Central Air Close-up: Suction Line Insulation

Posted on July 22, 2024Rick Welter

It doesn’t take a lot of complicated machinery to generate heat. Rub two sticks together fast enough, and you have a fire that can warm an entire room. Even a home furnace system works on basic principles: Heat source, fan, ducts.

Creating cool air, however, is more complicated. An air conditioning (A/C) system requires a cooling fluid, a condenser, an evaporator, a fan… certainly not something you can accomplish with two sticks and a wilderness manual.

In the Central Air Close-Up series, we’ll look at specific parts of the A/C system—what they are, what they do and how to keep them maintained. For this one, we’re looking at the suction line and suction line insulation. Read more ›

Common HVAC Problems: Draft Induction Fans

Posted on July 15, 2024Rick Welter

Have you heard strange noises coming from the walls at night? Has the temperature inside your home dropped? You may need help from a professional.

No, it’s not time to call the Ghostbusters, even if what’s happening seems a little spooky. It’s just time to check your draft induction fan. These fans may be a small part of your HVAC system, but they have an outsized impact on how well your furnace functions. In fact, if your draft induction fan goes out, your furnace may not even turn on.

Let’s look at what a draft induction fan is, how you can tell if it needs servicing, and what to do next. Read more ›

First-time Home Buyers’ Guide to HVAC

Posted on July 8, 2024Rick Welter

Happy millennial couple of homeowners enjoying cool conditioned air, resting on couch together, using remote control for AC, cooling domestic equipment start.

When you’re looking to buy your first home, you likely have a list of must-haves and want-to-haves. Maybe an en-suite bathroom is a top priority, while a huge kitchen is negotiable.

Your wish list probably doesn’t specify what type of heating and cooling system (HVAC) you would prefer. That’s understandable! It’s easy to assume your new home has a sufficient HVAC system to keep you comfortable in all kinds of weather. 

However, that may not always be the case.

This HVAC guide will help you make sure your starter home is warm in the winter and cool in the summer, without astronomical energy costs. Read more ›

Upgrade for Less: Energy Efficiency Programs for Homeowners

Posted on July 1, 2024Rick Welter

Modern HVAC units are dramatically more efficient than their older counterparts. While a new gas furnace might operate at 95% efficiency, a unit from just 30 years ago might be 80% efficient or less. 

Why does it matter? The more efficient your HVAC is, the less energy it requires to keep your home comfortable. Upgrading your HVAC is an investment that pays dividends over time. 

If you’re still on the fence about an upgrade, the State of Minnesota is making the decision easier with its new energy efficiency programs. 

Here’s what you need to know about the new programs and options for improving your HVAC efficiency today. Read more ›

What Updated Energy Efficiencies Mean for Your HVAC System

It seems like an easy task to measure the efficiency of an HVAC system. You just look at how much energy you put into the unit, versus how much cooling you get out of it, right?

But energy efficiency ratings aren’t that simple. Cooling units aren’t tested in a real-world environment; they’re tested in a lab. The way these tests are conducted can make a difference in efficiency ratings. When new technology makes more accurate testing possible, the ratings can change.

The U.S. Department of Energy (DOE) enacts requirements to standardize efficiency testing, determine what minimum efficiency ratings should be, and make sure the ratings are as accurate as possible.

On January 1, 2023, the DOE put new requirements into place. This new Seasonal Energy Efficiency Rating (SEER) replaces the original standards, so it’s informally called “SEER2.” 

Here’s what you need to know about SEER2 and why it matters. Read more ›
