According to a study of 6000+ homeowners, conducted by the Home Improvement Research Institute (HIRI), HVAC maintenance and repair was the third most required service after pest control and gardening. Given that HVAC breakdowns are frequently unexpected, it’s not uncommon for homeowners to choose whichever repair company they come across first in an emergency. However, the reality is technical skills, professionalism and prices differ in the HVAC industry, so there’s a risk that a last-minute choice might result in disappointment. Unlike some other companies in our sector, our engineers are certified by the most nationally recognized HVAC certification and training organization: NATE (North American Technician Excellence).

NATE-certified engineers have a range of advantages:

  • Adept at maintaining, repairing, and diagnosing any type of HVAC equipment as a result of meticulous, structured training
  • A solid understanding of how to get the job done in the most time-efficient manner
  • Proficiency in working with new HVAC products and emerging technologies
  • Fewer warranty returns and call-backs as they know how to do the job right the first time
  • Frequent in-house training guarantees the engineer’s skills are maintained to the highest standards and always in accordance with NATE’s requirements

When choosing which HVAC company to hire, it’s essential you know how to determine whether their staff are reliable and qualified. Knowing how to ask the right questions is the most sure-fire way to eliminate any unqualified companies. Whether you’re in Colorado or out of state, make your search easier by downloading our guide to finding the right HVAC company.


Aurora Heating and Cooling

Winter temperatures in Aurora average 23°F and exceed 90°F in summer, so maintaining a reliable HVAC system will secure your comfort year-round. Without one, there’s a risk of surprise breakdowns. If your setup isn’t running optimally, or fails altogether, you also risk:

  • Wasting money running high-wattage appliances, such as a portable heater, to combat the effects of a neglected HVAC system.
  • Fires caused by foreign objects, such as plastic fragments, or faulty electrical wiring.
  • Heat loss caused by leaks. On average, homes lose $300 annually to leaks, outdated equipment, and drafts, according to the Office of Energy Efficiency & Renewable Energy.
  • Irregular or unusually high energy bills. An Energy Information Administration study estimates natural gas heating bills will average nearly $750 in 2022. Compared to last year, this is a 30% increase, so it makes good sense to ensure your HVAC setup is performing properly and not hemorrhaging cash.
  • Damaged furnace components, like capacitors or fan belts. When these parts fail, the blower motor overheats, which leads to cracked heat exchangers or melted casings.
  • Health issues caused by dampness, allergens, or mold growth.

HVAC Services in Aurora

We take on any type of HVAC work, from replacing worn-out furnace parts in homes to specialist duct installations in commercial properties.

Here’s what we do:

Aurora Home Air Quality

Your health and wellbeing are directly linked to your home’s indoor air quality. Routine HVAC maintenance reduces the number of allergens and dust circulating around your ductwork and also improves your system’s overall performance.

HVAC Maintenance Check

Dry air also affects indoor air quality. It causes a range of minor, but irritating, ailments if left unchecked, such as:

  • Chapped lips
  • Dry skin and throat
  • Sinusitis
  • Nosebleeds

In more serious cases, dry air aggravates bronchitis and asthma. It also damages your home’s interior, leading to:

  • Flaking wood
  • Chipped plaster
  • Paint and wallpaper failure

Our guide, How to Fix Dry Air in your Home, includes helpful ideas for raising your home’s humidity, the benefits of humidifier units, and the signs of dry air at home.

Without a doubt, CO (carbon monoxide) poisoning is the biggest air quality issue all homeowners should protect themselves against. More than a third of carbon monoxide-related deaths happen between December and February as people close sources of ventilation, such as windows, to reduce drafts and increase warmth. Everyone should be familiar with the causes and symptoms of carbon monoxide poisoning. If you aren’t, read our overview about carbon monoxide in homes.

To arrange for a technician to maintain, repair, or install a CO detector, dehumidifier/humidifier, or HVAC ductwork, contact us today. We also offer free advice on how to improve indoor air quality and conduct whole-home tests to detect:

  • Asbestos
  • Allergens
  • Volatile organic compounds (VOCs)
  • Bacteria and mold
  • Combustive elements
  • Radon
  • Temperature and humidity in individual rooms

Aurora Air Conditioning

Aurora’s most popular home cooling systems are:

  • Floor-mounted air conditioners
  • Window-mounted air conditioners
  • Ductless mini-splits
  • Wall-mounted air conditioners
  • Central air conditioners
  • Evaporative cooling systems

In addition to maintenance and repair services, we offer air conditioning installation in Aurora. Our technicians are NATE-certified and experienced with all makes and models of air conditioning equipment, and we’re an authorized Carrier dealer. We install and maintain all four types of heat pumps too: water source, geothermal, air-to-air, and hybrid.


Despite their name, heat pumps are a great method for cooling your home and can save you 50% on your electricity bill. To learn more about how heat pumps function, and their pros and cons, check out our heat pump FAQs.

Home Heating in Aurora

Few things are more irritating for homeowners than a mid-winter HVAC breakdown. You can limit the risk of problems occurring by servicing and regularly maintaining your setup before winter arrives. You might get away with skipping a gutter clean, but don’t be tempted to put off tending to your home’s heating system. If you do, you risk cold nights, needless stress, and expensive call-outs.

