Common HVAC Questions

Whether you’re looking for professional AC maintenance tips or furnace sizing help, we can assist. Our full-service HVAC company is highly professional, and we can answer all the questions you may have about your home comfort needs. From furnaces and boilers to central air conditioners, heat pumps, and ductless mini-split systems, we’ll address them all below:

It’s best to schedule HVAC maintenance services twice a year. Aim for spring maintenance for your cooling system and fall maintenance for your heating system. This tune-up service is necessary to maintain your system’s warranty coverage, prevent costly repairs, and ensure optimal operating efficiency.
Air conditioners typically last for 10 to 15 years, and heating systems typically last for 15 to 20 years. The typical HVAC lifespan depends on numerous factors, including the brand, the amount of maintenance it receives, and your usual usage. Regular system tune-ups can significantly extend the lifespan of your heating or cooling unit.
Appropriately sizing your HVAC system requires a precise formula, or the Manual J formula. This takes into account multiple attributes of your home to determine the ideal heating or cooling capacity for your new HVAC unit. Some of these factors include your home’s square footage, insulation, and layout. It’s best to have one of our professionals determine the appropriate unit size for optimal home comfort and system efficiency.
Your energy bill could be on the rise due to numerous problems with your HVAC unit. Some of the more common culprits include dirty filters, poor insulation, leaky ductwork, or outdated equipment. We suggest scheduling regular maintenance to enhance your system’s performance and keep your energy bills in check.
Most homeowners find they need to replace their HVAC system’s air filter every one to three months. We highly recommend visually inspecting your air filter monthly to see if it needs replacing. If you have pets or severe allergies, you may need to replace the filter more frequently.
If your heating or cooling system experiences a major malfunction, you may be wondering if it’s more cost-effective to replace it. In general, it’s best to replace a system if it’s over 15 years old and your existing warranty coverage has expired. Additionally, if you’re experiencing frequent breakdowns or the cost to repair your unit is one-half or more of the cost of a new unit, upgrade.
There’s no doubt that Minnesota has an extreme climate that can go from freezing temperatures to triple digits, depending on the time of the year. Mini-split systems can be a great option for homes without traditional ductwork. Cold-climate heat pumps provide efficient heating and cooling for all year-round comfort.
We work on all major brands of heating and cooling units. Some of the most common we deal with are Trane, Lennox, Goodman, Carrier, Mitsubishi, and Daikin. Our company is a Lennox Premier Dealer that offers great deals on Lennox-brand products.
Yes, we offer 24/7 emergency AC and heating repair services to all customers in Blaine, Andover, Anoka, and the nearby Twin Cities. It doesn’t matter if your furnace isn’t working or your AC is blowing warm air during triple-digit temperatures. Our technicians will respond quickly to repair your unit and get it back up and running, keeping your family comfortable.
Yes, we offer financing, subject to approval, through our trusted partners for homeowners upgrading or repairing their existing units. Our flexible payment plans are perfect for handling those large, unexpected repair bills. They’re also ideal to make purchasing an energy-efficient system more manageable for your budget.
Yes, ductless mini-split systems are one of the most energy-efficient HVAC systems on the market today. Their room-specific application allows for comfortable heating and cooling without energy waste. Furthermore, their lack of traditional ductwork means there’s no air loss, which contributes to decreased system operating efficiency.
The estimated timeframe for your mini-split installation will vary depending on numerous factors, such as how many zones it will serve. We can install most single-zone mini-split systems in a single day. However, multi-zone systems are more complex and can take two or more days to complete.
