It’s mid-July in Fort Collins, the temperature is climbing past 95 degrees, and suddenly your air conditioning stops working. Your house warms up, the kids get cranky, and that important Zoom meeting looks increasingly uncomfortable. We’ve all been there.

Your home’s comfort depends on HVAC systems that require professional expertise to maintain and repair.

When your AC suddenly fails, you need a qualified HVAC contractor to solve the problem quickly. These professionals are the backbone of your home comfort systems. At Allen Service, we’ve seen many Fort Collins homeowners dealing with AC failures that regular professional maintenance could have prevented.

Let’s explore what HVAC contractors actually do, when you should call one, and how to avoid sweltering summer emergencies.

What HVAC Contractors Actually Do

HVAC contractors are licensed professionals who specialize in Heating, Ventilation, and Air Conditioning systems. They install, maintain, and repair the equipment that controls temperature, humidity, and air quality in your home.

When your cooling system fails and your thermostat signal doesn’t trigger any response, HVAC contractors have the training and tools to identify and fix the problem.

Most sudden system failures during the summer months require professional diagnosis and repair.

Without working heating and cooling systems, your home quickly becomes uncomfortable. Professional HVAC service isn’t just a luxury—it’s essential for maintaining a livable environment, especially during Fort Collins’ temperature extremes.

How HVAC Contractors Work

HVAC contractors provide a comprehensive range of services beyond emergency repairs. Their work typically includes:

System Diagnosis: Using specialized tools and training to identify problems with electrical components, refrigerant levels, mechanical parts, and control systems
Repairs: Replacing worn components, recharging refrigerant, cleaning critical parts, or recommending system replacement when repairs aren’t cost-effective
Maintenance: Performing routine checks and cleaning to prevent breakdowns
Installation: Properly sizing and installing new systems
Consultation: Advising on system efficiency, upgrades, and best practices

During summer in Fort Collins, local HVAC contractors handle dozens of service calls daily. Their specialized knowledge allows them to resolve issues that would leave most homeowners baffled quickly.

When to Call an HVAC Contractor

Your HVAC system works constantly, cycling on and off multiple times daily. This operation plus weather exposure inevitably causes wear and tear.

Regular professional maintenance typically doubles system lifespan and prevents costly emergency repairs.

Call an HVAC contractor when you notice:

System won’t turn on despite correct thermostat settings
Intermittent operation (works sometimes but not others)
Unusual noises from indoor or outdoor units
Visible damage to system components
System shuts off before reaching target temperature
Outdoor unit runs but air from vents isn’t cool
Unexplained increase in energy bills

In Fort Collins, we commonly see system failures from neglected maintenance and weather-related damage. Our intense sun, hail storms, and temperature fluctuations accelerate wear on outdoor components.

Addressing these symptoms promptly with professional help prevents more expensive problems later.

The Risks of DIY Repairs

Attempting DIY fixes or ignoring unusual HVAC noises is tempting, but amateur repairs often create bigger problems.

When minor issues go unaddressed, they typically develop into major system failures. A simple, inexpensive repair can quickly become a complete system replacement. A new HVAC system costs thousands more than most routine repairs.

Malfunctioning systems also waste energy, significantly increasing your utility bills. In Fort Collins’ extreme seasons, this unnecessary expense adds up fast.

Delaying professional HVAC service typically costs homeowners thousands more in the long run.

More concerning are the safety risks. HVAC systems involve electricity, gas lines, and refrigerants that require proper handling. Amateur repairs can create fire hazards, gas leaks, or harmful refrigerant exposure.

We’ve seen cases where homeowners tried DIY repairs only to need emergency service during the hottest week of the year, facing premium rates while enduring uncomfortable conditions.

DIY Maintenance vs. Professional Service

Some HVAC maintenance tasks are appropriate for homeowners:

Changing air filters regularly
Keeping outdoor units clear of debris
Programming thermostats correctly
Ensuring vents aren’t blocked

However, you should always call a professional for:

Any electrical component issues
Refrigerant handling
Gas line connections
Mechanical repairs
Annual system tune-ups
Issues affecting manufacturer warranties
Any repair you’re unsure about

In Fort Collins, professional HVAC service typically starts at $85-$150 for diagnostics, with repairs ranging from $150 to several thousand depending on the issue. While not insignificant, these costs are far less than the $5,000-$10,000+ for complete system replacement when small problems escalate.

Professional HVAC contractors have the training, tools, and experience to correctly diagnose and repair problems the first time, providing valuable peace of mind.

Professional Maintenance Services

Preventive maintenance from HVAC contractors extends system life and prevents unexpected failures. We recommend professional service twice yearly—before the cooling and heating seasons.

During these inspections, technicians perform:

Complete system cleaning (coils, blowers, drainage)
Refrigerant level checks and adjustments
Electrical connection tightening and testing
Moving part lubrication
Thermostat calibration
Air filter replacement
Ductwork inspection
Safety control verification
Carbon monoxide testing for heating systems
System efficiency evaluation

Professional maintenance also provides expert advice on optimal settings and system improvements that maximize comfort while minimizing energy use.

HVAC contractors can recommend and install appropriate protective equipment to prevent premature system failure for homes in older Fort Collins neighborhoods with power quality issues.
