When purchasing a new air conditioning system, it is essential to make an informed decision. According to Google snippets, "Ensure you invest in an energy-efficient model with a SEER rating that meets your budget and cooling needs. Consult a professional to help assess the correct size of the unit based on your home’s square footage." Below are detailed tips by AMS A/C & Heating to help you make the right choice, save on energy, and cut costs.

1. Consider More Than Just Cost
Don’t be swayed by the lowest or highest bids. Understand what you are paying for. Bids for new AC systems can range from $6,000 to $20,000.
2. Avoid “No Name” Systems
Do not be tempted by a no-name AC system, even if it offers a 10-year warranty. Replacing a faulty compressor can cost upwards of $1,000.
3. Replace the Entire System
If replacing an existing air conditioner, replace the whole system, including the inside coil and furnace, to achieve rated efficiency.
4. Understand the Specifications
Ensure your HVAC contractor provides you with the system type (straight cool or heat pump), efficiency rating (ask for a copy of the AHRI Certification), system size (tons), available rebates, and warranties (including labor warranty for part replacements).
5. Verify AHRI Certification
Once you receive the HVAC contractor’s bid, request a copy of the AHRI Certification. If the contractor doesn’t know what it is, find another contractor.
6. Review the Certification
Ensure the AHRI Certification matches what the contractor claims. It should include:
- System efficiency
- Equipment model numbers
- System size (tons or BTUs)
- System type (straight cool, heat pump)
Be wary of contractors who mislead about the system's efficiency rating.
7. Analyze Electricity Consumption
Ask your contractor for a written electricity consumption analysis for each option. If they only promise a percentage saving without documentation, look elsewhere. See AC SEER Ratings for more details.
8. Invest in High-Efficiency Units
Federal law mandates new air conditioners have a minimum SEER2 of 13.8. Although more expensive, a unit with at least 16 SEER2 often pays for itself in energy savings over time. See AC SEER Ratings for additional information on AC electricity consumption.
Understanding the Air Cooled Reflux System
The rising need for safety and sustainability in chemical laboratories has led to the development of air-cooled reflux condensers. The Findenser™ by Heidolph offers an efficient air-cooled reflux system.
What are the advantages and disadvantages of reflux condensers? And what factors should be included when buying one? The Heidolph 'Reflux Condenser Buyer’s Guide' answers these key questions. For further assistance, Heidolph Customer Support is available to help.

Why Use Refluxing?
Refluxing accelerates chemical reactions by maintaining high temperatures while preventing solvent loss through evaporation.
Air Cooled vs. Water Cooled: Differences
The refluxing principle involves boiling vapor rising in a column where it condenses and returns as liquid. Water-cooled condensers often use tap water to cool the column, while air-cooled versions rely on ambient air, requiring a larger surface or advanced designs like the finned aluminum jacket of the Findenser™.
Water cooled: Typically uses tap water flowing around the reflux column. Convexities in the inner walls increase the cooling surface.
Air cooled: Heat exchange occurs on the glass column's outer surfaces in basic models. The more advanced Findenser™ design uses a finned aluminum jacket for higher efficiency.
Safety in the Laboratory
Air-cooled reflux condensers eliminate the risk of flooding from loose hoses, making them safer and requiring less space in a fume hood compared to water-cooled systems.
Water-cooled systems can cause extensive damage if flooding occurs, but air-cooled systems negate this risk by eliminating the need for tubing.
Water Consumption and Cooling Costs
Water-cooled condensers can use up to 150 liters of water per hour, increasing operational costs. Recirculating chillers or central systems help but still impact energy balance negatively. To learn more, visit air cooled condensing unit.

Broad Application Range
While conventional air-cooled condensers have limited use due to low cooling capacity, the Findenser™ is designed to handle around 95% of chemical syntheses, suitable for most solvents used.
The Findenser™ efficiently cools solvents such as:
Hydrocarbons: e.g., cyclohexane, pentane, hexane, heptane.
Chlorinated solvents: e.g., dichloromethane (DCM), chloroform.
Alcohols: e.g., ethanol, isopropanol, methanol.
Aromatic hydrocarbons: e.g., benzene, toluene, xylene.
Miscellaneous: e.g., MTBE, acetone, THF, ethyl acetate, acetonitrile, DMF.
For solvents with boiling points up to 155°C/311°F, consult Heidolph Customer Support for any concerns.
Testing for Solvent Volume
Standard air-cooled condensers may not efficiently handle larger volumes of volatile solvents. The Findenser™ can also reach its limits under such conditions. Always perform tests under real conditions with volatile solvents, ensuring safety by working in a fume hood.
Essential Temperature Control
Accurate temperature control enhances the efficiency of the Findenser™. Set the heat source 10-15°C (50-59°F) above the solvent’s boiling point to avoid boiling over and damaging samples. For digital temperature management, contact Heidolph Customer Support.
Suitable for Various Ambient Conditions
Air-cooled condensers, unlike water-cooled models, are more sensitive to ambient temperatures. Performing reflux in a fume hood ensures room temperature does not affect results and enhances safety.

Good Price/Performance Ratio
Basic reflux condensers are affordable, but consider long-term water and energy costs. Safety also plays a crucial role—flooding risks could result in significant damage. Accurate temperature control with external sensors is important for optimal performance.
