To set up a safe consultation or appointment with an HVAC technician during the COVID-19 pandemic, start by comparing technicians in your area in an online search. Message or call technicians to ask whether they can perform a consultation over the phone or even over a video call. This way, they can assess the problem without increasing the risk of virus transmission by visiting your house. 

If it turns out the service is essential, you’ll need to follow CDC guidelines as well as local government guidelines to ensure everyone’s safety.

Currently, governments on both the federal and local levels are updating guidelines on what qualifies as an essential service. To see whether an HVAC technician is considered an essential service during the COVID-19 pandemic, check your city or state’s government website. 

For federal guidelines, check CISA’s Identifying Critical Infrastructure During COVID-19 page, which identifies 16 critical infrastructure sectors during the crisis. But note that not all jurisdictions follow CISA’s definitions of critical infrastructure.

If you decide to hire a technician for an HVAC repair or installation project, practice current social distancing guidelines. This may require remaining outside while the technician works or ensuring the technician can work in a sectioned-off area or outbuilding.

Comply with social distancing guidelines while the technician is performing work. Do not make physical contact with technicians, maintain at least 6 feet of distance between you at all times, sanitize all involved spaces and surface and pay using a digital platform instead of cash or a check.

The use of digital payment platforms -- like Google Pay, PayPal, Zelle, Venmo and Square Cash -- is common among air conditioning technicians. Currently, the COVID-19 pandemic is improving the adoption of these platforms as a means of helping social distancing.

As you compare local air conditioning technicians online, contact them to see if they’ll accept digital payments. Also, discuss strategies for completing the job while complying with safety guidelines for reducing the risk of exposure.

Heating typically constitutes 42 percent of a homeowner’s utility bill, according to Energy.gov. If your heating bills are through the roof, it might be time to compare what you’re spending on utility bills to the cost of a new furnace. A new furnace can cost between $1,000 and $2,700 for standard big-box forced-air furnaces, and more than $10,000 for advanced technology or high-end brands.

With a new furnace you could lower your total energy bill by 30 percent while also reducing your carbon footprint. To achieve these savings, Energy.gov recommends combining proper equipment maintenance, insulation, air sealing, strategic thermostat settings, and — of course — energy-efficient HVAC equipment. The furnace cost you’re facing may seem large upfront, but should save you money in the long term with improved home heating at a lower cost. Furnace cost is dictated by brand, efficiency, technology and the British thermal units (BTUs) needed to heat your home. AFUE is another important acronym. It’s short for annual fuel utilization efficiency, and it represents what percentage of the fuel becomes heat for the home. Energy.gov explains that an AFUE of 90 percent means 90 percent of the energy in the fuel is used to heat the home, and the other 10 percent escapes.

The national average for furnace replacement is between $1,800 and $2,500. The cost can range dramatically higher depending on the model of furnace you select, any repair work you require, your location and the cost of installation. Furnace installation costs can be more than the furnace itself due to the cost of doing business and the expertise needed to install the HVAC equipment. Installing a new furnace generally requires technical know-how and the proper tools and licensing. It’s best to hire a pro and budget for furnace installation rather than risk potentially unsafe DIY installation. This will ensure your home’s safety. Check to see if your HVAC contractor has the proper licensing to do the job. If you need duct repair or replacement, expect to pay more for your furnace installation costs. The price for duct repair could be an hourly rate ranging on average anywhere from $85 to $150 per hour, with additional costs for parts.

Because most HVAC systems are located in the home, it’s likely that an HVAC technician would need to enter yours when working on the projects. However, there might be exceptions. Some HVAC systems are located in garages or in areas of the house that are sectioned off. During the consultation, ask your technician if they'll need to enter your home.

When you contact local technicians, ask if they’ll perform a video call in place of a traditional consultation. Be sure to send all materials like photos and documents digitally, and comply with all relevant guidelines.

The cost to replace your gas furnace will vary based on the type and size of furnace you select, labor and installation costs, and any repairs your HVAC system may need. Nationally, average HVAC prices for a heating specialist range between $1,800 and $2,500. It’s important to select the right size gas furnace for your heating needs. A furnace that’s too small won’t heat your house properly, while a furnace that’s too large will run inefficiently, cycling on and off and likely breaking down sooner. HVAC specialists calculate your exact heat needs by measuring your home and incorporating variables such as the regional climate and your home’s level of insulation. Retail pricing for gas furnaces can range from $650 up to $3,000 and more. The higher the AFUE (annual fuel utilization efficiency) rating of the furnace, the more efficient it is at turning fuel into heat and the lower your carbon footprint and utility bill will be. HVAC installation costs are often based on an hourly rate and can range from under $50 to over $100 per hour, depending on the company and the furnace being installed. Higher-end furnaces cost more to install because they require added labor and expertise. For a typical installation, it might take two HVAC installation pros one day or less to remove your old furnace and replace it with a new one.

If your furnace needs to be repaired, you’ll want to find a qualified heating, ventilating and air conditioning (HVAC) repair technician. Each state has its own licensing requirements; some require all HVAC technicians to have an HVAC license, while others only require someone operating an HVAC service and installation company with employees to hold a contractor’s license. For example, in Alabama, the Alabama Board of Heating Air Conditioning, and Refrigeration Contractors regulates licensing, while in Kansas there is no state regulatory body and HVAC licensing can vary by region. For simple furnace repairs like changing out a filter, a trusted handyman can probably handle the job, but a trained professional should be hired for tasks like replacing a gas valve, installing a new inducer fan motor or other critical furnace repair jobs that involve dealing with gas leaks or other dangerous conditions.

When your furnace isn’t regularly serviced it can operate less efficiently. This increases your energy bills and also prevents your furnace from keeping your home as warm as you like. Keep your furnace properly maintained with regular service. The national average furnace service cost is between $60 and $80. Companies may offer tuneup specials that cover all the necessary testing, tightening, measuring and cleaning to keep your equipment running at top efficiency. If you have a newer system, furnace service costs may be covered by your warranty. Outside of warranty, a basic tuneup might start at $58 and a more advanced maintenance cleaning could be over $120. Here are some signs your furnace may need service:

• The furnace has stopped functioning entirely.
• The temperature cannot be regulated.
• Rooms in the home are either too hot or too cold.
• The heated air coming from the furnace smells like gas.
• The thermostat isn’t working.
• Strange noises are coming from the furnace.
