Frequently Asked Questions (FAQs)

What is a SEER Rating, and why does it matter?

SEER stands for Seasonal Energy Efficiency Ratio. It measures how efficiently your air conditioning system operates. A higher SEER means better energy efficiency and lower operating costs. Modern systems range from 13 to 21 SEER, with higher numbers offering greater energy savings over time.


Why is the SEER rating on the yellow Energy Guide different from what my HVAC contractor mentioned?

SEER ratings are based on the complete system setup. The rating can vary depending on the indoor and outdoor units combined. For example, your air conditioner may have one SEER value when paired with a specific air handler or furnace and a different rating when combined with another.


Why is routine HVAC maintenance important?

Your heating and cooling systems run hard year-round. Regular maintenance helps prevent breakdowns, maximizes system life, improves efficiency, and catches small issues before they become costly repairs. Preventive care protects your comfort and your investment.


How often should I schedule HVAC maintenance?

For best performance, schedule professional tune-ups twice a year: once in the spring for your cooling system and again in the fall for heating. Boilers, furnaces, heat pumps, and duct systems should also be inspected for wear, leaks, and performance issues.


What HVAC equipment requires preventive maintenance?

All heating and cooling systems—including air conditioners, furnaces, heat pumps, and boilers—need regular upkeep. This includes checks on fans, compressors, coils, ductwork, blowers, filters, and electrical components to ensure optimal operation.


Need help troubleshooting your system?

What are the benefits of a programmable thermostat?

Programmable thermostats let you schedule temperature changes automatically, helping you save energy and stay comfortable without constantly adjusting settings. They’re more accurate than older mercury models and can reduce your monthly energy bills.


What kind of filter should I use? How often should I replace it?

Basic filters protect your system, but media filters and HEPA options improve indoor air quality. Disposable filters should be replaced monthly. If you use a washable filter, clean it once a month to maintain airflow and performance.


Why can’t I find the right filter size for my system at the hardware store?

Trane and other premium systems often use higher-quality, manufacturer-specific filters that aren’t sold in retail stores. Contact Comfort Mechanical to order the correct filter or check if your unit has a washable, reusable filter.


Where can I buy parts for my HVAC system?

Comfort Mechanical can source all the parts you need for your Trane or other HVAC equipment. We ensure you receive the right parts, with proper fit and warranty backing.


What HVAC system is best for my home?

Several factors determine the right system—home size, insulation, duct layout, and even your local climate. Our team performs an in-home assessment to recommend the ideal unit size and setup for year-round comfort and efficiency.


What does my HVAC warranty include?

Most standard warranties cover parts that fail due to manufacturer defects. Labor is not usually included unless you have a protection plan. Comfort Mechanical registers all installed systems for full warranty benefits, and we offer extended warranties for extra peace of mind.


What’s the average lifespan of a heating or cooling system?

Most central air systems last between 10 to 15 years. With regular maintenance, some systems can exceed this range. Factors like usage, climate, and maintenance frequency will impact overall lifespan.


When should I replace my air conditioner or heater?

If your system needs frequent repairs, struggles to keep your home comfortable, or has become inefficient, it may be time for a replacement. Today’s models are much more energy-efficient, offering long-term savings.


Does my HVAC system affect indoor air quality?

Yes! Your HVAC system can circulate allergens, dust, and pollutants. Comfort Mechanical offers solutions like air purifiers, humidifiers, dehumidifiers, and advanced filtration systems to improve indoor air quality.


Do you offer free estimates?

Absolutely! We provide free estimates for new installations and system replacements—whether it’s an air conditioner, furnace, heat pump, or entire HVAC setup.


Can I sign up for a maintenance agreement?

Yes, we offer preventive maintenance plans to keep your HVAC system running smoothly year-round. These plans include seasonal checkups, priority service, and exclusive discounts.


How often should I replace my HVAC filter?

We recommend checking your filter monthly and replacing or cleaning it as needed. Dirty filters reduce system efficiency, raise energy bills, and can lead to system damage over time.

Yes, Comfort Mechanical provides flexible financing options for HVAC replacements and upgrades. Contact us to learn more about how we can help you stay comfortable without breaking your budget.


Is HVAC noise something I should worry about?

Modern HVAC systems are much quieter than older models. However, if your system is unusually loud, it may be due to age, poor insulation, or worn parts. We can help you find a quiet, efficient unit that won’t disturb your peace.
