Frequently Asked Questions about HVAC Systems


At Red Line Heating and Cooling, we want to ensure our customers are comfortable. For this reason, we welcome your questions and are more than happy to answer them: there are several popular questions that we are asked frequently about HVAC systems. In today’s blog, we will answer four of our most frequently asked customer questions.

Why Do I Need to Maintain My HVAC System?

Maintaining your HVAC system is one of the best things you can do to ensure it lasts as a long as possible. Regular maintenance can add years of life to your heating or cooling system. Further, it will help ensure your home maintains a healthy air quality. Maintain your HVAC system by regularly changing filters, investing in repairs, and annual maintenance assessments.

Is There Anything I Should Double Check Before Calling Red Line?

Before calling Red Line Heating and Cooling, we encourage you to check a few things. First, check the basics — make sure your cooling or heating system is turned on. If all is well, ensure the breakers and disconnects are turned on as well. If you still can’t identify the problem, check to see if your thermostat is set correctly. While these steps may not resolve any serious HVAC problems, they can prevent an unnecessary service call.

Why are humidifiers used more in heating than cooling?

When cool outdoor air enters your home, it can create dry out the warm air inside of your home. Dry air has the potential to create a number of problems: it can create an uncomfortable climate and trigger a number of health problems, like sinusitis and breathing problems. For this reason, more and more HVAC companies are encouraging customers to purchase a humidifier along with their HVAC system. 

What Does HVAC Stand For?

Interestingly, one of the most common questions we get at Red Line Heating and Cooling is simple, “What does HVAC stand for?”. HVAC is an acronym for Heating, Ventilation, and Air Conditioning. This broad acronym allows us  to work with a wide number of appliances and offer a number of different services.

Was this Winter your Furnace’s Last?

Buying a water heater for your home is an expensive purchase. At Red Line Heating and Cooling, we understand you want to extend the life of your furnace for as long as possible, but at some point it will need to be replaced. It can be tricky to determine when your furnace needs to be replaced, but there are a few things to consider.

So, what dо уоu lооk for when deciding when to replace your furnace? To аnѕwеr thіѕ quеѕtіоn, we must investigate four factors: age, home heating needs, maintenance habits, and home insulation.


Most furnaces last between 15 to 20 years. If your furnace is younger than 15 and experiencing problems, it is wise to speak to a technician at Red Line Heating and Cooling. Our team of professionals can resolve nearly any HVAC problem. Younger furnaces are often insured, or under a manufacture warranty. For this reason, we recommend consulting with your furnace’s manufacturer before contacting us. There is a high likelihood your furnace replacement or repairs will be free.

However, if your furnace is 15 years or older, and it’s experiencing continuous difficulties, it may be time to invest in a new furnace. Replacing an old furnace can often be cheaper than continually paying for repairs, especially if you are only extending your furnace’s life by a couple of years.

Home Heating Needs

The amount of heat you demand from your furnace will impact its life expectancy. If you rely heavily on your heating system it will wear out faster. Individuals who are are more conservative with their heating needs can expect their system to last slightly longer. One way to extend the life of your furnace, and reduce your energy bill, is by investing in insulation.

Home Insulation

Well insulated homes can expect to have lower energy bills and a furnace that lasts. Insulation allows your home to conserve heat and cool air naturally. Ask Red Line Heating and Cooling

about your home’s insulation options. Insulating your home is virtually always less expensive than a new furnace and it saves energy. Home insulation is a viable solution for people who want their furnace’s life to last, reduce their utility bill, and help the planet.

Maintenance Habits

Your HVAC maintenance habits will greatly impact the amount of energy you use each month, and overall, the lifespan of your furnace. Regularly changing your furnace’s filters and investing in an annual maintenance evaluation with Red Line Heating and Cooling, has the potential of adding years to your furnace’s life. For best results, we recommend careful care from the beginning. It easier and less expensive to prevent damage than it is to repair it

Work with our technicians, at Red Line Heating and Cooling, for a furnace that will last. If your furnace is experiencing problems or you would like a evaluation, give us a call: (970) 663-6575. Our customer service team looks forward to hearing from you!

