No equipment lasts forever, and that certainly applies to ductless HVAC systems. If yours has been in place for a decade or more and is starting to show its age, consider replacing it. You could stick with a single-zone unit or upgrade to a multi-zone system if you want to be able to handle additions more efficiently.

Replacing an aging boiler can improve efficiency, especially if you're moving from an older non-condensing model to a modern high-efficiency system.

Get a Boiler ReplacementPreventive Maintenance Keeps Your Heating and Cooling Equipment Healthy
When was the last time that your HVAC system was serviced? Many homeowners in Larkspur assume that their heating and cooling equipment doesn’t need any attention if it is working properly. Sadly, that can be an expensive mistake. Preventive maintenance is an easy way to make sure your system lives up to its potential.
When we perform maintenance on an HVAC system, we check in on all of the key components throughout each piece of equipment. That means inspecting burners, heat exchangers, blower components, refrigerant charge, and electrical connections.
In addition to making a breakdown less likely, maintenance is often required to maintain a valid warranty on new equipment.
Upgrade Your Indoor Air Quality in Larkspur
Ponderosa pine and scrub oak can lead to high pollen counts, and wildfire season can put smoke in the air throughout the region. Our collection of air quality services in Larkspur will help you make sure the air in your house is safe for your whole family to breathe.
One of the best options to upgrade your air quality is a whole-home air purification system. WYou may also want to consider a whole-house humidifier, which is particularly useful during the cold winter months when the air outside is particularly dry.
Chat with our team about what kinds of air quality upgrades may be best for your needs.
How Does Weather Impact HVAC Systems in Larkspur?
HVAC systems experience some significant and specific stresses as a result of Larkspur’s climate. The weather can change quickly and dramatically along the Denver-Colorado Springs corridor, and your HVAC equipment is likely to be strained throughout the year as a result.
- Furnace systems in ZIP 80118 often have to deal with cold overnight lows, increasing wear and tear on various parts
- Air conditioners have to ramp up quickly when the afternoon temperatures climb, leading them to run continuously
- Heavy spring snow is common in Larkspur, leading heating equipment to work all the way into April or even May
- Wildfire season can cause homeowners to keep their windows shut for weeks at a time, forcing air quality equipment to work overtime
- The high altitude of Larkspur changes combustion for the gas that may run your HVAC equipment, so it needs to be tuned properly for optimal performance
Is It Best to Repair or Replace an HVAC System?
This is one of the most common questions we receive from customers in Larkspur. It’s hard to know whether your HVAC system still has some life left in it, or if it’s time to move on. Here are some points to consider:
- Age of the equipment. In Larkspur, you’ll rarely get more than a couple decades out of your HVAC system. If your equipment is approaching those ages, replacement is likely necessary
- Frequency of repairs. An HVAC system that constantly needs to be fixed is costing you money. Replacing it will net savings in the long-run.
- Efficiency decline. Have you noticed that your utility bills keep creeping upward? That often points to an HVAC system that is using more and more energy, which is often tied to age.
- Cost of the repair. Get a quote for the HVAC repair and compare it to how much it will cost to replace the equipment. If your repair is going to be more than 30 percent of a full replacement, you’ll probably be better off having new equipment installed.
Our Proven Process Keeps Larkspur Comfortable
- Initial inspection. We’ll perform a diagnostic review of the HVAC equipment to observe the symptoms you have noticed and see which components are affected.
- Clear explanation provided. Our technician will come to you when the review is finished to explain the findings and answer any questions you may have.
- Upfront quote offered. Before we start your repair or installation, we’ll tell you exactly how much it is going to cost and how long it is going to take. We can typically start as soon as you approve the quote.
- Quality work completed. All repair and installation work is completed to manufacturer specifications. We don’t cut corners, so you can expect our work to always pass inspection and perform well for years to come.
- Final result verified. When the work is done, the system is thoroughly tested to confirm it is working properly and no lingering issues are present.
- Clean up finished. Before we leave, our Larkspur HVAC experts clean up any messes made, so your home is in the same condition as when we arrived, only now with a working HVAC system.

