Horizon Services FAQs

A furnace may fail to start because of thermostat settings, a dirty air filter, a tripped breaker, an ignition problem, or another mechanical or electrical issue. Check that your thermostat is set to heat and that the furnace has power. If the system still won’t start, a professional HVAC technician can diagnose the problem and recommend the appropriate repair.

Learn more about furnace repair, replacement, and installation.

Repair may make sense when your furnace is relatively young, has been reliable, and needs a straightforward fix. Replacement may be worth considering when breakdowns become frequent, comfort declines, efficiency drops, or a major repair would require a significant investment in an aging system.

Horizon can evaluate your equipment and help you compare furnace repair and replacement options.

Annual furnace maintenance is generally recommended, ideally before the heating season begins. Routine service gives a technician an opportunity to inspect the equipment, clean key components, identify developing problems, and confirm that the system is operating properly before Colorado’s colder weather arrives.

Ask about Horizon’s Peak Advantage Service Agreement for ongoing maintenance.

Cold air from a furnace can result from thermostat settings, restricted airflow, ignition or burner problems, overheating, or other system issues. If the furnace continues blowing cool air after you’ve checked the thermostat and filter, schedule professional service rather than repeatedly restarting the equipment.

Fuel-burning equipment can produce carbon monoxide if combustion or venting problems occur. Homeowners should maintain working carbon monoxide detectors and have gas-fired heating equipment professionally inspected. If a carbon monoxide alarm sounds, leave the home and follow emergency guidance rather than attempting to troubleshoot the furnace yourself.

An air conditioner can run without cooling effectively because of a clogged filter, airflow restriction, dirty coils, thermostat issues, refrigerant problems, or failing components. Start by checking your thermostat and air filter. If the problem continues, professional diagnosis can identify the underlying cause.

Frequent short cycling can be caused by restricted airflow, thermostat problems, dirty components, improper system sizing, or mechanical issues. Because repeated cycling can increase wear and reduce comfort, it’s worth having the system inspected if the problem persists.

Air conditioners remove moisture from indoor air as they cool. Problems such as a clogged condensate drain, frozen evaporator coil, or drainage issue can cause water to collect around the system. Shut the system off if substantial leaking is occurring and schedule service to help prevent water damage.

Scheduling professional AC maintenance annually, typically before the cooling season, can help identify worn components, address buildup, and prepare the system for summer demand.

The answer depends on the system’s age, condition, efficiency, repair history, and the severity of the current problem. A relatively new system with an isolated issue may be worth repairing, while recurring breakdowns or major component failures on an aging system may make replacement more practical.

Modern heat pumps can provide efficient heating and cooling and can be a good option for many Colorado homes. The appropriate equipment and system design depend on the home’s layout, heating requirements, existing equipment, and local climate conditions. Some homes may also benefit from a supplemental heating source.

During cold weather, a heat pump’s outdoor coil can accumulate frost. The system periodically enters a defrost cycle to melt it, which can create visible steam. That’s generally normal. Heavy ice that does not clear, however, can indicate a problem requiring professional service.

Because a heat pump may operate during both heating and cooling seasons, regular professional maintenance is particularly important. Your technician can recommend an appropriate service schedule based on your equipment and how heavily it operates.

A furnace creates heat, typically through fuel combustion or electric resistance. A heat pump transfers heat between indoors and outdoors and can provide both heating and cooling. The best option depends on your home, existing equipment, comfort goals, and efficiency priorities.

They can be. Ductless mini-splits provide zoned heating and cooling without traditional ductwork, making them useful for additions, remodeled spaces, garages, and areas that are difficult to keep comfortable with a central HVAC system.

Potential warning signs include inconsistent heating, unusual noises, leaks, pressure problems, rising energy use, or a boiler that struggles to maintain the desired temperature. Because boiler systems involve hot water, pressure, and sometimes fuel combustion, persistent problems should be professionally diagnosed.