At Red Line Heating and Cooling, we know the HVAC field. We have earned a reputation for superior work and customer service. Red Line Heating and Cooling  is committed to outstanding customer service and job performance. We dedicate our blog to our customers.

Why is My Gas Furnace Leaking Water?

A leaky furnace is an indication of a number of different problems. If your furnace is leaking, and it is not quickly resolved, it may quickly reduce the life of your furnace. You are also at risk of higher utility bills, mold, and other maintenance problems. In order to fix your leaky furnace, you must first know why your gas furnace is leaking. In this blog, Red Line Heating and Cooling, will discuss three reasons your gas furnace may be leaking water.

Clogged Condensate Drain

If water is surrounding your  furnace, there is a good chance the condensate drain is clogged with slime. You can fix this problem with chemical tablets and a larger drain hose, or give Red Line Heating and Cooling a call. Prevent your drain from becoming clogged by fitting the drain tube with an AC condensate pan. Also, regularly maintain your system with slime preventing tablets. Ask the professionals at Red Line Heating and Cooling about these products, we will be happy to help.

High Efficiency Furnace

High efficiency furnaces are more likely to experience leakage, because they regularly depend on condensation to function properly. Condensation occurs  when warm, moist air comes in contact with cold air. This is normally not a problem, unless the hose is blocked or damaged or the drain is clogged. We always recommend maintaining your furnace and investing in annual maintenance checks, but this is especially important if you own a high efficiency furnace.

Issues with the Condensate Pump

Finally, a leaking furnace may be a sign of a broken or malfunctioning condensate pump. A condensate pump is used to pump water in your furnace. Its job is to pump water out to the drain. If you suspect there is an issue with your furnace’s condensate pump, we strongly encourage you to contact Red Line Heating and Cooling. A broken condensate pump can quickly becoming a more expensive, more damaging problem. Work with a team of professionals who are known in the greater Denver, Colorado area for superior workmanship and customers service.

At Red Line Heating and Cooling, we are dedicated to our customers. We are passionate about providing fantastic HVAC services that will keep you and your home comfortable. We have been working in the HVAC community for over seven years. We are dedicated to providing quality service at an affordable price. Please, feel free to give us a call at: 970-663-6575.

What’s a Fair Price for a New Furnace


A new, properly functioning furnace is always going to be relatively expensive, but its price will still vary considerably. The cost of your furnace and the cost of installation can be determined by a number of factors. In this article, Red Line Heating and Cooling will breakdown three factors that will influence the price of your furnace. It is our hope that by reviewing these three factors you may gain a better idea of what is a fair price for your new furnace.

Location and Property

The location of your furnace will impact installations costs. If your furnace is easy to access and work around the naturally it will be less expensive to install and repair. It’s also important to recognize the cost of commercial units are significantly more expensive than residential. The size of your building will also influence the final cost of your new furnace.

Special Features

Naturally, more technologically advanced furnaces will be more expensive. If you select a furnace with more design features (like, multiple speed valves or two-stage operation) will cost more. Our customer service team and technicians will happily help you select a furnace that works well for your home or business, while staying within your budget.


Like most products, the brand of furnace you select will impact your furnace’s cost. Selecting an affordable brand is one of the best ways to reduce the cost of your HVAC system. While many people feel that they need to invest in the most expensive brands, most furnaces functionality is based on their design and installation. If you need to reduce costs, first look at more economical brands.

At Red Line Heating and Cooling, we are dedicated to our customers. We want to help you save money on your HVAC System, without sacrificing quality. Before purchasing your furnace consider your property’s size and location, special features, and brand. Our team of professionals are happy to speak with you, and provide helpful information of furnace costs and installation. If your heating or cooling system is in need of replacement give us a call at: 970-663-6575. Our customer service team looks forward to hearing from you.