From furnace installation to water heater repair in Aurora, our team is available to take on any HVAC work 24/7/365. Our technicians are experienced with smart vents, smart thermostats, and all types of heat pumps. Complete HVAC replacement costs $7,000 on average, including any ductwork. To determine whether you should replace or repair your setup, check out our HVAC quiz.

Other ways to boost your home’s warmth, aside from replacing or repairing your existing setup, include:

  • Closing your curtains at night and using thermal curtains to reduce heat loss
  • Sealing cracks and gaps with weather-stripping, insulation, or caulk
  • Using rugs or carpets to improve floor insulation
  • Reversing your ceiling fan so it pulls warm air from your ceiling downward
  • Creating a customized heating-cooling schedule using a smart thermostat that automatically adapts to any weather changes
  • Cleaning your HVAC air filters to prevent your system from ‘short cycling’, which is when the system gets stuck in an endless loop of overheating, shutting down, and restarting
  • Opening doors to bathrooms and kitchens, when in use, to allow warm air to circulate around the home and replace any cold air
  • Blocking your chimney to prevent drafts
  • Uncovering south-facing windows on sunny days to let solar heat in

Aurora Home HVAC Inspections

HVAC setups get the heaviest use in winter and summer. We can inspect your system before the season starts, and repair and maintain any essential components. Our inspections cover:

  • Checking the ignitor switch’s electrical resistance with a multi-meter
  • Smoke and carbon monoxide detector safety checks
  • Inspecting ducts, vents, flues, and filters are free of obstructions and in good condition
  • Checking that furnace parts, such as the interior casings, are dust and dirt free

For those looking to buy or sell a home, we also offer full HVAC inspections so buyers can be confident the setup is in safe working condition and are aware of any impending repair costs. The inspection typically takes less than three hours to complete and costs under $500. It is no surprise that replacing HVAC equipment is a formidable home expense. However, with a pre-purchased home HVAC inspection, you can plan ahead and adjust your budget accordingly.


Our inspection team will also look for other issues that could affect your home’s comfort and temperature regulation, such as clogged drains, dampness, roof leaks, and inadequately insulated water lines. Further details of what they cover are included in our blog: Why You Need an HVAC Inspection in Denver.

Contact us today to schedule an inspection.

Aurora Ductwork Repair

We fix all types of ventilation and air transmission parts, from rigid and flexible ducts to seals and fittings. According to ENERGY STAR®, homeowners lose a third of their duct air to leaks. Fortunately, spotting ductwork leaks is easy.

Look out for:

  • Bent, rusted, or crushed ducts
  • Increasing or excessive accumulations of indoor dust
  • Unevenly cooled (or heated) rooms
  • Busted seals
  • Cold or hot spots on dry wall
  • Low air flow
  • Fumes wafting up from the ground floor or basement into rooms
  • Unusually high energy bills
  • Humming noises

We employ a range of methods to improve & repair ductwork:

  • Conducting airflow and duct leak tests
  • Installing duct insulation in unconditioned spaces to limit heat loss and improve HVAC performance
  • Balancing airflow by installing transfer grilles or jumper ducts
  • Sealing ducts with sealant or aluminum foil tape

We also offer duct cleaning services, which reduces allergens and airborne irritants, removes unpleasant smells and odors, and enhances air flow at home.

Aurora Ductless Heating and Cooling

Is there a part of your home not currently serviced by your HVAC system, such as the attic or garage? If so, it’s not uncommon as areas like these are rarely large enough to accommodate traditional bulky ductwork, and are frequently used for storage instead. Fortunately, with ductless HVAC technology, which is more compact compared to older ductwork, you can now add heating or cooling to these spaces. According to a 2020 study by HomeLight, room conversion adds $10,000 to your home’s resale value. Considering ductless HVAC costs as low as $5,000, you won’t struggle to get back what you’ve paid when it’s time to sell your house.

Unsurprisingly, there’s no ductwork in a ductless setup, neither outdoors nor indoors. Instead, the system uses an indoor air handling unit and an outdoor compressor. The units are linked with a three-inch diameter conduit containing a drain line, refrigerant pipe, and cables for power and control. On average, this option takes only 1–2 days to install. From maintenance and repair to installation and construction, we offer a full range of ductless HVAC services.

The average age of Aurora real estate is 40 years old. Although solidly built, older properties frequently have higher maintenance costs. The American Society of Home Inspectors says that 30+ year-old homes require 3% of their original purchase price to maintain annually. For example, if you paid $100,000 for your house 30 years ago, you can expect to pay up to $3,000 per year to maintain it.

When you factor in that ductless uses at least 30% fewer watts per hour compared to ducted versions, and the 11.46¢/kWh average cost of electricity in Colorado, it’s easy to see how going duct-free can save you hundreds of dollars annually.

We repair, maintain, and install all types and makes of ductless HVAC units. To learn more about benefits and which homes are best for this option, we offer a guide for assessing your home's suitability for ductless.
