A maintenance visit has little to do with the filter. It is for safety and efficiency.

Updated: Oct 8, 2023

Now you might be thinking:

I know how to change a filter, why do I need maintenance? My system runs fine!

When our highly skilled technicians come for a regular maintenance appointment we are committed to thorough testing and maintenance of mechanical, performance, and safety systems. While a clean filter is very important to keep your family and your system safe, it is only one small part of keeping everything running great. Most HVAC manufacturers recommend yearly maintenance. We are going to discuss what is actually involved in your maintenance visit.

(Don't know how or where to change your air filter for your air conditioner or furnace system? That's ok. We can help you choose the right type and we can show you how to replace it and when it should be replaced. Just let us know you need some help with that part.)

We make sure your system is safe. That means you can live comfortably in your home and feel secure your system is in the best working condition for you and your family’s safety.

HVAC system & equipment

But everything runs fine…it heats/cools my house

That 'fine' running system doesn't always look so good on the inside.

My furnace keeps me warm, my air conditioner keeps me cool, why do I need maintenance?

Here's why:

Even if your system is running fine, there is a possibility of a safety issue or efficiency issue that isn’t noticeable from the outside. We can diagnose and locate a lot of problems before they happen, while taking this in depth look into your system. Wouldn’t you like to save yourself costly repairs in the future? Wouldn’t you like the peace of mind you and your family can sleep safely knowing your system is safe?

Other common concerns are:

It's only been one season since my air conditioner or furnace was installed.


My system was just installed last year. I don't need maintenance yet.

You wouldn’t want to drive your car 100,000 miles before an oil change, would you? No! That would be like running your HVAC, air conditioner, furnace, or boiler more than one season. So many things can be prevented with a quick regular maintenance appointment.

Perhaps this is your situation:

I don't need maintenance because I just had a service call on my system for an issue it had.

Or maybe you're wondering,

What is the difference between a service call and a maintenance call?

If you just had a service call, that means something wasn't working right. Service calls happen because you had a problem. You definitely want a maintenance call as soon as possible after a service call, because if one or two things failed... more can, and soon.

During the service call, problems are fixed

  1. The technician takes his time to diagnose the issue,

  2. Find out what caused that particular issue

  3. Look for some things in the immediate vicinity that could cause problems in the future,

  4. Fixing the problem they were called to fix and whatever they see is wrong in the vicinity, not the entire system, or possibly not parts behind or next to the problem area.

During a maintenance call the technician inspects, cleans, tests and fixes problems before they start. Maintenance appointments usually last 1-2 hours unless some problem that needs attention needs more time.

Just a glance at some of the many important items done in a maintenance call are:

  • Combustion testing

  • Air quality and air flow testing

  • Carbon monoxide management tests

  • Air flow management

  • Cleaning and maintenance on crucial components for maximum safety and efficiency

Fixing current problems and future problems. If we see a failed component, or component that is going to fail soon, we will inform you:

  • Which service repair needs done

  • What can happen without the repair and

  • Let you know if you need to schedule a time to fix the issue if a part needs to be ordered, or if we can take care of it at the moment

  • What it will cost for the repair, so you can make an informed decision on the repair needed

My utility Bill keeps going up, more than just the standard increases, it costs so much to run the heat/air.

Tiny inconveniences, bigger problems, & bigger monthly utility bills, that is why a maintenance call is so important.

But I can't afford a maintenance visit!

We want to make sure you’re not overpaying on your utility bills by performing high efficiency maintenance. Boosting your efficiency means lower utilities to run those systems. Saving you money long term.

Red hot room over here

If you can think of a room that has ductwork going to it, that is not as comfortable as the other rooms in your house (too hot or too cold) that means your system is not running as efficiently as it could be. This can cost you extra money in utility bills every month this issue goes unresolved.

Is your furnace or air conditioner (depending on season) running constantly, or for more than 15-20 minutes at a time? That is a sign there is definitely a problem and it should be looked at right away to save you money and to be sure your system is safe.

Some safety issues can be prevented. If the problem is found soon enough before symptoms start, it can keep that and more problems from happening. Get it inspected soon to stay safe.

We don't get rich off of maintenance calls. In fact, they are one of the least profitable things we do. We are trying to keep you safe and save you money. That is why this is so important. We do offer financing for many of the services we offer, you can ask about that when you schedule.
