Seattle Furnace Installation & Replacement

Is it time for a new furnace? Call 206.792.7495 today and we will provide you with expert Seattle furnace installation and replacement at affordable prices. Your furnace won’t provide you with the heating efficiency you need with improper installation. Give us a call and we will send a professional technician to get the process started.

Your furnace is only as good as the installers that put it in your house and set it up, so if the installation element was lacking, your furnace may never realize its full potential. You may need frequent repairs or a full scale correction, and the overall lack of efficiency might result in higher heating bills than necessary. Don’t risk a poor quality installation by chasing deals or trying to save some money. Start with experienced professionals and you’ll have the best furnace possible.

Trouble with your furnace doesn’t necessarily mean you need to replace it. Ask about expert furnace repair today!

Signs Your Furnace Is Breaking Down

Every furnace starts showing signs that it is going to break down, before it actually does. These signs vary in size and scope, and sometimes they are quite subtle. Much of the time, the signs you see wouldn’t have caused a breakdown immediately, which is why it is so important to call for assistance. Some of the signs that your furnace is in decline include irregular heating or inability to reach the temperature you’ve set on the thermostat, loud noises or banging when the furnace is working, bad smells when it is working, or higher than average heating bills. If you notice one or more of these signs, call for professional attention. Foul smells coming from your gas furnace are an especially bad sign, as they can indicate a dangerous gas leak.

When Should I Have It Replaced?

Most furnaces last for up to 20 years if they are properly maintained, and if yours is reaching that limit, you may want to consider changing to a newer, more energy efficient model. Older furnaces will cost you more in monthly bills than a new furnace, and if you find that you’re paying for repairs regularly, having your furnace replaced just makes sense. You might also replace your furnace if you have been using a unit that runs on gas or oil, and want to upgrade to an electric unit.

Upgrade to a More Energy Efficient Furnace

One of the most common reasons a homeowner might choose to replace their furnace is to make their home more energy-efficient. It is widely known that gas furnaces are more efficient than electric, but did you know that a new electric furnace is more efficient than an oil-burning furnace? If you are looking to reduce your carbon footprint and lower your monthly heating bill, talk to one of Super Techs about your furnace installation options, and what type of heater is best for your home.

Gene’s Supr Techs also service boilers and other types of heaters!

Reputable Installation Is Key

When you do decide to have a new furnace installed, the quality of the installation will go a long way toward how well your furnace performs over its lifespan. This is true of gas, oil, and electric furnaces. If you run after the best deal in town or try to install it yourself, you may end up having to get it done over again when it malfunctions. Have it done right the first time, and you’ll have a heating system that never lets you down.

Even the best brand of furnace won’t last if it isn’t installed according to best industry practices. Call Gene Johnson Heating, Cooling, Plumbing and Electrical at 206.792.7495 in the Seattle, WA area for fast, efficient and effective furnace installation and replacement.

What Our Clients Say

Gene Johnson plumbing installed a new toilet for us, it was great working with them! Ishmael gave us estimates for various options, and we decided to buy our own toilet and have them come back to do the installation. Krystal did the install, and she was clean, efficient, very pleasant to work with, and the job was done quickly! It was also easy to schedule the work to be done. I would definitely work with them again!

– Lisa Henry

Another exceptional service call!…Alex was a true expert and he was very thorough and was patient while we went through our list of plumbing goals during this thorough full house inspection. He was able to give us some cost estimates on the spot. I certainly feel like I’m in the best hands and look forward to moving forward with our project.

– Ivan Archer

I had a new water heater installed with Gene Johnson this week and I was very happy with the whole experience. Eric Sams was my technician and he was incredibly knowledgeable and friendly and really took the time to explain my options to me. We have “unique” water heater systems in my place and he really knew what he was doing, I knew I could trust him. The installation was scheduled quickly and works/looks great!

– Ashley Curtin

Great experience with Branson! Very friendly, knowledgeable, and the quote was accurate. Needed shut-off valves installed on my house from the 40s, existing lines were galvanized steel, so that made things tricky. He outlined several options and recommendations, and we settled on something that will be compatible and easy to work with for future kitchen remodel plans. Will definitely be calling Gene Johnson again when it’s time to do more plumbing work!

– Brian Munn

I reached out to Gene Johnson regarding my radiant heating not working properly. They were able to come by within the next day to take a look. Tech Mike F was very knowledgeable and honest regarding next steps and questions my wife and I had. We proceeded to replace the Manifold and add a magnetic separator to my unit. Heat is now working! :)

– Phil Maaa

Prompt, informative, professional, friendly – very happy with service today.

– Francy M

Carlos was terrific!  He had the necessary parts on hand – he explained the problem, the solution, cleaned up after himself and now I don’t have water dripping under the sink!  Thank you Carlos!
