Saving Money & Energy Efficient

You’re looking into purchasing a new AC unit and keep hearing the phrase “SEER Rating”. The Office of Energy Efficiency and Renewable Energy states that heating and cooling account for 55% of the energy used in residential homes. Energy prices aren’t getting any cheaper, therefore, maximizing efficiency is an excellent way to keep money in your pocket at the end of each month. Learn what that means, and how your SEER rating relates to buying a new furnace and air conditioner.

What is a SEER Rating?

All HVAC systems have SEER ratings which stand for Seasonal Energy Efficiency ratio. This ratio allows individuals to determine the efficiency of an AC system. The higher the final number is, the more efficient.

The average production of an air conditioning unit is measured in British Thermal Units or BTUs, and the average energy expended is measured in watts. The result will be a number from 6 to 23. The most popular systems boast a SEER of 20 or higher. A system with a SEER of 20 would use 1/20th of energy as one with a SEER of 10, even though they may have the same output.SEER ratings are only used to determine the energy efficiency of air conditioners and home heat pumps

An HVAC unit that has a higher SEER is often due to two components that provide greater indoor comfort.

  • 2-stage or variable-speed compressor
  • Variable-speed blower

Differences Between Single-Stage and Two-Stage HVAC systems

Air conditioners with lower SEER ratings are usually single-stage and only run on one speed. This means they’ll frequently turn on and off during mild weather and you’ll experience uneven cooling or hot and cold spots. Y

You’ll also experience higher humidity levels which makes it feel hotter than it is. Your A/C needs to run for a long period of time to remove humidity from your home’s air. A single-stage system’s ups and downs don’t accommodate this, and it might require maintenance for them to run comfortably.

Price of a Two Stage HVAC system

It’s a trade-off, the higher the SEER rating now equals lower costing energy bills for years to come. 
The SEER rating of an air conditioning unit is one of many features that have an effect on the price.  Higher-performing units can be more costly than older units or units for each increase in SEER rating, expect to pay anywhere from $350 – $1500

Minimum SEER Ratings For HVAC Units in Minnesota

Between extreme weather swings and Increases in energy cost, living in Minnesota, we know the importance of having an energy-efficient HVAC system to deal with the heat and the humidity.   The Department of Energy determined in 2015 that starting in 2023, the SEER minimum in Minnesota should be 14 to keep up with both increased energy costs and warming trends.

The Problem: Water Dripping From Your Air Conditioner

You walk outside your home on a hot summer day and notice that your AC leaking water.

 You’ve never noticed this before and you still have cold air coming out of the air conditioner, is this just what happens or is this a sign of a bigger problem?

This is a common home cooling problem. Before you panic — here are a few of the reasons and possible causes for your air conditioner leaking water.

AC Leaking Water

Reasons Your an AC Leaking Water

  • Your Filter is Clogged – If your filter is dirty, the air won’t be moving efficiently through your system. This can cause ice to form on your unit’s evaporator coils. When the ice melts, you’ll see a puddle of water underneath it. Check your filters periodically (about once a month) to make sure that your filter is not clogged and that the unit is working efficiently.
  • The Overflow Pan is Damaged – The overflow pan is designed to catch any condensation from your air conditioning unit. This is especially important on hot, humid days!  If there are small holes or cracks in your overflow pan, you may notice the water leaking through
  • The Condensate Line is Clogged – This is the most common cause of air conditioner leaks. When the condensate line is clogged, water will back up and flood the overflow pan.

These are all issues that can be fixed by a professional HVAC technician.  Give us a call at Dean’s Home Services, we provide air conditioning services for the entire Twin Cities.  From Lakeville, MN to Forest Lake, MN, and everywhere in-between, Call Dean’s today to fix your AC problems.

Worried about your home’s air conditioning, here are three signs to look for when determining if it’s time to replace your air conditioner. During a Minnesota summer, we’re all spending more time outside, the one thing we need the most is air conditioning and while the days areonce again getting shorter, we aren’t done with the heat!

Poor Airflow

Poor airflow in your home can be a sign that the compressor in your air conditioning unit may be failing. Do you have a hard time keeping your home cool? This could be the sign of an aging air conditioner or even an incorrectly sized system. An HVAC technician from Dean’s Home Services will be able to quickly diagnose this issue as well as give you options for fixing it. 

Have You Noticed Your Energy Bills Increase? 

Higher energy bills can indicate that your air conditioner is either malfunctioning or losing efficiency. Energy bills often start rising as an air conditioner gets older, so the two issues can be related. 

The Air Conditioner is 10 – 15 Years Old

If your home’s AC System needs high-priced repairs or if your air conditioner is 10+ years old, it will often make more sense to replace it rather than repairing it. A newer, more efficient system will save on energy costs.

If you or your child have eczema, you understand the discomfort that flare-ups can cause. You probably also take measures to reduce your chance of an eczema flare-up in the future. If you are still experiencing red, itchy, dry and painful patches on your skin, the source of your eczema symptoms may actually be your indoor air quality.

Humidity Levels

When your home’s humidity level is too low and temperatures are warm, your skin can dry out. On top of these conditions, running your air conditioning constantly during the summer can trigger your eczema and make it harder to get under control without your home being uncomfortable.

Increased Allergens

If you suffer from seasonal allergies or are sensitive to indoor allergens such as pet dander, dust, mites, and mold, your eczema may worsen due to high exposure. If your air conditioner isn’t working to properly filter your air, these allergens will hang around in your home and can cause a major flare-up.

Protecting Your Skin

The easiest way to improve your home’s indoor air quality and decrease your eczema symptoms is by maintaining your HVAC. You can choose filters that can handle trapping large portions of allergens, which will help keep your air clean. To maintain your home’s humidity levels, consider purchasing humidifiers and placing them around the living spaces in your home such as bedrooms. This will help your air conditioner maintain proper humidity levels and adjust to when levels are not ideal.

Additionally, you should always stay on top of regular air conditioner maintenance. Performing regular checks on your AC will help to prolong its lifespan as well as prevent making your eczema symptoms worse.
