Filter Replacement

Your HVAC filters need to be changed on a regular basis in order for your system to work effectively. If you have yet to change your filter or you need assistance doing so, look no further than our team at Deljo Heating & Cooling.

Proper filtration will help to decrease airborne allergens such as pollens, mold spores and animal dander. MERV (Minimum Efficiency Reporting Value) ranges from one to sixteen and measures the effectiveness of an air filter. The higher the rating, the fewer dust particles and other contaminants are able to pass through it. MERV 13 to 16 is average for hospital and surgery settings. Higher MERV isn’t always better. Higher ratings mean smaller pores for air to pass through on an HVAC filter, which creates more resistance. High MERV filters also need to be changed more often, and if they are a custom size, expect to pay more.

The selection of the proper filter to meet your needs and match your equipment can be a bit overwhelming. Deljo Heating & Cooling specializes in heating, cooling and ventilation, and our certified technicians have the product knowledge and training to make informed recommendations. It is extremely important that you keep up with timely filter replacement.

Dirty filters are the leading cause of air conditioning problems and breakdowns. Changing your filter before activating your cooling equipment in the spring is the key to dependable performance and stable air quality. The filter of your furnace is its primary defense against dust contaminating the interior. Change or clean filters monthly to prevent dust from reducing airflow, which leads to much higher energy costs and overworked components. In a central air handling system, proper selection and maintenance of air filters can significantly reduce the level of indoor dust and particulates, including allergens and airborne mold. Genuine replacement filters help protect and prolong the operating efficiency of central heating and cooling systems.

My hot water heater had some leaky pipes due to corroded unions. The repair took longer than I thought due to some unforeseen circumstances. Unfortunately after the repairs the water heater stopped working...
