When DIY Might Be An Option
Some minor HVAC repair issues can be solved on your own. Explore these scenarios where DIY may be your family’s quickest and cheapest option.
- Troubleshooting a furnace fan that keeps shutting off: Check your thermostat and air filter. You may need to simply replace these HVAC parts or replace the batteries on your smart thermostat.
- Identifying and tightening loose connections: Inspect electrical connections and wiring within your HVAC unit for any signs of looseness or damage. Call an HVAC repair professional for help when you notice the electrical connections need tightening or repair. Your regular inspection can save money on emergency HVAC repair.
- Upgrading a thermostat: Are you noticing a temperature difference from what you set on the thermostat to what your HVAC system is blowing? Replacing an old thermostat with a new, programmable model can improve HVAC reliability, efficiency, and comfort. Order this HVAC part at your local hardware store or search online for your desired model. Follow all instructions provided in the box for installation.
- Installing a new air filter: Musty or dusty air filters can be improved with an air filter replacement. Regularly replacing your air filters (every 90-120 days) is essential for maintaining good air quality and system efficiency. Order a furnace or AC filter at your local hardware store or online and follow our image guide below for replacement help.


If you’re able to perform these HVAC DIY steps, you will improve how your heating and cooling system functions. All furnace parts and HVAC equipment can be purchased at your local hardware store or online. If any of these issues are recurring, even after an air filter replacement or thermostat upgrade, contact an HVAC company for help.
When to Hire HVAC Repair Professionals
You should contact a professional HVAC company for anything outside of basic heating and cooling maintenance. Here are scenarios where calling a trained technician for HVAC repair will be your best option.
- Solving a refrigerant leak in HVAC coils and refrigerant lines: Refrigerant is a hazardous chemical that can cause serious health problems if mishandled. Call experts at your local HVAC repair company to take care of this specialized task.
- Correcting electrical problems: If you’re unfamiliar with your home’s electrical wiring and your HVAC system, contact the pros at HVAC Comfort Inc. In all of our HVAC inspections, we test the electrical connections and resolve problems that may be impacting your home’s heat and air conditioning. It’s not uncommon to have electrical issues rooting from a tripped breaker, a blown fuse, or even a faulty thermostat.
- Resolving a gas leak and ensuring long-term safety: Gas leaks from a cracked heat exchanger, loose connection, or damaged lines are extremely dangerous and should only be handled by licensed professionals. If you smell or are alerted about a gas leak, leave the home immediately and call your gas provider.
- Inspecting and fixing ductwork problems: If you notice holes in your ductwork, loose connections, or air blockages, contact an HVAC company to order and replace the parts. Leaky or damaged ductwork can significantly reduce your HVAC system’s efficiency and lead to higher energy bills.
- When a furnace or AC part needs to be replaced: Replacing an air filter or installing a new thermostat is a simple DIY task. Trying your skills at another furnace and AC part may be tempting, but doing this yourself leaves room for potential problems. The team at HVAC Comfort Inc brings specialized tools and expertise to all HVAC part replacement service calls.
