Show your furnace system some TLC
Homeowners should replace their furnace filter every 60 to 90 days. Yet, for many homeowners, replacing the furnace filter is a household chore that falls under the radar. But operating a furnace with a dirty filter can lead to a breakdown.
Furnace filters remove particulates such as dust, pollen, and pet dander. When it becomes, it can your furnace has to work harder and can cause heat exchanger to overheat and fail.
If you’ve properly replaced your furnace filter and are still experiencing furnace problems, like high energy bills, call the heating specialists at Harker. We’ll visit your home and give you a fair estimate to fix it fast.

Is it time to repair or replace your air conditioner?
In Verona, we may only use our air conditioner for three months out of the year, but it’s not exactly something Wisconsinites can live without. Though we’re better known for our freezing winters, our summers also get brutally hot — and everybody needs a place to cool off.
Not sure if your home cooling system is on the fritz? Here are 5 signs your A//C needs repair:
- The unit is blowing hot air
- There are water leaks or excessive moisture
- The unit makes strange, grating sounds

Your source for indoor air quality solutions

The most common signs include:
- A build-up of sediment, such as dirt and sand

- Too much internal pressure, or a broken T&P valve

Common HVAC Problems Verona Homeowners Face
Living in Wisconsin means dealing with temperature extremes, and that takes a toll on your HVAC system. Here are some of the most common issues we address for Verona residents:
Furnace Breakdowns in Winter — The furnace fails precisely when you can’t afford to wait. We diagnose the problem quickly and get you back to a comfortable temperature.
Poor Heating or Cooling Performance — Your system runs, but it’s not keeping your home at the right temperature. This could be a refrigerant leak, a clogged filter, or a worn-out component.
High Energy Bills — If your heating or cooling costs spike unexpectedly, an aging or inefficient system might be the culprit. We can assess your current setup and discuss energy-efficient alternatives.
Strange Noises or Odors — Grinding sounds, rattling, or burning smells from your HVAC system are red flags. These warrant a professional inspection right away.
Uneven Temperatures — One room is cold while another is warm. This could point to ductwork issues, thermostat problems, or system imbalances that we can diagnose and fix.
Frequent Repairs — If you’re calling for repairs several times a year, your system might be approaching the end of its lifespan. We’ll help you weigh repair versus replacement options.
How to Know It's Time to Upgrade Your System
Wondering whether to repair or replace your heating and cooling system? Here are some signals that an upgrade might make sense:
Age Over 15 Years — Most HVAC systems last 15-20 years. If yours is approaching or past this mark, replacement might be more cost-effective than ongoing repairs.
Rising Repair Costs — When repairs add up to significant expense, a new system often makes financial sense, especially if energy efficiency ratings have improved.
Energy Bills Climbing — Newer, high-efficiency systems use significantly less energy. Over time, the savings on your utility bills can offset the installation cost.
Inconsistent Comfort — If you can’t maintain even temperatures throughout your home, a new system designed for your home’s layout might solve the problem.
We’re happy to provide a free, no-obligation assessment. We’ll explain your options—repair versus replacement—and let you decide what works best for your budget and comfort needs.
Why Professional Installation and Maintenance Matter
You might be tempted to DIY or hire the cheapest contractor, but when it comes to HVAC systems, professional expertise pays off. Poor installation can void warranties, reduce efficiency, and create safety issues. Regular maintenance keeps your system running efficiently and helps catch problems before they become emergencies.
We follow manufacturer specifications for every installation and include comprehensive maintenance plans with new equipment. Our technicians are trained on the latest systems and best practices, so you get reliable service that lasts.
Financing Options and Special Offers
We understand that replacing or upgrading your HVAC system is a significant investment. That’s why we offer flexible financing options to fit your budget. We also provide seasonal specials on maintenance and inspections, so you can save money while keeping your system in top shape.
Ask about our energy-efficient equipment options and federal tax credits you might qualify for. Upgrading to a high-efficiency system could lower your energy costs and make your home more comfortable.
