Wherever you live in Littleton, such as a condo in Grant Ranch or an apartment in Columbine, Ultimate Heating and Cooling handles all types of HVAC repair and installation. During our 40+ years in business, we’ve developed an in-depth understanding of the requirements of local homeowners and businesses.

HVAC services are in high demand, with roughly a quarter of heating and cooling appliance owners requiring a repair every year. It’s also the third most requested home service after gardening and pest control. With over 120,000 HVAC contractors in the country, you won’t struggle to find someone to hire. However, prices, professionalism, and technical skills vary in our industry, so it’s well worth your time finding a qualified company. At UHC, our technicians are certified by NATE (North American Technician Excellence), which is the most nationally recognized HVAC certification and training body in the country.

NATE-certified engineers bring a range of benefits to HVAC repair and installation projects:

  • Competent at working with innovative and newly released HVAC products.
  • Lower chance of call-backs or warranty returns as they get the job done right the first time.
  • Maximum value for your money as they’re trained to complete high-quality work consistently.
  • Improved safety, thanks to regular in-house training to ensure their skills are maintained to the highest standard and in line with NATE’s recommend practices.
  • Ability to repair, diagnose and maintain any type of heating and cooling equipment as time-efficiently as possible

Before working with an HVAC company, it’s important to know how to identify a qualified and reliable firm. Our short guide, Questions to Ask your HVAC Contractor, provides tips and essential questions to help with finding the right company for you.

Littleton Heating and Cooling

With summer temperatures reaching 85+°F and winter dipping below 25°F, having a reliable, well-maintained HVAC setup is essential. If your setup isn’t in good condition, you risk stress and inconvenience caused by breakdowns and expensive call-outs. Other impacts of faulty heating and cooling appliances include:

  • Fires triggered by foreign objects lodged in the ductwork or poorly wired electrical equipment.
  • Spending extra money running high-wattage appliances unnecessarily, like a freestanding mini heater, to combat cold (or hot) spots in rooms caused by poorly maintained HVAC equipment.
  • Unpredictable or consistently higher-than-normal energy bills. In 2022, natural gas heating bills rose 30% compared to the previous year. With a healthy HVAC setup, you can rest easy knowing it’s running as cost-efficiently as possible.
  • Leaks causing expensive heat loss. The average US home loses $200 to $400 per year to leaks, inefficient equipment, and drafts.
  • Costly equipment replacement, such as a melted blower motor casing caused by overheating.
  • Health issues triggered by allergens, mold growth, and dampness.

Home Heating in Littleton

Ever experienced a mid-winter HVAC emergency? If you have, you’ll know they’re a total inconvenience. Fortunately, they’re easy to avoid with regular maintenance and annual servicing. Don’t skip it, however tempting, as you increase the chance of needing an expensive callout or equipment replacement.

Whether it’s water heater repair in Littleton or fixing a furnace, we’re available for hire 24/7/365. We work with any type of HVAC equipment, from old boilers to solar-assisted heat pumps and Wi-Fi thermostats. Installing a new system costs at least a few thousand dollars. However, it isn’t always necessary. Avoid replacing your existing setup needlessly by taking our HVAC repair or replace quiz. While UHC never suggests equipment upgrades unnecessarily, there’s no guarantee that another contractor won’t do this, so taking our quiz may save you a considerable amount of money.

However old your HVAC setup is, you can boost and maintain your home’s warmth with these tips and upgrades:

  • Use your ceiling fan’s reverse function to pull warm air trapped at ceiling height downward.
  • Block your chimney to prevent drafts.
  • Clean or replace your air filters at least each season to prevent ‘short cycling,' which is when the HVAC appliance continually overheats, turns off to cool, and then restarts.
  • Lay down carpets or rugs to boost floor insulation.
  • Use a smart thermostat, if you have one, to create a customized heating-cooling schedule.
  • Keep thermal heat in by closing your curtains after sunset. Alternatively, try thermal curtains.
  • Apply foam weather-stripping to door frames and fill gaps and cracks with caulk to stop drafts.
  • Open your kitchen or shower doors, when in use, to circulate warm air throughout the home.
  • Add insulation to your pipes using slip-on foam tubes, which are quick and easy to install. These will lower the chance of your pipes bursting in cold weather.
  • Turn your ductwork dampers, if you have them, so the airflow is set to the maximum level.
  • Put aluminum foil behind any wall-mounted radiators to prevent heat from escaping through the walls.
  • Install duct-booster fans, if you have a forced air heat setup. These increase airflow and make it easier for warm air to reach problem areas of your home.
  • Insulate windows that you don't see out of using bubble wrap. 
  • Install floating shelves above radiators to stop warm air from rising too quickly.

