John Henry's Plumbing, Heating, Air, and Electrical is a leading provider of furnace maintenance in Waverly, NE. Winters in Nebraska can get extremely cold, and it is the worst time for your furnace to decide to stop working. The best way to prevent shutdowns during the coldest time of the year is with routine HVAC maintenance.

We recommend you schedule an appointment once in the spring before you switch to your air conditioner, and again in the fall before you turn on your heat. Our experienced technicians can inspect your furnace and make sure it’s working efficiently and identify potential problems before they happen.

"Kaleb was extremely proficient and professional. He communicated all the work he did and made several recommendations which were greatly appreciated."

When to Call for Furnace Maintenance

The average furnace lasts between 15 and 20 years with proper maintenance. Even with the best of care, your unit will likely need repairs at some point.

The most obvious time to call for furnace maintenance is when the unit won’t turn on or it’s blowing cold air, but there are plenty of warning signs to look for that indicate you might have a future problem.

While you may be tempted to put off small repairs, it’s best to address them immediately to avoid more costly problems later. Older units are more susceptible to issues and you may see an increase in repairs once your warranty has expired.

Calling a professional HVAC technician for maintenance helps keep your system running as long as possible.

Some of the warning signs you need to schedule an appointment for an HVAC tune-up include:

Poor air flow
Increased utility bills
Loud noises when the unit turns on
Inefficient heating
Odd smells
Faulty thermostats

The Best Choice for HVAC Maintenance in Waverly

There are a few things you can do on your own to keep your furnace running efficiently, such as changing the filters and making sure the outside unit is clean and free from dirt and foliage.

An HVAC technician inspects and replaces any worn or damaged moving parts and offers advice on any potential upgrades. For more than two decades, we’ve provided reliable heating and air service to our customers in Waverly.

We offer a 100% satisfaction guarantee, so if you’re not completely happy with our work we will make it right.

Can Regular Tune-Ups Improve My Indoor Air Quality?

Absolutely. During maintenance visits, technicians replace filters, remove debris, and ensure proper airflow. These measures help reduce dust, allergens, and other pollutants circulating through your home, contributing to cleaner, healthier indoor air.

What If My Furnace Is Older or Showing Signs of Wear?

Routine maintenance is especially critical for older systems. Your technician can recommend adjustments, minor repairs, or even parts replacements that may extend the furnace’s lifespan and prevent unexpected breakdowns.

Is a Maintenance Plan Worth It?

In many cases, yes. Maintenance plans offer scheduled tune-ups, priority service, and discounts on repairs. They help keep your HVAC system in peak condition year-round, often saving you money and ensuring peace of mind.

On 9January2025 our annual check of the HVAC system was performed by John Henry's service engineer Carson. He arrived and performed the necessary tests and parts replacement in a timely manner. We are happy knowing that we can expect continued safe operation of this system for the future and will count on the service of John Henry's in the years ahead.

I wish that i had known of this business years ago! Person answering their office phone was very nice - I was surprised when I was told someone would be out later that same day! Ian was competent, friendly and professional. He was easy to talk to - fully understood the issue, and explained the necessary work and associated cost. Everything was entirely "above board;" no "extra" fees of any sort. Ian was efficient and completed the project in about the time he had estimated, thoroughly cleaned the area, and reviewed the finished project with me. I am sure there are competent plumbers in town - but John Henry's customer service from initial phone call until the time Ian pulled out of the driveway is very hard to find in our time. Highly recommend.

Due to having completed a few renovations in my home, I am somewhat familiar with the plumbing layout. I was up against an obstruction that my power snake just wouldn’t go through from the upstairs bathroom. I finally had to call in the professionals. Enter John Henry’s Plumbing people Alec and Samara. I hope I got their names right. I was able to provide a lot of information to them about what had been done already that they were free to verify. They did verify that the downstairs bathroom line was clear to the street. The upstairs toilet line ended up having huge root intrusion. That was found initially with the video inspection but further evidence continued to come out as larger, more powerful snakes came into play. That is one downright effective team right there. They had all the equipment they needed to properly diagnose the issue including a variety of snake sizes and video. Then kept after it until they were positive they had that line clear. I am very impressed and very grateful! I had to call in the pro’s and it was worth every dollar! Call John Henry’s

Thanks John Henry’s for getting the tech, Weston, out to my home so promptly. There was a sound coming from our humidifier. Weston figured out the problem and took care of it immediately.We also recently had the tech, Shawn, out for a dryer vent cleaning. I couldn’t believe how easy it is to have that done.I highly recommend John Henry’s for your heating and air conditioning needs.

John Henry's staff is professional. They do not try to hard sell me on anything. They advise me of options. Immediate issues get taken care of in a prompt manner. They continue to consult with me over time as I upgrade my town home in Northeast Lincoln. The place had all the original fixtures from 2015 when I moved in less than three years ago. I have a plan now with my budget. I expect to have the place where it should be within the next year. Their guidance is invaluable.

Great service from the tech. getting our water heater replaced. Not a fun day cleaning up water from the old unit that started leaking. The texh covered what needed to be done and the cost before starting the project. Just one of the unfortunate things a homeowner gets to deal with owning a home. Glad to have hot water in the pipes again. Thanks for the great service from start to finish.

John Henry's is my go-to for plumbing and HVAC in Lincoln. They have good availability, don't charge extra for weekend service calls, have always been prompt, and do a great job fixing my problems the first time. I've never been pressured with an up-sell for a product I don't need, either. Their techs have also been great showing me how to do simple repairs and maintenance on my first home so I can avoid a service call in the future.

John Henry's sent out a two person team to tackle a sewer line clog. They were able to quickly find and fix the issue. They were also kind enough to explain and answer all of mine and my 7 year old sons questions. They were super friendly and nonweldable. If you have to call a plumber, its likely a bad day, but John Henry's team knocked it out of the park. If I need service again, they will be my first call.
