Heating and air conditioning systems will exhibit certain tells, letting you know when it’s time for repairs. Some of the usual symptoms of problematic comfort systems include bad odors, unusual sounds, poor airflow, and higher indoor humidity. More serious issues can include refrigerant leaks with air conditioners and gas leaks with gas-powered furnaces.
No matter the issue, schedule repair services with Dog House as soon as you notice there’s a problem. It’s not a good idea to wait and hope the issue goes away on its own. Ignoring the signs you need HVAC repair work in Lisbon will mean you’ll have to pay more for the service since it will just get worse and require more effort to fix.
It’s necessary to keep up with repairs for your heating and air conditioning units, but sometimes, even these fixes might not solve your issues. If you’re always scheduling repairs only for your system to go back to struggling to perform as it should, then you probably need a complete replacement.
Some signs to watch out for include higher monthly energy bills. Paying more than you need to in order to run your heating or cooling unit can mean you have an efficiency issue. Also take note of the age of your HVAC units. If they’re approaching 15-20 years old, then consider a new system installation.
You’ll get many benefits with an upgraded comfort system.
Modern features
Improved overall comfort

Noah Brooks and Liberty did a very professional job on our annual service as well as fixing two issues.
