Thornton Heating and Cooling

Thornton’s average temperatures range from 30°F to 75°F. However, we all know that in the extremes, summer temps exceed 100°F and winters drop well below freezing.

With routine HVAC maintenance and ensuring your setup is running optimally year-round, you’ll reduce the risk of expensive and inconvenient emergency call-outs. Plus, you can rest easy knowing that whatever the weather is like outside, you can always count on your home’s indoor temperature to remain comfortable. While skipping HVAC maintenance is tempting, and an easy way to save some money, it’s not worth it as you risk:

  • Fires caused by foreign objects trapped in your duct system or faulty electrical wiring. From 2015 to 2019, home fires caused $7.3 billion of damage across 350,000 properties, according to the National Fire Protection Association. Post-fire, insurance premiums increase by 27% on average, too.
  • Paying up to $300 extra per year due to energy loss from leaks. Poor HVAC airflow also increases the likelihood of using a high energy-consuming heating appliance, like a fan heater, to combat cold spots indoors. These are expensive to run.
  • Broken internal HVAC components, such as a cracked heat exchanger, caused by overheating. Integral parts like this cost several hundred dollars to replace.

From 2021 to 2022, inflation caused natural gas heating bills to rise by over 25%, and electricity increased by 15.8%. If you want to better protect yourself against future energy price rises, looking after and optimizing your HVAC equipment is a wise choice as it limits the risk of costly leaks and parts breaking prematurely.

Thornton HVAC Services  

Whether you want an old boiler restored or a top-of-the-line solar-assisted heat pump installed, we work with all types of HVAC and take on any size project.

Read below for a closer look at what we do, ranging from AC maintenance and home air quality tests, to ductless installations and ductwork repair.

Home Heating in Thornton

Mid-winter heating appliance breakdowns are a nuisance for homeowners. Regular maintenance and servicing are guaranteed ways to reduce the risk of problems occurring during the coldest months of the year. Ideally, do it ahead of winter so you have plenty of time to resolve any issues. While you might get away with skipping less-important tasks, like double-checking your gutters are free of debris, it’s not worth neglecting your home’s heating equipment. Doing so risks expensive call-outs, stress, and chilly nights without heating.

From water heater repair in Thornton to installing furnaces, our team of HVAC technicians is available year-round to assist with all HVAC work. We work with all types of heat pumps too, as well as smart thermostats/vents. If you think your setup is wearing out for good, or are toying with the idea of upgrading your setup for improved performance, try our HVAC repair or replace quiz before deciding. A new HVAC setup costs $7,000 on average, so our quick quiz is worth taking if you want to avoid spending money unnecessarily.

There are other ways to boost your home’s temperature that don’t involve repairing or replacing your setup. For example:

  • Use a smart thermostat to create a customized heating schedule. Some smart setups also adjust automatically to weather changes, so you don’t have to waste extra money and energy heating your home on a warmer-than-normal winter day.
  • Boost floor insulation with thick carpets or rugs.
  • Stop drafts by applying weather stripping to doors and windows, and plugging gaps with caulk or insulation.
  • Use your ceiling fan’s reverse mode, if it has one, to pull warm air trapped at ceiling height downward. 
  • Prevent your HVAC setup from ‘short cycling’ by cleaning any air filters in your system. ‘Short cycling’ is when your HVAC gets stuck in a continual loop of overheating, shutting down, and restarting. While dirty air filters are a common culprit, frozen evaporator coils and loose electrical connections are other causes.
  • Open your shower or oven door after use to circulate warm air around your home and to push out any pockets of cold air lingering indoors. 
  • Close your curtains and windows at night to reduce heat loss.
  • Install thermal curtains to trap cold air drafts and reduce heat loss through your windows by up to 25%. 
  • Ensure south-facing window curtains are open on sunny days to allow solar heat to penetrate indoors.
  • Block your chimney to prevent drafts. 

Air Conditioning in Thornton

The most popular cooling systems used by Thornton businesses and homeowners are:

  • Ductless mini-splits
  • Evaporative cooling systems
  • Central ACs
  • Floor-, wall-, and window-mounted ACs

We offer air conditioning installation in Thornton for all the above types, along with a comprehensive range of maintenance and repair services. Whatever the age or condition of your setup, our team of experienced and NATE-certified engineers is ready to help.

If you’re looking for an alternative to traditional AC, read our guide to heat pumps, which outlines the four types and how they work. According to the U.S. Department of Energy, some models of heat pumps reduce energy use by 30-60%, making them an ideal choice for reducing your energy bills.

