Our team specializes in installing a wide range of heating systems, ensuring proper setup and long-term functionality. We also offer comprehensive installation services for new and upgraded HVAC systems, insulation, and related home comfort solutions. Whether you have an older furnace that needs attention or you’re considering a complete upgrade, we handle it all. Installation costs for forced-air systems can range from $5,000 to $10,000, depending on the scope and requirements.
Key services we offer:

- Annual tune-ups and preventive maintenance
- Thermostat upgrades including smart thermostat installation
- Zoning solutions for better temperature control throughout your home
Our technicians are licensed, background-checked, and trained on modern high-efficiency equipment as well as older systems commonly found in Central Ohio homes. We understand that not every house is the same, and we adapt our approach accordingly.
Before any work begins, we provide transparent, upfront pricing and review all options with homeowners. No surprises, no hidden fees. For larger projects like full system replacements, we can often offer flexible financing options (subject to approval) to help you manage the investment.
Furnace Repair, Installation & Replacement
Gas and electric furnaces remain the primary heating systems in many Central Ohio homes. We offer fast response times for furnace repairs and installations, ensuring your home stays comfortable without delay. High-efficiency gas furnaces are ideal for cold climates where powerful heating is required. Furnaces use natural gas, oil, or electricity to blow warm air through ducts. These units are workhorses, but aging furnaces—especially those 15 to 20 years old or older—often need frequent repair or eventual replacement.
Common Furnace Problems We Handle
| Problem | What It Might Mean |
|---|---|
| No heat output | Ignition failure, thermostat issue, or gas supply problem |
| Short cycling | Overheating, dirty filter, or faulty sensor |
| Strange noises | Worn bearings, loose components, or ductwork issues |
| Burning smells | Dust buildup or electrical problems |
| Frequent pilot issues | Thermocouple failure or gas valve problems |
| Rising utility bills | Declining efficiency or system malfunction |
Our Furnace Repair Process
When you call us for furnace trouble, here’s what to expect:
- Thorough inspection of all system components
- Safety checks for gas leaks and carbon monoxide
- Clear explanation of our findings in plain language
- Written repair options so you can make an informed decision
Sometimes, repair isn’t the most cost-effective path forward. We recommend replacement when you’re facing repeated failures, a cracked heat exchanger, or when your unit’s efficiency falls far below current standards. A new high-efficiency furnace can deliver significant savings on your monthly energy bills while providing dependable heating for years to come.
We install high-efficiency furnaces from trusted manufacturers and typically provide free replacement estimates. Our team will guide you through sizing and efficiency ratings (AFUE) so you choose a unit that fits your home and budget. We can also replace furnaces as part of full HVAC system upgrades, coordinating ductwork improvements and thermostat upgrades at the same time.
Heat Pump & Boiler Heating Solutions
Heat pumps are increasingly popular in both Ohio and Florida for their ability to provide efficient heating and cooling in one system. Unlike furnaces that generate heat through combustion, heat pumps transfer heat from outdoor air or ground sources into your home. This makes them significantly more energy-efficient for many applications.
Heat Pump Services
Our heat pump expertise covers:
- Troubleshooting poor heating performance
- Diagnosing and fixing refrigerant issues
- Addressing outdoor unit icing problems
- Resolving airflow restrictions
- Correcting thermostat miscommunication
We install new high-efficiency heat pumps, including variable-speed and cold-climate models where appropriate. These systems can integrate with existing ductwork or work as ductless mini-split configurations for homes without traditional duct systems.
Boiler and Hydronic Systems
Some Central Ohio homes and light commercial buildings still rely on boilers and hydronic systems with radiators or in-floor heating loops. We can inspect, repair, and replace these systems when needed.
Our boiler services include specific safety and efficiency checks:
- Venting inspection for proper exhaust
- Pressure monitoring and adjustment
- Leak detection throughout the system
- Circulation verification through radiators or in-floor loops

