assisted me in getting financing for my furnace. Thanks to everyone at Mainstream Electric you are great!

Above & Beyond

Technician Steve, was very thorough in his investigation. Went above what I asked for, we had a black water flood and I was just asking to have the toilet and sink reinstalled. He put his camera through my sewer system to make sure that we were not going to have future issues. He made sure that I was able to see what he saw. It was educational to say the least and he was great at explaining what was in there. Feel very safe using his services and do not feel that he is taking advantage in any way. Highly recommend Steve!!

What are Common Signs of a Furnace in Need of Repair?

Even when your home furnace system is still heating your home, there are common warning signs Mainstream Electric, Heating, Cooling, & Plumbing knows to look for. If you notice any of the following, a heating system problem may be present and it's time to call the professionals at Mainstream Electric, Heating, Cooling, & Plumbing for a broken furnace repair:

Is Your Furnace On But Not Producing Enough Heat?

Is your home furnace unit on but not giving off enough heat on a cold Washington winter's day? Your furnace may have a clogged, dirty air filter, which is one of the main causes of a furnace breakdown.

Is Your Home's Furnace Making Drastic Temperature Changes or Not Heating at All?

Your gas furnace could be experiencing a thermostat failure or malfunction. A faulty thermostat can lead to fan, pilot light, power, or gas issues & ruin the comfort of your home. Restore comfort levels by giving Mainstream Electric, Heating, Cooling, & Plumbing a call to get a furnace repair diagnostic before any work is done.

Home Furnace Systems in WA are Prone to Cracking During Seasonal Changes in Temperature

Over time, changes in temperature may cause your gas furnace's heat exchanger to crack, a potentially very dangerous situation, as cracks can allow carbon monoxide to seep into your home. Call a Mainstream Electric, Heating, Cooling, & Plumbing furnace expert right away to have your home's furnace professionally diagnosed & repaired.

Experiencing Pilot Light or Electric Ignition Issues?

If your furnace isn't turning on at all, a common explanation is an issue with your pilot light or electronic ignition. Older furnace heating systems with a pilot light that continues to go out may seem like a small problem, but it can actually be wasting a lot of money and cause an increase on your monthly Spokane Valley, Washington gas bill. As the weather gets colder, a flickering pilot light will make your furnace work harder and cause unnecessary wear & tear, and a much more costly bill.

No matter the problem, our Washington furnace repair technicians will determine what needs to be repaired before any work is done, so you will know exactly what solution is best for your home furnace system.