Home Air Quality in Thornton

Each year, carbon monoxide (CO) poisoning causes 400 deaths and 50,000 emergency department visits. Although it’s the most serious home air quality issue for homeowners, it’s easily prevented by hiring a professional HVAC technician to conduct annual maintenance and ensuring your home is adequately ventilated, which is especially important in the winter months as this is when people close windows and vents.

If you, your friends, or your family are unfamiliar with the risks, read our short guide outlining the signs of CO poisoning.

Aside from CO levels, indoor relative humidity (RH) also affects home air quality. The ideal indoor RH is 30 to 50%, according to the Environmental Protection Agency (EPA). While RH lower than 30% isn’t life-threatening unless you suffer from chronic asthma or bronchitis, it causes a variety of nuisance ailments:

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

Low RH also damages indoor surfaces, such as plaster, wood, paint, and wallpaper, by drying them out and causing them to flake, peel, or crack. Likewise, RH higher than 50% encourages excessive fungi, bacteria, and mold growth, all of which can be harmful to your health and home’s interior.

As with CO, protecting yourself against dry air is easy with regular HVAC maintenance. Humidifier units are an effective way to control RH levels, too. Read our guide to fixing dry indoor air to learn more about their benefits, how they work, and low-tech ways to control indoor RH.

Levels of radon, VOCs, combustive elements, asbestos, and allergens also affect indoor air quality. We conduct whole-home tests for these, as well as CO and RH levels, and install CO detectors and humidifier units. If you need advice or have any concerns, send us a message.

Ductless Heating and Cooling in Thornton 

Do you have an attic or detached garage that’s not currently connected to your HVAC setup? If you want to add heating or cooling to spaces like these, which often have limited room for bulky ductwork, then a ductless setup is ideal as they’re highly compact. Once fitted, you can make greater use of the space, such as creating a mini-workshop that’s comfortable enough to spend all day in or climate-controlled storage space for precious personal possessions. You can even convert it into a spare bedroom, which adds an average of $10,000 to your home’s resale value. Purchasing and installing one unit costs a few thousand dollars, making it easy to recoup your investment if you decide to sell your property.

Ductless setups are a wise choice for older homes, too, as they consume 30% fewer watts per hour compared to ducted versions. The average age of Thornton property is 30 years old. While older properties are usually well built, they’re frequently expensive to maintain—A 30-year-old property costs 3% of its original purchase price to maintain annually. For a $150,000 home, that means maintenance costs of $4,500 per year.

The lack of ductwork makes ductless HVAC quick and easy to install, taking just 1 to 2 days on average. To learn more about whether this setup is right for you, read our post outlining which properties are best for ductless.

Ductwork Repair in Thornton

Whatever ductwork shape, length, or diameter is installed in your Thornton home, we can repair and optimize it. The services we offer include:

  • Installing jumper ducts or transfer grilles to balance airflow
  • Cleaning ducts to remove odors and harmful contaminants
  • Duct leak checks and airflow tests
  • Patching leaks and restoring ductwork seals
  • Boosting HVAC performance by adding insulation to under-used spaces, such as garages and attics

Wondering if your ductwork is in good condition? Here are some signs that it needs repair:

  • Weak airflow
  • Excessive amounts of indoor dust
  • Uneven room temperatures
  • Strange ductwork noises, such as buzzing or clanking sounds
  • Failing seals
  • Fumes or odors wafting from the ground floor (or the basement) into rooms
  • Cold or hot spots in rooms
  • Higher-than-normal energy bills
  • Damaged ductwork

Thornton Home HVAC Inspections

Planning to purchase a property or looking to sell one? We offer full HVAC inspections to ensure the setup is in safe working order and to identify any costly repairs prior to closing on a deal. Inspecting an average-sized, three-bedroom property typically costs under $500 and takes less than three hours. Considering HVAC is one of the costliest home appliances to replace, a pre-purchase home HVAC inspection is a great way to ensure there are no surprises for either the buyer or seller.

We also offer annual HVAC inspections for homeowners and businesses, to ensure your setup is in good condition ahead of the summer or winter, which is when it gets used most frequently. Our main checks cover:

  • Testing smoke and CO detectors
  • Ensuring ducts, vents, filters, flues, and furnace parts are free of obstructions and in good condition
  • Testing the electrical resistance of the ignitor switch with a multimeter
  • Checking for any issues that could affect your HVAC setup’s performance, such as poor insulation and leaks