Emergency Heating Service & Seasonal Maintenance
Losing heat during a freezing Central Ohio night can be both uncomfortable and dangerous, especially for children, older adults, and anyone with health concerns. When your heating system fails at 2 AM in January, you need someone who will answer the phone. Many HVAC companies offer emergency repair services to ensure customer comfort during heating failures. Customers may also receive a message or notification updating them on the status of their emergency service request.
24/7 Emergency Heating Support
Dor-Mar offers emergency repairs for urgent situations like:
- Complete heat loss
- Suspected gas leaks (call your gas company first for active leaks, then call us)
- Carbon monoxide detector alerts
- Furnace making dangerous sounds or smells
When we respond to emergency calls, expect rapid response, safety-first diagnostics, and clear communication about your options. If a permanent fix isn’t possible immediately, we’ll implement temporary measures to keep you safe until we can complete the repair.
The Value of Preventive Maintenance
The best way to avoid emergency repairs is to prevent problems before they start. Annual furnace or heat pump tune-ups before the heating season reduce breakdowns, improve efficiency, and help validate manufacturer warranties.
Typical tune-up tasks include:
- Cleaning burners and critical components
- Checking electrical connections
- Verifying gas pressure
- Testing safety controls
- Measuring overall system performance
We recommend scheduling maintenance in early fall—September through October—to avoid the peak-season rush and reduce the risk of mid-winter surprises. Your heating system works hardest when you need it most; give it the care it deserves before winter arrives.
Beyond Heat: Plumbing, Electrical & Indoor Air Quality Support
True home comfort depends on more than just your main heating unit. Dor-Mar offers additional services that directly support heating performance, safety, and overall comfort throughout your home. We also provide installation and maintenance of home backup generators to ensure continuous power during outages. Additionally, duct cleaning and sealing are important services we offer to improve indoor air quality.
Plumbing Services That Tie Into Heating
- Water heater repair and replacement
- Tankless water heater installation
- Fixing leaks that can affect comfort and utility bills
Our plumbers understand how water heating integrates with your overall home comfort system.
Electrical Services Related to Heating
- Dedicated circuits for high-efficiency HVAC systems
- Thermostat wiring upgrades, including smart thermostat installations
- Safety checks on electrical panels feeding heating and cooling equipment
Proper electrical work ensures your heating system operates safely and efficiently.
Indoor Air Quality Options
Winter air in Ohio can be brutally dry, which affects both comfort and health. We offer:
- Whole-home humidifiers
- Air cleaners and high-MERV filters
- Duct cleaning and sealing services
These products work alongside your heating system to improve air quality and reduce strain on your equipment.
We can often bundle some of these services during a single visit. For example, combining a furnace tune-up with a water heater inspection or filter upgrade saves you time and reduces disruption to your day.
Dor-Mar Home Comfort Membership
The Dor-Mar Home Comfort Membership is our maintenance program designed to keep heating, cooling, and related systems running reliably year-round. It’s the simplest way to stay ahead of problems instead of reacting to them.
Membership Benefits
| Benefit | What It Means For You |
|---|---|
| Scheduled annual tune-ups | Heating and cooling system maintenance before peak seasons |
| Priority scheduling | Get service faster during busy winter and summer months |
| Repair discounts | Save money when something does need fixing |
| Peace of mind | Predictable comfort costs with fewer surprises |
Members often see lower energy bills and fewer emergency breakdowns because their systems are cleaned and adjusted before peak-demand months. It’s the difference between catching a small problem in October and dealing with a major failure in January.
How It Works
Enrolling is easy—you can sign up online or over the phone. Membership is ideal for homeowners who plan to stay in their home and want predictable comfort costs without the hassle of remembering to schedule maintenance.
Example scenario: A Central Ohio homeowner schedules their fall tune-up as part of their membership. During the inspection, our technician notices a failing ignitor—a part that would have caused a complete heating failure by mid-January. We replace it during the scheduled visit, and the homeowner stays warm all winter without an emergency service call.

Frequently Asked Questions About Home Heating Services
How often should I schedule professional maintenance for my furnace or heat pump?
Schedule heating maintenance once a year, ideally in early fall before consistent cold weather arrives. This timing allows you to address any issues before you actually need your system to perform at its best.
Heat pumps used for both heating and cooling benefit from twice-yearly checkups—once in spring before cooling season and once in fall before heating season. This keeps both functions running efficiently.
The Dor-Mar Home Comfort Membership automates these visits so you don’t have to remember to call each season. We’ll reach out to schedule your tune-up at the right time.
How do I know if it’s time to replace my old furnace instead of repairing it again?
Several indicators suggest replacement makes more sense than another repair:
- Furnace age of 15 to 20 years or older
- Frequent repairs adding up over recent seasons
- Uneven temperatures throughout your home
- Rising gas or electric bills despite consistent usage
- Safety issues like a cracked heat exchanger
Our technicians can provide a side-by-side comparison of repair versus replacement costs, including estimated energy savings from a new high-efficiency unit. We offer free estimates on new systems so you can make an informed decision without pressure. Exclusions apply to certain promotional offers, so ask about current terms.
Can Dor-Mar install smart thermostats with my existing heating system?
Yes, we frequently install and configure smart thermostats on compatible furnaces and heat pumps. These devices can improve comfort and energy control by learning your schedule and allowing remote adjustments through smartphone apps.
A quick system and wiring check may be needed to verify compatibility, especially in older homes or with older equipment. Our technicians can help you set up schedules and app controls during the installation visit so you’re ready to use all the features right away.
Do you offer any financing options for new heating systems?
Dor-Mar typically offers financing options (subject to credit approval) to help spread the cost of a new furnace, heat pump, or full HVAC system. This makes it easier for homeowners to invest in high-efficiency equipment without a large upfront charge.
Contact us directly or visit our site to see current financing promotions, terms, and any seasonal rebates. We encourage you to request financing details during your free replacement estimate so you can review payments alongside system options.
