  • Which air conditioning services does Blue Sky offer?

    No matter what is going on with your air conditioning, we’ll work with you to help you find the right solutions for your needs. We can fix your air conditioner, replace it with a new one, and install any parts you need to have installed. We’ll make sure you have the cool air that you and your family need so you can live well all summer long.

  • What is the best type of air conditioner for me?

    Most people think of traditional air conditioners when it comes to cooling their homes. However, there are actually many options when it comes to getting you and your family comfortable during the summer. Your options include:

    • Central air conditioners
    • Window air conditioners
    • Portable air conditioners
    • Heat pumps
    • Ductless mini-split air conditioning systems

    Every situation and every person requires a different type of air conditioner. Our experts will take a look at your situation, talk to you about your cooling needs, and then recommend the type or types of air conditioner that we think would work best for you.

  • Should I call for AC maintenance?

    We offer comprehensive air conditioning maintenance. However, a lot of homeowners aren’t sure why they would ask for this service because they aren’t sure how it benefits them. Here are just a few of the things you can gain when you call us for A/C maintenance.

    • A more efficient air conditioner. Make your air conditioner use energy better, which will lower your bills every month.
    • Stay cooler at home. Your air conditioner may be able to process more cold air after it gets tuned up, which means that it will be more effective at cooling your home.
    • Avoid major A/C problems later. Find any potential air conditioning issues before they cause a major malfunction and get them fixed before you need to rely on your air conditioner again.
  • How do I clean my air conditioner?

    Cleaning your air conditioner can be a great way to keep it running well and make sure that it isn’t working so hard that it experiences extra wear and tear.

    1. Turn off the air conditioner and flip the circuit breaker so it’s not getting any power.

    2. Remove the cover on your outdoor unit.

    3. Use a condenser cleaner to clean your condenser coils. Follow the directions on the bottle to achieve maximum cleanliness.

    4. Change your air conditioning filter.

  • Do I need a new air conditioner?

    Not sure if it’s time to buy a new air conditioner? Our experts will come to take a look at your current one and let you know what they recommend. We usually tell people to get a new A/C under the following circumstances:

    • Your current air conditioner is near the end of its lifespan and you’re concerned about an emergency breakdown or our technician thinks that a breakdown is near.
    • You need to fix your air conditioner and the repair will cost more than half the cost of replacing the unit.
    • You’ve been calling frequently for A/C repairs and you’re tired of the hassle or you feel like you’ve spent too much money on smaller repairs.
  • How can I spend less on cooling costs?

    When your air conditioner is working efficiently, you won’t have to spend as much on cooling costs. Here are a few tips for making your air conditioner work better:

    • Change your filter regularly. When your filter is dirty, your air conditioner has to work extra hard to get the air that it cools.
    • Use a programmable thermostat or one you can control with your smartphone. This allows you to keep your home warmer when you aren’t there while still lowering the temperature before you get home.
    • Check your insulation. Insulation isn’t just for the winter! In the summer, it can keep your cool air inside and the warm air outside so you can stay more comfortable for a longer time.
  • Do I need air quality testing?
    Are you concerned about your indoor air quality? Do you want to breathe high-quality air and you’re not sure if you’re doing so? Then air quality testing might be right for you. We recommend air quality testing if you’ve had construction in your home or in nearby areas. You may also want to have your indoor air tested if you’re struggling with allergies and asthma when you’re in your home. We can test for all sorts of contaminants, then let you know what we find, and design an air filtration or purification system that will address your specific needs.
  • What does Blue Sky offer when it comes to heating services?

    We will take care of any problems that you have with your heating system. No matter what kind of heating you have, we have experts on staff who understand your system and get you warm again soon. We’ll handle any repairs, replacements, or installations that you need to have done to keep your home functioning well and everyone inside it comfortable.

  • How can I maximize my heater’s efficiency?

    No one loves to pay high heating bills. Here are a few things you can do to make sure your heater is working optimally this winter:

    • Change your filter regularly. Our experts can tell you how often this is for your heater and your home, or you can change it once every 1-3 months. Make sure your insulation is optimized. You should have plenty of insulation to keep your warm air in and not let it escape.
    • -Consider other heating sources. Use space heaters if you only want to heat a small part of your home at once. Get your heater tuned up. Our tune-up service includes cleaning out your heater so that it doesn’t have to work so hard, which means it won’t use as much energy.
  • What can I do to make my heater safe this winter?

