The number one cause of preventable HVAC failures is skipped maintenance. A $150 annual tune-up catches the capacitor that's about to fail before it takes out the compressor. It catches the dirty coil that's been adding 20% to your electric bill. It catches the cracked heat exchanger before it produces CO. LC Heating & Air's maintenance visits are thorough, documented, and honest — we don't generate fake repair recommendations.

I'm Leo, owner of LC Heating & Air. I've spent years working on the diverse housing stock here in Arlington Heights, from older single-family homes to updated duplexes. One thing I've learned is that our local climate—with its intense heat and occasional air quality issues—is tough on HVAC equipment. If you aren't keeping up with annual maintenance, you're likely paying more in energy bills than you need to, and you're risking a breakdown on the hottest day of the year.
My approach to maintenance is simple: I treat your home like my own. I don't believe in high-pressure sales or inventing problems. I believe in showing up, doing a thorough 21-point inspection, and giving you an honest assessment of your system's health. If your unit is running well, I'll tell you. If I find a part that's wearing out, I'll show you why it matters and what your options are. We're here to help you make informed decisions, not to push equipment you don't need.

Common HVAC Issues in Arlington Heights
In Arlington Heights, we deal with a mix of older electrical systems and varying duct conditions. A common pattern I see is airflow restriction caused by years of dust accumulation or poorly sealed ductwork in older remodels. When airflow is restricted, your blower motor works harder, your coils get dirtier faster, and your system loses efficiency. We often find that a simple cleaning and a check of the blower motor can restore performance that homeowners thought was lost to 'old age.'
Another issue is the 'hidden' failure. Because we have such long cooling seasons, capacitors and contactors—the small electrical parts that start your motor—get a real workout. These parts don't usually fail all at once; they degrade. During a maintenance visit, I check the microfarad rating on your capacitor. If it's drifting, I'll recommend a replacement. It's a small, inexpensive fix that prevents the motor from overheating and failing entirely, which is a much more expensive repair.
Understanding Your Home's HVAC Needs
Arlington Heights has a unique mix of architecture. Whether you're in a classic single-family home or a small multifamily building, the way your HVAC system is installed matters. Many older homes were retrofitted with central air, sometimes in tight attic spaces or cramped closets. This makes service access a critical factor. If a system is installed in a way that prevents proper cleaning of the coils or inspection of the drain line, you're going to have problems.
I always look at the 'big picture' of your system. It's not just about the furnace or the condenser; it's about how the whole system breathes. If your ducts are leaking or your return air is undersized, no amount of maintenance will make the system run perfectly. I'll point these things out during my visit so you can decide if a small repair or a larger duct improvement is worth the investment for your specific property.
Our 21-Point Inspection Process
When I come out for a maintenance visit, I follow a strict 21-point protocol. I don't just change a filter and leave. I check the electrical connections, measure the amp draw on motors, test the capacitor, inspect the contactor for pitting, and clean the coils. For your heating system, I perform a combustion analysis and check for carbon monoxide leaks. Safety is the priority.
Everything is documented. I provide a written report of what I found. If I see a part that is nearing the end of its life, I'll explain the risk. You get to decide if you want to replace it now, wait, or monitor it. My job is to provide the information; your job is to decide what fits your budget and your plans for the home.
Repair or Replace? An Honest Assessment
This is the question I get asked most often. There is no 'one size fits all' answer. If your system is 10 years old and needs a $300 repair, it's almost always worth fixing. If it's 20 years old, uses an obsolete refrigerant, and needs a major compressor repair, that's a different story. I'll give you the math so you can see if you're throwing good money after bad.
I don't recommend replacing a system just because it's 'old.' If it's running efficiently and keeping you comfortable, keep it running. I'll help you squeeze every year of life out of your equipment through proper maintenance. But when the repair costs start to approach the value of the unit, or when the system is no longer safe to operate, I'll be the first to tell you it's time to look at a replacement.
Understanding Costs and Value
I believe in transparent pricing. You'll know what the maintenance visit costs before I start. For repairs, I provide a written estimate. I don't have hidden fees, and I don't use 'trip charges' to get in the door and then hit you with a massive bill. My goal is to build a relationship with my neighbors in Arlington Heights, and that only happens if I'm fair.
Regarding rebates and incentives, I always recommend checking with your local utility provider for current programs. While I don't control those, I can help ensure your new equipment meets the necessary efficiency ratings to qualify for them if you do decide to replace your system.
Scheduling and Access
I know your time is valuable. When we schedule a visit, I make sure we have enough time to do the job right. I don't rush through inspections. I also need to make sure I have access to the equipment. If your unit is in an attic or a tight crawlspace, let me know when you book. I'll bring the right tools and safety gear to get the job done without damaging your home.
If you're on our annual maintenance plan, you get priority scheduling. This is a big help during the first heat wave of the year when everyone is calling at once. We'll reach out to you to get your Spring AC tune-up and Fall heating check on the calendar so you don't have to worry about it.
Health and Safety First
Your HVAC system is a major part of your home's health. A gas furnace that isn't burning correctly can be a carbon monoxide hazard. A dirty evaporator coil can become a breeding ground for mold if the drain line isn't flushing properly. During every maintenance visit, I check the safety controls and the combustion process. It's not just about keeping you cool; it's about keeping you safe.
If I find a safety issue, I won't leave until we've discussed the risks and the immediate steps needed to secure your home. I take this part of my job very seriously. You deserve to sleep soundly knowing your heating and cooling systems aren't putting your family at risk.

When it comes to HVAC, the best decision is an informed one. If your system is acting up, start by checking the basics: is the filter clean? Is the thermostat set correctly? If those aren't the issue, give us a call. We'll come out, perform a diagnostic, and give you a clear, written estimate for any repairs.
If the repair is minor, we'll fix it. If the system is failing, we'll explain why and give you the information you need to decide on a replacement. We don't push for new equipment unless it's truly the most practical, long-term solution for your home.
