Frequently Asked Questions

These are a couple of questions we get often about Raleigh area HVAC systems:

Though there can be a bit of wiggle room, generally speaking, you should have your air conditioner serviced twice yearly: once in the fall and once in the spring. This is to ensure that it’s clean, that its parts are in good shape, and that it’s operating as optimally as possible.

You can expect to replace an AC unit every 10-15 years unless you experience problems with the unit. Be sure to keep up with maintenance and proper storage of the unit once the weather becomes cold.

First things first, a typical residential HVAC system lasts between 10–25 years, but let’s look at that in closer detail. How long your heating and cooling appliances are expected to last depends on a few things, including: Your home’s current HVAC system setup, like whether your home has a boiler or a furnace.

Here are just a few ways:

  1. Check seals on windows, doors and appliances.
  2. Fix leaky ductwork.
  3. Give your thermostat a nudge.
  4. Adjust your fridge and freezer temperature.
  5. Take shorter showers.
  6. Replace your showerhead.
  7. Don’t wash clothes in hot water.
  8. Fix leaky faucets.

Between 4 and 8 Hours.

If you are replacing both your furnace and air conditioning unit at the same time, then the job will take between 8 to 14 hours. The length of time will vary depending on the size of the unit and your home and where it is located in your home.

HVAC stands for Heating, Ventilation, and Air Conditioning.

It’s recommended to have your HVAC system serviced annually, ideally before the start of each heating or cooling season.

You can improve efficiency by regularly changing air filters, sealing ducts, and ensuring your home is well-insulated

Unusual noises can indicate various issues, such as loose parts or a malfunctioning compressor. It’s best to have a professional technician inspect it.

You can save on energy bills by setting a programmable thermostat, sealing leaks, and ensuring your system is well-maintained.

A comfortable range is typically 72-78°F (22-26°C), but the ideal temperature varies based on personal preference and the season.

Air filters should be replaced every 1-3 months, depending on usage and the type of filter.

It’s highly recommended to hire a professional HVAC technician for system installation to ensure safety and efficiency.

A furnace uses fuel to heat air, while a heat pump transfers heat from one place to another, serving as both a heating and cooling system.

The best system depends on your specific needs, budget, and home size. Consult with a professional to determine the most suitable option.

Inadequate cooling or heating could result from low refrigerant, a dirty filter, or a malfunctioning component. A technician should diagnose the issue.

Yes, regular maintenance is essential to prevent potential issues and extend the lifespan of your HVAC system.

You can enhance indoor air quality by using air purifiers, changing filters, and ensuring proper ventilation.

Many HVAC systems are compatible with smart thermostats, allowing you to control and schedule temperature settings remotely.

The cost varies widely based on factors like system type, size, and your location. A professional quote is the most accurate estimate.

Yes, most HVAC systems come with warranties. Be sure to understand the warranty terms and conditions for your specific system.

Dehumidification can be achieved by using a dehumidifier, ensuring proper ventilation, and maintaining your HVAC system.

Many HVAC companies offer 24/7 emergency services. Check with your local provider for their emergency contact information.

For winter, ensure your system is in good condition, change filters, and seal drafts. For summer, clean or replace filters and check for any blockages in the system.

Look for signs like inconsistent temperatures, unusual odors, high energy bills, or strange noises coming from your HVAC system.

The decision depends on the age, condition, and efficiency of your current system. A professional assessment can help determine the best option.

Repair costs vary depending on the issue. It’s best to get a quote from an HVAC technician after an inspection.

Many HVAC companies offer financing options to help with the upfront costs of a new system. Inquire about available financing plans.

Duct cleaning is recommended every 3-5 years, or sooner if you notice dust or debris coming from your vents or have allergies.

Central air systems use ducts to distribute air, while ductless mini-split systems offer zoned cooling without ductwork.

Water leaks could be due to clogged condensate drains or refrigerant issues. It’s best to call an HVAC technician for inspection and repair.

Most standard HVAC systems won’t work during a power outage. Consider investing in a generator or backup heating/cooling source.

Many smart thermostats are compatible with older systems, but it depends on the specific HVAC setup. Consult with an HVAC professional for guidance.

Maintenance agreements often include regular tune-ups and discounts on repairs, which can extend the lifespan of your HVAC system and save you money.

Options include upgrading to energy-efficient equipment, setting a programmable thermostat, and using renewable energy sources.

SEER (Seasonal Energy Efficiency Ratio) measures efficiency over a cooling season, while EER (Energy Efficiency Ratio) represents efficiency at a specific temperature and humidity level.

Yes, you can use alternative heating sources like fireplaces or space heaters, but ensure they’re used safely and efficiently.

Simple steps like checking the thermostat settings, changing air filters, and resetting circuit breakers can resolve minor issues.

