We were reading up on some common HVAC mistakes homeowners make, and it reminded us just how unique our homes here in New Mexico really are. From sunbaked stucco exteriors and dusty summer winds to aging ductwork and high-altitude quirks, local homes need local solutions. At B. Carlson Heating, Air Conditioning & Plumbing, we’ve been keeping families and businesses comfortable since 1971—and we’ve seen these HVAC pitfalls firsthand.
Here’s our take on the most common heating and cooling mistakes we see across Albuquerque and beyond—plus what to do instead if you want to save money, protect your equipment, and stay more comfortable year-round.
1. Skipping Thermostat Upgrades That Could Save You Hundreds
Whether you’re in an older home that’s never had a programmable thermostat, or you’re ready to make the leap to a smart system, your thermostat plays a huge role in how efficiently your HVAC system runs.
Programmable thermostats are still a powerful tool—especially for New Mexico homes with consistent daily temperature swings and high sun exposure. They allow you to set schedules and reduce energy waste when you’re out of the house. But smart thermostats take things further, learning your habits, optimizing usage in real time, and letting you control comfort from your phone.
For many homes, the ideal setup combines the reliability of programming with the intelligence of smart tech. We help homeowners figure out what will work best for their system—and install it properly so it doesn’t compromise your heating or cooling.
2. Delaying Repairs Can Turn Small Issues Into Expensive Problems
It’s tempting to put off an AC repair when your system is “still running,” but waiting too long often leads to more damage, more expensive parts, and more downtime. This is especially true right now, as supply chain delays and refrigerant transitions are driving up prices.
Whether it’s a weird noise or a room that’s suddenly too warm, early signs usually mean something’s off—and catching it sooner can save you hundreds. Members of our Care Club also benefit from priority scheduling and discounts on repairs, making fast action more affordable.
3. Underestimating Indoor Air Quality in a Desert Climate
A clogged air filter restricts airflow and drives up energy bills—but that’s just the beginning. In our high-desert climate, with its mix of wildfire smoke, spring allergens, and ever-present dust, air filters alone often can’t keep up.
Advanced indoor air quality systems, like whole-home purifiers, HEPA filtration, and UV light technology, go far beyond just trapping particles. They can actively neutralize bacteria, allergens, and odors—making a noticeable difference in how your home feels and smells, especially for sensitive lungs.
4. Ignoring Air Loss and Insulation Shortfalls
Even the most efficient HVAC system can struggle to keep your home comfortable if that conditioned air is slipping through the cracks. Around Albuquerque, it’s not uncommon to find older homes—or homes that have undergone cooling upgrades—that weren’t fully updated to match.
Issues like leaky ductwork, aging insulation, or gaps around windows and doors can cause your system to run longer and work harder, driving up energy bills and wearing out components faster. That’s why it’s so important to make sure your home’s thermal envelope is in good shape.
If you’ve made upgrades but still notice hot and cold spots or rising utility costs, it could be time to assess where air might be escaping and take steps to tighten things up. The payoff in comfort and efficiency is well worth it.
5. Neglecting the Outdoor Unit—Even Though It’s Doing All the Work
Your outdoor condenser unit takes the brunt of our climate—blazing sun, dust storms, blowing debris, and yes, the occasional tumbleweed. When that unit gets clogged with grass clippings or caked with dirt, it can’t release heat efficiently. That strains your system and shortens its lifespan.
A simple rinse and a visual check a few times a year can help, but full cleanings and inspections are part of our Care Club membership, so you don’t even have to think about it.
6. Living With a System That’s the Wrong Size for Your Home
System sizing isn’t just about square footage. Elevation, sun exposure, ceiling height, and insulation quality all play a role. Older homes may have been retrofitted with equipment that was never quite right. Newer builds—especially fast-turn developments—sometimes get undersized units that can’t keep up with real-world conditions, especially upstairs.
In many cases, homeowners think they need a bigger unit, but the smarter solution might be better zoning, improved airflow, or adding a ductless system in specific rooms. We help you make upgrades that actually solve the comfort issues—without overspending on equipment you don’t need.
7. Skipping Routine Maintenance That Protects Your System
Yearly maintenance isn’t a nice-to-have—it’s essential. Dirty coils, low refrigerant, or worn parts can reduce efficiency, strain your system, and even void your warranty.
Our Care Club takes the guesswork out of it. With seasonal tune-ups, thorough inspections, and member-only perks, you can rest easy knowing your HVAC system is being professionally cared for at all times. It’s the smartest way to protect your investment and keep those utility bills down.
8. Upgrading to Refrigerated Air? Don’t Cut Corners
Swamp cooler conversions are one of the most popular upgrades in the region, but doing it right is critical. We’ve seen too many homeowners skip important steps—like duct sealing, insulation upgrades, or electrical panel updates—only to end up with a less efficient system that still doesn’t cool the house evenly.
Done correctly, switching to refrigerated air means more comfort, better indoor air quality, and higher home value. We take care of the entire process so your system works from day one—and we’ve written extensively about what to expect during and after the switch.
9. Missing Out on the Cooling Power of Targeted Ductless Systems
Trying to cool your entire home just to make one room livable isn’t just wasteful—it’s expensive. If you’ve got a home office that bakes in the afternoon sun or a second story that never quite cools down, a ductless mini-split can solve the problem without needing a full system replacement.
This kind of strategic upgrade is especially valuable in homes where space is limited or the main system can’t support an addition. Ductless systems are quiet, efficient, and far more affordable than installing a second central AC—especially when installed by a pro who knows how to integrate them with your existing HVAC setup.
