How Heating Systems Have Changed

Heating technology has come a long way in recent decades! Today's furnaces and boilers are vastly more efficient, intelligent, and comfortable than older designs. Some of the improvements include:

  • High-efficiency components - New models convert over 90% of fuel to heat, saving energy.
  • Smart controls - Digital programmable thermostats optimize efficiency and comfort.
  • Quieter operation - Insulated cabinets keep sound levels low.
  • Smaller sizes - Compact Impress furnaces fit in tight spaces.
  • Added safety features - Flame sensors, auto shut-offs prevent issues.
  • Zoned heating - Target different areas with smart dampers or multiple units.
  • Healthier air - Added air filtration improves indoor air.
  • Longer lifespan - Quality components provide up to 20 year lifespans.

Today's heating systems heat homes better than ever while using less energy and providing cleaner, healthier air. Upgrading from an older furnace or boiler can pay for itself over time through utility savings while also improving comfort. Our team can advise you on the best replacement for your needs and budget.

How Boilers Keep You Warm

Boilers provide hydronic or steam heat for many homes in our northern climate. Hot water or steam circulates through pipes or radiators to heat rooms individually. This allows zoning so unused rooms don't get heated.

The boiler burns natural gas, propane, or oil to heat water in an enclosed chamber. The hot water then circulates through the system. Boilers provide consistent, even, comfortable heat through radiant heat transfer.

Modern boilers are very efficient up to 95% AFUE ratings. This saves on fuel costs. Large boilers with high BTU capacity can supply sufficient heat for larger homes. Condensing boilers use a second heat exchanger to get even more heat from exhaust gases.

We service all makes and models of boilers. Proper maintenance and tuning keeps boilers running for decades. Call us if your boiler needs repairs or replacement!

What You Should Know about Gas and Electric Furnaces

Gas and electric furnaces have different heating methods but share many of the same components like blowers, filters, and ductwork. Here's a look at each type:

Gas Furnaces

  • Use natural gas or propane for fuel. More efficient and lower cost than electric heat in most areas.
  • Burn fuel in a combustion chamber. Heat exchanger transfer heat to air.
  • Attic or closet installations. Connected to ductwork to distribute warm air.
  • AFUE ratings of 80-98%. Higher is better.
  • Ideal for larger homes, extreme climates.

Electric Furnaces

  • Use electric heating elements. Best for areas with inexpensive electric rates.
  • Compact, wall-mounted units used in smaller homes, additions.
  • No ductwork required - heat and circulate air locally.
  • Lower installation cost than gas furnaces.
  • AFUE not applicable. Use 100% of electricity converted to heat.
  • No combustion or flue required.

We service all makes and models of both gas and electric furnaces. Call us if your existing furnace needs repairs or replacement!

How Heating Systems Have Changed

Air conditioners have seen major improvements in recent years. Today's AC units are more powerful, efficient, and smart. Upgrades include:

  • Higher SEER ratings - 17-24 SEER models available for lower cooling bills.
  • Quieter - Improved fan designs move air quietly.
  • Healthier air - Systems filter out allergens, pollutants as they cool.
  • Smart controls - Programmable thermostats optimize settings.
  • Compact sizes - Smaller condensers and evaporators fit anywhere.
  • Enhanced airflow - Variable speed blowers for even distribution.
  • Zoned systems - Target different areas of home.
  • Ductless options - Cool additions or rooms without ductwork.

Investing in a new efficient air conditioner can save up to 40% on energy costs while keeping your home cooler and more comfortable on hot Indiana days. Call the team at M.N. Heating & Air if your existing AC unit needs repairs or replacement!

How to Find Commercial HVAC Technicians

Business owners have unique needs when it comes to HVAC service, maintenance and equipment. Here are tips on finding commercial technicians:

  • Ask about commercial experience - Not all technicians work on large commercial systems. Find those with expertise in commercial repairs and installations.
  • Inquire about certifications - Many brands require special commercial tech certifications. Make sure your tech is certified for your equipment brand including Carrier, Trane, Lennox, Daikin and more.
  • Ask about experience with your system type - For example, rooftop systems, chillers, VRF systems, boilers, furnaces, etc. You want techs knowledgeable of your specific equipment.
  • Find a licensed commercial contractor - In Indiana, contractors working on commercial systems must hold a state commercial HVAC license. This ensures expertise.
  • Get references - Ask for references from other local businesses the company has served. This proves they can handle commercial work.
