Efficient Heating & Cooling Solutions for Your Home
Professional Heat Pump Services in Valparaiso, IN
A heat pump is an all-in-one system that heats and cools your home efficiently. Instead of burning fuel to create heat, it moves heat from one place to another.
In summer: Removes heat from inside your home to keep you cool
In winter: Pulls heat from outdoor air and brings it inside to warm your home
This process uses up to 40% less energy than traditional heating systems, which means lower utility bills for you.

Is Your Ductwork Causing Problems?
Many homeowners don’t realize their ducts are the source of comfort and efficiency issues. Watch for these warning signs:
Temperature Problems
- Some rooms are always too hot or too cold
- Upstairs feels different than downstairs
- Certain areas never reach the thermostat setting
Airflow Issues
- Weak airflow from some vents
- Little to no air coming from certain registers
- HVAC system runs constantly but home doesn’t cool or heat properly
High Energy Bills
- Unexplained increases in heating and cooling costs
- Bills much higher than similar-sized homes
- System seems to run longer than it should
Air Quality Concerns
- Excessive dust throughout your home
- Musty or stale odors
- Allergy symptoms worse indoors than outdoors
Our Ductwork Services
Many homes lose 20–30% of heated or cooled air because of duct issues. The most common problem is air leaks at joints, vents, and damaged areas. This wastes energy, raises bills, and causes uneven temperatures.
Another issue is poor or missing insulation. Ducts in attics, crawlspaces, and garages heat up or cool down, so the air reaching your rooms isn’t the right temperature. The HVAC system then works harder and costs more to run.
Some homes have bad duct design, ducts too small, too long, or with too many sharp turns. This leads to weak airflow and rooms that never feel comfortable.
Finally, disconnected or damaged ducts (crushed, sagging, or separated) can stop air from reaching parts of the home altogether.
Fixing these problems improves comfort, reduces energy bills, and protects your HVAC system.
Our Ductwork Services
Professional Duct Sealing
We seal air leaks using professional-grade mastic sealant or aerosol sealing technology. These create permanent, durable seals that last for decades.
Note: Despite its name, “duct tape” actually performs poorly on ducts. We use materials specifically designed for this application.
Results you can expect:
- 15-20% reduction in energy costs
- More consistent temperatures
- Less dust in your home
- Quieter operation
Duct Insulation
We add or upgrade insulation on exposed ductwork in attics, crawlspaces, and other unconditioned spaces.
Our process:
- Proper R-value insulation for your climate
- Secure installation to prevent gaps
- Vapor barriers where needed
- Professional finish
Typical payback: 2-4 years through energy savings
Duct Repair
We fix physical problems with your duct system:
- Reconnect disconnected sections
- Replace damaged segments
- Reinforce crushed or sagging ducts
- Repair holes and tears
- Secure loose connections
All repairs include proper sealing and insulation to prevent future issues.
Complete Duct Replacement
Sometimes repair isn’t enough. We recommend replacement when:
- Ducts are extensively damaged
- System is improperly sized for your home
- Design is so poor that repair isn’t cost-effective
- You’re upgrading to a new HVAC system
Our approach: We design new systems using industry-standard Manual D procedures, ensuring every room receives proper airflow.
Custom Ductwork for Additions & Renovations
Adding space to your home? We design and install ductwork for:
- Finished basements
- Room additions
- Converted garages
- Home expansions
We don’t just tap into the nearest duct. We calculate airflow requirements, verify your HVAC system has adequate capacity, and design proper duct extensions that maintain comfort throughout your entire home.
Duct Cleaning vs. Duct Repair: What’s the Difference?
Many homeowners confuse these two services. Here’s how they differ:
Duct Cleaning
- Removes dust, debris, and contaminants from inside ducts
- Improves indoor air quality
- Helps with allergies and respiratory issues
- Doesn’t fix leaks or damage
Duct Repair
- Fixes leaks, holes, and damage
- Improves energy efficiency
- Solves temperature and airflow problems
- Reduces energy bills
Most homes benefit from repair first, as it typically delivers more dramatic improvements in comfort and efficiency. We can help you determine which service your home needs.
Benefits of Professional Ductwork Service

Most homeowners save 15-20% on heating and cooling costs after professional duct sealing. For typical homes, that’s $150-$300+ saved every year.

Properly designed and sealed ducts eliminate hot and cold spots. Every room reaches the temperature you want.
Extended HVAC Lifespan
When your system doesn’t work overtime compensating for duct problems, it lasts longer and needs fewer repairs.
