HVAC Installation & Replacement
Replacing a heating or cooling system starts with a look at the house: the size of the rooms, the layout of the ducts, the age of the equipment, and what has been bothering you about the comfort. We install and replace furnaces, central air conditioners, heat pumps, and ductless systems, and we size each one to the home instead of matching what was there before.
The right system varies from one address to the next, so we lay out the options side by side, including what each would involve, and you choose the one that fits. If your current system can still be repaired, we say so and price that option too.
Air Conditioning Repair, Service & Installation
An air conditioner that blows warm air, runs without cooling, freezes up, leaks, or shuts off early needs a diagnosis before anyone suggests a new unit. Cool Sunshine Heating & Air Conditioning repairs and services central air conditioning systems, installs new ones, and replaces aging units when repair no longer makes sense.
If a Cherry Creek North home has had the same air conditioner through several summers, a service visit is a good time to ask where the system stands. We check the condition of the equipment, tell you what we find, and explain whether repair or replacement is the better call.
Furnace Repair & Installation
A furnace that will not ignite, blows cold air, short cycles, or makes new noises is a problem to deal with before the next cold night. We repair, replace, and install gas furnaces, and we tell you what failed and what it would take to fix it.
Belcaro homeowners with an older furnace can ask for a repair estimate and a replacement estimate together. Seeing both makes it easier to weigh the cost of one more repair against a new system.
Heat Pump Installation & Repair
A heat pump provides both heating and cooling from one system, which makes it an option for homeowners who are replacing a furnace and an air conditioner at the same time. We install, repair, and service heat pumps, and we look at the home and the existing equipment before suggesting one.
For a Country Club home, the question is often whether a heat pump, a furnace-and-AC pair, or a combination of the two suits the house. We go over how each would run through the year so you can compare them before deciding.
Ductless Mini Split Installation & Repair
A ductless mini split heats and cools a room or zone without ductwork, so it fits additions, finished basements, converted spaces, and homes with no duct system. We size and install the indoor and outdoor units, repair existing mini splits, and service them after installation. ductless systems give a room its own temperature settings.
If a house along Steele Street has a sunroom, home office, or upper-level room that never matched the rest of the home, a mini split can give that space its own control. We walk through the layout and tell you whether ductless or another approach fits better.
HVAC Maintenance & Seasonal Tune-Ups
A tune-up is a planned visit where a technician inspects and cleans the furnace and air conditioner, which brings worn parts and minor faults to light before the equipment stops working. With one of our maintenance plans, the furnace and air conditioner are checked every year, once ahead of summer and once ahead of winter.
Homeowners along East 2nd Avenue who have never scheduled a tune-up can start with whichever season comes next. The technician checks the equipment, reports what needs attention, and leaves you with a clear picture of its condition.
Zone Control System Installation & Repair
Zone control divides a home into areas with their own thermostats and motorized dampers, so each area follows its own schedule instead of one setting for the whole house. Our crews add zoning to duct systems already in the home, repair faulty dampers and controls, and build zone control systems into a new installation when the floor plan suits it.
In a multi-level townhome or condo near Fillmore Plaza, one thermostat often struggles to keep every floor comfortable. We look at the ductwork and the layout, then tell you whether zoning, a duct change, or a ductless unit is the better fix.
Indoor Air Quality Systems & Whole-Home Humidity
Better indoor air usually comes from products installed on the heating and cooling system itself: stronger filters, purifiers, fresh-air ventilation, and humidifiers or dehumidifiers that serve the whole house. We begin with what the home has now and then suggest indoor air quality products that pair with it.
Homeowners near the Cherry Creek Shopping Center who notice dry air in winter or dust that keeps returning can start with a conversation about the symptoms. We price add-ons individually, so you can choose the ones that are worth installing.
Why Cherry Creek Homeowners Choose Us
A new furnace or air conditioner stays in the house for many years, so we begin each visit with the equipment you own today. You get an explanation of what the technician found and the repair and replacement options laid out together, and the choice is yours.
The company is family-owned and operated. Per the company’s BBB profile, Joy Valentine serves as President and General Manager and Perry Valentine as Owner and Manager, and the BBB has accredited Cool Sunshine since 1999. You can find our office at 4395 Oneida Street in Denver.
HVAC Installation, Repair, and Tune-Up Questions
Do I need HOA approval to install an outdoor AC or heat pump at a Cherry Creek condo or townhome?
Many associations set rules on where outdoor equipment can go and what it can look like, so read your governing documents or contact the board before the work is scheduled. Placement also affects how the system performs and how it is serviced. We can talk through where a unit would fit on your property, and you can take that plan to the association.
What happens during an HVAC installation visit?
Installation begins with a survey of the home and a recommendation for the equipment and where it will go. On installation day the technicians remove the old equipment where there is any, set the new system, connect it to the ducts, electrical, and controls, and then test it. Before they leave, they show you how to operate it and what to watch for.
Why does my air conditioner keep turning on and off?
Short cycling can come from a dirty filter, restricted airflow, a thermostat problem, or an issue with the outdoor unit or refrigerant. Start by checking the filter and the thermostat settings. If the system keeps cycling, switch it off and schedule a diagnostic visit, because running it repeatedly can wear out parts.
What should I do if my furnace smells like gas or burning?
If you smell natural gas, leave the house right away and call your gas utility or 911 from outside, and do not turn lights or appliances on or off on the way out. A brief dusty or burning smell the first time the furnace runs in the fall is often just dust burning off, but one that lingers or comes with smoke, odd sounds, or a shutdown warrants turning the furnace off and calling a technician.
Can a ductless mini split cool just one room, like a sunroom or home office?
Yes. A mini split serves a single room or zone with its own indoor unit and temperature setting, and that is why it suits additions, converted spaces, and rooms that run warmer or colder than the rest of the house. We look at the size of the space and how it is used so the unit we recommend matches the room.
Is a tune-up worth it if my heating and cooling system seems to be working fine?
A system that seems fine can still have worn parts, dirty components, or small faults that show up first as a breakdown. A tune-up finds those items on your schedule, before the system fails on a hot afternoon or a cold night. The technician reports what they find, so you can decide on any repairs with the whole picture.