Frequently Asked Questions
What HVAC brands do you serve?
At Nytech, we work on all major residential brands of HVAC equipment. Some examples of the many systems we have worked on include Trane, Carrier, Lennox, Rheem, Ruud, Goodman, Amana, Mitsubishi, and Daikin.
How long does an HVAC system usually last in Larkspur?
A furnace that is properly maintained will typically last 15-20 years in Larkspur. For air conditioners, that range is more like 12-15 years in most cases. If you have a boiler, you can get even more years out of the equipment, with those units often lasting 20-30 years, or even longer, as long as they are cared for along the way.
Why is my home heating or cooling unevenly?
There are a few possible culprits for this issue, starting with an HVAC system that is not properly sized for your home. You could also have undersized or leaky ductwork, blocked or closed vents, or a failing blower motor that is limiting airflow.
Can Larkspur’s elevation affect system performance?
Absolutely. At an elevation of roughly 6,800 feet, the thin air in Larkspur directly impacts how your HVAC equipment works. There is a different amount of airflow required here to deliver heating and cooling results than what would be needed at sea level. We are a local business that understands the specific demands altitude places on HVAC equipment, so we always factor this variable into our work.
Do you offer financing for HVAC replacement?
Yes, we have financing options available if you would like to spread out the cost of your new HVAC equipment in Larkspur. In addition to our financing options, we also accept a wide range of payment methods, including Visa, Mastercard, Discover, American Express, cash, and check.

Tyler is the Man! We have had him over to do at least three projects for us and couldn't be more pleased. He is thoughtful, professional , and does a great job. After the work is completed he takes the time to explain everything he has done and how it works if that's the case. This last service he performed was complicated and time consuming for him and his partner but the final results were done well and I am very pleased. Also he arrives on time.

Gage did a great job on our furnace maintenance. Very nice young man.
Tyler quickly diagnosed problem with furnace, blown fuse. Replaced fuse. Carefully checked that system was working properly.
Outstanding Customer Service
Ryan is very knowledgeable and saved us a lot of money discovering that our thermostat has a secret menu and somehow disconnected itself from our AC. Thanks Ryan !
Braydon did an excellent job of explaining what he was doing as he examined parts of the system to determine why my gas bill has gone up since Nytech did its work. He did find a part that was not doing well and replaced it. I appreciate his patience in explaining stuff to me and am keeping my fingers crossed that the problem is now fixed and my gas bill will decrease.
Outstanding

Pleasant efficient performance
Ryan provided a timely, acurated and efficient replacement of our A/C capacitor! Ryan is a professional and competent service technician. We really appreciate the next day service. Thanks!
The technician did a good job. Overall, I am wondering why I have had annual maintenance and never needed an evaporator coil defrost control kit. Nothing has changed on this model and the weather is about the same every summer.
Prior to Josef’s leaving, I asked him “why does our thermostat say ‘waiting for equipment’?”, he said, “don’t worry, it usually takes 15 minutes or so for the thermostat and the control board to sync up.” Josef left our house over 4 hours ago, the message on the thermostat still says “waiting for equipment” and it is 77 degrees inside our home, even though we set the thermostat to a constant temperature of 68 degrees, while he was still here. Net/net, it feels like we spent over $900 to keep our home hotter than the outside temperature, this is definitely not what we had hoped for!
Service was excellent, Ricky clearly communicated status of system and two items that warranted consideration for replacement. However I didn't automatically receive an email copy of the service report and invoice and had to call the office to obtain a copy. Minor inconvenience.
Quick response and very knowledgeable
Ricky was superb, very helpful and wouldn’t think of using anyone but Nytech!

Guys did a great job fixing and doing some upgrades on my furnace!!!
Brayden found two leaks in my guest bathroom caused by poor work done with previous plumbers from other companies. He took the time to explain each step as he fixed the leaks. I appreciate his knowledge of his job and his positive attitude! I will recommend Brayden with Nytech to the Castle Rock/Larkspur community! Lisa and Carly with Nytech staff scheduled him in a timely manner (next day service) and listened well to my description of the plumbing leaks. Thank you Brayden, Lisa and Carly for your wonderful customer care!
Great Workmanship, would highly recommend
This is the second time we had Ricky out to service our heater. We will definitely request Ricky to come out again next year.
Rick was excellent. He was friendly, knowledgeable and explained exactly what he was doing.