The ideal indoor humidity level is around 30-50%. A whole-house humidifier or dehumidifier can help maintain this range.

The most expensive repair on a furnace is often related to the heat exchanger. Replacing a heat exchanger can be costly due to the labor-intensive nature of the repair and the high cost of the part itself. Additionally, if the furnace is older or the damage is extensive, it may be more economical to replace the entire furnace rather than just the heat exchanger.

We had a small emergency, the AC stopped working right before we were to have a party. They showed up, took care of the issue, then we're gone before guests arrived. Super helpful and I'm so grateful they were able to come at 5:15 at night!! -Oct 2020Update 6/2023 came back from traveling and called comfort hounds late night after we had a big ordeal up in the attic and 78° + climbing. Rob got us on the schedule ASAP. The very next morning the tech was out. We had him check everything, needed to replace a few things and everything was working well. After talking with Rob, we realized we needed to insulate the new part and they came right back out to do that. Fast forward, we had suspicion that the damper actuator was going bad or finally died, even though it was working fine during our system check and right after we spent hours the first night troubleshooting- naturally! Usually we reset it and it kicks on. For sure this time, it was not working, BUT within minutes Rob was here. He got it changed out and we have crisp AC on the second floor and no issues with it shutting off. I'm thankful for Comfort Hounds' responsiveness and kindness, knowledge and dedication to making everything right. They have always taken care of me and I hope to continue doing business for years to come. Thanks guys for getting us up and running. See you in the fall for our winter check!

As a new homeowner, my HVAC system needed help. The AC, duct-work, and furnace were all breaking down. Rob and his team at Comfort Hounds came out and fixed everything.- The AC works better and doesn't have to run as often.- The ducts now have dampers so the heat and air spread more evenly throughout the house.- The furnace heats our house faster and easier than before.- There are no more big swings in temperature.I could go on, but the point is that our HVAC system is now running properly thanks to Comfort Hounds.Next is the price, HVAC repair is always expensive, but Comfort Hounds has the most competitive pricing out of the 4 other HVAC companies I've used in the past.Lastly, Rob and his team were patient with us. They stayed well past the allotted time to fix our HVAC system. They spent time with us explaining how we could keep our system running well and how to save money on our electricity bill. They never rushed us despite having other appointments to make.I will continue using Rob and his team for their skills, price, and patience. I highly recommend them.

Great company-friendly-professional-timely. They have been maintaining my hvac for two years. Quick to return calls/texts and provide service. Old system finally needed replacement and they were able to do so quickly and provide financing that met my budget requirements.

Very impressed with Rob’s knowledge and professionalism. He is also very upfront and honest - and fixed what turned out to be a very small issue with my system instead of trying to sell me on a new one. Will be calling him for any future needs!

Quick call back, same day service for my broken AC. Rob broke down pros and cons of repair vs replacing for my unit and went the extra mile to be sure I had the right system size and HVAC coil to match my heat pump and my sq footage for my house. He also did some maintenance and extra work on issues when installing the new system to be sure it could work at full capacity.Great communication and didn't treat me different being a female. I'll definitely be returning!

I had an excellent experience with comfort hounds. My AC had gone out and was getting uncomfortably hot in the house. I have called several different companies and nobody had an appointments for days. Then I noticed comfort hounds said they were open after hours and within 20 minutes of my call they were here working on my air conditioning and had it repaired and working at 7:00 in the evening. I was really impressed with their quick and courteous service. I went ahead and signed up for the twice a year maintenance check so that I don't end up in an emergency situation again.

Rob and the guys were very responsive when others put me off for 1.5weeks. They came out and gave me honest, up front opinion. They weren't trying to pitch a new system on me just for the sake of sales. They told me what was wrong, estimated cost of repair into a dying system. It was just time and I finally decided to buy. The process was simple and fast. System ordered and installed when promised. Installation was faster than anticipated. New system far exceeds performance of older system. Highly recommend these folks - they won't jerk your chain.

Really happy I went with these guys. My HVAC went out and they were able to come diagnose the problem very quickly. While they had the parts on the truck and could do the repair same day I opted to replace my system. Rob was very knowledgeable of his products and what would work best for my home and able to give me a quote within 24 hours. Rob called to check on us after a particularly cold Sunday night to see if we needed space heaters or anything, super thoughtful. The new system 100% solves the problems I had with the old system - my upstairs is finally warm.Definitely would recommend to a friend.

Rob is fantastic. He is always responsive and genuinely tries to help you with your issue as quickly as possible. He also does a great job of explaining what the issue is and what needs to be done to fix it. He’s always willing to talk through options and help you make the best decision. We’ve trusted Rob for over 3 years with all our HVAC needs and I can highly recommend him.