How to Keep Pests Out of Your HVAC

Heating and cooling systems come with many modern comforts, but they can attract pests. Pest infestations are never an enjoyable experience, but are often expensive and gross. Luckily, there are measures you and your HVAC team can take to ensure your HVAC system does not attract pests. In this blog, Red Line Heating & Cooling, will share three ways to keep pests out of your HVAC system.

Moisture Contro

Unchecked moisture is a quick way to attracts pests. Pests gravitate towards moist, wet areas. All creatures need water to survive. You can control moisture by using dehumidifiers in bathrooms and other wet areas. It is especially important to ensure the area near your outdoor air conditioning stays dry. If this area becomes wet it can quickly become an attractive home to many different pests.

Seal It

One of the best ways to prevent pests, from your entering your home, is by sealing off pests’ points of entry. You will likely need to contact a  pest control professional to ensure your home is properly sealed. However, our professionals at, Red Line Heating and Cooling., can fit vents with protective screens. These protective HVAC screens will prevent vermin from entering your home. Further, we can pinpoint which drafts may be vulnerable to intrusion.

It is also important to seal your ductwork. Oer time, your duct work will degrade, fail. Gaps in your air ducts can waste energy and create pathways for pests. Consult with our technicians to ensure ductwork is sealed.

Prevention and Maintenance

Perhaps the best way to prevent vermin is through prevention and regular maintenance. Semi-annual professional inspections and tune-ups are the best way to check for signs of pests in your HVAC system. Our team of certified technicians can ensure your home is protected. We recommend having your HVAC system inspected at least once a year.  Red Line Heating and Cooling. is happy to inspect your HVAC system and provide guidance when it comes to pest maintenance. However, we recommend working with a professional team of exterminatiors to eliminate vermin.

Ensure your HVAC system does not attract pests by keeping moisture in-check, sealing  HVAC cracks, and annual maintenance. Red Line Heating & Cooling will help you keep your home and HVAC system pest free. Responsive, personal customer service is at the heart of Red Line Heating & Cooling. We specialize in new and renovation projects for commercial and institutional facilities. We look forward to working with you. You can reach us at: 970-663-6575.

Is it Smart to Simultaneously Replace your Air Conditioner and Furnace?

furnace Repair

Replacing an air conditioner or furnace are typically expensive home investments. Regardless of this pricy expenditure, it is common for HVAC companies to recommend replacing your air conditioner and furnace simultaneously.  At Red Line Heating and Cooling, we strive to help our customers make sound, economically logical decisions. In our experience, it is normally unnecessary to replace your air conditioner and furnace at the same time. In fact, in some circumstances replacing your air conditioner and furnace simultaneously may be harmful to your wallet, and your HVAC system.

With that said, there are three keys circumstances when you should replace your air conditioner and furnace at the same time.


One of the most obvious reasons for purchasing both of these appliances simultaneously is if you live in a remote, hard to reach location. Living in a rural area can make it difficult to set home appointments and find repair companies. If this describes your property’s location, it may be wise to purchase your heating and cooling appliances together.

High Efficiency Air Conditioner

A high efficiency air conditioner requires it to work well with your furnace. While an experienced, skilled technician, can ensure your current furnace works with your high efficiency air conditioner, it is a difficult task. If you are in need of replacing both of these appliances, it is wise to do so together, simultaneously.

Age of HVAC System

If both your air conditioner and furnace are nearing the end of their life expectancy, it may be convenient to replace both appliances together. Most furnaces are expected to last 20-30 years, and air conditioners typically last 10-15 years. Because these appliances vary exponentially in their life expectancy, it may be difficult to replace them both at the same time.

At Red Line Heating and Cooling, we are dedicated to our customers. We want to help you save money  on your HVAC System, without sacrificing quality. If your heating or cooling system is in need of replacement give us a call at: 970-663-6575. Our customer service team looks forward to hearing from you.
