0 stars if I could. Bought a faulty (not to mention overpriced) surface igniter, called back five minutes later after installing, of course they didn’t stand behind their part. Go to Grainger instead. Same (working) part, half the price.
Response from the owner:Hi there. I am unable to locate your customer profile. Please give our office a call at 314-471-7625 so we can get this figured out for you.

Response from the owner:Thank you for the positive feedback! We're glad to hear that you were pleased with our prompt and friendly service. We look forward to assisting you again in the future!
I will always call Hoffmans for my air and heat needs. They were out to my daughters house that day and fixed it. It was right before the weekend storm with below zero temps the next day. They saved my daughter and grandbabies. I could never thank them more.
Response from the owner:We are so happy to hear that we could help! Thank you for the kind review.
Snow and drifting snow covered intake and out take vents causing the furnace emergency to shut off furnace. Cleaned off the driftibg/ snow off roof and vents furnace works perfect now. Thank you and great job Nick.

Got a quote over the phone. Everything was explained thoroughly. Dakota, my technician arrived and on time, was very professional and knowledgeable. He didn’t try to upsell or change anything. He did a great job. We can already tell the difference since the ducts and vents were cleaned. Would recommend an use Hoffman again in the future.
Response from the owner:Happy to hear you had a pleasant experience using Thomas Hoffmann!

Furnace Inspection and Cleaning
A thorough furnace inspection is at the core of winter HVAC maintenance. A technician will inspect various components to ensure they function properly. This may include:
Burner and Heat Exchanger Inspection: A technician will inspect the burner for signs of dirt or debris that could impede performance. They’ll also examine the heat exchanger, checking for any cracks or corrosion that could lead to issues such as carbon monoxide leaks.
Gas or Oil Connections: Secure connections are essential for gas or oil furnaces’ performance and safety. Technicians inspect these connections for potential leaks or weaknesses that could cause hazards or reduce system efficiency.
Cleaning and Adjusting the Furnace: Dirt and dust can accumulate in your furnace over time, impacting its efficiency. Cleaning and making minor adjustments to settings can help optimize performance and energy usage.
Checking and Replacing Filters
While filters are often associated with summer cooling, they’re just as necessary during the winter. Dirty filters can hinder airflow, making your furnace work harder and increasing energy consumption. During a winter tune-up, a technician will examine the filters and replace them if needed to improve airflow and reduce strain on the system. Regularly scheduled filter replacement also supports better indoor air quality by capturing dust, pollen, and other airborne particles.
Thermostat Evaluation
A functioning thermostat is essential for maintaining the desired temperature in your home. During a winter HVAC check-up, a technician will examine the thermostat to verify that it’s accurately reading the temperature and that all settings are correctly adjusted. This may involve:
Calibration Check: An improperly calibrated thermostat can lead to temperature inconsistencies in your home. Calibration adjustments may be made to support accurate temperature settings.
Programming Assistance: If you have a programmable or smart thermostat, your technician can help adjust settings to optimize energy efficiency during winter. This can include setting lower temperatures at night or when your home is unoccupied.
Inspecting Electrical Connections and Components
Winter can strain your HVAC system, making it important to confirm that all electrical connections and components are secure and in good condition. Loose or corroded connections can reduce system efficiency and pose safety hazards. A technician will tighten connections, test voltage, and inspect key electrical components like capacitors and relays.
Testing Safety Features
Winter HVAC maintenance is also about maintaining a safe environment for St. Louis residents. Most heating systems have safety features designed to shut down the system if specific parameters are exceeded. During a winter check-up, a technician will test these safety features including:
Limit Switch Testing: The limit switch helps prevent your furnace from overheating. By testing this switch, technicians can assess whether it’s functioning as intended to support safe operation.
Carbon Monoxide Testing: A carbon monoxide test is crucial if your heating system is gas or oil-powered. A technician will examine the system for any signs of leaks, which could release harmful gases into your home.
Verifying Proper Airflow
Proper airflow is vital to efficient heating, as it allows warm air to be evenly distributed throughout your home. During winter maintenance, a technician will check for blockages or obstructions limiting airflow. They may inspect:
Ducts and Vents: Ducts and vents can accumulate dust, pet hair, and other debris over time. During a winter inspection, your technician may recommend duct cleaning if they detect significant build-up that could obstruct airflow.
Blower Components: A blower in good condition helps push air through the ducts effectively. Inspecting and adjusting blower components, your technician can help maintain optimal airflow and improve system performance.
Inspecting the Pilot Light or Ignition System
Gas-powered heating systems rely on a pilot light or an electronic ignition system to start heating. A technician will inspect these components to ensure they’re functioning reliably. If the pilot light or ignition system is not working correctly, it can lead to inconsistent heating and higher energy bills.
Providing Recommendations for Additional Services
Finally, a winter HVAC check-up may reveal specific issues or areas of concern that could benefit from additional attention. For example, older systems may perform less efficiently over time, and replacement parts may be recommended to enhance performance. Additionally, if your home experiences drafts or uneven temperatures, a technician may suggest adjustments or upgrades to improve overall heating effectiveness.
