What Happens During a Professional HVAC Inspection?

March 17, 2026

Your HVAC system works year-round to keep your home comfortable, but most homeowners don’t think about it until something stops working. Heating and cooling systems are complex, and without routine maintenance, small issues can quickly turn into costly repairs. A professional HVAC inspection helps prevent breakdowns, improve efficiency, and extend the life of your system. 


At Custom Cooling & Heating, an HVAC inspection is a detailed process designed to ensure your system is operating safely and reliably before peak seasons arrive. 



It Begins with the Thermostat and System Controls 

Every inspection starts with evaluating the thermostat. Since it controls when your system turns on and off, it must accurately read your home’s temperature and communicate properly with the HVAC equipment. If it’s not calibrating or cycling correctly, you may notice uneven temperatures or higher energy bills. 


The technician will also confirm that the system starts, runs, and shuts off as it should. This initial check ensures the core controls are functioning before diving deeper into mechanical components. 



Electrical Components Are Carefully Examined 

Electrical problems are a leading cause of HVAC system failures. Over time, normal vibration and wear can loosen connections or weaken parts. During an inspection, the technician checks wiring, tests key electrical components, and measures voltage levels to ensure everything is operating within safe limits. 


Catching small electrical issues early can prevent sudden outages, especially during extreme weather when your system is working hard. 



Airflow and Efficiency Are Evaluated 

Proper airflow is essential for both comfort and energy efficiency. A clogged air filter or restricted airflow can force your system to work harder, increasing wear and tear. During a professional HVAC inspection, the technician checks the air filter and evaluates overall airflow throughout the system. 


If airflow is restricted, it can lead to uneven temperatures and higher energy costs. Addressing these concerns early helps your system run more smoothly and efficiently. 



Heating System Inspection 

If your home uses a furnace, the heating components are inspected for both performance and safety. The technician examines the ignition system, burners, and safety controls to ensure everything is functioning properly. The heat exchanger is also checked, as any cracks or damage could pose safety concerns. 


Heating systems often run continuously during colder months, so ensuring safe and efficient operation before winter arrives can prevent emergency service calls.



Cooling System Inspection 

For air conditioning systems, the focus shifts to cooling performance. The technician checks refrigerant levels, inspects coils, and evaluates the outdoor condenser unit. Low refrigerant or dirty coils can significantly reduce efficiency and make it harder to keep your home cool. 


The condensate drain line is also inspected to ensure moisture is draining properly. A clogged drain can cause water damage or system shutdowns if not addressed. 



Moving Parts and Overall Performance 

HVAC systems contain motors, fans, and other moving parts that naturally experience wear over time. During the inspection, these components are examined for signs of strain or deterioration. In some systems, moving parts may require lubrication to reduce friction and extend their lifespan. 


Once all components are inspected, the system is run through a performance test. This allows the technician to confirm proper temperature output, consistent cycling, and overall efficiency. If adjustments are needed, they can often be made during the same visit. 



Why Routine HVAC Inspections Matter 

Many homeowners wait until they notice a problem before scheduling service. Unfortunately, by the time a system shows obvious signs of trouble, repairs may already be necessary. Routine HVAC inspections allow small issues to be addressed before they turn into major problems. 


Regular inspections can improve energy efficiency, lower utility bills, and extend the life of your equipment. Most systems benefit from service at least once a year, and many homeowners choose inspections before both heating and cooling seasons to ensure peak performance. 


Preventative maintenance not only protects your investment but also provides peace of mind knowing your system is ready for whatever weather comes next.

How to Choose the Right HVAC Filter for Your Home

February 17, 2026
Your HVAC filter might seem like a small part of your heating and cooling system, but it plays a huge role in your comfort, air quality, and system efficiency. The right filter helps keep dust, allergens, and debris out of your home while protecting your HVAC equipment from unnecessary wear and tear. Choosing the wrong one, however, can restrict airflow, reduce efficiency, and even shorten the life of your system. At Custom Cooling & Heating , we help homeowners make smart choices that improve indoor comfort and protect their investment. With convenient online ordering for HVAC filters and the option to save 10% through auto delivery, maintaining your system has never been easier. Here’s how to choose the right HVAC filter for your home. 1. Understand Your Filter Size Before anything else, you need the correct size. HVAC filters come in many dimensions, and using the wrong size can allow unfiltered air to bypass the system. Your filter size is typically printed on the side of your current filter. It will look something like: 16 x 25 x 1 or 20 x 20 x 4 This represents length, width, and thickness in inches. If you’re unsure, Custom Cooling & Heating can help you identify the correct size, so you can order with confidence. 2. Learn About MERV Ratings MERV stands for Minimum Efficiency Reporting Value . This rating tells you how well a filter captures particles. The higher the MERV rating, the more particles it traps. Here’s a simple breakdown: MERV 1–4: Basic protection, captures large dust particles. MERV 5–8: Good for most homes, captures pollen, mold spores, and dust mites. MERV 9–12: Ideal for allergy sufferers, pets, and improved air quality. MERV 13+: Hospital-grade filtration, may restrict airflow if your system isn’t designed for it. For most residential systems, a MERV 8–11 filter is the sweet spot. It provides excellent air filtration without putting extra strain on your HVAC system. 3. Consider Your Home’s Needs Your household environment should guide your filter choice: Pets in the home: Choose a higher MERV rating to trap pet dander and hair. Allergies or asthma: Look for filters designed to capture allergens like pollen, mold, and dust mites. New construction or remodeling: Higher filtration helps capture fine dust particles. Smokers in the home: A stronger filter can help remove smoke particles and odors. The right filter doesn’t just protect your system, but it improves the air you breathe every day. 4. Balance Filtration and Airflow It’s tempting to go with the highest MERV rating available, but more isn’t always better. Filters that are too dense can restrict airflow, making your HVAC system work harder. This can lead to: Reduced efficiency Higher energy bills Increased wear on your equipment Potential system damage Custom Cooling & Heating recommends selecting a filter that matches your system’s capabilities while still meeting your air quality goals. 5. Choose the Right Filter Type There are several common types of HVAC filters: Fiberglass Filters: Inexpensive, basic protection, lower efficiency. Pleated Filters: Most popular option, better filtration, longer lifespan. Electrostatic Filters: Use static electricity to trap particles, washable or disposable. High-Efficiency Filters: Ideal for allergy control and improved air quality. Pleated filters are usually the best choice for most homes because they balance performance, cost, and airflow. 6. Replace Your Filter Regularly No matter how good your filter is, it won’t work if it’s clogged. A dirty filter reduces airflow, increases energy usage, and allows dust to build up in your system. General replacement guidelines: Every 1–2 months: Homes with pets or allergies Every 2–3 months: Standard households Every 3–6 months: Thicker, high-capacity filters Keeping up with filter changes is one of the easiest ways to extend the life of your HVAC system and maintain indoor comfort. 7. Take Advantage of Online Filter Ordering Custom Cooling & Heating makes it simple to get the right filters delivered right to your door.

