Trusted HVAC Experts in Lewisville
Lewisville residents depend on their home HVAC system to get them through both 100-degree days and 30-degree nights. For an HVAC contractor you can count on for a lifetime, you need Colony. We’ve been serving you since 1977.
You Need Heating and Cooling Service You Can Rely On
After a few hours out at LLELA Nature Preserve or shopping at The Vista, stepping back inside should feel like a reset. It shouldn’t feel as uncomfortable as the outside.
That comfort depends on a system that can keep up. In Lewisville, air conditioners run for long stretches during the summer, and heating still needs to be there when colder weather moves in. After all, you don’t want to solely rely on a few blankets to keep you warm when temperatures unexpectedly drop below 40 in the middle of the night.
Colony Air Conditioning & Heating provides full Lewisville HVAC service, from AC performance and system upgrades to heating and indoor air quality. We help you keep everything working together so your space stays consistent, no matter what the forecast looks like.
A Lewisville HVAC Company Built on Experience and Consistency
Colony has been working on heating and cooling systems across North Texas since 1977. Our company was started by Larry Everett, who learned the trade early on and went on to build a business centered around steady, dependable HVAC work. Today, we're still family-run, with the next generation involved and carrying that same approach forward.
That background shapes how we approach HVAC service in Lewisville. We've worked on systems from different decades and across a wide range of home layouts, from older equipment in Old Town to newer builds in Lakewood Hills. Years of experience have shown us how systems respond to long cooling seasons, humidity, and everyday use, which helps us make recommendations that fit the system, not just the situation.

Heating Services in Lewisville for Cooler North Texas Nights
Cold weather in Lewisville doesn’t last as long as the summer heat, but when temperatures drop into the 30s and 40s, your heating system needs to respond quickly. Homes near Castle Hills or along Main Street can lose heat faster than expected, especially during overnight cold snaps. When that shift happens, your system should start reliably and keep temperatures consistent.
Furnace Repair
If your furnace isn't starting, is cycling too often, or isn't heating evenly, it's time to have it checked. Our furnace repair in Lewisville resolves those issues so your system can run safely and consistently.
Fix Your FurnaceFurnace Replacement
Older systems can struggle to keep up when temperatures drop quickly. We provide furnace replacement in Lewisville, sized correctly for your home and matched to your energy preferences.

Routine service helps your furnace start reliably and run more efficiently through the colder months. Because Lewisville furnaces often sit unused all summer, dust can build up during that downtime, one of the more common causes of short-cycling once the system finally kicks back on. Our furnace maintenance checks key components, clears that buildup, and makes adjustments before you need the heat.

Heat pumps handle both heating and cooling, which makes them a good fit for North Texas climates. We provide full heat pump service in Lewisville, including repairs, replacements, and routine maintenance.
Learn About Heat PumpsCooling Services in Lewisville that Keep Up With the Heat
In Lewisville, it's common to see temperatures still sitting in the 80s well after sunset, especially in the middle of summer. Homes near Valley Ridge or along Hebron Parkway don't cool off much on their own once that heat builds up during the day. Your AC ends up carrying that load for hours at a time, day after day, and it doesn't take much for performance issues to show up. Our AC services in Lewisville help you stay cool all summer.
AC Repair
When your system starts falling behind, you'll usually notice uneven temperatures, longer run times, or air that doesn't feel as cool as it should. Our AC repairs in Lewisville focus on finding the source of the issue and correcting it so your system can keep up again.