Air Conditioning in Littleton

Littleton’s homeowners and businesses favor the following cooling systems:

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

We provide air conditioning installation in Littleton, as well as a full range of repair and maintenance services. As our engineers are NATE-certified, they’re experienced in repairing all makes and models of AC, in addition to heat pumps. We’re an authorized Carrier dealer too, which is one of the country’s most used AC brands.

For optimizing your home’s energy efficiency in hot weather, read our blog, Energy Saving Tips for Summer. If you’re unfamiliar with alternatives to traditional AC, our heat pump guide outlines how each type works. They can significantly reduce your electricity bill, too.

Home Air Quality in Littleton

Indoor air quality directly affects your overall health and well-being. Dry air is particularly troublesome as it causes a range of irritating ailments, such as sinusitis, chapped lips, and dry throat and skin. Likewise, it also affects your home’s interior, causing flaking wood, chipped plaster, and peeling paint/wallpaper. However, preventing these problems is easy with routine HVAC maintenance. Not only does it keep your home’s humidity at a comfortable level, but it also optimizes your setup’s performance and cuts down on allergens and dust from circulating around your home.

For tips on improving your home’s indoor air quality, our Fixing Dry Air in Winter guide covers how to increase your home’s indoor relative humidity, the benefits of humidifier units, and the signs of poor air quality.

Carbon monoxide (CO) poisoning is another air quality issue homeowners need to be aware of and the most important one by far. Every year, there are hundreds of CO poisoning deaths, with one-third of fatalities occurring in the early winter months. Protect yourself against the risks by reading our guide to carbon monoxide in homes, which outlines the causes and signs of CO poisoning.

Our technicians are trained to conduct indoor air quality assessments. Along with detecting harmful CO levels and indoor relative humidity, our professional indoor air quality tests also look for radon, bacteria/mold, asbestos, combustive elements, volatile organic compounds (VOCs), and allergens. Contact us today to discuss.

Ductless Heating and Cooling Littleton

Do you have a small basement or garage that’s too small to fit traditional bulky ductwork, but you’d like to add heating or cooling to the space? Ductless HVAC is ideal for this, as the duct-free design makes it easier to fit into confined spaces. Once fitted, it adds $10k on average to a home’s resale value. You’ll easily turn a profit too, as it costs as little as $5,000 to install. As there’s no ductwork to deal with, installation is pretty quick, taking just 1–2 days in most cases, and it’s easy to maintain. It’s also highly energy efficient—ducted HVAC uses 3,000 to 3,500 watts per hour and ductless versions use just 2,000 watts per hour.

The average age of Littleton property is 42 years old. According to the American Society of Home Inspectors, maintenance costs for real estate older than 30 years are 3% of its original purchase price. For a $100,000 property purchased new in the 1980s or ‘90s, that means annual maintenance costs of $3,000, which is nearly three times higher than a 10-year-old property.

However old your home is, installing ductless HVAC is a great way to cut down on maintenance costs as they consume 30% fewer watts per hour, compared to ducted models. This means you could reduce your electricity bill by hundreds of dollars per year.

Want to go duct-free, but wondering if it’s right for you? Read our guide outlining which homes are best suited to it: Is Your Home Right for Ductless? We repair and install ductless HVAC too.

Ductwork Repair in Littleton

We repair all types and models of ductwork, ranging from fittings and seals to round or flexible ducts. Our techniques for repairing and optimizing ductwork usually involve sealing ducts with sealant or aluminum foil tape, conducting airflow and leak tests, balancing airflow, and ridding ducts of irritants and allergens.

With a third of duct air lost to leaks, keeping your ducts in good condition is a surefire way to improve your system’s efficiency and lower your energy bills. The main signs of ductwork leaks are poor airflow, unusual noises, unevenly cooled or heated rooms, excessive dust, and fumes wafting around indoors. For questions on ductwork repair or help with stopping a leak, contact us today.

Littleton Home HVAC Inspections

Before summer or winter arrives, which is when HVAC is most heavily used, hire an engineer to inspect your setup. Doing so means any issues and broken parts are sorted before the season arrives. Our inspections cover:

  • CO and smoke detector safety checks
  • Ensuring furnace parts are free of dirt and dust, and that vents, flues, filters, and ducts are in good condition
  • Using a multimeter to check the ignitor switch’s electrical resistance

Are you looking to buy or sell a home, but want to ensure the HVAC setup is in safe working condition? If so, we offer full home HVAC inspections. It typically takes three hours to complete and costs less than $500. Our post, Why You Need an HVAC Inspection in Littleton, outlines all you need to know about the process. To schedule an inspection, send us a message or call us.