Why Your Furnace Runs Constantly (And What That Means for Your Home)

January 5, 2026
If it feels like your furnace never shuts off, you’re not imagining things and you’re not alone. One of the most common concerns we hear from homeowners is why their furnace runs constantly, especially during colder months in Nebraska. While some run time is normal in winter, a furnace that seems to run nonstop can be a sign of underlying issues that affect comfort, efficiency, and energy costs. At Custom Cooling & Heating , we help homeowners understand what their heating system is telling them and when it’s time to take action. Here’s what it means if your furnace is running constantly and what you should do about it. Is It Normal for a Furnace to Run All the Time? During periods of extreme cold, your furnace may run longer cycles to keep your home at the set temperature. This can be completely normal, especially if outdoor temperatures are well below freezing. However, if your furnace rarely shuts off or struggles to reach the desired temperature, there may be an issue affecting performance or efficiency. Understanding why your furnace runs constantly starts with identifying the most common causes. Common Reasons Your Furnace Runs Constantly 1. Dirty or Clogged Air Filter A dirty air filter is one of the most common and easily fixable reasons a furnace runs nonstop. When the filter is clogged, airflow is restricted, forcing the furnace to work harder and longer to circulate warm air throughout your home. What this means for your home: Reduced airflow can lead to uneven heating, higher energy bills, and unnecessary wear on your furnace. Regularly changing your air filter helps your system run more efficiently and maintain proper airflow. You can buy your air filters online and save 10% on auto ship. 2. Thermostat Issues or Incorrect Settings Sometimes the problem isn’t the furnace itself, it’s the thermostat. Incorrect settings, calibration issues, or an aging thermostat can cause your system to run continuously. What this means for your home: If your thermostat isn’t accurately reading the indoor temperature, your furnace may think it needs to keep running even when your home is already warm. A properly functioning thermostat helps regulate heating cycles and prevents unnecessary run time. 3. Poor Insulation or Air Leaks If warm air is escaping your home through poor insulation or drafts, your furnace will continue running in an attempt to maintain the desired temperature. What this means for your home: Heat loss forces your system to work harder, increasing energy usage, and reducing comfort. Sealing air leaks and improving insulation can significantly reduce furnace run time and improve efficiency. 4. Mechanical or Maintenance Issues Worn components, improper airflow, or lack of regular maintenance can also cause excessive run time. Small issues can add up, reducing efficiency and shortening the lifespan of your furnace. What this means for your home: Ignoring these issues can lead to more serious repairs down the road. Routine maintenance helps identify and correct problems before they impact system performance. What Constant Furnace Run Time Means for Energy Costs When homeowners ask why their furnace runs constantly, energy efficiency is often the biggest concern. A furnace that runs longer than necessary uses more energy, which can lead to noticeably higher heating bills. Addressing airflow issues, maintenance needs, and insulation concerns can help your system operate more efficiently, saving money while improving comfort. When Should You Call a Professional? If your furnace is running constantly and you’ve already checked the air filter and thermostat settings, it’s a good idea to have a professional take a closer look. Ongoing run time can signal issues that aren’t visible to the average homeowner. A professional inspection can help determine whether your furnace needs adjustment, repair , or routine maintenance to restore proper operation. How Custom Cooling & Heating Can Help At Custom Cooling & Heating, we help homeowners diagnose heating issues, improve efficiency, and stay comfortable throughout the winter. Whether it’s routine maintenance, system repairs, or evaluating overall performance, our goal is to help your furnace work the way it should efficiently and reliably. We focus on practical solutions that extend the life of your system and help prevent costly breakdowns during the coldest months of the year. Take Control of Your Home’s Comfort If you’re wondering why your furnace runs constantly, don’t ignore the signs. Addressing the issue early can improve comfort, lower energy costs, and protect your heating system. Contact Custom Cooling & Heating today to schedule an inspection or maintenance service and ensure your furnace is running efficiently all winter long.
