If your utility bill keeps climbing and your home doesn’t feel any more comfortable, your HVAC system might be to blame. Heating and cooling typically account for the largest portion of a home’s energy use, and even small inefficiencies can lead to major cost increases over time.
At A&R Mechanical, we help homeowners in Amarillo diagnose the root causes of high energy bills and resolve common HVAC problems before they become expensive. If you’re wondering why your heating or cooling costs are rising, here are the top issues to look out for.
1. Dirty or Frozen Air Conditioner Coils
One of the most common problems we see during Amarillo’s hot summers is air conditioner coils freezing up. When coils freeze, your system has to work harder to maintain the desired temperature. This decreases efficiency while increasing energy use and wear on your equipment.
Frozen coils are often caused by restricted airflow due to dirty filters, blocked return vents, or low refrigerant levels.
What you can do:
Replace your air filter regularly, keep vents clear, and schedule routine maintenance to catch low refrigerant or internal system issues early.
2. Poor Insulation or Air Leaks
Your HVAC system can be in perfect shape, but if your home isn’t properly insulated, you’ll still pay more to heat or cool it. Drafts around windows and doors, unsealed ductwork, and poor attic insulation allow conditioned air to escape and outside air to enter. This forces your system to run longer and harder.
Simple fixes include:
Weather stripping doors and windows, sealing visible duct gaps, and adding insulation in attics or crawl spaces.
3. Thermostat Malfunctions
When a thermostat is poorly calibrated, outdated, or malfunctioning, it can cause your system to cycle too often or run longer than needed. Inconsistent temperatures and increased energy use are both common signs of a thermostat problem.
A programmable or smart thermostat can help you regain control of your energy use by creating schedules and adjusting temperatures when you’re away. For households with gas heating, it’s also essential to pair your heating system with a carbon monoxide detector to protect against undetected fuel-burning hazards.
4. Lack of Routine Maintenance
Skipping seasonal tune-ups is one of the top contributors to reduced HVAC efficiency. Over time, dust, debris, and worn components cause your system to work harder than necessary.
Professional heating repair in Amarillo should include cleaning internal parts, checking refrigerant levels, inspecting ductwork, and verifying that all components are operating efficiently.
Regular maintenance improves performance, extends equipment life, and keeps your energy bills predictable.
5. Air Conditioning Not Working Properly
If your air conditioning is not working as expected, even if it’s still running, you may be wasting more energy than you realize. Weak airflow, warm air, and frequent short cycling can all signal internal inefficiencies that make your system consume more power.
In Amarillo’s summer heat, these issues get worse quickly and can lead to major system failure if not addressed.
Solution:
Call for a full system inspection to determine if your system is low on refrigerant, has airflow obstructions, or is experiencing electrical faults.
6. Outdated or Oversized Systems
Older HVAC units often lack modern energy-saving features and tend to lose efficiency over time. Oversized systems may heat or cool your home too quickly, which can lead to uneven temperatures and short cycling, both patterns that drive up energy use.
If your system is over 10–15 years old, it may be time to schedule an inspection to see if you need an HVAC replacement.
How to Save Energy on Air Conditioning in Summer and Heating in Winter
Reducing your energy bill starts with small habits and preventive care. If you’re looking for how to save energy on air conditioning in summer, try:
- Setting your thermostat to 78°F when you’re home
- Using ceiling fans to circulate cool air
- Closing blinds during peak sun hours
- Scheduling a preseason HVAC tune-up
For heating in the winter, energy-saving tips include:
- Setting the thermostat to 68°F during the day and lowering it at night or when you’re away
- Sealing drafts around windows and doors
- Replacing furnace filters every 1–3 months
- Using a programmable thermostat to regulate temperature
- Scheduling fall maintenance to ensure your heating system is clean, calibrated, and efficient
These simple steps can make a significant difference in both comfort and cost throughout Amarillo’s hot summers and cold winters.
