Furnace Maintenance

We at Design Aire know that to have a healthy heater or furnace, it requires routine maintenance; especially during those summer months that your heater remains untouched. You don’t want a surprise when you finally turn it back on and there is a problem that keeps you from enjoying warmth and comfort when the temperature drops.

If you schedule service checkups for your heating systems, it allows you to avoid inconvenient outages that affect your entire family. Not only that, but your system will run more efficiently and last longer! View our furnace maintenance plans.

Furnace Installation & Replacement

If you have already had repairs done on your heater and it keeps breaking, or your regular maintenance still hasn’t made a difference in making it run well and run efficiently, it might be time to replace your system entirely. Design Aire technicians can provide a newer, more efficient heating system model and also install it for a competitive rate.

You may be someone who has relied on our team to repair and maintain your heater, or you may be a new customer who is not familiar with our services. Regardless, you can depend on the team at Design Aire to find and install a replacement heating system for you that you can rely on for years to come. Schedule your furnace installation appointment.

Common Heater Problems

Do any of the problems you’re having with your heater look familiar? Take a look at the common problems and the usual troubleshooting that might help diagnose the problem. Some of these solutions are things you can use yourself to troubleshoot your heater issues, but working with a knowledgeable technician can speed up the process in getting your heater working better faster.

Problem: If your heater is blowing cold air, a number of problems may be occurring. Perhaps your thermostat settings are incorrect, or you need a dirty air filter replaced because it is preventing the hot air from coming through properly. Actual problems that might be more serious include a faulty pilot light, ductwork leaks, or a dirty flame sensor.

Solution: To diagnose what is wrong, you might need to check your thermostat to see that it is set to “auto” instead of “on.” If the air filter is dirty, the grime may be triggering a safety feature that comes on to prevent overheating when air is blocked. If your flame sensor is dirty, you might notice bouts of warm air blowing, followed by the heater blowing cooler air.

These three things might be easier for you to diagnose because you can either see the problem – if the thermostat settings are wrong or the air filter looks dirty – or feel it in the case of the dirty flame sensor. However, a technician visit might be necessary to determine whether or not you have leaks in your ductwork which is causing the heater to work less efficiently.

Problem: If it has been several months since you started your heater and, upon first usage, you notice a bad smell, you might have some maintenance issues that can be remedied fairly quickly.

Solution: Some ways people stop a heater from smelling bad, or work to prevent it so it doesn’t happen in the first place, is to clean the heater, check the ductwork, and change the filter. With a maintenance plan from Design Aire, our technicians can regularly check your heater to make sure this problem does not occur later.

Customer Testimonials

Seth was our salesperson. He listened to our needs and provided the right product at the right price. The installation team arrived on time and went right to work.They worked with confidence and professionalism.We appreciated the care in protecting our floors and even the choice of how they went up on the roof indicated that they really did care. This company did what they said they would and certainly has our vote of appreciation and gratitude. We will happily recommend Design Aire to anyone.

Ken L.

One of the best companies to work with. My own profession is in a service industry and so I very much appreciate all the positive things about Design Aire.
The install crew arrived right on time and took exactly how much time they said they would to complete the job. The work was done well, the crew cleaned up after themselves, and were very pleasant. Seth in the office was extremely in-tune to our needs and very responsive.
I would highly recommend Design Aire.

Heather H.

Our new HVAC system was installed yesterday and we could not be happier. From quote to completion the process was great! 100% would recommend!

Greg H.

We have used Design Aire for both a new furnace two years ago and a new AC unit this summer. Everything was done very professionally and quickly. I would not hesitate to recommend them to anyone needing any type of HVAC work done.

Sean K.

Design Aire was the best choice from start to finish. Design Aire gave me the best price with the most detailed quote. The service technicians were very friendly and completed the job ahead of time. I highly recommend Design Aire.

John K.

We've used them for our old house and our new house. They are honest, friendly, professional and affordable. We felt lucky to find them.

Maddy R.

I was very impressed with Design Aire. They were timely and did an outstanding job with the installation of my new furnace. They had great communication and went above and beyond. I would highly recommend them to friends and family. Thank you so much Seth and Design Aire for making this an effortless transaction. VERY PLEASED!

Jonny M.

Design Aire sent a salesman to plan the system, and just a couple of days later sent the installers to remove the old system and install the new one. Everything happened when they said it would and the system performs as they said it would. All of the Design Aire staff were courteous, the work was performed efficiently and neatly, and they left the area cleaner than they found it. This is the second unit Design Aire has installed for us, and I have no need to look elsewhere.
