- JHJay HallingJul 20, 20225.0Polite, informative, helpful, give options, no pressure, always available.
- AWAriel WolfSep 19, 20195.0I am very happy with my new Bryant furnace installation from MMT Heating. Every interaction I had with them from initial sales contact to the install of my new furnace was great. I was impressed by their knowledge and that they took the time to explain things and I really appreciated their straightforward pricing. I liked that they also followed up the next day after install to make sure that I was satisfied with their work and to see if I had any remaining questions.
- TETony EvansJan 18, 20165.0No other heating specialists would come out and look at my garage furnace to give me an estimate on fixing it. MMT came out and gave me a free estimate on how much it would be to not only fix my current furnace but also gave me very reasonable quotes on how much it would be for a new heating system in my garage.
- CPCharles PleskiApr 19, 20155.0After over 40 years of gathering, cutting, splitting, stacking and feeding the wood stove/boiler, we elected to install a Maxim 250 pellet boiler from Central Boiler. After shopping around, we chose MMT Heating & Cooling for the job. We always do extensive research before we make major purchases. MMT Heating & Cooling came out on top of our list of potential suppliers. Because we already had an outdoor boiler inside a building (separate and removed from other structures) we asked MMT Heating & Cooling to put the pellet boiler inside the boiler shed with the one-ton hopper outside the shed adjacent to the building. We were told it has never been done before, however, they would make it work. And, they did it! We now do periodic maintenance on the boiler inside a warm and dry building. We also store our pellets inside a woodshed out of the weather. We are now approaching the end of our first year using the Maxim 250. We love it! We have three zones going to three buildings (house, garage and shop, and studio); and, we heat our domestic water too. Instead of feeding the boiler twice a day we now feed the hopper once a week. The service from MMT Heating & Cooling has been excellent and they have always responded to our needs. They show up on time on the scheduled day and get the job done. They are polite, courteous and listen to what the customer is saying. We would highly recommend MMT Heating & Cooling to others.
Frequently Asked Questions About MMT Heating & Cooling
Is it a good idea to seal heating registers in my home?
We recommend leaving all your vents and registers open. Closing off registers to rooms you don’t use often causes your furnace system to release air unevenly and overwork itself as a result. By leaving registers open, air flow is allowed to evenly and efficiently heat your house.
How often do I need to replace my furnace filters?
Changing your furnace filter once a year during your annual tune-up is ideal, especially if your home does not have many air quality concerns. If you smoke indoors or have pets or allergies, we recommend changing your filter every six months to maintain cleaner air quality.
Bryant filters are more efficient than the selection at your local hardware store and MMT can help you find a filter for your system that will maximize your furnace’s cycling and airflow. Upgrade to a filter with a high AFUE (Annual Fuel Utilization Efficiency) rating to save money on your utility costs.
Should I purchase a furnace or boiler with a larger capacity for added heating comfort?
Having a larger furnace or boiler installed in your home doesn’t mean your heating comfort will be any better. An oversized unit in your home won’t cycle properly, causing inefficient operation, more out-of-pocket costs and a shortened life cycle for your heating system.
Can an outdoor wood furnace be installed with my heating system?
An outdoor wood furnace can be easily integrated with any existing heating system. Whether you have a furnace or a boiler, MMT can design and install an outdoor wood furnace on your property to make your heating more cost-effective and energy-efficient. Our Duluth customers burn 30-50% less wood with a Central Boiler outdoor wood furnace, helping them save money and lower their carbon footprint.
How long will my furnace or boiler last?
Depending on the system, the average lifespan for both furnaces and boilers is about 15 years. As your heating system ages, it naturally loses efficiency, resulting in higher energy bills. Your system’s lifespan can be extended with routine maintenance from our experts at MMT Heating & Cooling. Keep up with maintenance checkups and plan ahead for a new system before your heat goes out in the middle of a Duluth winter!
What is the best way to conserve energy and reduce my energy bills?
Consider the following options to increase your air conditioning efficiency and reduce energy bills:
Upgrade to a high-efficiency system.
Install ceiling fans.
Schedule routine maintenance checkups.
Keep vents and registers unobstructed.
Install a programmable thermostat.
Adjust the temperature 5-8 degrees up or down depending on the season.
How often should I schedule maintenance on my home cooling system?
We highly recommend annual maintenance for your air conditioning system. Our maintenance includes a tune-up and cleaning to remove contaminants. Our technicians check your system for malfunctions and make sure it is operating efficiently. Tune-ups help you maintain a safe cooling system and extend its lifespan.
How long will my air conditioner last?
AC systems last between 10-15 years on average and can even last 20 years or more with proper care. With regular maintenance, we can keep your cooling system operating efficiently and perform important repairs before they become major issues.
Which cooling system is right for my home?
To properly outfit your Duluth home with an air conditioner, one of our cooling technicians will take measurements and listen to your home comfort needs. We will discuss your budget and assess efficiency ratings to narrow down the options and help you choose the right air conditioning system for your home. We can even help you save money by finding rebates!
What is the most efficient thermostat setting for air conditioning?
The most efficient setting for your air conditioner is the highest temperature at which you are comfortable. We recommend keeping your AC around 76-78 degrees when you are at home and bumping it up to 78-80 degrees while you’re away. Raising your thermostat setting by just two degrees can reduce your overall cooling costs by 5%.
Is it recommended to seal heating registers in the home?
It is recommended to leave all vents and registers open to allow even and efficient airflow, preventing the furnace from overworking.
How often should furnace filters be replaced?
Filters should ideally be replaced once a year during an annual tune-up, or every six months if you have pets, allergies, or smoke indoors.
Does installing a larger furnace or boiler improve heating comfort?
No, oversized units cycle improperly leading to inefficiency, higher costs, and shorter system life. Proper sizing is important.
Can an outdoor wood furnace be integrated with my existing heating system?
Yes, MMT Heating & Cooling can design and install an outdoor wood furnace compatible with your current furnace or boiler for cost-effective heating.
What is the typical lifespan of furnaces and boilers?
Furnaces and boilers usually last about 15 years; routine maintenance can extend their lifespan and maintain efficiency.