In Lewisville, air quality changes throughout the year. Pollen builds up in the spring, dust settles during dry stretches, and humidity tends to hang in the air through much of the summer. Homes near wooded areas or open land closer to Highland Village often deal with these changes more noticeably.
We install, replace, and maintain air quality equipment, including:
Lewisville’s Common HVAC Problems
Lewisville’s weather affects us all, especially your HVAC system. Our 49 years here have shown us a few recurring problems that may be more common than you think.
Valley Vista Ductwork
Even if the early 2000s don’t seem that long ago, your home may feel otherwise. Homes over 20 years old typically have leaks or insulation issues. If your home is in Valley Vista, consider scheduling a ductwork evaluation.
Idly Waiting
After growing accustomed to the summer heat, sudden winter cold fronts can throw us off. The same is true for gas furnaces, which build up dust while sitting idly for the long summer months. This can lead to short-cycling and turning off suddenly when you try using it.
City Pollutants Come Indoors
High heat and humidity strain Lewisville air quality. Vehicle emissions from the nearby I-35E and Dallas-Fort Worth metroplex increase ground-level ozone, making the air quality even worse. These pollutants can follow you indoors and leave sensitive groups struggling to breathe.
Signs You Need HVAC Service
Changes in how your system runs are often the first sign that something needs attention. In Lewisville, that can show up as uneven temperatures, longer run times, or a system that doesn't adjust as well when the seasons start to shift. Common signs include:
- Your System Runs Longer but Doesn't Maintain Steady Temperatures: often a sign of worn components, restricted airflow, or buildup affecting performance.
- Airflow Feels Weaker in Certain Rooms: can point to ductwork issues, blockages, or aging duct systems.
- Energy Bills Start Increasing Without a Clear Reason: as heating and cooling equipment ages or falls out of adjustment, it takes more energy to maintain the same indoor temperature.
- The System Turns On and Off More Frequently than Usual: tied to thermostat problems or electrical issues, and can affect both heating and cooling performance.
- Certain Rooms Feel Warmer or Cooler than the Rest of the House: these problems can show up in both summer and winter, depending on how your home holds heat or cold.
- Your System is Older and Not Keeping Up: if performance has been slipping or repairs are becoming more frequent, it may be time to look at replacement options.
Why Hiring a Professional for Cooling Service in Lewisville Makes a Difference
AC systems are tied into electrical components, airflow design, and safety controls that all need to work together.
What looks like a simple issue, such as weak airflow or uneven cooling, can trace back to multiple parts of the system. Not everyone has the right tools and testing methods to safely find the source of your cooling problem. Our trained Lewisville HVAC technicians do.
It’s easy to misread the problem and make changes to your air conditioner that worsen it. Don’t risk your safety and the integrity of your home’s cooling system trying to save a buck. Skip the mistakes and call a professional who can fix it right the first time.
What HVAC Looks Like in Lewisville Homes
Homes in Lewisville range from older properties near downtown to newer construction in areas like Garden Ridge and The Realm in Castle Hills. Some homes still have original ductwork and aging central air units, while others use newer high-efficiency equipment or zoned systems.
Many homes here rely on split-system air conditioners paired with gas furnaces or heat pumps. With how long the cooling season lasts, AC systems handle most of the workload. It's common for systems to keep running well into the evening during stretches of 90-degree heat. Two-story homes can have trouble keeping upstairs rooms cool, older ductwork can limit airflow and create uneven temperatures, and in newer homes the system may run longer cycles to manage humidity during peak summer conditions.

Frequently Asked Questions
What heating systems does Colony service?
From furnaces and heat pumps to ductless heaters, we can help your home in Lewisville stay warm. We are happy to repair your system to last another winter, or replace it if it’s ready to kick the bucket.
How quickly can you get to my home in Lewisville?
In many cases, we're able to offer same-day or next-day service. During peak summer heat, availability can fill up faster, but we prioritize urgent calls when systems are down completely.
How long does HVAC service usually take?
A standard maintenance visit usually takes about an hour, while most repairs take one to three hours.
Should I repair or replace my HVAC system?
It depends on the age of your system, how often it has needed repairs, and how well it's keeping up with demand. Lewisville systems tend to wear down faster due to long cooling seasons, so older units may not perform as efficiently as they once did. We'll walk you through both options.
What HVAC brands do you service?
We service most major HVAC brands, including Carrier, Trane, Lennox, Rheem, and Goodman.
How often should HVAC systems be serviced in Lewisville?
Most systems should be serviced once a year, and twice for heat pumps. Cooling systems benefit from a check before summer, while heating systems should be looked at before colder weather sets in.
Why is my AC running but not cooling properly?
This can be caused by airflow restrictions, low refrigerant, or problems with key components. Extended run times during hot weather can make these problems more noticeable.
Do you offer maintenance plans for Lewisville homeowners?
Yes. These plans include scheduled service visits, priority scheduling, and additional benefits that help keep your system running consistently through peak heating and cooling periods.
What can I do to improve indoor air quality in my home?
Indoor air quality in Lewisville shifts with the seasons: spring pollen, summer humidity, dry-stretch dust. Improving it usually involves better filtration, humidity control, and regular system maintenance.
Do you offer financing for HVAC repair or replacement?
Yes, including promotional financing through Wells Fargo and flexible lease-to-own options through Microf for qualifying replacements.