    Are you concerned about heating safety this winter? If you want to make sure your heater is safe, here’s what you can do:

    • Do not close more than 20% of the heating registers in your home.
    • Use a carbon monoxide detector. This will ensure that your gas furnace is burning natural gas properly and is not releasing dangerous gases into your house.
    • Check your pilot light. If your pilot light goes out regularly or changes color, it’s time to bring in a professional. Your gas line may be malfunctioning or there may be a stream of air getting into your furnace. Gas problems are nothing to laugh at, so bring in a professional as soon as possible.
  • When do I need a new heater?

    If your heater is near the end of its lifespan and/or isn’t working the way you need it to, call Blue Sky today to ask about getting a new heater. Our experts will evaluate your current heater and let you know what we recommend. In general, we often recommend a new heater when:

    • Your current heater needs repairs that cost more than half of what it would cost to replace it.
    • You have had to call for frequent repairs and it seems like your heater is wearing out.
    • Your heater is near the end of its lifespan and you are concerned about breakdowns.
    • Your heater cannot effectively heat your home.
  • How can I save money on heating this winter?

    It’s easy to save money on heating when you make sure that your heater is working as well as it possibly can.

    • Consider lowering the temperature. Turn down the thermostat until your family starts to notice that it’s colder.
    • Get a programmable or smart thermostat. These allow you to keep your home cooler during the hours when you aren’t there while still warming it up by the time you get home.
    • Make sure your heater is working efficiently. See the tips offered above for how to do this.

  • What are the benefits of furnace maintenance?

    We recommend annual furnace maintenance in Denver. Sometimes, customers ask us what they stand to gain from this service. Here are just a few of the benefits you could have:

    • Improved heating, especially in rooms that are often too hot or too cold.
    • Use less energy because your heater will work more efficiently.
    • Spend less on heating costs because you’re using less energy.
    • Find potential problems with your heater and get them fixed before they cause major heating breakdowns. 
    • Make your heater last longer because it won’t experience as much wear and tear.
  • How long does a furnace last?
    Many furnaces come with a lifespan of around 20 years, however depending on how often you clean and maintain your furnace it could be shorter. A good rule of thumb is to start thinking about replacing your furnace after 15 years. Annual maintenance can increase that number, and an experienced furnace technician will be able to tell you the estimated lifespan during a tune-up.
  • What type of furnace is best for me?

    There are 4 main types of furnaces available in most residential homes: Natural Gas, Oil, Electric, and Propane

    • Natural gas is a long-term, economical, and energy-efficient option, and a popular option for a well-rounded furnace that works for years to come
    • Electric furnaces are smaller and more budget-friendly, a good option for smaller or remote homes without gas lines running to their properties
    • Oil furnaces are similar to natural gas furnaces, but they are slightly less expensive and less efficient than natural gas furnaces
    • Propane furnaces are the least common but are a great option for more remote locations that do not have a gas line, or anyone preferring to stock up on their own propane to use their furnace


  • What does furnace maintenance include?

    Most furnace maintenance visits include at least 4 things:

    • A visual inspection of your HVAC system
    • A filter change
    • Cleaning out dust and debris from the unit
    • And testing each component of your furnace to make sure it’s working the way it was designed to.
  • What are signs my furnace is going out?

    On average, your furnace can last between 15-20 years if it is properly maintained. However, if you notice any of the following things, it may be a sign that time to replace your furnace:

    • Loud banging, clanking, or squealing sounds coming from inside your furnace
    • You are calling for repairs more often than usual
    • It takes longer for your furnace to heat your house properly, or you find some rooms are colder than others
    • Your energy bills are increasing, even though you’re using your furnace the same amount
    • You smell something rotten, or smell burning even after starting up your furnace for the first time for the year. It is common to smell a slight burning dusty smell the first time you fire up your furnace for the season, but if it continues throughout the year, you may have an issue
    • Moisture accumulating around the furnace or vents
    • Your pilot light is flickering, or turning yellow. This could indicate a dangerous carbon monoxide leak
