Yes. An annual cleaning and tune-up is recommended on systems that are one year and older. An annual cleaning and tune-up will ensure that the equipment runs as efficiently as possible…keeping gas and electric costs as low as possible.


In addition, annual maintenance is required by the manufacturer and labor companies to keep the warranties in place. This is to ensure that parts aren’t failing due to neglect.

The temperature difference between upstairs and downstairs can be due to a lack of zoning in the HVAC system, where the entire house is treated as a single unit. An undersized HVAC system for the square footage of your home could struggle to distribute air evenly. Zoning allows for separate temperature control in different areas, addressing uneven heating or cooling.


An appropriately sized system ensures adequate airflow to maintain consistent comfort throughout your living spaces. Consulting with an HVAC professional can help identify the specific issue and implement effective solutions tailored to your home’s unique needs.

The air inside is too dry! Humidity can be added to the air with a whole-house humidifier. Whole-house humidifiers distribute humidity evenly throughout the house using the ductwork. This moisture can help alleviate “shocks,” dry skin and dry wood (flooring and furniture).


A whole-house humidifier requires only annual maintenance and pad change. You can say goodbye to daily water changes as needed in portable humidifiers!

To qualify for tax credits and rebates, efficiency standards play a key role. Furnaces must typically boast an efficiency level of at least 95%, ensuring optimal energy performance. For air conditioners and heat pumps, a minimum 16 SEER (Seasonal Energy Efficiency Ratio) rating is often required, reflecting their effectiveness in cooling.


Additionally, smart thermostats eligible for credits generally need to be WiFi-compatible, enhancing their energy-saving capabilities. These criteria ensure that systems meet stringent efficiency benchmarks, promoting sustainability and rewarding consumers for investing in eco-friendly and technologically advanced HVAC solutions.

Yes! Licensed contractors tend to be a more reliable and reputable choice as compared to those that are not licensed. The work of a licensed contractor is held accountable by the City of Indianapolis through permits and inspections.


The best way to protect your home, valuables and risk of liability while having contractors in your home is to hire a company that is fully insured and bonded. In addition, if work is completed in your home by an unlicensed contractor and a permit not pulled, the City of Indianapolis (and some townships) can place a Stop Work Order and fines on your job.

There is not one brand of equipment that is better than another. All of the major brands are reputable and have a similar warranty. What really matters with the installation of new equipment is the quality of install. To this point, “off-brand” equipment installed properly can outperform “name brand” equipment installed improperly.

Life expectancy of a unit is directly related to the quality of the original installation, as well as regular annual maintenance. Systems that were installed and maintained properly will outlast systems that were not. Average life expectancy is 14-16 years.