Annual professional boiler maintenance is a good general guideline. Regular inspections can identify leaks, pressure problems, worn components, and other developing issues before peak heating season.

Boiler lifespan varies considerably based on system type, installation quality, maintenance history, water quality, and operating conditions. Rather than replacing a boiler solely because of age, consider its overall condition, efficiency, and repair history.

If replacement is becoming necessary, explore Horizon’s boiler installation services.

An older boiler does not automatically need replacement. However, frequent repairs, declining comfort, reduced efficiency, or major component problems can make replacement worth considering. A professional evaluation can compare the repair investment with the benefits and expected lifespan of a new system.

The appropriate interval depends on the filter, HVAC system, household conditions, and manufacturer recommendations. Homes with pets, high dust levels, allergies, or heavy system use may need more frequent filter changes. Check the filter regularly and replace it when it becomes visibly dirty or according to the equipment or filter manufacturer’s guidance.

There isn’t one ideal setting for every home. Indoor humidity should be balanced against outdoor temperatures and conditions inside the house. Too little humidity can contribute to dry-air discomfort, while excessive humidity can create condensation and moisture problems.

They can. Colorado’s dry climate and winter heating can contribute to low indoor humidity. A properly selected and maintained whole-home humidifier can add moisture more consistently than portable units and help improve indoor comfort.

Solutions depend on what’s affecting the home’s air. Regular HVAC maintenance, appropriate filtration, humidity control, ventilation, and air-cleaning equipment can all play a role. An indoor air quality assessment can help determine which improvements are appropriate for your home.

Warning signs can include inconsistent hot water, unusual noises, visible leaks, discolored water, or declining performance. Whether repair or replacement makes more sense depends on the unit’s condition, age, repair history, and the nature of the problem.

Lifespan varies based on the type of water heater, water quality, installation, maintenance, and household demand. Instead of relying on age alone, watch for declining performance, corrosion, leaks, and increasingly frequent repairs.

Tankless systems heat water on demand rather than continuously storing a large volume of hot water. Potential benefits include improved efficiency, a compact footprint, and a long-lasting supply of hot water when the equipment is properly sized for household demand.

Possible causes range from household demand and thermostat settings to sediment buildup, heating-element or burner issues, equipment sizing, or an aging water heater. If the loss of hot water is persistent, professional diagnosis can determine whether maintenance, repair, or replacement is appropriate.

If water is actively leaking or flooding the home, shut off the nearest fixture valve or the home’s main water supply when it is safe to do so. Avoid electrical equipment near standing water and contact a professional plumber for assistance.

Contact Horizon Services if you need plumbing service.

Possible signs include unexplained increases in water usage, water stains, damp areas, musty odors, reduced water pressure, or sounds of running water when fixtures aren’t being used. A plumber can investigate suspected leaks and determine their location and cause.

Signs that may lead homeowners to investigate water treatment include unpleasant taste or odor, sediment, mineral buildup, spotting on dishes, scale around fixtures, or concerns about drinking-water quality. Because these symptoms do not identify exactly what is in the water, testing and professional evaluation can help determine the appropriate treatment solution.

Water filtration systems are designed to address particular substances or water-quality concerns depending on the technology used. Water softeners specifically address hardness minerals such as calcium and magnesium. Some homes may benefit from one system, while others may use both.

Common signs include white or chalky deposits around fixtures, spotting on dishes and glassware, soap scum, mineral buildup, difficulty getting soap to lather, and scale around faucets or showerheads.

A water softener is designed to reduce hardness minerals, primarily calcium and magnesium, before the water is distributed throughout the home. The exact process depends on the type of system installed.

Maintenance requirements depend on the equipment and manufacturer. Homeowners may need to monitor salt levels, check for salt bridging, clean components when appropriate, and have the system periodically inspected to confirm that it is operating correctly.

Consider the system’s age, repair history, performance, availability of replacement parts, household water needs, and the cost of the current repair. A professional evaluation can help determine whether repairing the existing system or replacing it makes more sense.
