The primary purpose of a whole-house humidifier

Help and maintain consistent moisture levels throughout every room in a home. Directly connected onto the existing HVAC system, it automatically adds humidity that is circulates through the ductwork.

Health and Comfort Benefits

By keeping indoor humidity within the ideal range of 35% to 50%, these systems help alleviate many issues caused by dry air.

Respiratory Relief: Moisturizes nasal passages and throats, which helps soothe symptoms of colds, flu, allergies, and asthma.

Skin and Eye Care: Prevents dry, itchy skin, chapped lips, and irritated eyes common in dry winter months.

Improved Sleep: Helps reduce snoring by keeping the soft palate and nasal passages moist.

Static Reduction: significantly reduces static electricity, preventing uncomfortable shocks and protecting sensitive electronics.

Protection for Home and Belongings

Maintaining proper humidity levels is essential for preserving the structural integrity and appearance of your home.

Wood Preservation: Prevents wood floors, furniture, and cabinetry from shrinking, warping, or cracking.

Musical Instruments: Helps safeguard delicate items like pianos or wooden guitars that are sensitive to dry conditions.

Plant Health: Creates a better environment for indoor tropical plants that struggle in dry air.

Energy Efficiency and Cost Savings

Humidified air holds heat more effectively than dry air, which can lead to direct utility savings

Perceived Warmth: Moist air feels warmer, allowing you to set your thermostat 1 to 2 degrees lower while maintaining the same level of comfort.

Lower Heating Bills: According to the U.S. Department of Energy, lowering the thermostat by even one degree can reduce heating bills by up to 4%.

Whole-House vs. Portable Units

Unlike portable units that require manual refilling and only cover a single room, whole-house systems offer several advantages.

Automatic Operation: They connect to the home's water supply and are controlled by a humidistat, eliminating the need for manual refills.

Quiet and Discrete: The units are installed in the HVAC system (typically in the basement or attic), making them much quieter and "invisible" compared to room models.

Minimal Maintenance: Most whole-house models only require a filter or water panel change once a year.

This was a major project and a big relief for the customer. The system is designed to heat the home using in-floor radiant heating. Due to flaws in the original system design, the customer experienced numerous major and minor repairs.
The solution was to completely remove the existing system, including all piping and circulating pumps, and redesigned from the ground up. As shown in the photos, the new design is engineered for efficient operation, improved reliability, and whisper quiet performance.

This project involved replacing an older 80-gallon electric water heater that had started leaking.I upgraded the system to a 50-gallon electric heat pump water heater, which is 3-4 times more energy efficient than a traditional electric water heater. The new water heater has a bumper to bumper ten year warranty.

🔥 Furnace Friday — Water Heater Edition! 🔥
Most homeowners forget about their water heater… until it stops working.
A little maintenance goes a LONG way in protecting your system (and your hot showers).

💧 Quick Pro Tips:
• Your water heater needs yearly maintenance, just like your furnace.
• Flushing the tank removes sediment that forces your system to work harder.
• Inspect the anode rod (sacrificial rod) every few years — it prevents rust and extends the life of your tank.

At MARCOR, we believe in educating homeowners so your system lasts longer, runs safer, and stays efficient.
If it’s been over a year since your last check-up… it’s time. 👍

Most of the system in my neighborhood are getting old. It was time to replace the old system with something more efficient and up to date.

Had a customer with a Noritz tankless water heater, it had a 4 inch exhaust pipe and was only 84% efficient.

I replaced the Noritz with a new and improved Rinnai, which has a 2 inch intake and exhaust pipe and is 98% efficient.

This is the before and after. Bosch systems are a great product.
Inverter heat pump/ it uses the outside system to heat and cool the home. The gas furnace can be used as an optional heat source
Variable compressor and fan speed, it will adjust it speed based on demand.
Energy-efficient and many more
I thought I was going to be the first person with an installed Bosch system, but one of my customers had me install one for him before I could install mine.
